Sheep eimriosis is one of the most important and common disease which infects sheep in all ages but it is more effective in lambs. The diarrhea with or without blood is the main signs of infection. Eimeria protozoan required single host to complete its life cycle which pass in different stages including schizogony, gametogony and sporogony. The study was designed for detection of sheep Eimeria species through the molecular method. This study was conducted in Al-Diwanyah province during the winter months of 2019. In which 200 sheep fecal samples were collected and examined traditionally to investigate the Eimeria oocytsts. Ninety-seven samples of highly intensity infection with Eimeria oocysts were selected to subject for DNA extraction process. The extracted DNAs were tested through amplification of internal transcribed spacer 1 (ITS-1) gene by conventional PCR, and then phylogenetic analysis was made to diagnose the sheep Eimeria species. All samples that examined microscopically were showed positive results of infections with Eimeria protozoan. Out of 97 molecularly examined samples, forty-five (46.39%) were given positive result in conventional PCR technique, where Eimeria spp. detected through succeeded amplification of internal transcribed spacer 1 (ITS-1) gene. Then phylogenetic analysis referred to that there are five species of Eimeria confirmed in sheep in Al-Diwanyah province including 6 (33.33%) samples diagnosed as E. ahsata, 4 (22.22%) samples E. weybridgensis, 3 (16.66%) samples E. ovinoidalis, 3 (16.66%) samples E. bovis and 2 (11.11%) samples E. auburnensis. So, the Eimeria protozoan appears as an endemic parasite and can infect sheep with different species in study area. The sheep can infect with both specific and nonspecific species.

The current work on mosquito larvae was performed to evaluate the resistance status of larvae to deltamethrin (DM) and to detect if the larvicidal activity (LA) of this chemical could be synergized after exposing the larvae to cinnamaldehyde (CD). Here, 200 Aedes albopictus larvae were employed for the experiment and were divided randomly into 2 groups (100/each group and placed in petri-dishes (PD), 10 larvae/PD), and they are the DM group (1ml of 0.04 mg/l in 99ml of distilled water (DW) was placed to each PD) and the DM+CD group (1ml of 0.04 mg/l and 1ml of 0.9mg/l respectively were placed with 98ml DW in each PD). The experiment was lasted for 24hrs. Larvae were detected to have resistance against DM as 45% to 60% of the larvae were killed by the DM, 40% to 55% resistance rate. However, when evaluating DM activity with the use of CD, the LA was synergized showing mortality in 87% to 92% of the larvae in which a significant increase in the mortality in DM+CD group was noticed more than that in the DM group. Furthermore, RT-qPCR was run to identify the expression status of the P540 monooxygenase gene, Cyp6p15, and found that the gene expression was significantly inhibited in the DM+CD group when comparing that in the DM group that showed overexpression of this gene. This work results provide viable information about the potential activity of the cinnamaldehyde in synergizing the larvicidal activity of deltamethrin.

The aim of the study is characterizing of hydatid cysts that have been isolated from sheep and cow liver fertile hydatid cysts using mitochondrial cytochrome c oxidase subunit 1(cox1) gene. DNA samples of nineteen sheep and one cow were extracted from protoscoleces and germinal layers of the parasites in Koya city-Erbil, Iraq, using specific extraction procedures. Mitochondrial cox1 gene region was amplified by polymerase chain reaction (PCR), and the expected gene sizes were confirmed by gel electrophoresis. All DNA isolates were then sequenced. Nucleotide sequence alignments were then performed to verify the sequenced isolated according to the database, which showed that all samples were belonging to the (G1) sheep strain. Phylogenetic analysis was also carried out for the sequenced isolated to find out the highest similarities with closest organisms to E. granulosus’ conserved gene and to reveal sharing common ancestor, which has been confirmed. Electrocatalytic reduction of DNA where detected through applying cyclic-voltammetry technique, which referred to the environmentally strong protection features of these strains against any effects of external factors, such as heavy metals and has revealed the secret behind the potent preservation of the DNA structure of this parasite from being affect by mutations, or alterations, along the different lineages over a long period of time.

The current study investigated the effect of acidophilus plus probiotic in the immune activities in mice to infestation with the cystic echinococcosis. Two dilutions of the probiotic bacteria 9*106/0.1 ml, 30*103/0.1 ml CFU were used, by intraperitoneally injection in the experimental animals, pre and post infections with protoscoleces of Echinococcus granulosus. Before infection remedy comprised injection by acidophilus plus twice with 72 hours interval, on the seventh day, animals were injected with protoscoleces intraperitoneally, after infection remedy implicated injection of animals with protoscoleces of Echinococcus protoscoleces first, next to 72 hours, probiotics were inoculated intraperitoneally. Many criteria were taken into consideration including, numbers, weights, diameters and percentage reduction of hydatid cysts of treated mice in contrast to the animals infested with only. The study showed a decline in cysts including their diameter, weighting, digit, accompanied by increasing the percentage reduction of hydatid cysts in treated mice, the highest percentage reduction was 98.03%, at both dilutions, 6 months post infection, and the minimum cysts number was 0.8 in comparison with the control group 39.4, with significant difference, in the same experiment. The minimum cysts weight was 0.0104 gm, 6 months post infection at the dilution 9*106/0.1 ml CFU, compared with the control group 0.442 gm. The smallest cysts diameter was 0.057 mm in comparison with the control group 0.882 mm at dilution 9*106/0.1 ml CFU, 6 months post infection. Acidophilus plus it may well be deduced that probiotic bacteria can be used as medicinal and remedial method against infection with hydatidosis.

The study was carried out through the clinical examination on the skins of sheep and goats to identify the quality and processed in the tanneries. Parasitic skin diseases caused by ectoparasites such as mange mites, lice, and ticks are among these threats resulting in a serious economic loss to the tanning industry and the country as a whole. Out of 38066 sheep and 9889 goats examined in Sulaimani slaughterhouse in spring season 2017, shows statistically significant P<0.05 between sheep and goats prevalence; 9.35% and 7.43% respectively with one or more ectoparasites. Three different of ectoparasites were infested in both sheep and goats namely; hard tick, lice and mite. Five species of hard tick (Ixodidae) were identified in sheep and goats as follows; Boophilus spp 3.68% and 14.16%, Rhipicephalus sanguineous 12.47% and 28.63%, Rhipicephalus turanicus 7.50% and 15.96%, Hyalomma a. anatolicum 11.90% and 31.30%, Hyalomma marginatum 9.26% and 9.95%) respectively. Two species of lice were identified in sheep namely, Damalinia ovis 17.74% and Linognathus stenopsis 13.63%, and D. caprae 10.97% and L. stenopsis 6.22% on goats. Highly infested were identified with mite on sheep include Psarcoptic scabiei 13.83% and Psoroptic ovies 9.98%, while only one species founded in this study in goats namely, Psarcoptic scabiei 22.79%. The overall number of skins refused to tanning industry 164 (4.61%) in sheep and 116 (15.78%) in goat. The difference in the prevalence of skin disease infestation between refused skin in both sheep and goats were statistically significant in ruminants (P<0.05). This paper deals with major skin defects in occurrence by ectoparasites sheep and goats in Sulaimani province.

Camel internal parasites are among important camel health problems which are often affecting camel production and productivity. A cross-sectional study was carried out in camels to study the major helminth parasites in selected districts of Afar regional state of Ethiopia. Coprological examination and key informants interview were done to collect the required data in the study areas. Fecal sample was collected from a total of 384 camels and about 76.04% (292) were found to harbor at least one helminth parasite. According to the flotation and sedimentation techniques, Trichostrongyle egg (71.6%) was found with higher prevalence followed by coccidia (69.9%). In the mixed infestation, occurrence of two parasites together (31.9%) was with higher prevalence and occurrence of five parasites together (4.4%) was the lowest one. According to the key informants, the occurrence and transmission of these parasites is higher in the study areas due to aggregation of camels in the cross-border salt trade and mixing of camel herds at watering and feeding points. Furthermore, there was no adequate seasonal and programmed treatment due to drug shortage. Therefore, collaborative parasitic control and prevention measure and public education on modern camel husbandry should be delivered.

Research was undertaken to establish an inventory of ticks on dogs in the north east of Algeria. In the first aspect of study, a survey aims to identify of Ixodidae infesting the dogs in bioclimatic different areas and to determine the risk factors. This work took place between 2006 and 2012. The results of the collections show that all the dogs, which were the subject of this survey, are infested by ticks during the period between March and August in different areas of the northeastern of Algeria. Rhipicephalus sanguineus is the predominant tick species. It has been observed with a frequency of 88 % in the area of El-Tarf, 100 % in Souk-Ahras, 95 % in the Tébessa region and 72 % in Guelma, (average of 89 %). Climatic conditions seem to play the essential role for this distribution of ticks. The other tick species collected are: Ixodes ricinus, Rhipicephalus turanicus, Haemaphysalis punctata and Hyalomma anatolicum. The latter were present with very low a proportion, which gives them the appearance of accidental parasitism in dogs. Rhipicephalus sanguineus has significant infestation intensity in spring and summer, peaking in August in the semi-arid region (Souk-Ahras). In humid regions (El-Tarf), the peak of infestation recorded by this arthropod is in April. The second aspect of study of the seasonal dynamics of Rhipicephalus sanguineus shows the seasonal nature (Spring-Summer) of the brown tick of dog.

Pseudomonas (P.) aeruginosa possesses a variety of the virulence factors that may contribute to its pathogenicity, such as exotoxin A (toxA) and exoenzyme S (ExoS). The principal aim of this study was to find out the rapid method for identification of P. aeruginosa and to detect the toxA, exoS and16SrRNAgenes by Polymerase Chain Reaction (PCR) technique. Other aim on the other hand, the DNA sequencing was performed for phylogenetic tree analysis of 16SrRNA gene in local pathogenic P. aeruginosa isolates in comparison with NCBI-Genbank global P. aeruginosa isolates and finally submission of the present isolates in NCBI-Genbank database. According to the detection of the 16S rRNA gene, the study revealed that 29 (58%) and 32 (64%) of P. aeruginosa out of 50 swabs obtained from each wound and burn areas were positive. whereas in addition, the result of this study showed that the toxA gene was detected in 77% of P. aeruginosa isolated from the wound and 51% of P. aeruginosa isolated from the burn. whereas, the exoS gene was detected in 69% of P. aeruginosa isolated from the wound and 49% P. aeruginosa isolated from the burn. BLAST analysis showed that the 16S rRNA gene shared more than 99% homology with the sequences of P. aeruginosa. Furthermore, the phylogenetic tree analysis of the 16S rRNA gene indicated that (PA-IQw and PA-IQb) the 16S rRNA gene shared higher homology with other four P. aeruginosa isolates available in the GenBank. The homology of the nucleotides was between 99.9% and 100%.

Oestrus ovis larvae 142 were collected from the 133 heads of sheep slaughtered at the Mosul abattoir in Nineveh governorate during March-May 2014. In This study, the weight and dimensions Oestrus ovis larvae and pupae were measured and there was a significant difference between larvae of Oestrus ovis. Forty five of the third larval stage were rearing and them pupated until emergence of the adult stage. Sixteen larvae were emerged to adult (35.6%). (4.4%) larvae did not pupariation and 60% were not reached to adult. The puparation period taking (24-30 hours) and the pupal stage taking (23-28) days the average longevity of adult flies was 10 days. This study is regarded as the first one showing that all flies were similar in their external shape and so all were belonging to Oestrus ovis causing myiasis in sheep.

Canine faeces are an important source of pathogens for the pet population, for dog owners and for the community in general. A total of 100 faecal samples taken from dogs, were examined for helminth eggs. 80 % of dogs examined are parasitized. Toxocara canis and Ancylostoma caninum were the most commonly observed parasites. T. canis was observed with a prevalence of 68 % in the El Kala region, while in the region of Guelma, A. caninum were predominant with a rate of 71%. Dipylidium caninum and Trichuris were present but with low proportions especially in the region of Guelma. The climatic conditions seem to play a role in the excretion of helminth eggs, while the age plays a primordial role in particular for T. canis as well as for A. caninum. The absence of conscience of the owners of dogs and the lack of participation of the veterinarian role increase the risk of the parasitism of these animals and consequently for the public health in particular our children in the Northeast of Algeria.

Acute Anaplasma ovis infections can cause severe clinical symptoms and might lead to significant economic losses in small ruminant flocks. However, little information has been provided related the prevalence of anaplasmosis in Angora goats. The study was designed to investigate the prevalence of Anaplasma ovis serologically (cELISA) and microscopically (Giemsa stained blood smears) among Angora goats from Duhok districts of the northern part of Iraq. A total of 92 blood samples were randomly collected from three localities of Duhok city; Zakho, Batel and Sumil during the study period from April to October 2009. The infection rate of A. ovis was 38.04% by Giemsa stained blood smear and 66.3% by cELISA. The prevalence of A. ovis in female goats was higher than that in males, but statistically not significant difference (P>0.05) by using both methods. The prevalence was also significantly higher (P<0.05) in goats more than three years old than in younger ones. The highest prevalence of A. ovis was found in Zakho, whereas the lowest was reported in Sumail. Results of hematological parameters indicated microcytic hypochromic type of anemia.It is concluded that A. ovis can infected Angora goats in district Duhok, Kurdistan region, Iraq and this might be due to high distribution of the disease and its transmitters which were lead to substantial effect followed by high mortalities

In the present study, forty donkeys of different ages and sexes at Giza Zoo, Egypt were investigated between October 2015 and September 2016 for the presence of hydatidosis disease. Hydatid cysts were detected in the livers of 10% of the examined donkeys and these cysts had a fertility rate 100%. Female donkeys were infected with cysts more than males and all infected donkeys were old aged with no cases of infection were detected in young or adult donkeys. Using molecular tools, the DNA extracted from cysts that had been isolated was subjected to PCR amplification, using synthesized oligonucleotide primers, and these were constructed to target the 299 bp within the (ND2) gene, which is considered to be specific for the Echinococcus equinus genotype. The sequenced PCR products showed homology to E.equinus (G4 or horse strain genotype). These results can be used in future to pursue the epidemiological status of the causative strain of hydatidosis in equines at the study area.

This study involved the detection of vermicules of Babesia spp in the hemolymph of Boophilus microplus adult females naturally fed on cattle after their remaining a live for 5 to 8 days under laboratory conditions and the detection of some developmental stages (schizonts, rupture of schizonts, small dark collar bodies and migration of vermicules from the hemolymph to different tissues of tick). Both vermicules of B. bovis and B. bigemina were diagnosed. The vermivules of B. bovis appeared as croissant or club-shaped bodies with a broad anterior ending and pointed posterior one and having a central nucleus and a vacuole in the anterior end with a curved or semi curved tail. The vermicules of B. bigemina had a croissant or club –shaped bodies with a lesser width in their anterior end than in B. bovis with no vacuole and with a straight tail. The average length of B. bovis was 13.92 ±1.34 µ with a range of 11.8-15.8µ and average width of 3.23±0.44 µ with a range of 2.7-4µ. The average length of B. bigemina was 11.39±1.12µ with a range of 9.5-13µ and average width of 2.2±0.51µ with a range of 1.5-3µ. The results of current study revealed that their was a direct and proportional relationship between the parasitemia of B. bovis and B. bigemina in cattle blood smears and the number of vermicules in the hemolymph of female of Boophilus microplus. No significant differences were noticed between (number and percentage of Boophilus microplus females) infected with vermicules of Babesia spp at different aged cattle.

Ticks infestation is the major problem of cattle and buffalo of Pakistan. Tick acts as vectors of many viral, protozoal and bacterial diseases and Crimean-Congo Haemorrhagic Fever (CCHF) is one of the most lethal in that list. During the last sixteen years, many sporadic outbreaks of CCHF in Pakistan has been reported with 24 percent case fatalities. In Punjab and Sind provinces mass tick control campaigns have been started to control the tick’s population and spread of zoonotic diseases through tick’s. In these tick control campaigns deltamethrin and ivermectin are used extensively. We highlighted that how extensive use of deltamethrin and ivermectin can adversely affect the environment and possible alternative methods for tick control. Extensive use of deltamethrin can damage the kidneys of insect eating birds and disturb the life cycle of many aquatic organisms if deltamethrin solution is mixed with water of streams. Widespread ivermectin use in domestic animals poses some serious threats to dung beetles and other coprophagic insects as almost 60-80 percent of total dose comes in feces without any metabolism in the body of animal. Decrease in dung beetles can result in decreased dung degradation.

Theileriosis is parasitic infection causes by obligate intracellular protozoa of the genus Theileria. T. lestoquardi is the most virulent species in sheep and goats which causes a severe disease with a high morbidity and mortality rate. In this study the phylogenetic relationships between two local isolate of T. lestoquardi and nine T. lestoquardi global isolates as well as Babesia ovis out-group isolate were analyzed using the 18S rRNA gene sequence. The multiple sequence alignment analysis and neighbor joining phylogenetic tree analysis were performed by using ClustalW multiple sequence alignment online based analysis of 1098bp 18S rRNA gene was amplified by polymerase chain reaction. Phylogenetic analysis results of these gene sequences revealed that T. lestoquardi local isolates were closely related to T. lestoquardi Iran isolate (JQ917458.1) and two Iraq Kurdistan isolates (KC778786.1 and KC778785.1) more than other countries. This study represents the first report on the use of molecular phylogeny to classify T. lestoquardi obtained in Middle Region of Iraq.

Toxoplasma gondii is an intracellular parasite that can cause significant morbidity in human beings and animals. Up to our knowledge no data is known of genetic diversity of T. gondii in sheep in Iraq. This study aim to detect the strains (genotypes) of T. gondii isolates from sheep in Wasit province, east of Iraq. A total of 315 samples (blood 300 and placenta's tissue 15) were collected from aborted ewes, which initially had been examined serologically by LAT, then further tested by RT-PCR through B1 gene amplification to confirm the infection with T. gondii. After that, the positive DNA samples were assayed for genetic characterization depending upon nested PCR- RFLP of SAG2 gene. Out of 315 examined samples, 10 were confirmed positive T. gondii DNA. The genotyping assay of them revealed that 60% (6/10), 30% (3/10) and 10% (1/10) of examined isolates represent the genotypes of II, III and I respectively. The type II appeared as dominant in sheep in Wasit province, Iraq.

Blastocystis sp. is an enteric unicellular, anaerobic, protist that could be isolated from humans and many other farm and wild animals, in addition to rodents, reptiles and insects. This study aimed to characterize Blastocystis isolated from fecal samples of human, cattle and sheep using restriction fragment length polymorphism (RFLP) analysis. Pre-determined samples were selected from human, cattle and sheep that showed to be positive by polymerase chain reaction (PCR) targeting the small subunit ribosomal RNA gene (SSU ‑ rRNA) then examined by RFLP analysis using HinfI enzyme to determine the molecular patterns. The results of RFLP analysis revealed the presence of three different patterns of human isolates which were in difference with the other three patterns of cattle isolates. However, sheep isolates showed only one pattern. This study shows that RFLP analysis is a simple and rapid technique that could be used to characterize and differentiate Blastocystis sp. in humans and animals.

The aim of present study was to report spontaneous Encephalitozoon cuniculi (E. cuniculi) infection in rabbits and Encephalitozoon intestinalis (E. intestinalis) infection in cattle in Mosul city - Iraq. Fecal samples were collected randomly from 142 rabbits and 115 cattle during the period from June, 2012 to June, 2013. Thin smears were prepared from the fecal samples and stained with different fecal stains, as well as the indirect immunofluorescent antibody technique. Infected rabbits were necropsied and pathology of the infection was described. The result showed that microsporidiosis was detected in 41 (26.9%) rabbits and in 12 (10.4%) cattle. E. cuniculi spores were identified in 31 out of the 41 rabbits (73.2%) and E. intestinalis in 7 out of the 12 cattle (58.3%). Infected rabbits showed vasculitis, granulomatous encephalitis, chronic interstitial nephritis, granulomatous hepatitis, cholangitis, vasculitis and non – suppurative pneumonia, infiltration of mononuclear cells in most layers of the intestines, and hyperplasia of lymphoid tissues. E. cuniculi spores were seen in the liver, kidneys and lungs. This study considered the first one that report microsporidiosis (E. cuniculi, E. intestinalis) in Mosul city - Iraq.
