The antimicrobial resistance currently impedes and threatens the future of effective prevention and treatment of the continually expanding range of infections caused by bacteria. This study aimed to identify the bacterial causes the wound infection among animals and using the antibiotic/nanoparticles mixture as a new attempt for the treatment the wound infection induced in rats. For this purpose, 112 swabs wound infection cases in the different animal types (36 sheep, 21 goats, 12 cows, 4 horses, 8 dogs, 9 rabbits, 7 genies pigs and 15 rats) were studied in the for bacterial isolation. The Pseudomonas aeruginosa was tested for its sensitivity to the antibiotics and the nanoparticles (CoFe2O4 and NiFe2O4) in vitro by using the MIC method. Also the wound infection was induced in the rats and the effect of nanoparticles/antibiotics mixture were tested in vivo. The results showed that P. aeruginosa was the predominant bacterial type that the caused wound infection. The minimum inhibitor concentration of NiFe2O4 and CoFe2O4 nanoparticles were 32 µg /ml and 16 µg /ml respectively. A clear synergistic effect of antibiotic/ nanoparticles as antibacterial were noticed which appear as a decrease in MIC and increase of the inhibitory diameter zone. According to the result of Random Amplification of Polymorphic DNA test, the nanoparticles effects on genetic material of P. aeruginosa observed as an appearance/disappearance of bands, increase in thickness and clarity of the bands.

The herbal drugs have a protective effect for kidney function against chemical toxicity. 24 male rats divided into 4 groups and treated as following, control group administrated orally with 1ml/kg. B.W physiological solution (0.9%), One dose Carbon Tetrachloride (CCl4) 3 ml/kg. B.W, Silymarin 150 mg/kg. B.W and Silymarin150 mg/kg. B.W with CCl4 3 ml/kg. B.W for 30 days. Oxidative stress resulted by CCl4 caused increasing in Creatinine, Urea, total protein, Albumin, malondialdehyde (MDA) levels decreasing in Glutathione (GSH) and superoxide dismutase (SOD) levels in serum and congestion, degeneration and desquamation in kidney tissue. We concluded that Silymarin showed protective effect via increasing GSH, decreasing creatinine, Urea, total protein and MDA levels in serum and protect kidney tissue in rats.

The present study aimed to describe the genetic relationships of zoonotic characterization of Klebsiella pneumoniae isolated from Human urinary tract and beef. The study includes (50) urine samples from human and (50) beef samples. The isolation and identification of Klebsiella pneumonia were done by using enrichment culture method and Vitek 2, then confirmed by PCR technique based on 16S ribosomal RNA gene which designed in this study using NCBI-GenBank (LT599801.1) and DNA sequencing was done on some positive isolates. The results show that Klebsiella pneumoniae was isolated from Beef at 38(76%) And from human at 32(64%) by vitek2. The PCR technique was show highly sensitive and specific confirmative detection of Klebsiella Pneumonia isolates at Clarify DNA sequencing of a partial sequence of 16S ribosomal RNA gene was shown homology sequence identity highly with NCBI-Blast Klebsiella pneumoniae isolates. The phylogenetic analysis was show clear genetic similarity at (0.5 genetic change) between human and beef in Klebsiella pneumoniae isolates. The gene sequence deposited into NCBI-GenBank accession numbers (MF314450.1, MF314451.1, MF314452.1, MF314453.1). In conclusion, the study presents the first report in Iraq of genetic relationship among K. pneumoniae isolates from beef and humans. Therefore, it is essential to define the role of animals as an important source for the distribution of pathogen related to public health.

This study was conducted to investigate the possible protective role of (CoQ10) on reproductive dysfunction of male rats induced by sodium fluoride (NaF). thirty two rats were divided into four even groups and treated for 56 days as follows: the first group served as control (C) The second group (G1) received coenzyme Q10 at dose of 10 mg/Kg.B.W; while third group (G2) received 100ppmsodium fluoride in drinking water and fourth groups (G3) received NaF 100 ppm and CoQ10 10 mg/Kg.B.W for 56 days. The results showed that exposure of rats to NaF caused decrease in serum testosterone (T) and luteinizing hormones (LH) concentrations. Whereas Administration of CoQ10 caused an increase the concentrations of theses hormones in group G3 as compared with group G2. Testicular morphometric and histopathological alterations were observed in group G2 in the form of marked microvacuolation in the basal level of germinal cells, amyloid deposited within seminiferous tubules with disarrangement and depletion of germ cells. Whereas testicular histological alterations were improved in rats treated with CoQ10. In conclusion, the results of the present study showed that use of Co Q10 can alleviating the deleterious effects on male reproductive function following exposure to NaF, may be via improvement the testicular functions or other related endocrine glands.

This study was carried out to study the effect of adding different levels of the microalgae Spirulina spp. in fish laboratory of Animal Sciences Department, College of Agricultural Sciences of Sulaimani University, Sulaimani, Iraq. A total of 72 common carp fingerling weight 45±2 gm used to detect the effect of three different levels of the algae Spirulina spp. The control treatment T1 with 0%., T2 with 3 gm /kg diet and T3 with 5 gm Spirulina /kg diet. Each treatment in three replicates in which six fingerlings common carp were stocked in each aquarium. Results indicated no significant differences at PSpirulina) in T3 was higher significantly at PSpirulina was higher significantly at PSpirulina to common carp diets in different levels leads to significant differences in differential WBC counts, T3 with 5 gm Spirulina /kg diet was higher in WBC counts. Lymphocytes were higher in each of control and T3. Monocytes were higher in control, granulocytes in T2 with 3 gm Spirulina /kg diet. Adding of Spirulina affected significantly in cholesterol as compared to the control. Triglyceride was higher in control and T2. T3 with 5 gm Spirulina /kg diet leads to higher and lower significantly in HDL and LDL respectively. T1 and T3 were higher significantly in spleenosomatic index. Inclusion of S. platensis in fish diet as a feed additive or as a partial replacer of the expensive fishmeal imposes significant promotions in fish growth, coloration, reproduction and flesh quality.

The aim of this study was to investigate the ameliorative effect of Broccoli against lead acetate (PbA) hepatotoxicity by some physiological and histological indicators. The results showed that intraperitoneal (I.P.) injection by 12 mg/kg body weight of lead acetate once a week for 8 weeks led to an increase in the activity of Glutamate pyruvate transaminase (GPT), Glutamate oxaloacetate transaminase (GOT), Alkaline phosphatase (ALP), Acid phosphatase (ACP), Total serum protein (TP) and Total serum bilirubin (TSB). Liver's histological sections of lead acetate injected rats showed infiltration of inflammatory cells with sinusoid dilation, necrosis, and apoptosis of Kupffer cells. Broccoli has an ameliorative effect, that the physiological parameters and histological examination have been showed an improvement. In conclusion, lead acetate produces hepatic disorder and the potential use of Broccoli as a source of natural antioxidants or nutraceuticals protects against lead acetate hepatic toxicity.
