This study was conducted to investigate Anoplocephalidia Cestoda in sheep and goat and evaluate the 18s rRNA to genetically differentiate the genera of this family. Sixty sample tapeworms were collected from small intestines of 30 sheep and 30 goats from different slaughterhouses in Al-Najaf and Al-Qadisiyah provinces, during September, 2016 to February, 2017. Based on polymerase chain reaction (PCR) and 18s rRNA gene partial sequencing (18sGPS) methods used, tapeworm infection of sheep and goat’s intestines was 32.9% and 31.4%, respectively. The partial gene sequencing of the 18S rRNA gene showed two closely related isolates of M. benedeni which are aligned distinctly to an NCBI isolate of the same species from China. For T. giardia, the outcomes of the phylogenetic analysis unveiled three distinct local isolates which were similar to an NCBI database isolate from China. The current data ensure the importance of the molecular techniques in differentiating between Thysaniezia (Helictometra) giardi and Moniezia species that were identified for their presence in the small intestines of sheep and goats.

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.
