Bacillus thuringiensis is a ubiquitous a gram-positive, anaerobic, spore-forming bacterium, produces various proteins (toxins) during the stationary and vegetative phase of its growth cycle. Some of these proteins belonging to this group showed weak similarities to ß-barrel pore-forming toxic proteins, such as the cytotoxins of Pseudomonas aeruginosa, the epsilon toxin of Clostridium perfringens, alpha-toxin of Clostridium septicum. In the present study, the intoxication effects of Cry51Aa1 protein produced by B.thuringiensis F14-1 strain was evaluated in vivo, in order to investigate the ability of activated Cry51Aa1 to make a change in size or functions of zebrafish cardiovascular system and induces toxicity in adult zebrafish. Using in vivo imaging we observed that Cry51Aa1 has no scientific effect on cardiac function and development of zebra fish embryo or have toxic effect on adult in spite of use high concentration, so it is safe to use and a potentially effective agent in breast cancer therapy.

Mosquitoes apply very important impact on people life, and their control, day by day, is getting harder and harder. This difficulty comes from different issues such as insecticide resistance. The gut microbiome (GM) in different animals has been discovered to add principle influence on the gastrointestinal tract physiology. For example, GM participates in degradation of some poisonus chemicals into safer molecules that could be handled by the animal host. Eukaryotic cytochrome P450 has been detected to inseret some degradation processes in other animal models such as zebra fish. However, these effects are not yet known in mosquitos. In order to stand on these problems and find if the prokaryotic P450 is involved, this study had been done to find out if the GM has any role in developing such resistance in mosquitos. Larvae were used in this experiment which exposed to benzothiozole (BZT) to trigger the hypothetical role of prokaryotic P450. By using polymerase chain reaction (PCR), the result indicates that the bacterial P450 was initiated and might be involved in the BZT exposure handling

Cross-sectional study carried in areas surrounding Baghdad province (Dora , Nahrawan, Tajy and Abu Graib )respectively. During June -December 2016, for detection of cattle Babesiosis. One hundred fifty (150) clinically healthy local cattle breeds of different ages, and from both sex were examined by routine blood smear examination, molecular detection of Babesiosis by Conventional polymerase chain reaction PCR and by ELISA test. Results revealed that the infective species of Babesia during this study were B.bovis and B.bigemina that had detected in 14 cases ( 9.33%) by traditional blood smear examination, compared with 15 cases ( 10% )with Babesia bovis by conventional PCR technique and 100 cases (66.6%)with Babesia bigemina were detected by using ELISA technique .It has been concluded that infection with Babesia.bovis and Babesia bigemina were more prominent and no other species were detected

In this study the seroprevalence of active toxoplasmosis represented by T. gondii IgM in angora goats was detected in Zakho and Semel districts of Duhok provinceIraq for the first time. T. gondii antibodies were detected at the laboratory of college of Veterinary Medicine of Duhok University from April 2009 to May 2010. Ninety two (92) serum samples were collected from clinically healthy adults’ angora goats (54 and 38 were obtained from Semel and Zakho, respectively). Indirect Enzyme Linked Immunosorbent Assay was applied and the overall infection rate was %13.04. Results show that the infection rate was different between the two regions with a higher rate recorded in Zakho. Female and older animals were affected with higher infection rates than males and younger animals. It can be concluded that toxoplasmosis is an active infection among angora goats of Duhok province, therefore145 for more biosecurity measures and to minimize the zoonotic impact of the disease all animals must be screened periodically.

Lespedeza cuneata (poorman’s lucerne; sericea lespedeza), a tannin-rich perennial legume, was offered as hay to dry Merino ewes in a confined feeding experiment to evaluate the effect on the level of gastrointestinal parasite infection in sheep. Medicago sativa (a low tannin containing perennial legume) was used as the control treatment. Parameters faecal egg count (FEC), FAMACHA© scores and rectal temperatures were used. FECs were substantially lower (p = 0.05) in the Lespedeza group after 35 days, together with a trend of higher rectal temperatures, compared with the Medicago group. Although non-significant (p > 0.05), the higher rectal temperatures suggested a lower level of anaemia in the sheep on the Lespedeza ration and, therefore, a lower parasite-worm burden. However, FAMACHA© scores showed no significant (p > 0.05) differences between treatments despite the differences in FEC that were recorded, indicating that host homeostasis was possibly mediated by improved nutrition as a result of the high protein content of both experimental diets.

Enterotoxaemia (pulpy kidney) is a common bacterial disease of sheep caused by Clostridium perfringens type D epsilon toxin. It has mortality rates of up to 30% in non-vaccinated animals. Current vaccines from whole cell cultures are expensive to manufacture and can induce local inflammatory responses in sheep. They usually have reduced immunogenicity because of the difficulty of standardising the inactivation step in vaccine manufacturing. In the current study, we evaluated the safety and potency of a recombinant plant-made epsilon toxoid protein (r-Etox) as an affordable and safer alternative vaccine for developing countries. Results of injection site reactions, rectal temperature and toxin neutralisation test in single and prime– boost inoculations of mice, guinea pigs and sheep suggest that the product is not toxic to animals and could protect sheep against enterotoxaemia.
