the aim of this study was to investigate the effect of Pit-1 polymorphism on the some blood parameters in dairy local Iraqi cattle, blood samples were collected from (120) healthy dairy cow breeds aged between (4-6 years), in peak stage (40-120) days of lactation, during period of time beginning from September 2017 till January 2018, in the northeast of rural areas in Karbala province. Amplification Refractory Mutation System (ARMS-PCR) techniques was used to detect Pit-1 polymorphism and to classified the genotyping in to three groups; wild group AA, recessive group BB and heterozygosity group AB.The frequencies of genotypes were recorded as 0.06 for AA, 0.70 for AB and 0.24 for BB on the other handthe frequencies of allele were recorded as 0.41 for Pit-1(A) and 0.59 – Pit-1(B).The current study showed no significant decrease (p, >0.05) in the RBC, Hb&MCHC in AB&BB genotype groups compare with AAgenotype group, also the PCV % was no significant difference in all groups. The conclusion our study showed that not found effects of pit 1 polymorphism on the some blood parameter in dairy cow.

Mycoplasma gallisepticum (M. gallisepticum) is a bacterium that causes chronic respiratory disease (CRD) and infectious sinusitis (IS) in chickens and turkeys. Therefore, rapid and immediate diagnosis or regular detection of Mycoplasma may be of great help to early detection. 120 chicken layers, Within Karbala city, were carried out during their laying period on breeding flocks. The study proposed a promising method for isolation of M. gallisepticum, 120 tracheal swabs and blood samples from chickens in different dairy farms were used to analyze M. gallisepticum utility of PCR and culture. Compared with ELISA anti-IgG M. gallisepticum, the clinical specificity of PCR detection is 89.66%, the sensitivity is 86.36%, and the kappa coefficient is 0.817. Compared with the culture method, the specificity is 100%, the specificity is 45%, and the kappa coefficient is 0.543. Demonstrate the method's effectiveness and applicability as a standard method for mycoplasmas field diagnosis.

The lack of dedicated RV treatment makes early detection and effective vaccines important to prevent increased mortality and morbidity, as they can only be treated with fluid and electrolyte replacement. The study's goal was to assess the specificity and sensitivity of Reverse transcriptase PCR and Rapid immunochromatography techniques for Rotavirus detection. Between November 2020 and June 2021, 320 stool samples from children under the age of five were obtained at Babylon Teaching Hospital. Primary detection of Rotavirus contamination has executed the use of immunochromatography test (rapid test) LumiQuickAdeno-RotaVirus Antigen Comb takes a look at(Netherlands) and opposite transcriptase PCR in the detection of Rotavirus infection by means of using structural gene (vp4), the results discovered that Rotavirus became detected at a high rate in male stool samples (67.5%) rather than a girl (32.5%). December and Januarywere observed the biggest number of cases, with (46.6%) and (28.3%), respectively.The rural area had the highest rate of Rotavirus infection (56.6%), compared to (43.4%) in the urban area.The RT-PCR assay's excellent overall performance was also considered in its capability to identify Rotavirus RNA in 84 of 320 children's prevalence (26.25%).

CTLA4 is a regulator gene for T cells and relates to autoimmune diseases. By using a case-control method, CTLA4 functional single-nucleotide polymorphisms for potential associations with Type 1 diabetes mellitus in an Iraqi children's population. ARMS-PCR method is used for genotyping +49AG (rs231775) variations in 60 obese children and 60 ethnically matched controls; all measured subjects were (fasting glucose, fasting insulin, and HbA1c). The glucose oxidase method is used to determine plasma glucose levels. The amounts of insulin in the blood were determined using a radioimmunoassay (RIA); Insulin resistance was measured using the HOMA-IR index. A HOMA-IR cut-off level of 2.5 was acceptable. There was no significant difference in allele and genotype frequencies between the groups, according to CTLA4 +49AG analyses. In conclusion, AA cases had a high frequency of A/A genotype than healthy participants but lower rates of A/G and G/G genotypes.
