Saudi Arabia. The seroprevalece was determined by NP-epitopes based competitive ELISA. The overall prevalence was 59.9%, goats had a significantly higher sero-prevalence of 75.3% compared to 59.4% obtained from sheep, whereas camels were seronegative. The prevalence of PPR w...

While MDA for NDV remained 2.1 log2 until 28th day of age, the Geometric mean titers (GMT) for H5 were increased from the 7th day of age using both antigens (RE-5 antigen) and (S75/Egy/2015 antigen). Generally, GMT post-challenge was...

During January-December 2013, in total 700 samples were collected from different species of non-vaccinated birds inhabiting diverse ecological zones of Pakistan. Altogether, 507 tissue and swab samples were screened for the presence of viral RNA by reverse transcriptase polymerase chain reaction (RT-PCR). Same samples were further pro...

It was also observed that animals in closed housing system were more affected as compared to open housed animals. When comparative efficacy of diagnostic tests was done then the results of RT-PCR was found significant (P>5), than complement fixation test.

Samples were obtained from non-vaccinated lambs and kids with the signs of enterotoxaemia. The isolates were initially identified by colony characteristics, Gram staining, biochemical tests and CFU/g. Clostridium perfringens was isolated from 43.45% of lambs and 50.59% of the kids. Obtained isolates were furthe...

The collected serum samples (n=56) were examined for detection of leptospiral antibodies using the Microscopic Agglutination Test (MAT), the gold standard serological test. The Chi-square and odds ratio analyses were employed to identify the important risk factors for leptospirosis in dairy farms. The study revealed that the seroprevalence of bovine leptospirosis at an individual animal and farm level was 39...

Additionally, the non-medicated, non-vaccinated chickens were the most economical to raise. Overall growth-promoting antibiotics did not interfere with the broiler’s immunity, altered total intestinal microflora counts, or improved feed efficiency. ...
