The aim of this study was to determines the prevalence of virulence gene hemolysin A (hly A) Escherichia coli and Staphylococcal enterotoxins (sea) in Staphylococcus aureus in raw milk buffaloes. In molecular laboratory, real-time polymerase chain reaction (RT-PCR) technique has been performed for 24 samples which have been taken randomly from Buffaloes milk, using primers of high specificity for Escherichia coli hlyA gene and Staphylococcus aureus Sea genes. The results showed different degrees of the studied genes activities. Four out of 24 samples represented S. aureus Sea gene (16.6%) whereas 16 out of 24 samples represented E. coli hlyA gene (66.6%). this study concluded that buffaloes milk might be a source of contamination with pathogenic bacteria of virulent genes which may have different levels of activities.

In July 2010 outbreak was occurred in wild goat in Barzan, Sherwin mizzen and Mergasur in Kurdistan Region- Iraq. There were over 2700 deaths (both young and adult) during the period of July 2010 to October 2011. Based on the clinical signs and post-mortem findings, the involvement of peste des petits ruminants virus (PPRV) was suspected. This was confirmed by Real Time PCR technique using TaqMan®probes for the detection of Peste des petits ruminants. The results of Real-Time PCR for the 9 sample taken from 9 Wild goat there are 6 sample positive and 3 sample negative and 76 sample from domestic ruminants (sheep and goat) 63 samples was negative for PPR. This result confirms the diagnosis domestic ruminants in the region are routinely vaccinated with an attenuated vaccine based on the ‘Nigeria/75/1’ strain of PPRV.
