متن کاملThe frequency of photosensitization in a dairy cattle herd infected by Leptospires
Leptospirosis is a bacterial zoonotic disease, which can induce hepatic lesions. Photosensitization (PS)maybe is the result of accumulation of photodynamic agents in unpigmented area of the skin exposed tosunlight which occurred due to hepatic lesions. An outbreak of leptospirosis was occurred in a dairy cattleherd complex with 760 dairy milking cows in March (1990). Totally, 412 cows (54.21%) ...

متن کاملPrevalence of Escherichia coli O157:H7 on dairy farms in Shiraz, Iran by immunomagnetic separation and multiplex PCR
To identify the reservoirs of shiga toxin-producing Escherichia coli O157, sensitive detection andisolation methods are necessary. The sensitivity of traditional culture methods can be improved significantlyby the inclusion of an immunoconcentration step, resulting in less false-negative results. In this study,enrichment procedure and immunomagnetic separation (IMS) were compared for use in con...
