OBJECTIVE To compare the minimum inhibitory concentration (MIC) of cephapirin and ceftiofur with MICs of their active metabolites (desacetylcephapirin and desfuroylceftiofur) for selected mastitis pathogens. SAMPLE 488 mastitis pathogen isolates from clinically and subclinically affected cows in commercial dairy herds in Wisconsin. PROCEDURES Agar dilution was used to determine MICs for Sta...

Over the past few decades, Streptococcus dysgalactiae subspecies equisimilis (SDSE) have been considered as weak pathogenicity compared with S. pyogenes (GAS). Some recent reports argue that SDSE may bring severe soft tissue infection as same as GAS. No reports have been tried to reveal the clinical characteristics and autopsy images of fulminant SDSE infection. In this case report, we aimed to...

Developing chimeric lysins with a wide lytic spectrum would be important for treating some infections caused by multiple pathogenic bacteria. In the present work, a novel chimeric lysin (Ply187N-V12C) was constructed by fusing the catalytic domain (Ply187N) of the bacteriophage lysin Ply187 with the cell binding domain (146-314aa, V12C) of the lysin PlyV12. The results showed that the chimeric ...

BACKGROUND The present investigation was an endeavor into the elucidation of the disease-causing pathogen of streptococcosis in Nile tilapia (Oreochromis niloticus) in Egypt affecting adult fish cultured and wild fish in the Nile river. Fish were obtained from commercial fishermen, collected as part of their routine fishing activities. The researchers observed the routine fishing process and se...
