This study was performed in order to isolate lactobacilli from chicken droppings and to select strains with the most promising probiotic properties. Lactobacillus strains were isolated from a flock of healthy laying hens. The first selection criterion was the ability to inhibit the growth of Salmonella Enteritidis. Then the tolerance to low pH and bile salt, the ability to coaggregate with pathogenic...
Coagulase-positive staphylococci (CoPS) are opportunistic veterinary pathogens, of which Staphylococcus aureus, S. delphini and S. intermedius can be isolated from pigeons. The biochemical identification of S. delphini and S. intermedius isolates may be incorrect, because of their phenotypic similarity. The purpose of the present study was to isolate and identify CoPS from domestic and feral pigeons...
Staphylococcus aureus subsp. anaerobius is the etiological agent of the Morel’s disease in sheep and goats. The disease presents with subcutaneous abscesses, located mainly in the superficial lymph nodes. Forty-one isolates of S. aureus subsp. anaerobius were collected from two outbreaks of the Morel’s disease in Poland in years 2006–2008. Analysis of DNA SmaI digests by PFGE showed that 35 of 41...
The aim of this study was to determine the species distribution among 44 randomly selected clinical isolates (30 mecA-positive and 14 mecA-negative) of animal origin previously identified as Staphylococcus intermedius by phenotypic tests and species-specific PCR amplification of the 16S rRNA gene. For this purpose, we used a multiplex PCR for the detection of the nuc gene and restriction fragment...
A total of 221 SIG strains were isolated from clinical samples of canine origin submitted to the Diagnostic Laboratory of the Division of Bacteriology and Molecular Biology at the Warsaw University of Life Sciences in Warsaw during the period 2006-2010. The aim of the study was to investigate the frequency of prevalence of methicillin-resistant SIG strains and to determine the MIC values of cephalotin,...
