Streptococcus agalactiae is one of the most common pathogens leading to mastitis in dairy herds worldwide; consequently, the pathogen causes major economic losses for affected farmers. In this study, multilocus sequence typing (MLST), genotypic capsular typing by multiplex polymerase chain reaction (PCR), and virulence gene detection were performed to address the molecular epidemiology of 59 bo...
Staphylococcus (S.) aureus is recognised worldwide as an important pathogen causing contagious acute and chronic bovine mastitis. Chronic mastitis account for a significant part of all bovine cases and represent an important economic problem for dairy producers. Several properties (biofilm formation, intracellular survival, capsular expression and group agr) are thought to be associated with th...
Camels are the most valuable livestock species in the Horn of Africa and play a pivotal role in the nutritional sustainability for millions of people. Their health status is therefore of utmost importance for the people living in this region. Streptococcus agalactiae, a Group B Streptococcus (GBS), is an important camel pathogen. Here we present the first epidemiological study based on genetic ...
Klebsiella pneumoniae is not only a major hospital-acquired pathogen but also an important food-borne pathogen that can cause septicaemia, liver abscesses, and diarrhea in humans. The phenotypic and genotypic characteristics of K. pneumoniae in retail foods have not been thoroughly investigated in China. The objective of this study was to characterize K. pneumoniae isolates through biotyping, s...
In 1954 we (Price and Kneeland) described a mucoid form of Micrococcus pyogenes var. aureus (Staphylococcus aureus) which showed capsular swelling with homologous immune serum. This mucoid variant, designated RL-mucoid, was derived from the parent RL strain after passage through embryonated eggs with influenza virus. Attempts to reproduce this variation by passing RL through embryonated eggs on...
pasteurella multocida is considered to be an important cause of ovine pneumonia and results causes considerable economic losses in iran. ribotyping pcr (ribo-pcr) was used for investigating the diversity of ovine and caprine p.multocida. a total of 120 swab tonsil and nasal samples were obtained from sheep and goats. they were analyzed by biochemical tests and ribo-pcr 16s-23s ribosomal rna gen...
The incidence and transmission patterns of extended-spectrum-beta-lactamase (ESBL)-producing Klebsiella pneumoniae in patients admitted to the intensive care unit (ICU) of a university hospital were investigated over a 3-year period. K. pneumoniae isolates were characterized by antibiotic susceptibility, capsular serotyping, plasmid profiles, and pulsed-field gel electrophoresis (PFGE) of genom...
