Plasmid Profiles of Virulent Rhodococcus equi Strains Isolated from Infected Foals in Poland
Rhodococcus equi is an important bacterial pathogen in foals up to 6 months old, widespread in horse farms all over the world. It was found that only virulent R. equi strains expressing 15-17 kDa virulence-associated protein (VapA) and having large virulence plasmid of 85-90 kb containing vapA gene are pathogenic for horses. To date, 12 plasmid types have been reported in VapA positive strains ...
متن کاملQuantitative aspects of fecal Rhodococcus (Corynebacterium) equi in foals.
Quantitative aspects of fecal Rhodococcus (Corynebacterium) equi in newborn foals for 12 weeks after birth were investigated on two horse breeding farms. R. equi was found in the feces of foals during week 1 of life. The greatest numbers of R. equi were present in the feces of foals during the first 8 weeks of their lives, which coincides with the age when foals are most liable to be exposed to...
متن کاملRhodococcus equi in CAPD-associated peritonitis treated with azithromycin.
A 74-year-old man presented with a 1-day history of abdominal pain and cloudy dialysis fluid. Fifty years previously he had had a left orchidectomy and an inguinal hernia repair had been performed because of an undescended testis. Five years later he was found to have a left hydronephrosis requiring nephrectomy. He had psoriasis and a mild polyarthropathy. Fifteen years before this presentation...
متن کاملMICs of oxazolidinones for Rhodococcus equi strains isolated from humans and animals.
Eperezolid and linezolid are representatives of a new class of orally active, synthetic antimicrobial agents. The in vitro activity values (MICs) of linezolid, eperezolid, and comparator antibiotics against 102 strains of Rhodococcus equi isolated from humans and animals were determined. Linezolid was more active than eperezolid against the strains tested; premafloxacin was the most active comp...
متن کاملPrevalence of the virulence-associated gene of Rhodococcus equi in isolates from infected foals.
The prevalence of the plasmid-encoded virulence-associated gene (vapA) of Rhodococcus equi, as determined by PCR, was found to be 98% in isolates from 154 foals with pneumonia, confirming the strong association of vapA with virulence. The vapA genes from 60 representative isolates were compared by digestion with the restriction endonuclease HinfI, and no evidence of sequence variation was detec...
