Prevalence of Rhodocococcus equi infection in foals

摘要

One hundred thirty one samples (nasal, faecal, soil, tissue from dead foal) were tested for presence of Rhodococcus equi. These samples included 58 nasal swabs including 45 from foals with respiratory problem and 13 from in contact apparently healthyfoals. Faecal samples were 54 including 41 from foals with respiratory problem and 13 from in contact apparently healthy foals. Faecal and nasal samples were from same foals, soil samples from infected premises were 15, besides tissues from foals (4) which died due to respiratory problems. Fourteen isolates of Rhodococcus equi were obtained from foals with respiratory problems, which were subjected to in vitro antibiotic sensitivity testing to 17 antimicrobial agents which were amoxycillin, gentamycin,ampicillin, triniethoprim, chloramphenicol, sulphadiazine, cloxacin, oxytetracycline, amikacin, streptomycin, cotrimoxazole, cephalexin, kanamycin erythromycin, ciprofloxacin, neomycin and rifampicin. All the isolates were found sensitive to chloramphenicol, erythromycin, oxytetracycline, ciprofloxacin, neomycin and rifampicin.
