Clinical isolates of bacteria from domestic cats in Grenada, and their anti-microbial susceptibility
Harry Hariharan, Erica Sylvester, Vanessa Matthew
Of a total of 57 consecutive clinical samples from domestic cats in Grenada, 23 were culture positive for aerobic bacteria. Of 23 isolates from these samples, 13 were Gram-negative bacteria, the majority (54%) being Escherichia coli from uninary tract infections and wounds/abscesses, followed by Pseudomonas aeruginosa. Of the 12 Gram-positive isolates, the majourity (75%) were staphylococci, originating from various infections. Among the less common isolates were, an Enterobacter cloacae strain associated with otitis externa, an Enterococcus faecalis strain associated with urinary tract infection, and a Streptococcus pneumoniae strain associated with upper respiratory infection. Antimicrobial resistance was least to enrofloxacin, the rate being 5.2%, followed by gentamicin (12%), chloramphenicol (14.2%), amoxicillin-clavulanic acid (15%), cephalothin (20%), and tetracycline (38.1%). All Gram-negaitve isolates were susceptible to enrofloxacin, and all Gran-positive to amoxicillin-clavulanic acid.
