AEROBIC BACTERIAL ISOLATIONS FROM HARBOR SEALS (PHOCA VITULINA) STRANDED IN WASHINGTON: 1992–2003

摘要: Bacterial cultures collected over 12 yr from stranded harbor seal (Phoca vitulina) pups and weanlings located in the North Puget Sound San Juan Islands region of Washington were analyzed retrospectively to determine most common pathogenic isolates describe their antimicrobial resistance patterns. Culture attempts (n = 58) wounds, umbilici, ears, conjunctiva, nares, oral lesions, feces yielded 134 that represented 17 genera. The majority Gram-negative 87; 65%) tested susceptible amikacin 76; 99%) gentamicin 97%) least ampicillin 26%). Of Gram-positive 29), all amoxicillin/clavulanic acid. frequent Escherichia coli (17%), beta-hemolytic Streptococcus spp. (15%), Enterococcus (11%), Pseudomonas aeruginosa with four exhibiting more than 50% antimicrobials tested. variety organisms isolated, variation either or predominance, multiple drug patterns observed suggest when treating seals, culture sensitivity testing are warranted antibiotic therapy should be based on results.
