Fifty serotyped isolates each of Pasteurella multocida and Pasteurella haemolytica were tested on the API 20E strip (Analytab Products, Plainview, N.Y.), the Oxi/Ferm tube (Roche Diagnostics, Nutley, N.J.), and the Minitek system (BBL Microbiology Systems, Cockeysville, Md.). None of the rapid test systems reliable identified these organisms. With the API system, discrepancies between expected ...

The API 20E and Oxi/Ferm systems were tested in parallel to identify nonfermentative bacteria and oxidase-positive fermentative bacteria. Test strains consisted of consecutive clinical isolates, with stock cultures used to supplement those species infrequently recovered. The two microsystems, as well as tubes of triple sugar iron, motility, cetrimide, and oxidative glucose media, were inoculate...

A 40-year-old female presented with purulent exudate through the left auditive duct and pain in the left ear region, which intensified during mastication. After collection of the pus from the left ear lesion, amoxicillin-clavulanic acid for seven days was prescribed for a presumed diagnosis of acute otitis. Four days later, the pus culture grew V. fluvialis which is further identified by API 20...

We identified 6 sucrose-fermenting Vibrio vulnificus strains and examined their virulence characteristics. They were all encapsulated, motile, capable of producing toxins and utilizing transferrin-bound iron, cytotoxic to cultured cells, and virulent enough to kill mice. They could be definitely identified only by genetic identification methods such as PCR, and not by conventional culture-based...

Six conventional biochemical tests were combined to produce an identification scheme. These tests included decarboxylation of lysine and ornithine, fermentation of glucose and cellobiose, indole production and urease production. Three hundred antibiotic resistant coliforms from urine specimens were tested by this scheme and also by the API 20E for comparison. Two hundred and seventy nine (93%) ...

Bacterial isolates from common carp (Cyprinus carpio L.) and rainbow trout (Oncorhynchus mykiss) were identified by the API 20E system (bioMérieux). Twenty one isolates were identified as Shewanella putrefaciens. These isolates were tested for selected biochemical and cultural characteristics. Pathogenicity of two isolates (Pt38 and K116) for freshwater fish was assayed. Biochemical characteris...
