isolations of aerobic bacteria from wild desert bighorn sheep (ovis canadensis nelsoni and o. c. mexicana) in arizona.nasal, pharyngeal, cervical and vaginal swab specimens were obtained from 74 desert bighorn sheep for the purpose of investigating the normal aerobic bacterial flora of wild sheep. a total of 281 isolates was obtained and identified by standard microbiologic tests. one hundred seven of these isolates were gram positive and included bacillus sp. (36%), staphylococcus epidermidis (8%), s. aureus (4%), corynebacterium sp. (diphtheroids, 4%), and streptococcus sp. (48%). gram negative isolates total ...19836887449
enteric bacterial growth rates in river water.enteric bacteria, including stocked strains of pathogenic species and organisms naturally present in the stream, were capable of growth in a chemostat with autoclaved river water taken 750 m below a sewage outfall. maximal specific growth rates for all organisms occurred at 30 c, whereas culture generation times ranged between 33.3 and 116 hr. of the six laboratory strains of enteric species used, escherichia coli and enterobacter aerogenes grew at generation times of 34.5 and 33.3 hr, respectiv ...19724561100
gram-negative, aerobic, enteric pathogens among intestinal microflora of wild turkey vultures (cathartes aura) in west central texas.the prevalence of gram-negative bacterial species in the intestines of 20 apparently healthy turkey vultures (cathartes aura) was determined. edwardsiella tarda, plesiomonas shigelloides, salmonella, and arizona hinshawii (salmonella arizonae) were each recovered from 15% of these birds. turkey vultures may be important reservoirs of these bacterial pathogens.19817032423
