in vitro characterization of field isolants of pasteurella multocida from georgia turkeys.field isolants of pasteurella multocida from fowl cholera outbreaks in georgia turkeys were characterized by three sets of criteria: differential biochemical reactions, in vitro drug sensitivity, and serology. of the 30 isolants studied, 28 exhibited identical biochemical patterns. these were similar to previously described patterns for turkey isolants of p. multocida. the two exceptions were isolants recovered from the same farm at different times. they differed only in ability to ferment arabi ...19751164320
fowl cholera in broilers.pasteurella multocida, the etiologic agent of fowl cholera, was isolated from six broiler flocks in georgia during summer 1988. the flocks ranged in age from 20 to 46 days, represented four companies, and spanned a distance of 50 miles. increased mortality and lameness were the clinical signs present in all affected flocks. bacterial isolation and agar gel precipitation for somatic antigen serotyping revealed that three of the cases were caused by serotype 1,3, two by serotype 3,4, and one by se ...19892619670
characteristics of fowl cholera outbreaks in turkeys in georgia in 1986.information was gathered from 64 cases of fowl cholera (fc) in turkey flocks through diagnostic case records, flock records, and telephone and mail surveys. forty-five cases came from flocks of commercial turkeys, of which 15 were presented twice, and four came from mature breeder flocks. the prevalence of fc was 18.0% of commercial flocks and 14.7% of breeder flocks at risk. the average age at first diagnosis of fc was 90 days in commercial turkey flocks and 32 weeks 5 days in breeder flocks. a ...19892751551
diagnostic summary of 1986 turkey, broiler breeder, and layer necropsy cases at the university of georgia.turkey, broiler breeder, and layer cases submitted for necropsy in 1986 to the university of georgia were categorized by diagnosis, grouped by clinical features, season, age, and presenting history, and evaluated for statistically significant patterns. the most commonly diagnosed diseases were: fowl cholera in turkeys, 64 cases (34.4% of cases; 26.2% of diagnoses); staphylococcal arthritis/synovitis (sa/s) in broiler breeders, 35 cases (20.7%; 17.7%); and osteomalacia in layers, 17 cases (21.0%; ...19883143349
disease prevalence in georgia turkey flocks in 1986.disease prevalence in turkeys was estimated by totaling the flock size of necropsy cases submitted to the university of georgia in 1986 for each disease reported and comparing it with the population at risk. fowl cholera was the most prevalent disease in both commercial tom flocks (18.0%) and breeder hen flocks (14.7%). prevalence of colibacillosis was 15.9% in commercial tom flocks, and prevalence of aspergillosis was 8.5% in commercial tom and 4.9% in breeder hen flocks.19883143350
estimate of economic impact of fowl cholera in turkeys in georgia in 1986.information gathered from cases of fowl cholera (fc) in commercial turkey flocks through case records, flock records, and telephone and mail surveys was used to estimate disease costs. the cost to the georgia commercial turkey industry in 1986 from preventive measures, treatment of outbreaks, and production losses from the disease was estimated at $634,545. the cost of fc per kg of live production was estimated to be $0.015.19883202770
