Campylobacter prevalence in lactating dairy cows in the United States.
The authors conclude that Campylobacter prevalence in lactating dairy cows in the United States is low, there is no difference in prevalence on the basis of geographical location, the predominant species is C. jejuni, and that the majority of these isolates are sensitive to antibiotics. Expand
Genotypic variation among arcobacter isolates from a farrow-to-finish swine facility.
The level of genotypic variation revealed by PFGE suggested that pigs in this farrow-to-finish operation were colonized by multiple Arcobacter parent genotypes that may have undergone genomic rearrangement, common to members of Campylobacteraceae, during successive passages through the animals.

Prevalence of antimicrobial resistance in Salmonellae isolated from market-age swine.
Results of this study suggest that a correlation exists between the somatic serogroup or serovar of a Salmonella isolate and its antimicrobial resistance status, which is specific to the antibiotic of interest and the source of the isolate (lymph node versus cecal contents). Expand
In Vitro Cultivation of a Zoonotic Babesia sp. Isolated from Eastern Cottontail Rabbits (Sylvilagus floridanus) on Nantucket Island, Massachusetts
ABSTRACT A Babesia sp. found in eastern cottontail rabbits (Sylvilagus floridanus) on Nantucket Island, Massachusetts, is the same organism that caused human babesiosis in Missouri and Kentucky, onExpand
Further characterization of Campylobacter isolated from U.S. dairy cows.
It is concluded that ribotyping is not as discriminatory as PCR for speciation, and that a phenotypic trait such as antimicrobial resistance cannot always be predicted within the same genotype. Expand
The use of flow cytometry to detect expression of subunits encoded by 11 Salmonella enterica serotype Typhimurium fimbrial operons
In vivo growth conditions drastically alter the repertoire of fimbrial antigens expressed in S. Typhimurium, and it is shown that FimA was the only fimbrian antigen expressed by S. Typhooni after static growth in Luria–Bertani broth. Expand
Prevalence of Campylobacter spp isolated from the intestinal tract of pigs raised in an integrated swine production system.
Analysis of results of this study suggests that a relatively high prevalence of C jejuni may be found in pigs raised on specific farms, similar to that found in other integrated swine operation in Texas. Expand
In vitro cultivation of a newly recognized Babesia sp. in dogs in North Carolina.
A novel large Babesia sp. from an infected dog was cultivated in vitro by microaerophilous stationary phase culture methodology. A primary culture initiated in enriched RPMI-1640 medium supplementedExpand
Campylobacter coli Pulsed Field Gel Electrophoresis Genotypic Diversity Among Sows and Piglets in a Farrowing Barn
Results indicate that a high number of Campylobacter genotypes may coexist in related pigs from a single housing facility. Expand
Some specific staining reactions of potassium ferricyanide in cells of guinea pig testes.
Guinea pig testes were processed for electron microscopy by prefixing in phosphate-buffered aldehyde and postfixing in 1% OsO 4 plus 0.05 M potassium ferricyanide [(K 3 Fe(CN) 6 )]. The K 3 Fe(CN) 6Expand
