Comparison of Virulence Gene Profiles of Escherichia coli Strains Isolated from Healthy and Diarrheic Swine
TLDR
A combination of uni- and multiplex PCR assays targeting 58 virulence genes (VGs) associated with Escherichia coli strains causing intestinal and extraintestinal disease in humans and other mammals was used to analyze the VG repertoire of 23 commensal and clinical porcine enterotoxigenic E. coli strains. Expand
Abrupt emergence of a single dominant multidrug-resistant strain of Escherichia coli.
TLDR
Most current fluoroquinolone-resistant E. coli clinical isolates represent a highly clonal subgroup that likely originated from a single rapidly expanded and disseminated ST131 strain, which expanded abruptly after 2000. Expand
Serpulina pilosicoli, waterbirds and water: potential sources of infection for humans and other animals.
TLDR
Multilocus enzyme electrophoresis analysis of the isolates showed that they were genetically diverse, and none had identical electrophoretic profiles as those previously obtained from human beings, dogs, pigs and other avian species. Expand
Isolation of Serpulina pilosicoli from Rectal Biopsy Specimens Showing Evidence of Intestinal Spirochetosis
TLDR
The association between seeing spirochetes in biopsy specimens and isolating S. pilosicoli was statistically significant, clearly indicating that thisSpirochete is the agent of IS. Expand
Experimental infection of newly weaned pigs with human and porcine strains of Serpulina pilosicoli
TLDR
The role of S. pilosicoli in the etiology of PIS is confirmed and evidence that S. Pilosicol strains of human origin have pathogenic potential in an animal model is provided. Expand
Recognition of two new species of intestinal spirochetes: Serpulina intermedia sp. nov. and Serpulina murdochii sp. nov.
TLDR
On the basis of DNA-DNA hybridization data, nine intestinal spirochete strains were grouped into five genospecies and new Serpulina species were found, for which the names SerPulina intermedia sp. Expand
Characterization of Treponema phagedenis-Like Spirochetes Isolated from Papillomatous Digital Dermatitis Lesions in Dairy Cattle
TLDR
Both antibody and lymphocyte blastogenic responses were reduced in convalescent dairy cattle, suggesting the immune response to these spirochetes has short duration and genetic and antigenic diversity among T. phagedenis-like treponemes is demonstrated. Expand
Population genetic analysis of Serpulina pilosicoli and its molecular epidemiology in villages in the eastern Highlands of Papua New Guinea.
TLDR
PFGE analysis using the enzymes M/ul and Sa/l divided 157 of the isolates into 99 PFGE types, demonstrating the existence of considerable strain diversity in a geographically restricted area and PFGE was more discriminatory for strain typing than was MLEE. Expand
Serpulina pilosicoli sp. nov., the agent of porcine intestinal spirochetosis.
TLDR
DNA-DNA relative reassociation experiments in which the S1 nuclease method was used revealed that intestinal spirochete strain P43/6/78T was related to, but was genetically distinct from, both S. hyodysenteriae B78T and S. innocens B256T, and it is proposed that strain P 43/ 6/78 should be designated as the type strain of a new species, Serpulina pilosicoli. Expand
Fluorescence in situ hybridization analysis of hindgut bacteria associated with the development of equine laminitis.
TLDR
Of the microorganisms specifically targeted, streptococci of the Streptococcus bovis/equinus complex were the only bacteria that consistently proliferated in both caecal fluid and faeces immediately before the onset of histological signs of laminitis. Expand
