Experimental infection with Treponema hyodysenteriae in guinea pigs.
Outbred and inbred (Hartley strain) guinea pigs (GP) were inoculated intragastrically with pathogenic and nonpathogenic Treponema hyodysenteriae. GP 3 to 16 weeks old received T. hyodysenteriae after a fasting period of 36 to 72 h. Infected GP with pathogenic T. hyodysenteriae developed a diarrheal and/or depressive condition, with mucus but not blood in the feces. Of 88 GP, 40 had gross lesion...
متن کاملSerological grouping of Treponema hyodysenteriae.
Two Australian isolates of Treponema hyodysenteriae which did not fit within the current serological grouping system for these bacteria were examined by agarose gel double immunodiffusion tests (AGDP). Isolate Vic1 was serologically unique, and we propose that it becomes the type organism for a new sixth serological group of T. hyodysenteriae (Group F). Isolate Q1 was unusual in that lipopolysa...
متن کاملIsolation of Treponema hyodysenteriae from wild rodents.
Rodents from swine-producing farms were examined for the presence of Treponema hyodysenteriae. Wild mice (n = 257) and rats (n = 41) were trapped on eight farms. Ceca were removed aseptically, and the contents and mucosal scrapings were cultured on selective medium (blood agar containing 400 micrograms of spectinomycin per ml). T. hyodysenteriae was detected in the cecal scrapings of four mice ...
متن کاملSusceptibility of inbred mouse strains to infection with Serpula (Treponema) hyodysenteriae.
Several inbred strains of mice were inoculated with Serpula (Treponema) hyodysenteriae B204 to determine susceptibility to infection. Challenge doses of 10(7) or 10(8) spirochetes induced cecal lesions in C3H/HeJ mice and other C3H strains of mice. However, more than a 100-fold difference existed between the dose required to induce lesions in 50% of the infected C3H/HeJ mice (8.3 x 10(7)) and t...
متن کاملSelective medium for isolation of Treponema hyodysenteriae.
Pure cultures of six pathogenic isolates of Treponema hyodysenteriae, the colonic mucosal scrapings of seven pigs with acute swine dysentery, and feces from seven unaffected pigs were diluted in phosphate-buffered saline and plated on Trypticase soy agar with 5% citrated bovine blood (TSA) and TSA with various levels of spectinomycin (TSA-S). The plates were incubated at 42 degrees C in a vente...
