culture and serologic survey for mycobacterium avium subsp. paratuberculosis infection among southeastern white-tailed deer (odocoileus virginianus).from july 1998 through october 2002, radiometric culture (ileocecal lymph node, mesenteric lymph node, and feces) and serologic testing by enzyme-linked immunosorbent assay (elisa) were used to survey white-tailed deer (odocoilens virgianus) from the soutlheastern united states for infection by mycobacterium avium subsp. paratuberculosis (mptb), the causative agent of paratuberculosis (johne's disease). mycobacterium avium subsp. paratuberculosis was isolated from the ileocecal lymph node of one ...200415362831
johne's disease in a free-ranging white-tailed deer from virginia and subsequent surveillance for mycobacterium avium subspecies paratuberculosis.johne's disease (paratuberculosis) was diagnosed in a 2-yr-old, male, free-ranging white-tailed deer (odocoileus virginianus) from fauquier county, virginia, usa, based on histopathology and culture for mycobacterium avium subspecies paratuberculosis. clinical and pathologic findings included emaciation; loss of body fat; chronic diarrhea; severe, chronic, diffuse granulomatous colitis with intrahistiocytic acid-fast bacilli; moderate, chronic granulomatous lymphadenitis with intrahistiocytic ac ...200919204350
persistence of mycobacterium avium subspecies paratuberculosis in endangered florida key deer and key deer habitat.mycobacterium avium subsp. paratuberculosis (map) was first reported in the endangered key deer (odocoileus virginianus clavium) in 1996 on big pine key, florida, usa. by 2008, eight additional map-positive key deer had been identified on big pine key and the nearby newfound harbor keys. this study was conducted to determine if map was still present in key deer and whether natural or man-made freshwater sources were contaminated with map. between november 2009 and september 2012, map was isolate ...201424506424
distribution of mycobacterium avium subspecies paratuberculosis in the lower florida keys.johne's disease, a fatal and contagious gastrointestinal infection caused by mycobacterium avium subsp. paratuberculosis (map), was first diagnosed in an endangered florida key deer (odocoileus virginianus clavium) in 1996 and later in six additional key deer deaths from 1998 to 2004. we investigated the geographic distribution of map in the lower florida keys from february 2005 through may 2006 via collection of blood and fecal pellets from 51 live-captured deer, collection of 550 fecal samples ...200818689642
paratuberculosis in key deer (odocoileus virginianus clavium).paratuberculosis was diagnosed in an endangered key deer (odocoileus virginianus clavium) in november 1996. between 10 april 1997 and 28 september 2000, the key deer population was monitored for infection with mycobacterium avium subsp. paratuberculosis by necropsy of available carcasses (n = 170), fecal cultures, and serology. one additional clinically affected key deer was discovered in july 1998, and m. avium subsp. paratuberculosis was cultured from the feces of one live, asymptomatic deer. ...200212528439
morbidity and mortality factors in key deer (odocoileus virginianus clavium).the population health of endangered key deer (odocoileus virginianus clavium) was monitored from 10 february 1986 to 28 september 2000 by necropsy of animals that were killed by vehicles, euthanized because of terminal injuries or disease conditions, or found dead. the predominant mortality factor during the period was collision with motor vehicles; however, several infectious diseases were diagnosed, including infections with arcanobacterium pyogenes, haemonchus contortus, salmonella spp., and ...200212528433
nested pcr on blood and milk for the detection of mycobacterium avium subsp paratuberculosis dna in clinical and subclinical bovine paratuberculosis.to determine the potential of pcr on blood and milk to detect cattle infected with mycobacterium avium subsp paratuberculosis.200415359966
use of an enzyme-linked immunosorbent assay to estimate prevalence of paratuberculosis in cattle of florida.a survey was conducted from 1986 through 1987, for which an elisa was used to obtain information on the prevalence of mycobacterium paratuberculosis infection in cattle of florida. results revealed prevalence of 8.6% in beef cattle and 17.1% in dairy cattle. in beef and dairy cattle, prevalence increased with increasing herd size. it was concluded that elisa-detectable circulating antibodies to m paratuberculosis are widespread in cattle of florida.19902332370
