bacterial pathogens isolated from cultured bullfrogs (rana castesbeiana).a commercial bullfrog (rana castesbeiana) operation in south georgia had multiple epizootics of systemic bacterial infections over a 3-year period, 1998-2000. a number of potential pathogens (aeromonas hydrophila, chryseobacterium (flavobacterium) meningosepticum, chryseobacterium (flavobacterium) indolgenes, edwardsiella tarda, citrobacterfreundii, pseudomonas spp., and (streptococcus iniae) were isolated from various tissues. clinically, frogs demonstrated acute onset of torticolis, stupor, an ...200212296400
pathologic findings in larval and juvenile anurans inhabiting farm ponds in tennessee, usa.amphibian populations are declining globally, yet general pathologic surveys for free-ranging amphibians are uncommon. pathologic surveys are necessary to provide insight into the impacts of humans on emergence of pathogens in amphibian populations. during 2005, 104 american bullfrog (rana catesbeiana) and 80 green frog (rana clamitans) larvae and 40 green frog juveniles were collected from farm ponds in tennessee, and complete necropsies were performed. diagnostic testing included bacterial cul ...200919395741
tadpoles fed supplemented diet with probiotic bacterium isolated from the intestinal tract of bullfrog lithobates catesbeianus: haematology, cell activity and electron microscopy.the aim of this study is to select and isolate autochthonous bacteria with probiotic potential for use in a supplemented diet for bullfrog tadpoles, lithobates catesbeianus. a total of 20 strains of lactic acid bacteria were isolated. nine out of these were used in the following in vitro assays: antagonism against pathogenic bacteria (ant), antimicrobial activity from extracellular compounds (mic), tolerance to bile salts (tbs), ph reduction, protease production, sensitivity to antimicrobial tet ...201729174701
