| occurrence and experimental infection of toads (bufo marinus and b. granulosus) with mycobacterium chelonei subsp. abscessus. | in a survey of 234 amazonian toads and frogs, six strains of mycobacterium chelonei subsp. abscessus were isolated from the liver or spleen of four of 66 bufo marinus (6.1%) and from the kidney or peritoneal fluid of two of 86 b. granulosus (2.3%). there were no histopathological lesions in the viscera of the infected animals. experimental infection of 29 captive b. marinus and b. granulosus, by the intraperitoneal route, with a pooled inoculum of m. chelonei subsp. abscessus caused five deaths ... | 1984 | 6438324 |
| splenic immunotoxicity in developing cane toads (rhinella marina) from bermuda. | the impacts of contaminated sediment from 2 ponds in bermuda on immune function in newly metamorphosed cane toads were examined. in the present study, a partial life-cycle experiment exposing gosner stage 20 cane toad tadpoles to pond sediment and laboratory culture water through metamorphosis and into a juvenile state was performed. a basic immunology battery, including general necropsy, spleen somatic index, spleen white pulp content, splenocyte tissue density, and splenocyte viability, was co ... | 2016 | 26991249 |
