Thiothrix spp., sulfide‐oxidizing mixotrophic bacteria, were sampled from visible colonies in the Floridan aquifer in several underwater caves, sinkholes, and springs below the water table in North Florida. Bacteria samples were collected by cave d

We have developed a method to enrich, isolate, and identifyThiothrix spp. in environmental samples. This procedure employs low concentrations of organic compounds, the addition of reduced sulfur compounds (sulfide or thiosulfate), and preparation wit

The mussel fauna of many North American waters is declining, probably due to a combination of factors. The factors may include channelization and impoundment of rivers where the mussels once thrived, as well as the influx of pesticides and metal poll

Populations of freshwater mussels have been declining for several decades due to habitat destruction, pollution and sedimentation. Efforts to propagate rare and endangered species in the laboratory have been hampered by their need for fish as hosts d

The purpose of this study was to immunologically characterize soft tick salivary antigens. BALB/c mice hyperimmunized with salivary gland extract prepared from Ornithodoros talaje (Guerin-Meneville) were observed to develop high titers of antitick sa

An ELISA previously developed for the rapid detection of Salmonella enteritidis (SE) in environmental samples was modified and applied to food samples. A sandwich ELISA was designed that employs affinity-purified rabbit polyclonal antibodies for the

New Zealand White rabbits were repeatedly infested with Ornithodoros turicata (Duges), Ornithodoros talaje (Guerin-Meneville), and Ornithodoros coriaceus (Koch) at 2-wk intervals. Blood samples were taken from each animal 10 d after each infestation

Historically, methods used to identify Thiothrix spp. in environmental samples have been inadequate because isolation and identification procedures are time-consuming and often fail to separate Thiothrix spp. from other filamentous microorganisms. We

We have developed a enzyme-linked immunosorbent assay (ELISA) using a monoclonal antibody (ASCII) for the detection of Salmonella enteritidis in environmental samples. ELISA was used to test for sensitivity and specificity of ASCII. 38 other species

The host antibody response of CD1 mice resulting from sequential exposures to two species of Ornithodoros ticks was isotyped (ELISA) in an effort to determine the mechanism for the development of acquired resistance. In addition, salivary gland prote
