Enhanced proliferation and efficient transmission of Candidatus Liberibacter asiaticus by adult Diaphorina citri after acquisition feeding in the nymphal stage
It is suggested that multiplication of the bacterium into the psyllids is essential for an efficient transmission and show that it is difficult for adults to transmit the pathogen unless they acquire it as nymphs. Expand
Sulfolobus hakonensis sp. nov., a novel species of acidothermophilic archaeon.
A microbial strain that was isolated from a hot spring at a geothermal area in Hakone, Japan, was a facultative chemolitho-autotroph that required aerobic conditions for growth and belonged to a new Sulfolobus species, for which the name is proposed. Expand
Evaluation of aviguard, a commercial competitive exclusion product for efficacy and after-effect on the antibody response of chicks to Salmonella.
The study showed that AG protected chicks from overwhelming colonization by salmonellae, and neither altered the antigenic proteins of infecting salmonella nor their recognition by specific antibodies produced in response to the infection. Expand
Mutagenicity of carcinogenic mycotoxins in Salmonella typhimurium.
Fifteen mycotoxins and two chemically modified toxins were tested for mutagenic ability in the His + revertant assay with the use of Salmonella typhimurium TA 98 and TA 100 and failed to demonstrate mutagenicity. Expand
Chronic toxicity and hepatocarcinogenicity of (+) rugulosin, an anthraquinoid mycotoxin from penicillium species: preliminary surveys in mice.
The data suggest that RUG is possibly a weak hepatocarcinogen for male mice with a potency les than one tenth of (-) luteoskyrin. Expand
Toxicological approaches to the metabolities of fusaria. XII. Fate and distribution of T-2 toxin in mice.
Tissue distribution, excretion and fate of T-2 toxin, a potent cytotoxic mycotoxin of Fusarium species, were examined in mice and rats by using tracer method as well as chromatographic technique.Expand
Time course of coproantigen excretion in Echinococcus multilocularis infections in foxes and an alternative definitive host, golden hamsters.
Observations indicate that the coproantigen detection assay is a safe and useful method, not only for diagnosis in the definitive host of E. multilocularis, but also for monitoring parasite development and change in parasite burden during an experimental infection. Expand
