Immune Responses to Plague Infection in Wild Rattus rattus, in Madagascar: A Role in Foci Persistence?
BACKGROUND Plague is endemic within the central highlands of Madagascar, where its main reservoir is the black rat, Rattus rattus. Typically this species is considered susceptible to plague, rapidly dying after infection inducing the spread of infected fleas and, therefore, dissemination of the disease to humans. However, persistence of transmission foci in the same area from year to year, supp...
متن کاملReproductive Toxicity of Triptolide in Male House Rat, Rattus rattus
The aim of study was to investigate the toxic effect of triptolide fed in bait on reproduction of male house rat, Rattus rattus. Feeding of cereal based bait containing 0.2% triptolide to male R. rattus for 5 days in no-choice feeding test, leading to mean daily ingestion of 20.45 mg/kg bw of triptolide, was found effective in significantly (P ≤ 0.05) reducing sperm motility and viability in ca...
متن کاملPlague Circulation and Population Genetics of the Reservoir Rattus rattus: The Influence of Topographic Relief on the Distribution of the Disease within the Madagascan Focus
BACKGROUND Landscape may affect the distribution of infectious diseases by influencing the population density and dispersal of hosts and vectors. Plague (Yersinia pestis infection) is a highly virulent, re-emerging disease, the ecology of which has been scarcely studied in Africa. Human seroprevalence data for the major plague focus of Madagascar suggest that plague spreads heterogeneously acro...
متن کاملA survey on helminthic infection in mice (Mus musculus) and rats (Rattus norvegicus and Rattus rattus) in Kermanshah, Iran
Parasitic infections of rodents can compromise scientific research as well as the health of the animals and humans. Based on previous studies, infection rate of parasitic helminths is different in various regions of Iran. The current survey was aimed to determine endoparasitic helminths infection in 138 trapped rodents of Kermanshah county, Iran. Mice and rats were trapped using metal snares fr...
متن کاملIdentification of alpha2u-globulin and bound volatiles in the Indian common house rat (Rattus rattus).
The alpha2u-globulin (alpha2u) is a pheromone carrier urinary protein believed to be relevant for sexual communication among rats and is characterized in laboratory rats. In the present study 17 kDa protein and the bound pheromones were characterized in a population of wild-type Indian common house rat (Rattus rattus). The protein was purified by two runs of Sephadex G-50 chromatography and ana...
