Murine typhus, an acute febrile illness caused by Rickettsia typhi, is distributed worldwide. Mainly transmitted by the fleas of rodents, it is associated with cities and ports where urban rats (Rattus rattus and Rattus norvegicus) are abundant. In the United States, cases are concentrated in suburban areas of Texas and California. Contrary to the classic rat-flea-rat cycle, the most important ...

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...

Cutaneous leishmaniasis (CL) is a neglected clinical form of public health importance that is quite prevalent in the northern and eastern parts of Egypt. A comprehensive study over seven years (January 2005-December 2011) was conducted to track CL transmission with respect to both sandfly vectors and animal reservoirs. The study identified six sandfly species collected from different districts ...

Background: Grass Kebar (Biopytum petersianum Klotzch) is one of Indonesian medicinal plants, which can only be found in Kebar sub-district, Manokwari, Irian Jaya. This plant is mainly used by the community Manokwari to maintain the fertility of women of reproductive organs. This study aims to determine the effect of extract Grass Kebar dose on the fertility of the uterus and the number of prog...

Based on previous observations that newly inserted LINEs and SINEs have particularly long 3' A-tails, which shorten rapidly during evolutionary time, we have analyzed the rat and mouse genomes for evidence of recently inserted SINEs and LINEs. We find that the youngest predicted subfamilies of rodent identifier (ID) elements, a rodent-specific SINE derived from tRNA(Ala), are preferentially ass...

The responses of 2- and 8-day-old rats (Rattus norvegicus) and hamsters (Mesocricetus auratus) to thermal stimulation were assessed in 4 experiments. In Experiment 1, the surface underlying the pup was cooled, and the latency to escape to a region of warmth was measured. Experiment 2 required pups to locomote farther to gain access to warmth. Experiment 3 was similar to Experiment 1 except the ...

Study on the prevalence of ectoparasites and haemoparasites of domestic rats in parts of Akure South Local Government was carried out from July to September 2015. The rodents were trapped using locally fabricated traps. Body brushing technique was used to collect their ectoparasites. Blood samples from each rat were collected and examine using standard biological techniques. Specie of rodents c...

Strongyloides venezuelensis is a parasitic nematode of rats which is frequently used as a model to study human and animal strongyloidiasis. The aim of this study was to evaluate the correlation between parasitological and molecular diagnosis in Strongyloides venezuelensis infection. PCR assays were used to detect S. venezuelensis DNA in fecal samples obtained from experimentally infected Rattus...

Using an elevated plus maze apparatus and an activity cage, behavioral changes in Rattus norvegicus concomitantly infected by Toxocara canis and Toxoplasma gondii were studied, during a period of 120 days. Rats infected by Toxocara canis or Toxoplasma gondii showed significant behavioral changes; however, in the group coinfected by both parasites a behavioral pattern similar to that found in th...
