It has been known that as a result of diabetes several diseases occur in organisms such as parasitic infection. This gives rise to inflammatory conditions associated with mast cells. For the purpose of observing mucosal cells in bladder tissue, streptozotocin diabetic rat bladders were examined with light and electron microscope. A microscopic study of serial sections revealed numerous mast cel...

The sanitary conditions of 13 animal houses in nine public institutions in Minas Gerais, and the presence of endo and ectoparasites of mice and rats colonies kept in these facilities were evaluated. Data about barriers to prevent the transmission of diseases and a program of sanitary monitoring were obtained through a questionnaire and local visit. Parasitological methods were performed for dia...

BACKGROUND Rats live in close proximity to human populations. Feral rodents are known to transmit diseases and act as reservoir hosts to many zoonotic parasites that pose health risks to humans. The aim of this study is to investigate endoparasitic infections in commensal rats and shrews caught in traditional wet markets in Taichung City, Taiwan. METHODS A total of 51 commensal wild rodents a...

In Japan, pea aphids Acyrthosiphon pisum mainly feed on vetch and clover, and many aphid clones produce more progeny on vetch than on clover. In this context, particular genotypes of the facultative symbiont Regiella insecticola enhance reproduction of infected pea aphids specifically on clover, thereby broadening the suitable food plant range of the insect. A species that is sympatric to A. pi...

Evaluating the effect of parasites on population size is essential for designing management and conservation plans of wild animal populations. Although knowledge in this area is scarce in cetaceans, current evidence suggests that species of the nematode genus Crassicauda may play an important regulatory role in some populations. In the present study, a semiparametric regression technique was ap...

In this study, the epidemiology and clinical findings of scorpion stings in the Sanliurfa province of Turkey was evaluated between May and September 2003. Data obtained from questionnaires was evaluated and the identification of scorpions collected from the region was carried out in the laboratory. It was determined that of the species of scorpions only Androctonus crassicauda was collected. Th...

during an investigation on the endoparasites of rodents in ahvaz, khuzestan province, south west iran, a total of 90 rodents including 14 mus musculus,4 rattus rattus and 72 r. norvegicus were trapped from different localities of ahvaz and its suburbs, during 1998- 2000, using live traps. examination of different tissues, identification of parasite species and serological tests were carried out...
