Explanations for the evolution of pathogen-induced fecundity reduction usually rely on a common principle: the trade-off between host longevity and reproduction. Recent advances in nutritional research have, however, challenged this assumption and shown that longevity and reproduction are not inextricably linked. In this study, we showed that beetles infected by cysticercoids of the tapeworm Hy...
A survey of intestinal parasitism was conducted at Yaviza, a town in eastern Panama's Province of Darien. Single stool specimens from 202 persons, representing 11 percent of the town's total population, were examined. In all, 181 (90 per cent) of the specimens examined were found positive for one or more potentially pathogenic parasites. The most common parasite found was Trichuris trichiura, w...
Parasites have profound effects on host ecology and evolution, and the effects of parasites on host ecology are often influenced by the magnitude of host susceptibility to parasites. Many parasites have complex life cycles that require intermediate hosts for their transmission, but little is known about the genetic basis of the intermediate host's susceptibility to these parasites. This study e...
Understanding why some exotic species become widespread and abundant in their colonized range is a fundamental issue that still needs to be addressed. Among many hypotheses, newly established host populations may benefit from a "parasite release" through impoverishment of their original parasite communities or reduced infection levels. Moreover, the fitness of competing native hosts may be affe...
We report the draft genome of Brevundimonas diminuta strain XGC1, isolated from a tuberculosis-infected patient in Gujarat, India. This study also reveals that the B. diminuta XGC1 strain has acquired mutation to confer resistance to quinolone drugs.
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 many helminth infected hosts the number of eosinophils increases dramatically, often without any concurrent increases in the number of other leukocytes, so that eosinophils become the dominant cell type. Many experimental investigations have shown that the eosinophilia is induced by interleukin-5 (IL-5) but its functional significance remains unclear. Mice genetically deficient in IL-5 (IL-5...
