This paper describes five additional Brazilian human cases of polycystic hydatid disease due to Echinococcus vogeli, reviews the previous cases reported in Brazil, including one report of E. oligarthus (20 in total), and some epidemiological aspects of this disease which is no longer a curiosity but rather a problem that is not medically easy to handle. Its presence should be expected in any ru...

A major cause of taphonomic loss is bone destruction by scavengers. Having monitored nine sheep bone scatters and two modern sheep carcasses near a farmstead and in a nearby forest clearing, it was hypothesized that the proximity of the settlement influenced multiple non-human bone modificator activities. This observation was tested by an experiment in which the rate of transport was measured i...

Although it is a common infestation in the Asian region, human gnathostomiasis due to the third stage larvae of Gnathostoma species has not been reported in Sri Lanka up to now (1). The definitive hosts of this nematode are felids and canids, the former being particularly important. Humans are aberrant hosts and the disease is characterised by peripheral eosinophilia and a variety of local mani...

A nested polymerase chain reaction assay was used to determine the presence of Ehrlichia chaffeensis, E. canis, and E. ewingii DNA in blood samples of free-ranging coyotes from central and northcentral Oklahoma. Of the 21 coyotes examined, 15 (71%) were positive for E. chaffeensis DNA; none was positive for E. canis or E. ewingii. Results suggest that E. chaffeensis infections are common in fre...

An extensive debate concerning the origin and taxonomic status of wolf-like canids in the North American Great Lakes region and the consequences for conservation politics regarding these enigmatic predators is ongoing. Using maternally, paternally and biparentally inherited molecular markers, we demonstrate that the Great Lakes wolves are a unique population or ecotype of gray wolves. Furthermo...

toxoplasma gondii as an apicomplexan zoonotic parasite is able to infect humans and almost all other warm-blooded animals. wild and domestic felids are the main definitive hosts. also, canids such as dogs and jackals have been introduced as mechanical vectors since t. gondii oocysts can pass their intestinal tract and spread by feces in environment. toxoplasmosis is a common zoonotic disease in...
