This study compares the prevalence of ixodid tick species on cattle and goats in Maputo Province. Adult ticks as well as the nymphs of three species, and only the adults of two species were collected from sets of five cattle at 21 localities throughout the province and compared with those collected from similar sets of goats at the same places. Amblyomma hebraeum adults and/or nymphs were prese...

A new stunt nematode, from soil around the roots of coconut (Cocos nucifera L.) and rice (Oryza sativa L.) from Karachi, Pakistan, is described and illustrated as Tylenchorhynchus qasimii n. sp. This new species is characterized by having females with 3-4 head annules, anteriorly directed stylet knobs, absence of post anal extension, presence of rounded sperm filled spermatheca and conoid to bl...

We report a partial genome sequence for the Coxiella-like endosymbiont strain CLE-RmD, assembled from metagenomics data obtained from the southern cattle tick (Rhipicephalus microplus) Deutsch strain.

background: rhipicephalus sanguineus and hyalomma marginatum are the most common spe­cies in sheep herds in northeast of iran. there is preliminary evidence that these species may be the vectors of babesia ovis in iran. we carried out two experiments in mashhad area, khorasan razavi province to determine whether b. ovis could be transovarially transmitted by r. san­guineus and h. marginatum . m...

Since the transition from terrestrial to marine environments poses strong osmoregulatory and energetic challenges, temporal and spatial fluctuations in oceanic salinity might influence salt and water balance (and hence, body condition) in marine tetrapods. We assessed the effects of salinity on three species of sea snakes studied by mark-recapture in coral-reef habitats in the Neo-Caledonian La...

The present investigation is related to the frequency of infection and to the gross and microscopic lesions associated to the presence of trichurid worms in 50 ring-necked pheasants (Phasianus colchicus) from backyard flocks in the state of Rio de Janeiro, Brazil. In the investigated birds, the overall infection rate was of 74%, with the presence of Eucoleus perforans with 72% of prevalence and...

A cross-sectional study was conducted to determine the prevalence and risk factors for ectoparasites infestation in sheep in three agro-ecological zones in central Oromia, Ethiopia, from October 2009 to April 2010. The study revealed that 637 (48.1%) of the 1325 sheep examined were infested with one or more ectoparasites. The ectoparasites identified were Bovicola ovis (27.2%), Melophagus o...

It has been shown experimentally from three repeated infestations that dogs were unable to develop effective resistance against dog ticks: rhipicephalus sanguineus Latreille, 1806 and haemaphysalis leachi leachi Audouin, 1826. The number of successive engorged females recovered from dogs at the second and third infestations in both species were not significantly less (P>0.05) than the number re...
