BACKGROUND Q fever is a widespread zoonotic disease caused by Coxiella burnetii. Ticks may act as vectors, and many epidemiological studies aim to assess C. burnetii prevalence in ticks. Because ticks may also be infected with Coxiella-like bacteria, screening tools that differentiate between C. burnetii and Coxiella-like bacteria are essential. METHODS In this study, we screened tick specime...

BACKGROUND Anaplasmosis is an important issue for animal breeders in terms of economic losses as well as a health concern to human. Ticks are considered as the main vector of this disease. Lack of documented information about Anaplasma species in Iran was the scope of this study to determine the population of ticks and the presence of Anaplasma in ticks, domestic ruminants and also human beings...

The objective of this study was to assess the host status of the three largest southern African wild ruminants, namely giraffes, Giraffa camelopardalis, African buffaloes, Syncerus caffer, and eland, Taurotragus oryx for ixodid ticks. To this end recently acquired unpublished data are added here to already published findings on the tick burdens of these animals, and the total numbers and specie...

Factors that directly impact horizontal transmission of the microsporidium Amblyospora albifasciati to its intermediate copepod host, Mesocyclops annulatus were examined in laboratory bioassays. Results were evaluated in relation to life history strategies that facilitate persistence of the parasite in natural populations of its definitive mosquito host, Ochlerotatus albifasciatus. A moderately...

Several ixodid tick species are shared between domestic cattle and African buffaloes (Syncerus caffer). So too, are a number of tick-borne diseases. The aim of the study was to compare the species composition of ticks that infest cattle and buffaloes utilising the same habitat within the Tsavo Conservation Area, Kenya. To this end, 25 cattle and 62 buffaloes were each opportunistically samp...

We evaluated the potential of Mesocyclops annulatus as a control agent of Aedes aegypti in La Plata city (Argentina). Mosquito larval survivorship due to predation by these copepods was estimated at weekly intervals during the oviposition period of A. aegypti. Mean weekly A. aegypti larval survivorship in cylindrical plastic containers (12 cm height and 11 cm diameter) with copepods was signifi...

A method for the identification of three ixodid tick species; the cow tick (Boophilus annulatus), the camel tick (Hyalomma dromedarii) and the cattle tick (Hyalomma anatolicum excavatum) based on restriction enzyme analysis of the second internal transcribed spacer (ITS-2) in the nuclear ribosomal DNA was adopted. PCR products with MW 1375 bp, 1650 bp and 1835 bp from B. annulatus, H. dromedari...

The purpose of this study was to determine the species spectrum of ticks infesting goats owned by resource-limited farmers in the state-owned communal land areas of Zimbabwe. Ticks were collected from goats at a single locality within each of 5 communal land areas, and a total of 14 ixodid tick species was recovered. The most numerous tick was Rhipicephalus evertsi evertsi, which was present in...
