Molecular detection and identification of tick-borne bacteria and protozoans in goats and wild Siberian roe deer (Capreolus pygargus) from Heilongjiang Province, northeastern China

Small ruminants are important hosts for various tick species and tick-associated organisms, many of which are zoonotic. The aim of the present study was to determine the presence of tick-borne protozoans and b...

Transmission of vector borne pathogens are particularly sensitive to these changes due to the complexity of their cycle, where the transmission of a...

In the case of vector-borne diseases, changes in vector-host interaction require a continuous monitoring since this parameter con...

Abstract Tick-borne haematozoans cause severe diseases in domestic animals, and some of them have zoonotic potential. The results of previous studies in Europe point to the important role of foxes in natural endemic cycles of several tick-borne pathogens, including protozoa. The aim of the present research was to acquire information on the prevalence and distribution of tick-borne protozoan parasites among foxes in Serbia. Legally hunted foxes from 14 localities throughout Serbia were analysed. Spleen samples were collected from 129 animals and tested for the presence of Babesia spp. and Hepatozoon spp. by PCR. In...

Abstract The global impact of bovine babesiosis caused by the tick-borne apicomplexan parasites Babesia bovis, Babesia bigemina and Babesia divergens is vastly underappreciated. These parasites invade and multiply asexually in bovine red blood cells (RBCs), undergo sexual reproduction in their tick vectors (Rhipicephalus spp. for B. bovis and B. bigemina, and Ixodes ricinus for B. divergens) and have a trans-ovarial mode of transmission. Babesia parasites can cause acute and persistent infections to adult naïve cattle that can occur without evident clinical signs, but infections caused by B. bovis are associa...

This study provides basic knowledge that is necessary to initiate Kyasanur Forest Disease (KFD) prevention programs in these areas. Ticks were sampled from Wayanad districts of Kerala from domestic animals and identified morphologically. A total of 195 cattle searched, in which 168 (86.15%) cattle were infested with ticks and a total of 3633 ticks comprising three genera and seven species were collected,Rhipicephalus microplus (52.71%) was prevalent species followed byHaemaphysalis bispinosa (16.9%),Rhipicephalus decoloratus (15.77%),Haemaphysalis turturis (11.42%),Rhipicephalus sanguineus (1.32%),Amblyomma integrum (1.15%...

This study is the first report on prevalence and molecular characterization of A. phagocytophilum strains and Babesia species in roe deer and red deer in Norway. The high infection and coinfection rates with A. phagocytophilum and Babesia spp. in red deer and roe deer suggest that these cervids may play important role in the transmission of single and multiple infections. Climate change can potentially increase the density and distribution of vector and thus enhance the risk of tick-borne infections in Norway.Graphical abstract

We report here the detection of E. chaffeensis in a study on marsh deer (Blastocerus dichotomus) mortality in Argentina, in different time periods between 2007 and 2016. Four deer, from two distinct populations, were positive for E. chaffeensis through molecular methods. Additionally, the variable-length PCR target (VLPT) region of positive samples was genotyped. Our results provide the first evidence of E. chaffeensis in autochthonous Cervidae from Argentina, contributing to uncover the distribution of this tick-borne infection in South America.Graphical abstract
