“…may be involved in the transmission cycle of many pathogens (potentially including A. phagocytophilum) though further investigations such as, transmission experiments, should be carried out to prove the vector competence of these tick species. Babesia gibsoni is transmitted by H. longicornis in Asia (Jain Jose et al, 2018). Though this tick was not detected in the current study, one dog was positive for B. gibsoni.…”

“…Co-infection with H. canis in dogs from India was also reported by Abd Rani et al [ 9 ]; nonetheless, co-infection cases in this study were of a considerably lower prevalence and involved B. vogeli and H. canis in Mumbai (14%) and Delhi (7%), and not B. gibsoni . Another study from Kerala in southern India focused on the presence of hemoparasite DNA in dogs and ticks infesting them as detected by multiplex PCR [ 24 ]. This study reported the presence of B. vogeli , E. canis and B. gibsoni in R. sanguineus ( s.l. )…”

“…This study reported the presence of B. vogeli , E. canis and B. gibsoni in R. sanguineus ( s.l. ) ticks, while Haemaphysalis bispinosa ticks harbored only B. gibsoni , thus arousing the suspicion (which needs further experimental substantiation) that this tick species may also serve as a vector of B. gibsoni , in addition to H. longicornis and H. hystricis [ 19 , 20 , 24 ].…”

BackgroundInformation on the status of vector-borne pathogens among canines in Northeast India is lacking, particularly for the states of Mizoram and Tripura close to the Myanmar border. Blood samples collected from 130 dogs, 80 from Mizoram and 50 from Tripura, were examined in this study.MethodsPolymerase chain reaction (PCR) was performed for filariid worms, Babesia, Hepatozoon, Ehrlichia and Anaplasma spp. and DNA sequencing was then carried out to identify pathogens at the species level.ResultsVector-borne pathogens were detected in 52% (68/130) of the sampled dogs. The most prevalent pathogen was Babesia gibsoni detected in 56/130 (43%) dogs, followed by Hepatozoon canis in 50/130 (38%), Anaplasma platys in 4/130 (3%), B. vogeli in 4/130 (3%), Acanthochelionema reconditum in 3/130 (2%) and Dirofilaria immitis in 2/130 (2%). Forty-four dogs (34%) were co-infected with two or more pathogens. The most common co-infection observed was with B. gibsoni + H. canis (34%) followed by triple-infection with B. gibsoni + H. canis + A. platys (3%), and B. gibsoni + B. vogeli + H. canis (3%). The infection rate was higher in Mizoram (58%) than in Tripura (44%).ConclusionsThe high prevalence of infection in the studied dog population, especially with B. gibsoni and H. canis, indicates that vector-borne diseases pose a serious threat to the health of dogs in this area of Northeast India. Prevention of vector-borne diseases by using topical acaricides and heartworm preventative treatment would be of great benefit for reducing the threat of vector-borne diseases in the study area.

“…A multiplex PCR assay was recently reported in which Ehrlichia canis, B. vogeli and B. gibsoni DNA can simultaneously be detected in R. sanguineous ticks collected from infected dogs from India [73]. The assay was previously developed and used successfully for the detection of the same parasites in samples derived from sick dogs [74]. It was also found that Hemaphysalis bispinosa ticks were infected with B. gibsoni alone.…”

Challenges in Tick-Borne Pathogen Detection: The Case for Babesia spp. Identification in the Tick Vector

et al. 2021

The causative agents of Babesiosis are intraerythrocytic protozoa of the genus Babesia. Babesia parasites are present around the world, affecting several mammals including humans, pets and livestock, hence its medical and veterinary relevance. Babesia spp. detection in its invertebrate host is a main point in understanding the biology of the parasite to acquire more knowledge on the host–Babesia–vector interactions, as increasing knowledge of the Babesia lifecycle and babesiosis epidemiology can help prevent babesiosis outbreaks in susceptible mammals. The aim of the present review is to highlight the newest findings in this field, based on a bibliographic compilation of research studies recently carried out for the detection of the main Babesia species found in tick vectors affecting mammalian hosts, including the different tick stages such as adult ticks, larvae, nymphs and eggs, as well as the detection method implemented: microscopic tools for parasite identification and molecular tools for parasite DNA detection by conventional PCR, nested-PCR, PCR-RFLP, PCR-RLB hybridization, real time-PCR, LAMP and RAP assays. Although molecular identification of Babesia parasites has been achieved in several tick species and tissue samples, it is still necessary to carry out transmission experiments through biological models to confirm the vectorial capacity of various tick species.
