“…In case of buffaloes, significantly higher prevalence of A. marginale was recorded in non-descript breed than pure breeds (12.07% vs 3.64%, p<0.05). Difference in innate and acquired immunity, animal husbandry and managemental practices might be the contributing factor towards higher prevalence of haemoprotozoan infections in ND breeds compared to pure breed Velusamy et al, 2014;Bhatnagar et al, 2015;Sharma et al, 2015 a &b).…”

“…Prevalence of Haemoprotozoan parasites has been reported in animals of different parts of India (Agrawal et al, 2003;Muraleedharan et al, 2005;Shahnawaz et al, 2011;Vahora et al, 2012;Arun Kumar et al, 2013;Velusamy et al, 2014;Kohli et al, 2014;Sharma et al, 2015a). However, true status of haemoprotozoan infections has not yet been explored in bovines in and around Junagadh, South western Gujrat of India which is a rich source of livestock with breeds like Gir cattle, Jaffrabadi buffalo and the agroecological and geo-climatic conditions of this region are highly favourable for growth and multiplication of natural vectors of these diseases.…”

A total of 480 suspected blood samples were collected from cattle (n=254) and buffaloes (n=226) during the study period from September 2011 to December 2014 for determination of prevalence of haemoprotozoan parasites from South Western Gujarat (Junagadh). The conventional optical microscopy of Giemsa stained blood smears revealed that 37% of cattle and 38.93% of buffaloes were infected with haemoprotozoan parasites including Anaplasma marginale, Babesia bigemina, Trypanosoma evansi and Theileria annulata. The animals infected with haemoprotozoan diseases showed lower total erythrocyte count (TEC), haemoglobin (Hb), packed cell volume (PCV), mean corpuscular haemoglobin concentration (MCHC) and higher total leukocyte count (TLC) and mean corpuscular volume (MCV). Incidence of haemoprotozoan infection between the breeds differed significantly (P<0.05). Haemoprotozoan infections were recorded significantly higher (P<0.001) in monsoon season followed by summer and being lowest in winter season in cattle. Over all prevalence in female animals were higher than male counterparts. In both the species, over all higher prevalence of babesiosis was recorded in comparison to other haemoprotozoan diseases and the difference being statistically non-significant (p>0.05). The prevalence of B. bigemina in bovines was associated with various risk factors namely age, season and breed (p0.05). Sex wise females recorded apparently higher infection rates than males. The multivariate logistic regression models showed that the risk of babesiosis was significantly higher in rainy season (OR=5.18, P=0.003) followed by summer (OR=3.9, P=0.019) compared to winter season. Conversely, in buffaloes, the risk of babesiosis was significantly higher in summer season (OR=9.0, P=0.004) followed by rainy (OR=7.43, P=0.008) compared to winter season. The risk for anaplasmosis in buffaloes increased by 3.46 times (OR=3.64, p=0.027) in non descriptive breed compared to well defined breed.

“…For this reason, milk in India is generally produced by less productive native cattle or buffalo, or by Bos indicus*Bos taurus cross-breed cattle [1] that have greater productivity than native breeds. However, even among crossbred cattle T. annulata can cause acute pathology while in native breeds and buffaloes infection manifests primarily as a subclinical form [2,3]. Economic loss due to tropical theileriosis in India is estimated to be US$800 million [4] but this is likely to be an underestimate as substantial losses from subclicinal carrier infection are rarely captured [5].…”

“…Tamil Nadu is one of the top 10 regions of milk production in India, where a mixture of breed and host types are reared [3], with a higher proportion of cross-breeds in its dairy herds than other regions [1]. Episodes of tropical theileriosis are known to occur persistently in the central region of the state.…”

In India, disease of cattle caused by tick-borne pathogens (TBP) constrains the rearing of high yielding Bos taurus dairy breeds that often develop clinical, fatal disease. Bos indicus and bufflao show resistance to TBP infection, and this has led to a policy of rearing crossbred indicus-taurus cattle. On dairy farms, co-grazing more resistant animals alongside crossbreeds could contribute positively (by removing potentially infective ticks) or negatively (by acting as a reservoir for infection). We investigated epidemiological factors that contribute to the prevalence of five tick-borne pathogens with links to milk-yield in co-grazed host types in dairy farms of two regions of Tamil Nadu, India; a region of high dairy production importance. A high prevalence of T. annulata and Anaplasma spp. was detected, but with lower prevalence in the Cauvery Delta than in the Northwestern zone. A strict host-type association with prevalence was observed: buffaloes had lower prevalence of TBP than cattle; and native breeds had a lower prevalence of Anaplasma spp. than crossbreeds. The results indicate that while susceptibility to becoming a carrier animal for TBP depends on exposure to ticks; aspects of resistance are determined by host type independent of tick exposure. There was no clear evidence that co-grazing, with more resistant host types, will provide a positive contribution (protective effect) to crossbreeds with greater milk productivity.

Objectives:Anaplasmosis is an economically important disease affecting cattle, buffalo, sheep, goat etc. The study was conducted to determine the prevalence, potential risk factors and molecular identification of circulating Anaplasma spp. in goats in Chattogram district, Bangladesh. Material and methods:Four hundred blood samples were collected from goats of different ages, breeds, sex, coat color and body condition. These goats were selected based on some inclusion criteria through the period of July 2017 to June 2018. Samples were examined microscopically (Giemsa staining method) followed by polymerase chain reaction (PCR) and sequencing to identify of Anaplasma spp. Results:The overall prevalences were estimated 5.75% (23/400) and 15.75% (63/400) by microscopy and PCR, respectively. Anaplasma ovis (A. ovis) and Anaplasma marginale (A. marginale) were identified with the prevalence of 14.75% (59/400) and 1.0% (4/400), respectively through PCR. Among different risk factors, jamnapari breed (p = 0.027), no use of acaricide (p = 0.025) and presence of tick (p < 0.01) were found to be significantly associated with anaplasmosis. Sequence analysis of msp4 gene revealed that, Anaplasma spp. detected in the present study were highly similar with those of China,
