Studies on theileriosis in goats from Karnataka, South India

Abstract

A study was conducted to determine the prevalence of theileriosis in goats from southern districts of Karnataka. Out of 47 goat blood samples examined by microscopy, 68.08% (32/47) were positive for spp. The parasitemia ranged from 1.0 to 1.8 and 0.1-0.9% in clinical and carrier animals respectively. Out of 325 ticks collected from goats, 92.6 (301) and 7.38 (24)% of the ticks were found to be and respectively. (90.15%) was found to be the predominant species followed by (6.7%), (1.84%), (0.61%) and (0.61%). The present study indicated that caprine theileriosis is an endemic disease in Karnataka and suggested that and ticks may play a role in transmission of the disease.

Identification of Theileria spp. and investigation of hematological profiles of their infections in goats in Hainan Island, China

“…This is consistent with the presentation of tick-borne blood parasitic disease reported in other literature [ 2 ]. However, the significant increase of MCH in this study is inconsistent with the substantial decrease in MCH reported by Shruthi [ 20 ], which may be due to that the different infecting Theileria species. However, this needs to be investigated in subsequent studies.…”

Effect of Buparvaquone in successful therapeutic management of Caprine Theileriosis

“…Theileria lestoguardi, T. uilenbergi, and T. luwenshuni are highly harmful species for small ruminants, while T. ovis and T. separate are low pathogenic species (Yin et al, 2007) [10] . Previous observations provide support for the clinical symptoms in this case (Shruthi et al, 2017) [8] . Anaemia was the cause of the dyspnea and tachycardia.…”

“…The presence of comma-and parachute-shaped piroplasms in the red blood cells (RBCs) in this goat case confirmed theileria infection, which was also described by Altay et al (2007) [3] . Pleomorphic piroplasms in red blood cells of Theileriaaffected goats, comprising rod, pear, dot, nail, comma, oval, parachute, round, and semi-comma shapes, were reported by Shruthi et al (2017) [8] in the Indian state of Karnataka. Microscopical analysis of stained blood smears can be used as a quick confirmatory diagnostic test for the start of curative treatment in animals affected by Theileriosis, even though it is less sensitive than molecular techniques like polymerase chain reaction (PCR) for the detection of low levels of parasitaemia in theileriosis affected animals (Rabeya Begam et al, 2019) [7] .…”
