Prevalence of haemoprotozoan diseases in cattle of Cauvery delta region of Tamil Nadu

In this study Anaplasmosis (14%) was highly prevalent during the winter season and Babesiosis (13.73%) was highly prevalent during summer months followed by Anaplasmosis (9.8%) and Theileriosis (7.8%), the lowest prevalence of Trypanosomiasis was observed during the rainy season. The s easonal variation in prevalence of haemoprotozoan disease might be due to influence of climatic factors on density of vector population in that geographical area. Haemogram revealed decreased level of haemoglobulin, packed cell volume and total erythrocyte count. The serum biochemistry revealed elev ated level of liver enzyme Asparate transaminase enzyme. All haemoparasitaemic animals were treated with specific drugs and recovered successfully.

In this study, we applied complementary in silico approaches to modeling how Anaplasma phagocytophilum infection modulates tick vector regulome. This proof-of-concept research provided support for the use of network analysis in the study of regulome response to infection, resulting in new information on tick-pathogen interactions and potential targets for developing interventions for the control of tick infestations and pathogen transmission. Deciphering the precise nature of circuits that shape the tick regulome in response to pathogen infection is an area of research that in the future will advance our knowledge of tick-...

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 sought to detect and characterize hemoparasites among farms in acaricide-failure hotspots of central as compared to the acaricide-failure naïve areas in eastern Uganda. Nested PCR assays were performed to determine the prevalences of Babesia bovis, Babesia bigemina, Theileria parva, and Anaplasma marginale in cattle blood samples sourced from randomly selected farms. Randomly selected isolates were sequenced to determine the genetic diversity of the parasites using the following marker genes: B. bovis spherical body protein 4, B. bigemina rhoptry-associated protein 1a, T. parva 104 kDa microneme-rhoptry a...

Sibeko-Matjila, Milana Troskie, Ilse Vorster, Charles Byaruhanga, Marinda C. Oosthuizen Little is known about the occurrence of haemoparasites in cattle in communal grazing areas of Mungwi District of Northern Province, Zambia. Clinical signs and post mortem lesions are pathognomonic of mixed tick-borne infections especially babesiosis, anaplasmosis and East Coast fever. The main objective of this study was to screen selected communal herds of cattle for tick-borne haemoparasite...

These tick-borne diseases (TBD) cause considerable losses to Brazilian livestock breeders due to reduced productivity and treatment costs and pose an obstacle to the expa...

Ticks and the diseases they carry have long been recognized as health concerns, especially in the warmer months when ticks (and humans) are more active. Ticks wait on grass tips or shrubs to latch onto new hosts when they brush by. Most of the hosts are animals, but a few tick species do bite and feed on humans. While doing so, they can transmit bacteria and viruses through their saliva. But here’s what’s changing: Tick species are being found in a wider geographic range. The number of case reports of tick-borne illnesses is increasing. Scientists continue to identify new pathogens (bacteria and viruses that c...

Hewitt, Tyler A. Campbell, David Wester, Adalberto A. Pérez de León Cattle fever ticks (CFT), vectors of bovine babesiosis and anaplasmosis, were eradicated from the United States by 1943, but are frequently reintroduced from neighboring border states of Mexico via stray cattle and wildlife hosts including white-tailed deer (Odocoileus virginianus) (WTD) and nilgai antelope (Boselaphus tragocamelus).
