Prevalence of Spp. and Spp. Antigens and Antibodies in Housed and Grazing Korean Indigenous Cattle.
Vector Borne Zoonotic Dis
September 2024
Article Synopsis
- Infection with tick-borne pathogens in cattle can lead to serious health issues like anemia and growth retardation.
- This study tested both housed and grazing cattle in Korea for the presence of specific pathogens using antigen tests and analyzed antibody levels.
- The results indicated that while both types of cattle had similar antibody detection rates for one pathogen, grazing cattle had significantly higher antibody levels for the other pathogen, highlighting the distinct exposure risks associated with their environments.
Bovine hemolytic anemia has a negative impact on animal welfare and productivity due to its associated clinical symptoms. Hemolysis is generally known to cause reticulocytosis, increased indirect bilirubin, decreased concentration of haptoglobin, and increased lactate dehydrogenase. Additionally, tissue hypoperfusion due to concomitant anemia increases blood lactate concentration.

Lactate is closely associated with metabolic acidosis in diarrheic calves. However, there have been no reports on lactate concentrations in Korean indigenous (Hanwoo) calves, especially those with diarrhea.

To avert hundreds of thousands of unnecessary hospitalizations and deaths, adoption will need to be higher than it was in the autumn of 2022 or 2023, when less than one-fifth of Americans received booster vaccines. One approach to encouraging vaccination is to eliminate the friction of transportation hurdles.

Objectives: To identify the causative agents of TBP-induced haemolytic anaemia and determine haematological parameters that indicate haemolytic anaemia in grazing cattle.
Methods: Eighty-two Korean indigenous cattle (Hanwoo) were divided into two groups: grazing (n = 67) and indoor (n = 15) groups.
