Abstract

Cryptosporidium parvum DNA from 175 neonatal calves on 16 farms in eight eastern states in the United States was subtyped by sequence analysis of the 60-kDa glycoprotein gene to determinate the parasite genetic diversity. Six subtypes of the IIa subtype family were found. Subtype IIaA15G2R1, which...

Abstract

The prevalence of Cryptosporidium species in 1-2-year-old heifers was determined for 571 animals on 14 dairy farms in seven states on the East Coast of the United States. A fecal specimen collected directly from each heifer was processed to concentrate oocysts that were then examined by polymerase...

Abstract

To determine the prevalence of Giardia genotypes in pre-weaned dairy calves, faecal samples were collected from a minimum of 18, 1-7-week-old dairy calves per farm on two farms each in the states of Vermont, New York, Pennsylvania, Maryland, Virginia, North Carolina, and Florida. Samples cleaned of ...

Abstract

To investigate the in vivo role of CD4+ T lymphocytes during acute anaplasmosis, thymectomized calves were selectively depleted of CD4+ T lymphocytes by treatment with anti-CD4 monoclonal antibody (MAb) and were then infected with the Florida (USA) strain of Anaplasma marginale in two sequential...

Abstract

Performance of Angus cows and calves was compared between 2 methods of bahiagrass (Paspalum notatum) grazing management, rotational stocking and continuous intensive stocking, where stocking rate was varied by adjusting available pasture area as forage growth rate changed during the growing season. ...
