Abstract
Fecal specimens were obtained from mature milking cows on farms in Vermont, New York, Pennsylvania, Maryland, Virginia, North Carolina, and Florida. Polymerase chain reaction (PCR)-positive specimens for Enterocytozoon bieneusi were found in 24 of 541 cows examined (4.4%) and on 12 of 14 farms. The prevalence of E. bieneusi varied considerably from farm to farm, with the lowest prevalence (2.3%) on FL-2 and the highest prevalence (12.5%) on VT-2. None of the cows exhibited signs of diarrhea. All PCR-positive specimens were sequenced to determine the genotype of E. bieneusi. Five genotypes were identified. Three were identified as cattle-specific genotypes previously reported as BEB1, BEB2, and BEB4, and two new genotypes, BEB 6 and BEB7, were found. None have been reported to infect humans.Entities:
