In this paper we report the occurrence of zoonotic species of Cryptosporidium (C. ubiquitum and C. parvum subtype IIaA15G2R1) and the host-specific Giardia duodenalis genotype E in a sheep farm from Brazil.

In this study, we identified Cryptosporidium species and genotypes present in dairy cattle in the central region of São Paulo state, Brazil. Fecal specimens were collected from 200 animals (100 calves and 100 cows) in ten dairy farms. Fecal samples were examined using microscopic examination (ME), enzyme immunoassay (EIA) and polymerase chain reaction (PCR).

Article Synopsis
- Giardia duodenalis is a common intestinal parasite found in humans and domestic animals, with a high prevalence reported in cattle worldwide, including 100% in certain herds.
- A study investigated the presence and genetic types of G. duodenalis in 200 dairy cattle across 10 farms in São Paulo, Brazil, using various diagnostic methods.
- The results showed an 80% prevalence across farm locations, with genotype E dominant in the infection cases; however, one zoonotic strain was also detected, indicating a potential public health concern.
