BACKGROUND Cryptosporidium spp. is prevalent globally, pigs are an important Cryptosporidium reservoir. In China, little data regarding rates of Cryptosporidium infections in pigs are available. The present study was therefore aimed at characterizing the distribution of Cryptosporidium species in pigs from two different cities, Shaoxing and Shanghai, from the Yangtze River delta.

background : although infection of dromedary camels with cryptosporidium spp. is rare in iran, it is considered a zoonotic threat to the keepers and herders of camels. thus we investigated the prevalence of cryptosporidium in these two hosts in yazd province, a semi-arid region in center of iran. methods : this study was conducted during 4 seasons (winter 2008, summer 2009, winter 2009 and summ...

The aims of this study were to determine the prevalence of Cryptosporidium spp in dairy cows in central Thailand and to investigate the genotype of Cryptosporidium spp in this population. A total of 200 fecal samples from dairy cows were collected and examined by the acid-fast staining technique and polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP). The prevalence of...

BACKGROUND Farm animals are usually suspected to transmit infections to humans. Domestic cavies (Cavia porcellus) are hosts to a variety of pathogens, some of which are zoonotic. Several parasites including the protozoa Giardia spp. and Cryptosporidium spp. may be causative agents of gastrointestinal disorders in domestic cavies and humans. The aim of the study was to investigate the occurrence...

Cryptosporidium and Giardia are 2 protozoan parasites responsible for waterborne diseases outbreaks worldwide. In order to assess the prevalence of these protozoans in drinking water samples in the northern part of Portugal and the risk of human infection, we have established a long term program aiming at pinpointing the sources of surface water, drinking water, and environmental contamination,...

Cryptosporidium is considered to be one of the indicators of environmental contamination and water quality (Garcia 2001, Fayer 2004, Ramirez & Sreevatsan 2006). At the present time the presence of this parasite has been recorded on all the continents, including Antarctica (Fredes et al. 2007a). Since the first description of Cryptosporidium by Tyzzer in 1912, 14 new species of this parasite hav...

Early studies assumed that all infections in mammals, including humans, were caused by the parasite Cryptosporidium parvum. Recent studies using molecular biologic tools and hostspecificity studies indicate that ca...

In a previous study, we have developed several chicken monoclonal antibodies (mAbs) against Eimeria acervulina (EA) in order to identify potential ligand molecules of Eimeria. One of these mAbs, 6D-12-G10, was found to recognize a conoid antigen of EA sporozoites and significantly inhibited the sporozoite invasions of host T lymphocytes in vitro. Furthermore, some of these chicken mAbs showed c...

The study determined the relative importance of Escherichia coli, E. coli O157, Salmonella spp., Clostridium spp., rotavirus, Cryptosporidium spp., and Strongyloides westeri in foal (diarrhoeic and non-diarrhoeic) available for sampling during the foaling season of 2010 and determined their sensitivity to antimicrobial agents. A cross-sectional study was conducted on 164 foals (9 diarrhoeic and...

Parasites are important productionlimiting diseases in livestock farming. Their proper treatment and control requires knowledge of their presence, epidemiology, and diagnostics. We investigated the presence of the GI parasites in pooled herd faecal samples from the islands Saaremaa (n=21), Hiiumaa (n=18), and Vormsi (n=7), collected in 2011–2012. The samples were investigated microscopically af...
