Prevalence of Cryptosporidium spp. oocysts in dairy calves in Kerman, southeastern Iran
Faecal samples from 291 dairy calves from 10 dairy herds in Kerman were examined to investigate theprevalence of Cryptosporidium infection. Cryptosporidium spp. oocysts were identified by using themodified Ziehl-Neelsen staining technique in 63 (21.65%) calves. Calves were grouped according to theirage as follows:
متن کاملMultilocus fragment typing and genetic structure of Cryptosporidium parvum Isolates from diarrheic preweaned calves in Spain.
A collection of 140 Cryptosporidium parvum isolates previously analyzed by PCR-restriction fragment length polymorphism (PCR-RFLP) and sequence analyses of the small-subunit (SSU) rRNA and 60-kDa glycoprotein (GP60) genes was further characterized by multilocus fragment typing of six minisatellite (MSB and MS5) and microsatellite (ML1, ML2, TP14, and 5B12) loci. Isolates were collected from dia...
متن کاملPrevalence and Genetic Characterization of Cryptosporidium Species in Dairy Calves in Central Ethiopia
The burden of cryptosporidiosis due to Cryptosporidium parvum is well documented in HIV-positive patients in Ethiopia. However, the role of animals in zoonotic transmission of the disease is poorly understood. The aim of this study was to determine the prevalence and genotypes of Cryptosporidium species in dairy calves; to assess the role of cattle in zoonotic transmission in central Ethiopia. ...
متن کاملDetection of Bovine Coronavirus in Healthy and Diarrheic Dairy Calves
BACKGROUND BCoV is identified in both healthy and diarrheic calves, complicating its assessment as a primary pathogen. OBJECTIVES To investigate the detection rates of bovine coronavirus (BCoV) in feces of healthy and diarrheic calves and to describe the usefulness of a pancoronavirus reverse transcriptase (RT) PCR (PanCoV-RT-PCR) assay to identify BCoV in samples of diarrheic calves. ANIMA...
متن کاملCryptosporidium spp., comparative diagnosis and geospatial distribution in diarrheic calves from dairy farms, Valdivia, Chile
Objective. To determine the Cryptosporidium spp. infection frequency by using Ziehl-Neelsen and Auramine stains on samples obtained from diarrheic calves from milking farms of the Valdivia province. To compare both diagnostic tests and to determine the geospatial distribution of the infections caused by this protozoan. Materials and methods. 221 fecal samples of diarrheic calves of 24 milking f...
