This study was carried out to assess the potential of animals, used for teaching and research, as a source of Cryptosporidium infection for students and staff of a University in Nigeria. Faecal samples from 185 animals reared on the teaching and research farm were collected and examined for Cryptosporidium spp. antigens by the use of an enzyme-linked immunosorbent assay (ELISA). From all the sa...

  Cryptosporidium species are one of the most common causes of gastrointestinal infection in humans around the world. This study has aimed to investigate the hyper variable region of the 18S rRNA gene in Cryptosporidium for exact parasite identification .   DNA was extracted from 26 fecal samples from which initially Cryptosporidium oocysts were identified by Ziehl-Neelsen acid-fast , Auramine ...

The prevalence of Cryptosporidium infection among lambs and goat kids in Serbia was examined. The animals were grouped according to age, i.e., up to 30 days and from 31 to 90 days. The infection was diagnosed using three coprological procedures. Sheather’s sugar flotation was employed to determine the concentration of oocysts. Modified Ziehl-Neelsen technique and modified Kinyoun technique were...

We report a case of severe human cryptosporidiosis caused by Cryptosporidium tyzzeri and C. parvum with an unusually high frequency of liquid stools. Wild mice were the most likely source of infection, demonstrating the potential for wild-mouse-borne Cryptosporidium to infect humans and highlighting the health risks associated with synantropic rodents.

Cryptosporial and bacterial co-infection is reported in a budgerigar with clinical manifestations of septicemia and respiratory tract infection. Microscopically large number of round to oval 2-5μm cryptosporidial organisms were found to be lodged on the parabronchial epithelial cells of the respiratory tract. The bacterial colonies were seen around the parabronchial spaces of the lung tissue. I...

Abstract Surveillance for soil-transmitted helminths, strongyloidiasis, cryptosporidiosis, and giardiasis was conducted in Mississippi, USA. PCR performed on 224 fecal samples all helminths 370 only Necator americanus Strongyloides stercoralis identified 1 S. infection. Seroprevalences were 8.8% Toxocara, 27.4% Cryptosporidium, 5.7% Giardia, 0.2% parasites.

BACKGROUND Cryptosporidium and Giardia duodenalis are gastro-intestinal parasites that infect human and animals worldwide. Both parasites share a broad host range and are believed to be zoonosis. The aim of this study was to identify the species of Cryptosporidium and assemblages of G. duodenalis in lambs and to elucidate their role in zoonotic transmission. RESULTS A total of 389 fecal sampl...

Parasitic infection is uncommon in the United States, but surveys suggest that physicians test when the presence of parasites is unlikely and fail to order appropriate testing when suspicion is high. Numerous studies confirm that immunoassays are more sensitive for Giardia and Cryptosporidium detection, but our experience was that physicians preferentially used ovum and parasite examination (O&...

Cryptosporidium, formerly classified to subclass Coccidia has been relocated to genus Gregarina which includes free living stages, enabling host-free multiplication and therefore may constitute an additional risk factor for human infection. The free stage of this parasitic protozoon, the oocyst, is incredibly durable under various environmental conditions, elucidating its long survival potentia...

A study conducted at the Tampin Drug Rehabilitation Center in Malaysia established a high prevalence (23%) of asymptomatic carriers of Cryptosporidium among exposed HIV positive intravenous drug users (IVDUs). A majority of them were young adults and among the ethnic groups, the Malay HIV positive inmates had the highest prevalence of Cryptosporidium infection.
