Opis:
Parasitic protozoans of the Cryptosporidium genus are intracellular intestinal parasites of mammals, causing cryptosporidiosis. Clinically, cryptosporidiosis manifests as chronic diarrhoea. Individuals with immune disorders, including those with neoplasms, are at risk of symptomatic invasion.The aim of the study was the evaluation of Cryptosporidium sp. prevalence in patients with diagnosed colorectal cancer.Material and methods. The studied group encompassed 87 patients with diagnosed colorectal cancer, undergoing surgery at the Department of General and Oncological Surgery, Pomeranian Medical University, in the years 2009-2010. Immunoenzymatic tests for Cryptosporidium sp. on faeces samples were performed with the use of commercial test kit, ProSpecT®Cryptosporidium Microplate Assay (Remel Inc).Results. The presence of Cryptosporidium sp. was found in 12.6% of studied patients with colorectal cancer. The performed statistical analysis did not reveal any correlation between Cryptosporidium sp. infection and gender, age, neoplasm advancement stage as per Astler-Coller scale, neoplasm differentiation grade, or neoplastic tumour localisation in relation to the splenic flexure.Conclusions. There was found high prevalence of Cryptosporidium sp. in patients with colorectal cancer. It was comparable to the prevalence reported for patients with immune deficiency.

Opis:
The main aim of the study was to determine the risk of two selected zoonosis infections caused by Giardia duodenalis and Cryptosporidium spp. among an occupational group of veterinarians in Poland. Two hundred and ninety-seven samples of stool were tested for the presence of Giardia cysts and Cryptosporidium oocysts using Direct Fluorescent Assay (DFA). There were no positive results for Cryptosporidium. The presence of Giardia cysts was found in two samples of faeces (0.67%). The risk with regard to the parasites Giardia duodenalis and Cryptosporidium spp. seems to be low among the group of veterinarians.

Opis:
To study the occurrence of Cryptosporidium infection in laboratory rats (Rattus norvegicus) raised for experimental usage, 134 faecal samples were obtained from two rearing houses in Ibadan and examined for the presence of Cryptosporidium oocyst using the modified acid fast staining technique. Cryptosporidium species in 2 samples positive for microscopy were further characterized by a nested polymerase chain reaction (PCR) amplifying the 18S rRNA gene. Two of 134 samples were positive for the Cryptosporidium oocysts. Sequencing of the small-subunit rRNA amplicons identified the species in the two PCR positive samples as Cryptosporidium andersoni and Cryptosporidium rat genotype. These findings showed that laboratory rat is a potential reservoir for diverse Cryptosporidium species and suggests that laboratory rats should be screened for Cryptosporidium infection prior to experiments, especially where pathogen free animals are not available. This the first report to identify Cryptosporidium species infecting laboratory rats in Nigeria.

Opis:
Long term field studies and laboratory experiments demonstrated that synanthropic filth flies can mechanically transmit infectious oocysts of Cryptosporidium parvum, an anthropozoonotic protozoan parasite which significantly contributes to the mortality of immunocompromised or immunosuppressed people. C. parvum oocysts are acquired from unhygienic sources, and can pass trough fly gastrointestinal track without alteration of their infectivity and can be subsequently deposited on visited surfaces. Transmission of the oocysts by adult flies occurs via: (1) mechanical dislodgement from the exoskeleton; (2) fecal deposition; and (3) regurgitation, i.e., vomits. Filth flies can cause human or animal cryptosporidiosis via deposition of infectious oocysts on the visited foodstuf, and the biology and ecology of synanthropic filth flies indicate that their potential for mechanical transmission of C. parvum is high.

Opis:
Cryptosporidium parvum, an Apicomplexan parasite, is an important cause of diarrheal disease, especially in immunodeficient hosts. Nevertheless, there is no entirely successful therapeutic agent against cryptosporidiosis to date. Hence, this study aims to test the potential prophylactic and therapeutic effect of Camellia sinensis (green tea extract) in dexamethasone immunosuppressed mice versus the nowadays used drug, Nitazoxanide (NTZ). Parasitological and molecular methods were used to characterize Cryptosporidium oocysts before infection. Fifty bred female Swiss Albino mice were divided into 5 groups; group I (GI)(GTP): immunosuppressed and prophylactically treated with green tea extract for 5 days prior to infection, group II (GII)(GTT): immunosuppressed, infected with Cryptosporidium parvum and treated with green tea extract, group III (GIII)(NT): immunosuppressed, infected and treated with NTZ, group IV (GIV)(PC): immunosuppressed and infected (Positive control), group V (GV)(NC): immunosuppressed and non-infected (Negative control). Furthermore, parasitological examination for oocysts in the stool, and histopathological examination for the small intestine and liver specimens were performed for the study groups. Cryptosporidium oocysts used for induction of infection proved to be Cryptosporidium parvum genotype 2. Moreover, a significant oocyst reduction in fecal samples correlated with an improvement of histopathological changes in the small intestinal and liver tissues in GI(GTP), GII (GTT) and GIII(NT) groups. Besides, the GII(GTT) group showed the best improvement in parasitological and histopathological parameters among the test groups. This study revealed that Camellia sinensis (green tea extract) has potential activity against cryptosporidiosis and could serve as a promising prophylactic and therapeutic anti-cryptosporidial agent.

Opis:
Introduction and objectives. The parasite Cryptosporidium spp. is an intracellular protozoa which has a broad range of hosts and zoonotic potential. It presents a serious health risk for agricultural workers and veterinarians. The aim of the study was to identify the species and subtypes of Cryptosporidium occurring in a veterinary student who came into contact with calves on a farm. Materials and method. The Ziehl-Neelsen staining technique was employed to confirm the presence of Cryptosporidium oocysts. ELISA test was applied to detect coproantigen in faecal specimens. Nested PCR was used to amplify a small ribosomal subunit (SSU rRNA) and sequencing of the GP60 gene served to identify the zoonotic subtypes. Results. The nested PCR allowed to confirm the C. parvum species; subsequently, the IIdA15G1 zoonotic subtype was identified. Conclusion. This is the first confirmed case in Slovakia of human cryptosporidiosis caused by the unique subtype IIdA15G1.
