objective: cryptosporidiosis is a parasitic disease that is causing small protozoan genus cryptosporidum and transmission take place through fecal- oral by direct contact or indirectly through food or drink. the aim of this study was detection of anti-cryptosporidum parvum immunoglobulin igg, in newborn balb/c infected with c. parvum. materials and methods: oocysts of c. parvum were obtained f...

Cryptosporidium intestinal parasites have been detected in farmed pigs worldwide. Infections are usually asymptomatic with a low number of oocysts shed in pig feces. This makes the recognition of infection difficult or unsuccessful when microscopic methods are used. The aim of this study was molecular identification of Cryptosporidium species in pig herds raised in Poland with regard to the occ...

BACKGROUND Human Immunodeficiency Virus (HIV) infection leads to acquired immunodeficiency syndrome (AIDS) and major causes of morbidity and mortality of such patients are opportunistic infections caused by viral, bacterial, fungal and parasitic pathogens. OBJECTIVES To determine the magnitude of opportunistic and non-opportunistic intestinal parasitic infections among AIDS patients and HIV p...

SHELLFISH is one of the most important aquaculture products of Portugal yielding approximately 5,000 tons/yr (Direcção Geral das Pescas, www.dg-pescas.pt, July 2006). Seafood is an excellent natural resource which is common in the Portuguese diet and is in high demand by tourists. Some shellfish are consumed raw or undercooked. Several legal regulatory steps are in place that control processes ...

Cryptosporidum can be transmitted via water that is contaminated with human or animal faeces. There have been a number of documented outbreaks of cryptosporidiosis attributed to potable water, well water, spring water and surface water. Several outbreaks have also been associated with contaminated recreational water in swimming pools. Cryptosporidium are a particular risk in swimming pools beca...

Cryptosporidium parvum (C. parvum) infection is one of the main causes diarrhea in calves. The current study assessed role blood biomarkers (acute-phase proteins (APPs), procalcitonin, neopterin, cytokines, and oxidative stress pathogenesis, diagnosis, prognosis calves naturally infected with C. parvum. Fifty-seven calves, aged from 10 to 45 days, were detected positive for allotted into diseas...

CD154 is necessary for mice to clear a Cryptosporidium parvum infection, but whether this ligand has to be expressed on T cells with specificity for C. parvum has not been determined. We infected DO11.10 (ovalbumin specific) T-cell receptor transgenic mice that had been bred to a RAG(-/-) background with C. parvum and found that the infection was cleared within 6 weeks, while RAG(-/-) controls ...

Cryptosporidium parvum is an apicomplexan parasite that can cause serious watery diarrhea, cryptosporidiosis, in human and other mammals. C. parvum invades gastrointestinal epithelial cells, which have abundant glycosaminoglycans on their cell surface. However, little is known about the interaction between C. parvum and glycosaminoglycans. In this study, we assessed the inhibitory effect of sul...
