Cryptosporidiosis is a worldwide diarrheal disease caused by the protozoan . The primary symptom is diarrhea, but patients may exhibit different symptoms based on the species of the parasite they are infected with. Furthermore, some genotypes within species are more transmissible and apparently virulent than others.

Diagnosis of protozoa diarrhoea in Campylobacter patients increases markedly with molecular techniques.

Cryptosporidium and Giardia are major causes of diarrhoea globally, and two of the most notified infectious diseases in New Zealand. Diagnosis requires laboratory confirmation carried out mostly via antigen or microscopy-based techniques. However, these methods are increasingly being superseded by molecular techniques.

Uncovering the genetic diversity of Giardia intestinalis in isolates from outbreaks in New Zealand.

Background: Giardia intestinalis is one of the most common causes of diarrhoea worldwide. Molecular techniques have greatly improved our understanding of the taxonomy and epidemiology of this parasite. Co-infection with mixed (sub-) assemblages has been reported, however, Sanger sequencing is sometimes unable to identify shared subtypes between samples involved in the same epidemiologically linked event, due to samples showing multiple dominant subtypes within the same outbreak.

First report of novel assemblages and mixed infections of Giardia duodenalis in human isolates from New Zealand.

High-Yield Purification of Giardia intestinalis Cysts from Fecal Samples.

Giardia is an enteric protozoan parasite that causes gastroenteritis in all classes of vertebrates. It is ranked among the leading causes of death in children under 5 years of age. Giardiasis affects approximately 280 million people worldwide annually, a situation exacerbated by the low availability of effective treatments and the lack of a vaccine.
