Comparative genomics of reveals the emergence of an outbreak-associated population in Europe and its spread to the United States.

The zoonotic parasite is a global cause of gastrointestinal disease in humans and ruminants. Sequence analysis of the highly polymorphic gene enabled the classification of isolates into multiple groups (e.g.

Cryptosporidium species and subtypes identified in human domestic cases through the national microbiological surveillance programme in Sweden from 2018 to 2022.

Background: The intestinal protozoan parasite Cryptosporidium is an important cause of diarrheal disease worldwide. A national microbiological surveillance programme was implemented in Sweden in 2018 in order to increase knowledge of the molecular epidemiology of human cryptosporidiosis to better understand transmission patterns and potential zoonotic sources. This article summarises the results of the first five years of the surveillance programme.

Extensive testing of a multi-locus sequence typing scheme for Giardia duodenalis assemblage A confirms its good discriminatory power.

Background: The flagellated parasite Giardia duodenalis is a major and global cause of diarrhoeal disease. Eight genetically very distinct groups, known as assemblages A to H, have been recognized in the G. duodenalis species complex, two of which (assemblages A and B) infect humans and other mammalian hosts.

Water quality modelling and quantitative microbial risk assessment for uMsunduzi River in South Africa.

South African rivers generally receive waste from inadequate wastewater infrastructure, mines, and farming activities, among others. The uMsunduzi River in KwaZulu-Natal, South Africa, is among these recipients with recorded poor to very poor water quality. To identify parts of the uMsunduzi River that are polluted by Cryptosporidium and Escherichia coli (E.

Sarcoptic mange in the wild boar, , in Sweden.

Sarcoptic mange caused by has been present in the Swedish red fox () population since the 1970s. The disease has been described in other Swedish wildlife species, but not in the wild boar, , until 2009. Single cases of sarcoptic mange have been diagnosed the last years in the expanding population of wild boar.
