Cryptosporidiosis worsened in mice on probiotics

(American Society for Microbiology) In an unexpected research finding infections with the intestinal parasite, Cryptosporidium parvum, worsened in mice that had been given a probiotic. The research was published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Abstract Cryptosporidiosis is one of the leading causes of moderate to severe diarrhea in children in low-resource settings. The therapeutic options for cryptosporidiosis are limited to one drug, nitazoxanide, which unfortunately has poor activity in the most needy populations of malnourished children and HIV infected persons. This paper describes the discovery and early optimization of a class of imidazopyridine-containing compounds with potential for treating Cryptosporidium infections. The compounds target the Cryptosporidium methionyl-tRNA synthetase (MetRS), an enzyme that is essential for protein synthesis. ...

is AD Abstract Cryptosporidium is a genus of single celled parasites capable of infecting a wide range of animals including humans. Cryptosporidium species are members of the phylum apicomplexa, which includes well-known genera such as Plasmodium and Toxoplasma. Cryptosporidium parasites cause a severe gastro-intestinal disease known as cryptosporidiosis. They are one of the most common causes of childhood diarrhoea worldwide, and infection can have prolonged detrimental effects on the development of children, but also can be life threatening to HIV/AIDS patients and transplant recipients. A variety of hosts can a...

Florin-Christensen, L. SchnittgerAbstractThe apicomplexan protozoan Cryptosporidium parvum is an important causative agent of diarrhea of neonatal bovines. Vaccination has been proposed as an advantageous strategy against cryptosporidiosis of calves since besides protection against disease it has also the potential to prevent dissemination of the infective oocysts into the environment. Antigens anchored to the parasite surface via gly...

Methods: A cross-sectional study was conducted among 50 HIV/AIDS patients with recurrent diarrhea. Questionnaires were administered to collect social and behavioral risk factors associated with Cryptosporidium and other opportunistic protozoan parasitic infections in HIV patien...

KeeganAbstractGiardia and Cryptosporidium are both waterborne parasites and leading causes of gastroenteritis. Although specimens from diarrhoeic patients are routinely examined for Cryptosporidium, they are often not examined for Giardia so many cases go undiagnosed. Since 2002, all faecal specimens in Central Lancashire have been tested for infection with Giardia and Cryptosporidium. The aim of this paper is to gain insight into the factors contributing to giardiasis and cryp...

This study aimed to establish an experimental infection of Cryptodporidium canis in canids. Infectivity and pathogenicity have been measured by evaluating the clinical status, pattern of oocyst excretion and histological examination. Results showed that C. canis was not infective for immunocompetent dogs or mice with severe combined immunodeficiency syndrome (SCID). Oocysts were first detected in the feces of immunosuppressed dogs on day 3 post-infection (p.i.), with levels peaking twice on days 10 and 17 p.i. during the patent period. cryptosporidial developmental stages were found in the duodenum and jejunum of dogs in h...

ou KT Abstract Cryptosporidiosis is a zoonotic disease caused by species in the genus Cryptosporidium. In young ruminants, Cryptosporidium parvum causes economically significant disease with mild to severe clinical signs and occasional death. The typical clinical course in animals aged 1 to 3 weeks old is acute diarrhoea. Currently there are no available treatments that are fully effective against cryptosporidiosis in either humans or animals. Therefore there is a critical need for the development of new therapeutic agents. We adapted two in vitro culture systems (HCT-8 and Caco-2 cell lines) for C. parvum infecti...

Rev Salud Publica (Bogota). 2018 Jan-Feb;20(1):138-143 Authors: Hernández-Gallo N, Hernández-Flórez LJ, Cortés-Vecino JA Abstract Cryptosporidiosis is a diarrheal disease (zoonotic) caused by the parasite Cryptosporidium, which infects the intestine. It occurs in humans and in different pets, farm and wild animals. Its role is underestimated and little is known about its epidemiology, due to the low interest it draws and the limited availability of diagnostic methods. The population health, both human and animal, is related to ...
