Cryptosporidium parvum oocysts and Clostridium perfringens spores are very resistant to chlorine and other drinking-water disinfectants. Clostridium perfringens spores have been suggested as a surrogate indicator of disinfectant activity against Cryptosporidium parvum and other hardy pathogens in water. In this study, an alternative disinfectant system consisting of an electrochemically produce...

The Giardia and Cryptosporidium species are widespread and frequent diarrhea-related parasites affecting humans and other mammalian species. The prevalence of these parasites in Mongolia is currently unknown. Therefore, we performed molecular analyses of G. duodenalis and C. parvum in stool samples from 138 patients hospitalized with diarrhea in Mongolia using nested polymerase chain reaction (...

A survey in olive orchards Istria (Croatia) was carried out from 2016 to 2018 investigate pathogens potentially associated with decline and dieback. In nine orchards, canker-like symptoms were recorded on trunks branches. Six fungal species isolated cankers: Geosmithia sp., Diaporthe Diatrype stigma, Diplodia seriata, Neofusicoccum parvum, Pseudophaeomoniella oleae. Pathogenicity tests conducte...

The aim of this study was to evaluate the serum concentration iron, copper and zinc in neonatal lambs naturally infected with Cryptosporidium parvum, determine relations between these trace elements clinical severity disease. For purpose, parvum (n=27) healthy control (n=10) were evaluated. Faecal consistency, willingness rise, stance when up, appetite, attitude, hydration status scored within ...

Antibiotic resistance in Ureaplasma urealyticum/Ureaplasma parvum and Mycoplasma hominis is an issue of increasing importance. However, data regarding the susceptibility and, more importantly, the clonality of these organisms are limited. We analyzed 140 genital samples obtained in Bern, Switzerland, in 2014. Identification and antimicrobial susceptibility tests were performed by using the Myco...

The performance of a new commercial PCR-enzyme-linked immunosorbent assay (ELISA) (Cryptodiag; Bio Advance, France) for the diagnosis of cryptosporidiosis and the identification of Cryptosporidium hominis and C. parvum from stool samples was examined. This test is based on PCR amplification of Cryptosporidium DNA extracted from stools, followed by an ELISA based on hybridization with Cryptospor...

BACKGROUND Epidemiologic studies show a strong association between Ureaplasmas and urogenital tract disease in humans. Since healthy humans can be colonized with Ureaplasmas, its role as a pathogen remains controversial. In order to begin to define the role of the host in disease, we developed a rodent model of urinary tract infection (UTI) using Fischer 344 (F344) rats. Animals were inoculated...

Cryptosporidium parvum, which is resistant to chlorine concentrations typically used in water treatment, is recognized as a significant waterborne pathogen. Recent studies have demonstrated that chlorine dioxide is a more efficient disinfectant than free chlorine against Cryptosporidium oocysts. It is not known, however, if oocysts from different suppliers are equally sensitive to chlorine diox...

Ureaplasma sp. infection in neonates and adults underlies a variety of disease pathologies. Of the two human Ureaplasma spp., Ureaplasma parvum is clinically the most common. We have developed a high-resolution melt (HRM) PCR assay for the differentiation of the four serovars of U. parvum in a single step. Currently U. parvum strains are separated into four serovars by sequencing the promoter a...

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...
