Sequence differences in the diagnostic target region of the oocyst wall protein gene of Cryptosporidium parasites [PDF]

, 2000
Nucleotide sequences of the Cryptosporidium oocyst wall protein (COWP) gene were obtained from Various Cryptosporidium spp. (C. wrairi, C. felis, C. meleagridis, C. baileyi, C. andersoni, C. muris, and C. serpentis) and C. parvum genotypes (human, bovine,

Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries

Pest Management Science, Volume 81, Issue 4, Page 1740-1751, April 2025.
Electrolyzed water treatments could have promising applications in the grapevine nursery process to prevent or reduce infections caused by fungal trunk pathogens on grapevine propagation material. Abstract BACKGROUND Grapevine producers demand solutions to control fungal trunk pathogens (FTPs) in nurseries.

Simplified methods for obtaining purified oocysts from mice and for growing Cryptosporidium parvum in vitro [PDF]

, 1996
Seven- to 8-day-old Arc/Swiss mice were infected with 100,000-120,000 Cryptosporidium parvum oocysts. At 8 days postinfection (PI) the jejunum, ileum, cecum, colon, and rectum were removed.

Transgenic selection and underlying mechanisms in apicomplexan parasites

The FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.

Cryptosporidium tyzzeri and Cryptosporidium pestis: Which name is valid? [PDF]

, 2012
The dispute on the validity of Cryptosporidium pestis and Cryptosporidium tyzzeri origins from the uncertainty on the identity of Cryptosporidium parvum described by Tyzzer in 1912 and the interpretation of the Principal of Priority of the International ...

PCR-RFLP analysis of the Cryptosporidium oocyst wall protein (COWP) gene discriminates between C. wrairi and C. parvum, and between C. parvum isolates of human and animal origin [PDF]

FEMS Microbiology Letters, 2006
Cryptosporidium wrairi was isolated from guinea pigs during a spontaneous outbreak of cryptosporidiosis. Despite the morphological and antigenic similarities to C. parvum, C. wrairi displayed a different host range and site of infection and may represent a separate species or sub-species.

First Metabolic Insights into Ex Vivo Cryptosporidium parvum-Infected Bovine Small Intestinal Explants Studied under Physioxic Conditions

Biology, 2021
The apicomplexan Cryptosporidium parvum causes thousands of human deaths yearly. Since bovines represent the most important reservoir of C. parvum, the analysis of infected bovine small intestinal (BSI) explants cultured under physioxia offers a ...

Distinct Microbial and Host Proteome Signatures Relate to Proteolytic Activity in Gingival Crevicular Fluid in an Exploratory Study of Patients With Periodontitis

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim Risk assessment tools for periodontitis lack sufficient precision to predict disease progression. The aim of this exploratory study was to evaluate proteolytic activity (PA) in gingival crevicular fluid in relation to clinically assessed progression risk, microbial community composition and host proteome. Materials and Methods Samples were

Transient transfection of Cryptosporidium parvum using green fluorescent protein (GFP) as a marker [PDF]

, 2009
Cryptosporidium parvum is a protozoan parasite that infects a variety of mammals. The parasite has been shown to harbor a dsRNA virus (CPV) and in the present study, we have developed a CPV transient transfection system for this parasite by using green ...
