Simplified Linear Dose‐Response Models for Low‐Dose QMRAs

AWWA Water Science, Volume 8, Issue 5, September/October 2026.
ABSTRACT This study analyzes widely used dose‐response (DR) models from potable reuse quantitative microbial risk assessments (QMRAs) to identify the low‐dose ranges where the log10‐transformed probability of infection and pathogen dose exhibit a linear relationship.

Cryptosporidium Occultus in Disguise

Journal of Microbiological Methods
As data accumulate in GenBank, the difficulties of delineating species of Cryptosporidium based on nuclear small subunit ribosomal RNA (ssu rRNA) gene information alone becomes increasingly evident. Here, we summarize currently available evidence suggesting that several ssu rDNA sequences primarily referred to as Cryptosporidium suis (some of them from

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,

Molecular characterization of Cryptosporidium isolates from humans and other animals using random amplified polymorphic DNA analysis [PDF]

, 1995
Genetic variation in 25 Cryptosporidium isolates was analyzed using the random amplified polymorphic DNA (RAPD) technique. Simple reproducible polymorphisms were generated (using five primers) from Cryptosporidium DNA that was free of contaminating ...

High‐Content CRISPR Screening: Methods and Applications

MedComm, Volume 7, Issue 9, September 2026.
High‐content CRISPR screening represents a paradigm shift in functional genomics, moving beyond traditional survival‐based readouts to enable multidimensional mapping of genotype–phenotype relationships. This review systematically outlines the methodological evolution of this approach, detailing advances in perturbation modalities, delivery systems ...

Cryptosporidium, Enterocytozoon, and Cyclospora Infections in Pediatric and Adult Patients with Diarrhea in Tanzania. [PDF]

, 1999
Cryptosporidiosis, microsporidiosis, and cyclosporiasis were studied in four groups of Tanzanian inpatients: adults with AIDS-associated diarrhea, children with chronic diarrhea (of whom 23 of 59 were positive [+] for human immunodeficiency virus [HIV]),

Multiplex PCR to Diagnose Gastrointestinal Infections: Key Limitations in Interpretation

United European Gastroenterology Journal, Volume 14, Issue 7, September 2026.
ABSTRACT Multiplex polymerase chain reaction (PCR) panels are increasingly used for the evaluation of acute diarrhea, providing rapid and sensitive detection of a broad range of enteric pathogens. However, their widespread adoption has created important interpretive challenges for clinicians.
