Detection of high levels of congenital transmission of toxoplasma gondii in natural urban populations of mus domesticus [PDF]

, 2004
The relative importance of different transmission routes of Toxoplasma gondii has been a matter for debate. This ubiquitous parasite is generally thought to be transmitted by infective oocysts excreted by the definitive host, the cat.

Deposition of Cryptosporidium Oocysts in Streambeds [PDF]

Applied and Environmental Microbiology, 2006
ABSTRACT The transfer of Cryptosporidium oocysts from the surface water to the sediment beds of streams and rivers influences their migration in surface waters. We used controlled laboratory flume experiments to investigate the deposition of suspended Cryptosporidium parvum oocysts ...

Why, Immunologically, Housing‐Related Fungi and Endotoxins (and Other Chronic Pro‐Inflammatory Stressors) Risk Latent Tuberculosis Reactivation, Severe Asthma, and Translocating and Invasive Infections in Indigenous Communities in Canada

American Journal of Human Biology, Volume 38, Issue 4, April 2026.
ABSTRACT Type 1/M1/TH1 and type 3/M1/TH17 pro‐inflammatory switches are risks for latent Mycobacterium tuberculosis (Mtb) reactivation and ongoing infection transmission. This paper considers the heavy toll of reactivation risk in Indigenous communities in Canada and the chronic, everyday pro‐inflammatory stressors connected with type 3/M1/TH17 immune ...

Nanoparticle Lysis of Cryptosporidium Oocysts

Methods and Protocols
The extraction of DNA from Cryptosporidium oocysts is challenging due to the robust oocyst wall. Nanoparticles have been applied to disinfect Cryptosporidium oocysts; here, we demonstrate the utilisation of nanoparticles to disrupt the oocyst wall to enable sporozoite lysis and detection via PCR.

Endoparasite Prevalence in the Mountain Bongo (Tragelaphus eurycerus spp. isaaci) at Mount Kenya Wildlife Conservancy

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Parasite–host interactions influence the success of wildlife reintroductions. The mountain bongo (Tragelaphus eurycerus isaaci) is a critically endangered antelope found only in Kenya's montane forests, with fewer than 100 remaining in the wild. It is, therefore, imperative to re‐establish a viable, healthy, and self‐sustaining population in its native
