Approaching Universal Prenatal Detection of Significant Cardiovascular Malformations in Nevada.

Objective: To report our recent experience with prenatal detection of significant cardiovascular malformations (CVMs) in Nevada's state-wide maternal population receiving prenatal care.

Methods: We queried our databases for those with significant CVMs diagnosed pre- or postnatally between May 1, 2021, and April 30, 2024. We defined CVMs as those that required, would have required, or will likely require a therapeutic procedure in the first 12 months.

Snail coprophagy: the encounter filter, food preferences, and rat lungworm (Angiostrongylus cantonensis) prevalence.

Understanding the factors driving infection prevalence among host species is crucial for effective disease mitigation. Angiostrongylus cantonensis, the rat lungworm, causes neuroangiostrongyliasis and serves as an excellent model for studying infection dynamics across hosts. This study investigates the relative impact of encounter rates on A.

Unprecedented genetic variability of PFam54 paralogs among Eurasian Lyme borreliosis-causing spirochetes.

Lyme borreliosis (LB) is the most common vector-borne disease in the Northern Hemisphere caused by spirochetes belonging to the sensu lato (sl) complex. spirochetes circulate in obligatory transmission cycles between tick vectors and different vertebrate hosts. To successfully complete this complex transmission cycle, sl encodes for an arsenal of proteins including the PFam54 protein family with known, or proposed, influences to reservoir host and/or vector adaptation.

Stressed snails release (rat lungworm) larvae in their slime.

This study investigated the influence of stress on release of larvae from a snail host, . We subjected 140 infected, wild-caught to three stress-inducing treatments (heat, molluscicide, physical disturbance) and an unstressed control treatment for 24 h, after which larval presence and abundance in the slime were quantified by qPCR targeting the ITS1 region of the parasite's DNA, and compared among treatments. The significance of stress and host infection load on larval release was determined by generalized linear mixed models and permutation tests.
