Multiple urogenital and ocular anomalies occurring in a litter of guinea pigs

Abstract

Following an outbreak of proliferative pneumonia in a guinea pig breeding colony and subsequet treatment with Tylan, a litter of guinea pigs was found to have multiple urogenital and ocular anomalies. Subsequent mating of the parents produced no abnormal offspring. Chromosome typing on the litter showed no abnormalities. A review of normal developmental anatomy and reports of similar anomalies was made in order to elucidate the pathogenesis of the multiple anomalies seen. It was concluded that the teratogenic effect occurred after the formation of the masonephros. The teratogen may have been an infectious agent or the drug Tylan.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.

Pontocerebellar Hypoplasia

Pontocerebellar hypoplasias are a group of neurodegenerative autosomal recessive disorders with prenatal onset, atrophy or hypoplasia of the cerebellum, hypoplasia of the ventral pons, microcephaly, variable neocortical atrophy and severe mental and motor impairments. Here is the latest research on pontocerebellar hypoplasia.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain.
