Article Synopsis
- - Oocysts of Toxoplasma gondii found in cat feces can contaminate coastal waters, where they attach to algae and accumulate in bivalves; studies were conducted in the Kerguelen and Galapagos archipelagos to assess this contamination.
- - In the Galapagos, high cat density (142 per km) led to 15.38% of oysters testing positive for T. gondii, while in Kerguelen, lower cat density (1-3 per km) resulted in a higher percentage (40.83%) of mussels testing positive.
- - The research suggests that oocysts can spread several kilometers from their source and that environmental factors, like currents and kelp forests
Although Escherichia coli infections are common throughout the developing world, their prevalence patterns in space and over time are not well characterized. We used serial case control data collected from 16 communities in northwestern Ecuador between 2004 and 2010, to examine the prevalence of enteroinvasive E. coli (EIEC) and enterotoxigenic E.
