Molecular evidence for the presence of Rickettsia Felis in the feces of wild-living African apes. [PDF]

PLoS ONE, 2013
Rickettsia felis is a common emerging pathogen detected in mosquitoes in sub-Saharan Africa. We hypothesized that, as with malaria, great apes may be exposed to the infectious bite of infected mosquitoes and release R.

Impacts of rodents in piggeries in Australia – review and pilot impact study

Pest Management Science, Volume 82, Issue 3, Page 2177-2189, March 2026.
Rodent impacts in Australian piggeries are under‐researched, with limited data on economic losses and control costs. A review and pilot study found average losses of AUD$100 000 annually. Key concerns include disease, damage, and control expenses.
