Burden of exposure to infectious bursal disease virus, infectious bronchitis virus, Newcastle disease virus, Mycoplasma gallisepticum, and intestinal parasites in introduced broiler chickens on the Galapagos.

Diseases in introduced broilers can possibly spill over to wild birds on the Galapagos. Knowledge about the current burden of exposure to pathogens in broilers on the Galapagos is very limited. The objective of the study reported here was to measure the burden of exposure to infectious bursal disease virus (IBDV), infectious bronchitis virus (IBV), Newcastle disease virus (NDV), Mycoplasma gallisepticum (MG), and intestinal parasites in a sample of broiler chickens on 13 farms on Santa Cruz Island and San Cristobal Island in July 2017.

Dog overpopulation and diagnosis of intestinal parasites on Santa Cruz Island, Galapagos 2016.

Dog overpopulation and diseases are hazards to native island species and humans on the Galapagos. The main objective of the study reported here was to estimate the observed human:dog ratio on Santa Cruz Island, Galapagos in September 2016. In addition, dog demographic data were used to model the expected annual dog population growth in the next 10 years.
