Human–Wildlife Interactions
Hunter harvest data suggest that feral hog (Sus scrofa) populations in western Louisiana are increasing, and population control in this region is complicated by the mixing of feral and domestic free-ranged hogs. Aggressive management may be warranted as feral and domestic hogs appear to be having unexpected effects on their ecosystem. We present the results of 3 recent investigations of genetic source-tracking to link waterborne bacteria with bacteria from feral hogs. We integrate our most recent findings with data regarding: (1) water quality in a watershed without hog management and (2) aquatic biota of the same watershed. Hog …

Human–Wildlife Interactions
Cattle are the main reservoir for human infection by pathogenic Escherichia coli and Salmonella enterica. To prevent entry of these food-borne pathogens into the human food chain, management factors at the farm level must be identified and controlled. External sources of contamination, such as birds, should be considered as potential sources of transmission over long distances. In this review, we focus on the epidemiology of infection by E. coli and S. enterica and the consequences of birds acting as disseminators of these pathogens at dairy farms in terms of cattle health and the subsequent effects on human health.
