Sung, H., & Tellez, M. (2016). Spatial variation of parasite infracommunities in the American alligator (Alligator mississippiensis). The Southwestern Naturalist, 61(4), 324–329.
Parasites were harvested from lungs and gastrointestinal tracts of Alligator mississippiensis from Texas. We compared our results with previous parasitism findings from alligators harvested in 2011 in Louisiana and Florida. Florida alligators exhibited the greatest pentastomid prevalence and mean intensity and illustrated higher stomach prevalence and intensity than other locations. Prevalence and mean intestinal parasitism of western Louisiana alligators differed significantly from other locations. Collectively, 14 species of trematodes and 7 species of nematodes were identified among Texas, Louisiana, and Florida. Differences in the parasite infracommunity structure across the alligators' geographic range likely reflects abiotic-biotic variation among the hosts' environment.
