PUBLICATIONSPeer-Reviewed Research

Our lab regularly publishes our research findings in peer-reviewed scientific journals. "Peer-review" means that other scientists and experts have critically reviewed our methods, findings, and conclusions and found them to be well-done and trustworthy. Publishing in peer-reviewed journals also ensures that our research findings will be permanently available to future generations interested in understanding our lab's work. Here, we have compiled a list of our current publications, including a brief summary, as well as the link to the article.

Curtis-Robles R, Wozniak EJ, Auckland LD, Hamer GL, Hamer SA. 2015. Combining public health education and disease ecology research: Using citizen science to assess Chagas disease entomological risk in Texas. PLoS Neglected Tropical Diseases 9(12): e0004235.

From May 2013 to December 2014, a total of 1,980 kissing bugs were submitted to our program, mostly collected from dog kennels and outdoor patios. These bugs allow insight into a cross-section of bugs of high epidemiological and veterinary relevance. Citizen submissions of kissing bugs peaked in June-July and showed 63.3% infection prevalence with the Chagas parasite.

Tenney, TD, Curtis-Robles R, Snowden KF, Hamer SA. 2014. Shelter dogs as sentinels for Trypanosoma cruzi transmission across Texas, USA. Emerging Infectious Diseases 20(8): 1323-1326.

We tested high-risk shelter dogs from seven shelters across Texas. We found that 8.8% of dogs had evidence of exposure to the Chagas disease parasite, showing that dogs from diverse areas of Texas are at risk.

Comeaux J, Curtis-Robles R, Lewis BC, Cummings KJ, Mesenbrink BT, Leland BR, Bodenchuk MJ, Hamer SA. 2016. Survey of feral swine (Sus scrofa) infection with the agent of Chagas disease (Trypanosoma cruzi) in Texas, 2013-2014. Journal of Wildlife Diseases 52(3): 627-630.

Feral hogs are an abundant and wide-spread nuisance species across the southern US. We tested feral hogs from across Texas and found evidence of the Chagas parasite in 6% of the hogs.

Curtis-Robles R, Lewis BC, Hamer SA. 2016. High Trypanosoma cruzi infection prevalence associated with minimal cardiac pathology among wild carnivores in central Texas. International Journal for Parasitology: Parasites and Wildlife 5(2): 117-123.

We tested bobcats, coyotes, foxes, and raccoons for evidence of the Chagas parasite. We found 12-14% of bobcats, coyotes, and foxes were infected, and 70% of raccoons with infected. Raccoons may be very important to the maintenance of the Chagas parasite in Texas.

Hodo CL, Goodwin CC, Mayes BC, Mariscal JA, Waldrup KA, Hamer SA. 2016. Trypanosome species, including Trypanosoma cruzi, in sylvatic and peridomestic bats of Texas, USA. Acta Tropica 164: 259-266.

We tested insectivorous bats from across Texas and found 0.17% of bats were infected with the Chagas parasite. This finding is the first report of the Chagas parasite in a bat in the US.

Hodo CL, Bertolini NR, Bernal JC, VandeBerg JL, Hamer SA. 2017. Lack of Trypanosoma cruzi infection in urban roof rats (Rattus rattus) at a Texas facility housing naturally infected nonhuman primates. Journal of the Association for Laboratory Animal Science 56(1): 57-62

We sampled roof rats from a non-human primate facility in Texas. None of the rats we tested were positive for the Chagas parasite, suggesting that this species of rat is likely not a source of infection at this facility.

Bryan LA, Hamer SA, Shaw S, Curtis-Robles R, Auckland LD, Hodo CL, Chaffin K, Rech RR. 2016. Chagas disease in a Texas horse with neurologic deficits. 216: 13-17.

We were involved in a study of a 10-year old Texas horse with neurologic disease, which found the Chagas parasite in the spinal cord of the horse. This was the first case study of Chagas disease in a horse in the US.

Curtis-Robles R, Zecca IB, Roman-Cruz V, Carbajal ES, Auckland LD, Flores I, Millard AV, Hamer SA. 2017. Trypanosoma cruzi (agent of Chagas disease) in sympatric human and dog populations in colonias of the Lower Rio Grande Valley of Texas. The American Journal of Tropical Medicine and Hygiene 96(4): 805-814.

We sampled people and dogs living in medically-underserved colonias along the Texas-Mexico border. We found 1.3% of people and 19.6-31.6% of dogs were infected with the Chagas parasite. Kissing bugs collected by residents of the colonias were found to have fed on dog, human, and raccoon blood; one bug was infected with the Chagas parasite.
