Clostridium difficile: An Important Opportunistic Pathogen in Healthcare-Associated Infections

Soohyoun Ahn and Amarat H. Simonne

Healthcare-associated infections are infections that patients can get while receiving medical treatment in a healthcare facility. One opportunistic pathogen, Clostridium difficile, has been getting more attention in recent years because of its association with antibiotic use and a high death rate among the elderly.

Chagas Disease: A Review of Vector-Borne Transmission by Triatomine Bugs (Hemiptera, Reduviidae, Triatominae)

Bethany R. Eutsey, Cameron J. Jack, Shelley A. Whitehead, and Eva A. Buckner

Chagas disease is a potentially fatal, chronic disease caused by Trypanosoma cruzi, a protozoan parasite. It causes 6 to 8 million cases and 50,000 deaths each year. Humans and animals usually become infected with T. cruzi via triatomine bugs, also called kissing or conenose bugs, found only in the Americas. Disease transmitted by triatomine bugs generally occurs in rural areas of Mexico, Central America, and South America, but it is becoming more prevalent in non-endemic areas like the US as asymptomatic infected people move from rural to urban areas of Latin America and other regions.  In the US, approximately 300,000 people are currently infected with Chagas disease, 18,000 in Florida. Most if not all of them were infected elsewhere; local transmission of Chagas disease via triatomines in the US is rare. Awareness and understanding of Chagas disease are critical to detect and treat cases early. This publication is intended for anyone interested in learning more about Chagas disease.
