Unusual co-infection of severe malaria by Plasmodium vivax and dengue virus in Mexico.

Malaria and dengue fever are among the most common mosquito-borne diseases worldwide; however, reports of coinfection are rare. We present a case of severe malaria and dengue coinfection in a 16-yearold female patient presenting with fever, thrombocytopenia, pleural effusion, myopericarditis, and acute respiratory distress syndrome. Dengue infection was confirmed by the presence of immunoglobin M antibodies and nonstructural protein 1, while malaria was confirmed by the presence of Plasmodium vivax in thick and thin blood smears.

New report of Eratyrus cuspidatus Stål, 1859 (Hemiptera: Reduviidae: Triatominae) in the State of Campeche, Mexico.

Introduction: Triatomine bugs are vectors of Trypanosoma cruzi, the etiological agent of Chagas disease.

Methods: Triatomine bugs were collected and identified following established protocols. In addition, infection with T.

Feces from wild Triatoma dimidiata induces local inflammation and specific immune response in a murine model.

In endemic regions for Triatoma dimidiata the vector for Chagas disease, subjects can be in contact with insect`s feces several times through a lifetime. The triatomine’s digestive tract is colonized by diverse but few dominant genera of microorganisms. The immune responses to microbiota feces are poorly known in mammal hosts.

[Prevalence of dengue and leptospira in febrile patients of the general hospital of specialities in Mexico].

Among the infectious diseases characterized by a febrile picture are: dengue, leptospirosis, rickettsiosis and salmonellosis, among others. The objective of this study was to identify IgM antibodies against dengue and Leptospira in febrile patientes. The seropositivity for IgM antibodies to dengue was 34%; 26.
