Serological tests reveal significant cross-reactive human antibody responses to Zika and Dengue viruses in the Mexican population.

Zika virus (ZIKV) is a mosquito-borne flavivirus that has caused recent large outbreaks in the Americas. Given its association with severe congenital defects including microcephaly, distinguishing infections caused by ZIKV from those caused by dengue virus (DENV) is of primordial importance. The objectives of this study were to evaluate the recombinant proteins rEIII-ZIKV (Envelope protein domain III) and rNS1ß-leader-ZIKV (non-structural protein 1) for the serological diagnosis of ZIKV in the Mexican population.

Shared and organism-specific host responses to childhood diarrheal diseases revealed by whole blood transcript profiling.

Globally, diarrheal diseases are a leading cause of death in children under five and disproportionately affect children in developing countries. Children who contract diarrheal diseases are rarely screened to identify the etiologic agent due to time and cost considerations associated with pathogen-specific screening and hence pathogen-directed therapy is uncommon. The development of biomarkers to rapidly identify underlying pathogens could improve treatment options and clinical outcomes in childhood diarrheal diseases.

Incidence, clinical presentation, and antimicrobial resistance trends in Salmonella and Shigella infections from children in Yucatan, Mexico.

Background: Salmonella and Shigella cause significant morbidity and mortality among children worldwide. Increased antimicrobial resistance results in greater burden of disease.

Materials And Methods: From 2005 to 2011, Salmonella and Shigella isolates collected from ill children at a major hospital in Yucatan, Mexico, were subjected to serotyping and antimicrobial susceptibility testing by disk diffusion and agar dilution.

Antimicrobial-resistant Campylobacter in the food chain in Mexico.

We describe prevalence and antimicrobial susceptibility results for thermophilic Campylobacter isolates collected from humans, food, and food-animals in an integrated food chain surveillance network in Mexico. From 2003 to 2006, stool samples were collected from children with diarrhea at state sentinel hospitals. Concurrently, fecal samples from asymptomatic children in kindergartens, as well as raw chicken, pork and beef from retail outlets, and food-animal intestines from slaughterhouses were all collected in 65 cities from four different states.

Burden and transmission of zoonotic foodborne disease in a rural community in Mexico.

Background: The foodborne transmission and human health impact of Salmonella and Campylobacter infections have rarely been evaluated at the population level in highly endemic settings.

Methods: A prospective 15-month cohort study of 127 infants and 119 elderly people was combined with animal and food surveillance to determine the incidence and severity of Salmonella and Campylobacter gastroenteritis in a comparatively prosperous rural community in Mexico.

Results: Salmonella and Campylobacter were isolated in up to 75% and 57%, respectively, of raw retail meat and in up to 4.
