La bacteria _E. coli_ resistente a los antibióticos es mucho más
prevalente en las aldeas situadas junto a las carreteras, que en las
aldeas rurales ubicadas lejos de las rutas, lo cual indica que las
carreteras desempeñan un papel importante en la propagación o la
contención de las bacterias resistentes a los antibióticos, conocidas
como superbacterias.
Muchos estudios sobre varias enfermedades infecciosas han demostrado
que los caminos tienen un impacto en la propagación de las
enfermedades, pero éste es el primer estudio conocido que muestra que
las carreteras también tienen un impacto en la propagación de las
bacterias resistentes a los antibióticos, dijo Joe Eisenberg, coautor
y profesor en la Escuela de Salud Pública de la Universidad de
Michigan (UM).
Los investigadores en la escuela de la UM y sus colegas de la
Universidad de San Francisco en Quito (Ecuador), y el Trinity College
estudiaron durante cinco años una región en el noroeste de Ecuador,
enfocándose en la _E. coli_ resistente a los antibióticos y la
combinación común de antibióticos de ampicilina y sulfametoxazol.

Colombia- Toxoplasmosis trends across Columbian cities
22 July 2011
Elespectador.com [CAHFS-DailyNews]
The Colombian National Study on Congenital Toxoplasmosis was conducted in 7 Colombian cities and 19 hospitals tracking 15,333 newborns. It revealed that there were significant differences in infection rates among the studied cities. Although other factors were studied, rainfall was significantly correlated with increased incidence of toxoplasmosis. This is because when it rains there is usually an increase in the number of cases of toxoplasmosis because water carries infectious material into rivers and eventually to the aqueducts. The parasite can remain in the soil for up to one year without losing its infectivity.

Haiti- Cholera, diarrhea, dysentery update
4 May 2011
United Nations [edited] [ProMed]
After the devastating earthquake of Jan. 2010, cholera appeared in Haiti for the first time in nearly a century. The outbreak subsequently claimed over 4,500 lives, sickened almost 300,000 people, and continues to cause infections and deaths in Haiti today. The source of the cholera has been controversial. In order to determine the source of the outbreak definitively, the Secretary-General of the UN formed an Independent Panel of four international experts with a mandate to investigate and seek to determine the source of the 2010 cholera outbreak in Haiti. To fulfill this mandate, concurrent epidemiological, water and sanitation, and molecular analysis investigations were carried out. The hydrological data, combined with the epidemiological timeline, and supported by the molecular analysis information verifies that contaminated river water was the likely route of spread of Vibrio cholerae from the mountains of Mirebalais to the coastal areas around the Artibonite River Delta.
Colombia- Antimicrobial susceptibility of Listeria monocytogenes food isolates from different cities
14 April 2011
Foodborne Pathogens and Disease [edited] [BITES]
One hundred eight Listeria monocytogenes food isolates from four cities in Colombia were characterized for antimicrobial susceptibility. Isolates were evaluated against 17 antimicrobials. Susceptibility found for ampicillin, amoxicillin/clavulanic acid, and chloramphenicol was 100%, whereas it was 98% for other antimicrobials such as trimethoprim/sulfamethoxazole, 97% for azithromycin, 92% for vancomycin, 90% for erythromycin, 86% for tetracycline, 84% for penicillin, 70% for ciprofloxacin, 57% for rifampin, 56% for meropenem, and 32% for clindamycin. Natural resistance to cephalosporins was confirmed in all cases, and 16% of isolates were nonsusceptible to penicillin. Colombian food isolates displayed high resistance to clindamycin, meropenem, rifampin, and ciprofloxacin (30%–65%), and the primary drugs of choice against listeriosis remain effective for most of isolates (84%).
Argentina- Factors associated with sporadic verotoxigenic Escherichia coli infection in children with diarrhea
14 April 2011
Foodborne Pathogens and Disease [edited] [BITES]
Verotoxigenic Escherichia coli (VTEC) are one of the most important emerging foodborne pathogens and the principal cause of hemolytic uremic syndrome (HUS). Argentina is the country with the highest incidence of HUS in children less than 5 years of age. The lack of specific treatment, combined with the high morbidity rate of VTEC infection, makes prevention the main tool for reducing the incidence of HUS. The current work aimed at assessing the factors associated with sporadic VTEC infection in children with acute diarrhea from the Central Eastern area of Argentina where the incidence rate of HUS in children under 5 is the highest worldwide. Researchers believe that the data obtained from this study further the current knowledge about the epidemiology of VTEC infection in Argentina and could be considered when planning strategies for the prevention of the disease.
Chile- Burden of acute gastrointestinal illness, 2008
09 March 2011
Epidemiology and Infection [edited] [BITES]
The purpose of this study was to determine the magnitude and distribution of acute gastrointestinal illness (GI) in the Chilean population, describe its burden and presentation, identify risk factors associated with GI and assess the differences between a 7-day, 15-day and a 30-day recall period in the population-based burden of illness study design. Face-to-face surveys were conducted on more about six thousand randomly selected residents in the Metropolitan region, Chile in 2008.
