Stool samples from children seeking medical attention in 2 outpatient clinics, a large emergency department, and 2 hospital wards were evaluated for HuCVs by reverse transcription—polymerase chain reaction, using primers based on a conserved sequence of the polymerase region of a previously sequenced Chilean strain. Epidemiologic and clinical characteristics of rotavirus disease during five years of surveillance in Venezuela. To our knowledge, this is the first prospective, active surveillance for gastroenteritis dalicivirus in Latin America that included a thorough caliciviruus for HuCVs.

Enteropathogenic Escherichia colienterotoxigenic E. Despite seroprevalence studies that indicate high exposure to HuCVs among children, detection of this pathogen in stools of children with diarrhea has been mostly unsuccessful [ 56 ]. Clin Microbiol Rev ; Rev Infect Dis ; 13 5: Control samples were not available from the outpatient clinics. Acceso 24 de agosto de Please review our privacy policy.

The purpose of this work was to study rotavirus infection in neonates at the Maternity Hospital and compare the caliciivrus data with those previously obtained.


Sequential evolution of genotype GII.

Etiology of sporadic cases of pediatric acute gastroenteritis in Asturias, Spain, and calicuvirus and characterization of norovirus strains involved. Most HuCV outbreaks occurred in the home, with outbreaks in childcare centers and schools occurring next most frequently; only a small fraction occurred in restaurants.

Use of appropriate primers in well-designed epidemiologic studies will define more precisely the role of HuCVs in acute diarrhea of children in developing countries.

Caliciviruses and Foodborne Gastroenteritis, Chile

Although the number of HuCV detections was not high enough to clearly define overall epidemiology, we detected HuCVs year-round without clearly identifiable seasonal peaks. Five health care facilities, including 2 outpatient clinics, a large ED, and 2 hospital wards of the Chilean National Health Care System, enrolled patients.

Treinta y siete de las 58 muestras sospechosas fueron analizadas por RT-PCR utilizando dos juegos de cebadores con especificidades distintas, sin embargo, ninguna de ellas pudo ser confirmada como positiva. Rotaviruses and their replication.

The diagnosis of norovirus infections is not performed routinely in many laboratories, but those involved in epidemiological surveillance have identified norovirus strains that evolve sequentially over time, similarly to Influenza viruses.

Both participating outpatient clinics and 1 hospital ward Roberto del Rio Hospital; hospital 2 belong to the north calicivirys care area of Santiago. Human calicivirus HuCV positivity by year and by source of stool samples. Dennis Kasper, et al.
