Low prevalence of high risk human papillomavirus in normal oral mucosa by hybrid capture 2.

High risk human papillomavirus (HR-HPV) are recognized as a necessary factor to development cervical cancer. During the last decade many studies have found HR-HPV in oral squamous cell carcinoma (OSCC) and normal oral mucosa, however the association between HR-HPV and OSCC is still uncertain. The aim of the study was to determine DNA HR-HPV in normal oral cavity of healthy adults.

Detection of unusual strains of RV in patients with acute diarrhoea in Mexico.

Background: Group A rotaviruses are a major cause of acute gastroenteritis in infants. Human strains with a short RNA pattern generally exhibit subgroup I, G2, P1B[4] specificity, those with a long RNA pattern show subgroup II, G1, G3 or G4, P1A[8] specificity. The presence of strains with unusual specificities has been reported worldwide over the last decade.

Clinical manifestations of the rotavirus infection and his relation with the electropherotypes and serotypes detected during 1998 and 1999 in Merida, Yucatan, Mexico.

Background: Group A rotavirus (RV) is associated with acute infectious diarrhea (AID) in children and adults. The clinical manifestations of RV infection are classified as slight, moderate and severe and could be the results of differing rotaviral serotypes. Attempts have been made to correlate the severity of the infection with specific RV groups, subgroups (SG) serotypes and electropherotypes, but the results have been inconclusive.

[Rotavirus infections in Yucatan, Mexico, in 2000].

Objective: To describe the cases of rotavirus infection occurred in Yucatan, Mexico, in the year 2000.

Material And Methods: From January to May 2000, were studied 668 patients with acute infectious diarrhea and their fecal samples. A questionnaire was applied and the samples were analyzed by polyacrylamide gel electrophoresis with silver stained.
