Prevalence of HPV genotypes determined by PCR and DNA sequencing in cervical specimens from French women with or without abnormalities.

Background: Epidemiological data on human papillomavirus (HPV) are needed to estimate potential changes in type distribution induced by recent HPV vaccination strategies.

Objectives And Study Design: The epidemiological distribution of HPV in 669 cervical specimens from French women with and without cytological abnormalities was evaluated using type-specific PCR or sequencing. The results were compared with those obtained using the Digene high-risk Hybrid Capture 2 (HR-HC2) assay.

[Enteric parasites and AIDS in Haiti: utility of detection and treatment of intestinal parasites in family members].

Intestinal parasites and human immunodeficiency virus (HIV) are major health problems in Haiti. Both entities are known to interact strongly with cell-mediated immunity. The purpose of this study undertaken in Port-au-Prince, Haiti was to evaluate the risk of enteric parasite transmission between HIV-infected patients and family members.

Assessment of Leishmania promastigote growth in vitro by means of nucleoside hydrolase activity determination.

Nucleoside hydrolases (NH) are involved in the purine salvage pathway of protozoan cells for the biosynthesis of nucleic acids. We developed a simple and reliable microassay based on N-ribohydrolase dosage using 4-nitrophenyl-beta-D-ribofuranoside (NPR) substrate for the quantification of Leishmania infantum. The free promastigote stage of L.
