Article Synopsis
- The study presents draft genome sequences of four Bordetella pertussis isolates linked to significant outbreaks in northeastern Mexico from 2008 to 2014.
- These isolates belong to a specific lineage and are categorized into two main clusters based on their genetic alleles.
- The research contributes to understanding the genetic diversity of B. pertussis during recent outbreaks.*
Immunization with the tetanus, diphtheria, and pertussis (Tdap) vaccine raises controversies on immunogenicity and possible antibody interference. We performed an experimental, double-blind, parallel group controlled clinical trial to evaluate the safety and immunogenicity of the Tdap vaccine in 204 pregnant women and their children and to determine its interference in antibody production. Pregnant women 18 to 38 y of age with 12 to 24 weeks gestation, a low obstetric risk, and without serious disease were randomly selected.

Objective: The aim of this study was to evaluate the sensitivity and specificity of polymerase chain reaction for detection of Brucella spp in human blood samples compared with the serological tests and blood culture.
Material And Methods: In 2005, a total of 92 people were sampled from the towns of Anahuac and Sabinas Hidalgo, Nuevo Leon, where an outbreak of human cases had taken place in the same year as this study. The sera collected were analyzed by serological tests according to the NOM 022-SS2-1994.
