New Variants of Pseudomonas High-Risk Clone ST233 Associated with an Outbreak in a Mexican Paediatric Hospital.

Recent multidrug resistance in has favoured the adaptation and dissemination of worldwide high-risk strains. In June 2018, 15 strains isolated from patients and a contaminated multi-dose meropenem vial were characterized to assess their association to an outbreak in a Mexican paediatric hospital. The strains were characterized by antibiotic susceptibility profiling, virulence factors' production, and biofilm formation.

Infectious Agents in Childhood Leukemia.

Acute leukemia is the most common pediatric cancer, representing one-third of all cancers that occurs in under 15 year olds, with a varied incidence worldwide. Although a number of advances have increased the knowledge of leukemia pathophysiology, its etiology remains less well understood. The role of infectious agents, such as viruses, bacteria, or parasites, in the pathogenesis of leukemia has been discussed.

[Maternal-fetal transmission of Trypanosoma cruzi, a health problem slightly studied in Mexico: case Chiapas].

Objective: To determine the Trypanosoma cruzi infection prevalence in 1125 pregnant women and the transmission frequency to their children from Tapachula and Palenque, Chiapas.

Materials And Methods: We determined the prevalence by serology tests and the transmission frequency by polymerase chain reaction (PCR) and T. cruzi reactivity capacity after 12 months.

Maternal fetal transmission of Trypanosoma cruzi: a problem of public health little studied in Mexico.

The first case of neonatal Chagas was reported in Mexico in 1998, but there have been no studies since then. Therefore, we investigated the rates of congenital infection of Trypanosoma cruzi by examining the seroprevalence among 1448 pregnant women in Oaxaca, Jalisco and Mexico City. We performed ELISAs to screen for recombinant and total antigens in mothers, and examined the frequency of congenital T.
