A One Health approach based on genomics for enhancing the surveillance in Colombia.

Objectives: This study aimed to provide evidence of the domestic benefits of introducing an integrative genomic analysis from the One Health approach in the national surveillance of between 1997-2017 in Colombia.

Methods: Data on from clinical laboratory-based surveillance between 1997-2017 and from a national cross-sectional study at chicken retail stores in Colombia were compared using a phenotypic, molecular, and genomic approaches. Additional analysis by serovar using single nucleotide polymorphism was developed to increase the resolution of the relatedness between the interfaces.

Bacteremia by non-O1/non-O139 Vibrio cholerae: Case description and literature review.

Bacteremia by non-O1/non-O139 Vibrio cholerae is a rare entity associated with high mortality rates. We report a case of non-O1/non-O139 V. cholerae bacteremia confirmed by polymerase chain reaction and agglutination tests.

Characterization of extended spectrum β-lactamases in Colombian clinical isolates of non-typhoidal Salmonella enterica between 1997 and 2022.

Introduction. Salmonella spp. is a zoonotic pathogen transmitted to humans through contaminated water or food.

Class 1 integrons in clinical and swine industry isolates of Typhimurium from Colombia, dating 1997 to 2017.

subsp. serovar Typhimurium (. Typhimurium) has been linked to outbreaks of foodborne gastroenteritis disease, and the emergence of antimicrobial-resistant clones.

A genomic snapshot of Salmonella enterica serovar Typhi in Colombia.

Little is known about the genetic diversity of Salmonella enterica serovar Typhi (S. Typhi) circulating in Latin America. It has been observed that typhoid fever is still endemic in this part of the world; however, a lack of standardized blood culture surveillance across Latin American makes estimating the true disease burden problematic.

Laboratory-based surveillance of Shigella spp. from human clinical cases in Colombia, 1997-2018.

Introduction: Shigellosis is endemic in low-and middle-income countries, causing approximately 125 million episodes of diarrhea and leading to approximately 160 .000 deaths annually one-third of which is associated with children.

Objective: To describe the characteristics and antimicrobial resistance profiles of Shigella species recovered in Colombia from 1997 to 2018.

An outbreak of Salmonella enterica subsp. enterica serovar Give associated with foodborne illness in the department of Vichada, Colombia, 2015.

Introduction: Salmonella enterica subsp. enterica serovar Give is found in ruminants, pigs, poultry, and aquatic environments, but rarely in humans. In Colombia, this serotype was ranked 11th.

Molecular and phenotypic characterization of Salmonella Typhimurium monophasic variant (1,4,[5],12:i:-) from Colombian clinical isolates.

Introduction. The Salmonella Typhimurium monophasic variant (1,4,[5],12:i:-) is currently the most commonly detected variant in Salmonella surveillance programs worldwide. In Colombia, the Salmonella enterica monophasic variant is the fourth most common clinical isolate recovered through the laboratory surveillance of the Grupo de Microbiología from the Instituto Nacional de Salud; however, it is unknown whether these isolates are closely related to the monophasic Typhimurium variant, which circulates globally, and their genetic and phenotypic characteristics have not been reported.

Surveillance of Salmonella enterica serovar Typhi in Colombia, 2012-2015.

Salmonella Typhi (S. Typhi) is the causative agent of typhoid fever; a systemic disease affecting ~20 million people per year globally. There are little data regarding the contemporary epidemiology of typhoid in Latin America.

Genomic and Molecular Characterization of Clinical Isolates of Enterobacteriaceae Harboring in Colombia, 2002 to 2016.

Polymyxins are last-resort antimicrobial agents used to treat infections caused by carbapenem-resistant Due to the worldwide dissemination of polymyxin resistance in animal and human isolates, we aimed to characterize polymyxin resistance associated with the presence of in and nonfermenter Gram-negative bacilli, using isolates collected retrospectively in Colombia from 2002 to 2016. A total of 5,887 Gram-negative clinical isolates were studied, and 513 were found to be resistant to the polymyxins. Susceptibility to colistin was confirmed by broth microdilution for all -positive isolates, and these were further subjected to whole-genome sequencing (WGS).

Laboratory surveillance of Salmonella enterica from human clinical cases in Colombia 2005-2011.

Introduction: Salmonella is an enteropathogen acquired through contaminated food or water. In Colombia, Salmonella spp. is included in the national surveillance of Acute Diarrhoeal Diseases and typhoid fever initiated in 1997.

[Molecular characterization of Shigella sonnei isolates recovered by the Laboratory Surveillance Program for Acute Diarrheal Disease in Colombia].

Introduction: In Colombia, Shigella sonnei is one of the most frequently isolated serotypes (53.4%) in human clinical samples associated with diarrheal acute disease. The identification of DNA restriction patterns by pulsed field gel electrophoresis is the basis for the molecular surveillance of S.

[A nalidixic acid-resistant Salmonella enteritidis outbreak in Popayán, Cauca, 2011].

Introduction: Salmonella Enteritidis is recognized worldwide as one of the main agents of human gastrointestinal infection. Several reports indicate the presence of isolates with decreased sensitivity to ciprofloxacin that can lead to a delayed response or the development of resistance during treatment.

Objective: To describe and characterize isolates of Salmonella Enteritidis associated to an outbreak of food-borne diseases in Popayán, Cauca.
