Clostridium difficile, the causal agent of antibiotic-associated diarrhea, has a complex epidemiology poorly studied in Latin America. We performed a robust genomic and phenotypic profiling of 53 C. difficile clinical isolates established from diarrheal samples from either intrahospital (IH) or community (CO) populations in central Colombia.

Some well-known Clostridiales species such as and are agents of high impact diseases worldwide. Nevertheless, other foreseen Clostridiales species have recently emerged such as and . Three fecal isolates were identified as (Gcol.

Background: The aim of this study was to evaluate the frequency of toxigenic and infections at health care facility-onset (HCFO) and community-onset (CO), in two health care centers (HCC) in Bogotá, Colombia. A total of 220 stool samples from patients presenting diarrhea acquired at HCFO or CO were analyzed by several PCR tests.

Results: We found that 65.

Multilocus sequence typing (MLST) has become a useful tool for studying the genetic diversity of important public health pathogens, such as (). Four MLST schemes have been proposed for (data available from Chlamydiales MLST databases). However, the lack of a sole standardized scheme represents the greatest limitation regarding typing this species.

(CD) produces antibiotic associated diarrhea and leads to a broad range of diseases. The source of CD infection (CDI) acquisition and toxigenic profile are factors determining the impact of CD. This study aimed at detecting healthcare facility onset- (HCFO) and community-onset (CO) CDI and describing their toxigenic profiles in Bogotá, Colombia.

Article Synopsis
  • CDI (Clostridioides difficile infection) is a significant concern both in hospitals and in the community, leading to antibiotic-associated diarrhea and other gastrointestinal issues.
  • A case study of a 30-year-old woman, who developed community acquired-CDI after antibiotic treatment for a cat bite, reveals the presence of hypervirulent bacterial strains tied to her condition.
  • Analysis of bacterial isolates showed common toxin profiles and differentiated antibiotic resistance markers, highlighting the urgent need for monitoring CDI infections, especially those acquired outside of healthcare settings.

Background: Multilocus sequence typing (MLST) is a highly discriminatory typing strategy; it is reproducible and scalable. There is a MLST scheme for Clostridium difficile (CD), a gram positive bacillus causing different pathologies of the gastrointestinal tract. This work was aimed at describing the frequency of sequence types (STs) and Clades (C) reported and evalute the intra-taxa diversity in the CD MLST database (CD-MLST-db) using an MLSA approach.

Background: Chlamydia trachomatis (C. trachomatis), an obligate intracellular bacterium, is the commonest infectious bacterial agent of sexual transmission throughout the world. It has been shown that the presence of this bacteria in the cervix represents a risk regarding HPV persistence and, thereafter, in developing cervical cancer (CC).
