The alarming increase in bacterial resistance to antibiotics worldwide has exposed sources of this phenomenon other than the hospital and the community, where water has become increasingly important. Aquatic environments are the source and natural habitat of a large number of microorganisms, including antibiotic-resistant bacteria. They are also co...

Introduction: Bacterial resistance is a multifactorial phenomenon, where scenarios other than the hospital setting have gained significant importance. Objective: To determine the presence of beta-lactam-resistant Gram-negative bacilli of clinical importance in wastewater from a highly complex hospital in Me-dellín, Antioquia.Materials and methods:...

Hospital wastewater (HWW) discharges are among the main sources of antibiotic-resistant bacteria. This study detected a high frequency of beta-lactamase-producing Gram-negative Bacilli in HWW of different geographical regions of Colombia, even in the presence of the wastewater treatment plant, highlighting the importance of regulating these environ...

Several physicochemical and season factors have been related to the abundance of antibiotic resistance genes (ARGs) in wastewater treatment plants (WWTPs), considered hotspots of bacterial resistance. However, few studies on the subject have been carried out in tropical countries endemic for resistance mechanisms such as bla KPC. In this study, the...

In developing countries, where high levels of antimicrobial resistance are observed in hospitals, the surveillance of this phenomenon in wastewater treatment plants (WWTPs) and the environment is very limited, especially using cutting-edge culture-independent methods. In this study, the composition of bacterial communities, the resistome and mobilo...

Wastewater treatment plants (WWTPs) are considered to be a reservoir and a source of bacterial resistance. Worryingly, the presence of carbapenem-resistant Gram-negative bacilli (CRGNB) in WWTPs has recently been reported, but there are still many research gaps regarding its emergence and impact. The distribution of CRGNB in the different stages of...

Introducción. En países en vía de desarrollo donde se observan altos niveles de resistencia bacteriana en hospitales‚ la vigilancia de la resistencia en el ambiente y plantas de tratamiento de agua residual (PTARs) es poca y menos empleando enfoques metagenómicos. En este estudio se determinó la composición las comunidades bacterianas y la ocurrenc...

Objectives Carbapenem-resistant Gram-negative bacilli (CRGNB) have been reported in different wastewater treatment plants (WWTPs) throughout the world; however, few studies have described the antimicrobial resistance profile in different CRGNB throughout WWTPs, information that would identify points of selection of resistant bacteria. The objective...

Increasing beta-lactam resistance has led to the exploration of different places, such as wastewater treatment plants (WWTPs) which have been considered to be reservoirs and sources of bacterial resistance. This work aims to determine the presence of beta-lactamase-producing-Enterobacteriaceae in different points of a WWTP in Colombia. Six sampling...

El aumento de la resistencia a betalactámicos ha llevado a explorar espacios diferentes al hospitalario como las plantas de tratamiento de aguas residuales (PTAR), consideradas recientemente como reservorios y fuentes de diseminación de la resistencia bacteriana. En este trabajo se propuso describir la presencia de enterobacterias resistentes a bet...

The wastewater treatment plants (WWTP) are considered one reservoir of antimicrobial resistance. Beta-lactam antibiotics are one of the most used and useful in the treatment of infections in humans. In Colombia, the description beta-lactam resistance in Gram-negative bacilli (GNB) is frequently performed in the hospital setting, however, the preval...

Background: The wastewater treatment plants (WWTPs) are considered as one of the most important reservoir of bacterial resistance. Carbapenem-resistant Gram-negative Bacilli have been described in different WWTP around the world. However, few studies describe the distribution of these microorganisms in different points of WWTP. The objective is to...

Colombia is considered an endemic region for Carbapenem resistance. This problem has been evidenced in the Colombian's hospitals, but the knowledge about of Carbapenem resistance in the environment and the community is limited. Several studies have pointed the wastewater treatment plants (WWTP) as one of the main sources and receptors of resistant...

In Colombia, the problem of resistant to carbapenems Gram-negative bacteria has been evidenced in hospitals but knowledge in wastewater treatment plant (WWTP) is limited. The aim of this study was to determine the presence of Carbapenem-resistant gram-negative bacteria in one WWTP of Medellín, Colombia.

Introduction: Colonization plays a major role in the epidemiology and pathogenesis of Staphylococcus aureus infections. The child population is one of the most susceptible to colonization; however, community and children studies are limited in Colombia. Objective: To assess the clonal relationship of S.aureus strains isolated from colonized chil...

Introduction: Acinetobacter baumannii is an opportunistic bacterium which infects seriously ill patients, particularly those with ventilator-associated pneumonia and bacteremia. The emergence of resistance to carbapenem limits the options for the treatment of infections caused by this bacterium. Objective: To describe the clinical and molecular ch...

Staphylococcus aureus has a particular ability to colonize the skin and mucosae of human beings and different animal species. Several studies have demonstrated the important role of such colonization in the pathogenesis and epidemiology of staphylococcal infections. Nasal carriers have been shown to be an important source for S. aureus spread. Most...

Background: Clinical significance of Staphylococcus aureus colonization has been demonstrated in hospital settings; however, studies in the community have shown contrasting results regarding the relevance of colonization in infection by community-associated MRSA (CA-MRSA). In Colombia there are few studies on S. aureus colonization. The aim of thi...

Recent reports highlight the incursion of community-associated MRSA within healthcare settings. However, knowledge of this phenomenon remains limited in Latin America. The aim of this study was to evaluate the molecular epidemiology of MRSA in three tertiary-care hospitals in Medellín, Colombia. An observational cross-sectional study was conducted...

Virulence and antibiotic resistance are significant determinants of the types of infections caused by Staphylococcus aureus and paediatric groups remain among the most commonly affected populations. The goal of this study was to characterise virulence genes of methicillin-susceptible S. aureus (MSSA) and methicillin-resistant S. aureus (MRSA) strai...
