Multi-resistant and Cordoban bacteria

They detect multidrug-resistant bacteria in the Suquía River and in the environment of Córdoba. There are more and more environmental problems.

All environment

Multidrug-resistant bacteria are the main responsible for intra-hospital infections. For researchers, sewage spills and their outflow into the watercourse that crosses the provincial capital facilitate their dispersion into the urban and peri-urban environment. While these are not bacteria that cause mass contagion or large epidemics, they recommend monitoring the situation. By 2050, deaths from these almost invincible germs are expected to be the leading cause of death worldwide.

A multidisciplinary study identified a set of multidrug-resistant bacteria in the Cordoba environment and in the Suquía River. Sometimes these microorganisms — which cause infections of various gravity— they are carriers of a gene that makes them resistant to the most commonly used antibiotics. The ones treatments on these multiresistant bacteria are usually more complex and, in extreme cases, ineffective.

“ With sewage, this type of multidrug-resistant bacteria is being poured into the environment. While we should not be afraid of the emergence of an epidemic, these sewage spills can cause problems in the public health,” explains Héctor Alex Saka, researcher at the Department of Clinical Biochemistry of the Faculty of Chemical Sciences of the UNC.

Causes and consequences

Self-medication, misuse and abuse of antibiotics. Sewage overages that carry large amounts of bacteria together with low but active amounts of antibiotics in excreta. The use of antibiotics as growth promoters of animals in agricultural production. These are some of the factors that accelerate the development of multidrug-resistant bacteria.

“ In condition , it can take decades for a bacteria to develop resistance. But, at the being regularly subjected to the action of antibiotics, you can achieve it in less time. Today, we note that in five or six years, or even less, some bacteria become resistant to antibiotics, the development of which could lead to ten or more years of research and large investments,” says Saka.

The World Organization Health warns that currently 700 thousand people die per year due to the action of bacteria multi-resistant. By 2050, that figure could reach 10 million and be the leading cause of death.

Local Diagnostics

These almost invincible microbes have become a global concern. Saka and a team of researchers from UNC and the Catholic University of Cordoba with the LACE laboratory began to study. Its object was the situation of multidrug-resistant bacteria in the urban and peri-urban environment of the city of Córdoba. Among them, the Suquía River.


They found Enterobacteria, enterococci and staphylococcus aureus resistant. These bacteria cause multiple infections in the hospital and in the community can cause injury infections, urinary tract, pneumonia, among others. “When the infection is provoked by multidrug-resistant bacteria, it is a problem because there are few therapeutic options
