Abstract
TORIBIO JIMENEZ, Jeiry et al. Asymptomatic carriers of resistant methicillin Staphylococcus aureus (MRSA) in fishermen and horticulturists in Guerrero, Mexico. JONNPR [online]. 2020, vol.5, n.12, pp.1482-1489. Epub Dec 18, 2023. ISSN 2529-850X. https://dx.doi.org/10.19230/jonnpr.3755.
Methicillin-resistant Staphylococcus aureus (MRSA) has been classically considered an opportunistic pathogen, causing various infections in humans and animals, it is resistant to multiple specific antibiotics that hinder its control and treatment, it is found in the nasal passages of healthy people and it has been called a carrier state that produces reasons for alarm, since its appearance in the 1970s, which has spread in such a way that today it is the most important pathogen in the world considered a public health problem.
Aim.
Metodology.
Asymptomatic carriers were detected in fishermen and horticulturists in the state of Guerrero. 107 nasal samples were taken, S. aureus strains were cultivated and identified with specific biochemical tests, MRSA strains were evaluated by the disk diffusion method, by the Kirby-Bauer technique, following the international standards of CLSI.
Results.
Results. Were detected by resistance to oxacillin and being cefoxitin positive, of the results detected from 57 fishermen and 50 horticulturists, only four MRSA They were detected due to resistance to oxacillin and being cefoxitin positive. From the results obtained from 57 fishermen and 50 horticulturists, only four MRSA strains were detected in fishermen; detection of these strains in the environment could be important.
Conclusion.
The presence of S. aureus is of epidemiological significance since it can be transmitted from people to people, food handlers that carry, since S. aureus, producers of enterotoxins, cause food poisoning, which is why this is the first report on carrier status of MRSA in fishermen and horticulturists in the state of Guerrero. Therefore, it is necessary to pay attention, since otherwise the results in public health could be negative.
