Perfil de resistencia antimicrobiana de bacterias aisladas de infecciones y de la microbiota ocular

Abstract: Introducción: en los últimos años, el aumento de cepas resistentes a los antimicrobianos puede deberse a su uso indiscriminado y excesivo. La Organización Mundial de la Salud (OMS) ha promovido la vigilancia mundial de la resistencia a los antimicrobianos; sin embargo, la mayor limitante es la falta de datos confiables en algunos países. Estudios como el Antibiotic Resistance Monitoring in Ocular Microorganisms (ARMOR), de 2009 y 2013, y el Tracking Resistance in the United States Today (TRUST) refieren que el… Show more

“…Nevertheless, these same microorganisms can cause infection of the ocular tissue due to imbalances in the immune and defence mechanisms of the eye itself, for example, physical barriers (eyelids and eyelashes), tear film with lactoferrin, lysozyme, and IgA (antimicrobial and anti-inflammatory) [2,42]. Such is the impact of this imbalance in the microbiota-host relationship that up to 73% of the total bacterial pathogens identified have been reported as part of the microbiota [43]. In contrast to our work, some studies indicate that the most prevalent microorganism in these infections is S. aureus, where a high percentage are methicillin-resistant S. aureus (MRSA) [44,45].…”

“…Igualmente, más del 50 % de los ecn fueron meticilino resistentes y más del 60 % de estas bacterias también tenían resistencia a azitromicina y ciprofloxacina (12,13). En una revisión de la literatura de la ram en aislados oculares, se encontró que en América (Estados Unidos, México, Colombia, Cuba, Venezuela, Brasil y Paraguay), el S. aureus y los ecn son resistentes principalmente a macrólidos y betalactámicos (14).…”
