“…Although a double point mutation was found for a few isolates in both studies, 38% to 41.6% of S. epidermidis isolates from conjunctival sacs preoperatively harbored at least one point mutation in the gyrA gene. Moreover, it has been demonstrated that prophylactic use of topical levofloxacin and moxifloxacin is associated with selection of fluoroquinolone-resistant S. epidermidis and others CoNS from the normal conjunctival and nasopharynx microbiota (4,18,25). The MSSE isolates resistant to 8-methoxyfluoroquinolones included in our study were recovered mostly from endophthalmitis cases following intraocular surgery and intravitreal injection.…”

“…Fluoroquinolone-resistant CoNS isolates from the normal conjunctiva microbiota have been recovered from patients undergoing intraocular surgery and intravitreal injection (4,5,(22)(23)(24). In addition, two studies found mutations within the QRDR in around 50% to 58% of S. epidermidis isolates from in the conjunctival sacs before preoperative instillation of antibiotic from patients undergoing intraocular surgeries (18,19).…”

“…Acorde con la literatura científica, las bacterias más frecuentes en la microbiota conjuntival, identificadas mediante el sistema automatizado VI-TEK, fueron del género Staphylococcus, con un porcentaje similar (55,6 %) al reportado en varios estudios (9,12,14,24). Los estafilococos coagulasa negativos fueron las bacterias más representativas (95 %), dentro de los cuales S. epidermidis fue la especie más aislada (50 %), junto con otras -S. warneri, S. haemolyticus, S. auricularis, S. hominis y S. capitas-previamente reportadas en la microbiota conjuntiva (7,24).…”

La alta frecuencia de identificación de este género en las dos muestras de conjuntiva de cada sujeto corrobora que es el principal constituyente de la microbiota residente en el ojo.…”
