“…The high percentage of C. jejuni strains with this mutation is consistent with recent studies from Chile, reporting ciprofloxacin resistance in 30-60% of C. jejuni strains[18,[20][21][22]. WhilePorte et al reported that most resistant strains were associated with ST-48 and ST-353, in our study, there was no particular association of this mutation while most ST-475 isolates (the second most prevalent ST) not have this mutation.Although fluoroquinolones are not first choice antimicrobial for human campylobacteriosis, these high levels of resistance might be a consequence of their broad use in animal husbandry.…”

“…In addition to CC-21, we identified high prevalence rates of CC-48 (13%) and CC-52 (7.3%). ST-475 from CC-48 was the second most prevalent ST (11.6%) identified (Figure 1A).There are only two previous reports of MLST data of clinical C. jejuni strains from Chile[18,22]. Both reports identified four major CCs and STs, including CC-21 (ST-50), CC-48 (ST-475), CC-257 (ST-257), and CC-353 (ST-353).…”

“…En Valdivia se ha evidenciado el cambio más notorio en el patrón de resistencia a nivel nacional. De hecho, se pasó de una completa sensibilidad a ciprofloxacina en cepas clínicas de C. jejuni aisladas entre los años 1997-1998 28 , a casi la mitad de las cepas resistentes a este antimicrobiano, dos décadas más tarde 29 . El aumento de la resistencia a tetraciclina también es considerable; en el año 2000 la resistencia alcanzaba a 1,8% de las cepas y los datos más actuales la sitúan sobre 20% (Tabla 2).…”

“…Además, el hecho de que gran parte de los aislados resistentes a ciprofloxacina provengan de niños, en quienes no se recomienda usar este tipo de antimicrobiano como tratamiento empírico de diarrea, hace suponer que la infección ha sido provocada por bacterias previamente resistentes 9,32 . Por otra parte, en los últimos años también se ha comenzado a notar una incipiente resistencia a eritromicina 15, 23,29 . Hasta el momento, no se ha detectado resistencia a gentamicina en cepas clínicas aisladas en Chile (Tabla 2) y, por lo tanto, este antimicrobiano se convierte en un buen recurso terapéutico para infecciones sistémicas.…”
