Abstract
Escherichia coli productor de toxina Shiga (STEC) es un patógeno emergente a nivel mundial siendo reconocido como agente causal de enfermedades severas en el hombre, como colitis hemorrágica (CH) y síndrome urémico hemolítico (SUH). El objetivo consistió en determinar el rol de los animales de compañía como potenciales reservorios de STEC en la cadena epidemiológica del SUH. Se realizó un estudio descriptivo de corte transversal. Entre octubre de 2010 y abril de 2013 se procesaron 162 muestras de perros y gatos realizándose PCR múltiple para la detección de los genes stx1, stx2 y rfbO157, no detectándose señal positiva por PCR en ninguna de las muestras procesadas. Estos resultados de ausencia de STEC en los animales estudiados podría deberse a que la alimentación de los mismos resultó principalmente con alimentos balanceados ya que el consumo de alimentos contaminados, como por ejemplo carne molida, productos cárnicos crudos o insuficientemente cocidos, constituyen una de las principales fuentes de infección para este microorganismo.
Escherichia coli Shiga toxin-producer (STEC) is an emerging pathogen worldwide being recognized as a cause of severe human diseases, such as hemorrhagic colitis (HC) and hemolytic uremic syndrome (HUS). The aim of this work was to determine the role of companion animals as potential reservoirs of STEC in the epidemiological chain of HUS. A descriptive cross-sectional study was conducted. Between October 2010 and April 2013, samples from 162 dogs and cats were processed performing multiplex PCR for detection of stx1, stx2 and rfbO157 genes. Was not detected positive signal by PCR in any of the processed samples. These results from the absence of STEC in animals studied could be because feeding them with feed resulted primarily because the consumption of contaminated foods, such as ground beef, meat products raw or undercooked, constitutes a major infection source for this microorganism.
