Pulex irritans is the only cosmopolitan flea species and the most studied one within the genus Pulex. It has importance in public health since it commonly parasitizes humans causing dermatitis, and it has been also implicated in the transmission of bacterial pathogens.

description Pulex irritans is the only cosmopolitan flea species and the most studied one within the genus Pulex. It has importance in public health since it commonly parasitizes humans causing dermatitis, and it has been also implicated in the transmission of bacterial pathogens. Pulex irritans has been confused with the closely related Pulex simulans species for years. Herein, Pulex specimens collected from a Pampas fox and a Chacoan peccary from northwestern Argentina were identified by comparison with type specimens. In addition, the presence of Bartonella spp. and Rickettsia spp. was investigated using PCR assays. Our results provided characters of diagnostic importance to identify P. irritans, which include the shape of sternite VII in the females, and of the aedeagal sclerite, clasper and crochet in the males. Besides, we report for the first time P. irritans parasitizing a peccary. This finding reinforces the hypothesis of the origin of this flea associated with this mammal, and then colonizing humans and domestic mammals. There was no evidence of Bartonella or Rickettsia DNA in the analyzed fleas. This information even if negative may be considered relevant for P. irritans from Argentina.

Tiene importancia en la salud pública ya que comúnmente parasita a los seres humanos causando dermatitis y también ha sido implicada en la transmisión de patógenos bacterianos. Pulex irritans se ha confundido con la especie cercana Pulex simulans durante años. En este sentido, se identificaron los especímenes de Pulex recolectados de un zorro pampeano y un pecarí del Chaco del noroeste de la Argentina por comparación con los ejemplares tipo. Además, se investigó la presencia de Bartonella spp. y Rickettsia spp. utilizando ensayos de PCR. Nuestros resultados aportaron caracteres de importancia diagnóstica para identificar a P. irritans, que incluyen la forma del esternito VII en las hembras y del esclerito aedeagal, clasper y crochet en los machos. Además, se reporta por primera vez a P. irritans parasitando un pecarí. Este hallazgo refuerza la hipótesis del origen de esta pulga asociada con este mamífero y luego coloniza humanos y mamíferos domésticos. No hubo evidencia de ADN de Bartonella ni de Rickettsia en las pulgas analizadas.
