Title: Detection of Paragonimus mexicanus (Trematoda) metacercariae in crabs from Oaxaca, Mexico. Author: Vargas-Arzola J, Segura-Salvador A, Reyes-Velasco L, Díaz-Chiguer DL, Márquez-Navarro A, León-Avila G, Ibañez-Cervantes G, Camacho AD, Sánchez-Manzano RM, Nogueda-Torres B. Journal: Acta Trop; 2014 Sep; 137():95-8. PubMed ID: 24836918. Abstract: Metacercariae of Paragonimus mexicanus were collected in crabs Tehuana guerreroensis (Rathbun, 1933) in the municipality of Putla, Oaxaca, Mexico. Metacercariae were found in 20.8% of the crabs collected, with an average of 1.9 metacercarie per crab. Stained metacercariae showed the specific characteristics of P. mexicanus by morphology and sequencing a fragment of the 28S ribosomal gene obtained by PCR. These findings reveal that T. guerreroensis is an intermediate host for P. mexicanus; this new report is relevant considering the potential risk of transmission in the states of Oaxaca and Guerrero, Mexico.[Abstract] [Full Text] [Related] [New Search]
