Detection of enteropathogenic bacteria and enteroparasites in patients with acute diarrhea in Juruti, Pará, Brazil/Detecção de bactérias enteropatogênicas e enteroparasitas em pacientes com diarreia aguda em Juruti, Pará, Brasil
With the aim of determining the frequency rate of enteropathogenic bacteria and enteroparasites in patients with acute diarrhea in the Municipality of Juruti, Pará State, which has been facing an intense migratory process due to a great mining project, we analyzed 263 cases of acute diarrhea. A total of 19 percent of those cases were related to enteropathogenic bacteria, particularly Shigella spp. that accounted for 13.7 percent of the cases. Salmonella spp, Aeromonas spp and Plesiomonas shigeloide were also detected. The most frequent Shigellaserotypes found were S. flexneri (61.1 percent) and S. sonnei (38.9 percent). Among the Salmonella, we could observe the following serotypes S. Panama (2), S. Newport (2), S. Bredeney, S. Saintpaul and S. Gaminara. The infection caused by protozoa reached 85.3 percent, mostly due to Blastocystis hominis (37.3 percent), Entamoeba histolytica/E. dispar (22.8 percent), Endolimax nana (16.7 percent), Entamoebacoli (9.5 percent) and Giardia lamblia (8.4 percent). These results provide valuable data to epidemiological and environmental surveillance because it presents the unsatisfactory basic sanitary conditions of the local population.(AU)
