“…The isolation of STEC strains from drinking water supplies, collected in different municipalities in northern Paraná State, has been recently described, highlighting the importance of drinking water, especially that from untreated water supplies, as a source of STEC strains potentially pathogenic for humans 187 . Taking into account that chicken litter is very useful as an organic soil fertilizer for the production of fruits and vegetables in our settings, the detection of STEC in organic chicken fertilizer used on farms 188 also represents a significant public health safety hazard.…”

Most Escherichia coli strains live harmlessly in the intestines and rarely cause disease in healthy individuals. Nonetheless, a number of pathogenic strains can cause diarrhea or extraintestinal diseases both in healthy and immunocompromised individuals. Diarrheal illnesses are a severe public health problem and a major cause of morbidity and mortality in infants and young children, especially in developing countries. E. coli strains that cause diarrhea have evolved by acquiring, through horizontal gene transfer, a particular set of characteristics that have successfully persisted in the host. According to the group of virulence determinants acquired, specific combinations were formed determining the currently known E. coli pathotypes, which are collectively known as diarrheagenic E. coli. In this review, we have gathered information on current definitions, serotypes, lineages, virulence mechanisms, epidemiology, and diagnosis of the major diarrheagenic E. coli pathotypes.

“…According to Petkov et al (2006), application of manure storage piles obtained from infected animals often results in soil contamination with pathogenic microorganisms. It was found that pathogenic E. coli strains isolated from avian organic fertilizers can cause human infections (Puno-Sarmiento et al, 2014).…”

-The objective of the present study was to evaluate soil collected from a laying-hen farm and bird manure according to the season of the year and sampling site. Soil samples were taken at the poultry facility wall and at the distances of 15 m and 45 m from the building. Bird feces samples were collected inside the poultry house at the entrance and at ¼ and ½ length of the building. Soil and bird feces samples were evaluated by bacteriological qualitative and quantitative analyses. The largest bacterial load was determined in the samples taken at the poultry facility wall in December/January. Soil microbial contamination degree was low. The highest bacterial count in bird manure was found in the samples collected at ½ length of the hen house at the end of December/January. The qualitative study of bird feces showed the presence of E. coli bacteria all through the research period and Enterobacter spp. in the samples taken from July until September. Microbial contamination of soil environment and bird feces is most likely to be affected by winter period as at that time the highest microbial population can be determined. This fact may be linked to the prevailing climatic and microclimatic conditions.

Shiga toxin‐producing Escherichia coli (STEC) is a zoonotic pathotype associated with human gastrointestinal disease that may progress to severe complications. Ruminants, especially cattle, are the main reservoirs of STEC contaminating the environment and foods of animal or vegetable origin. Besides Shiga toxin, other virulence factors are involved in STEC virulence. O157:H7 remains the most frequent serotype associated with disease. In Brazil, the prevalence of STEC reaches values as high as 90% in cattle and 20% in meat products which may impact the Brazilian food export trade. However, only few reports are related to human disease. The stx1 gene prevails in cattle, whereas the stx2 gene is more frequent in food. Several STEC serotypes have been isolated from cattle and food in Brazil, including the O157:H7, O111:NT, NT:H19 as well as O26 and O103 serogroups. O113: H21 STEC strains are frequent in ruminants and foods but with no report in human disease. The virulence profile of Brazilian STEC strains from cattle and food suggests a pathogenic potential to humans, although some differences with clinical strains have been detected. Further studies, employing recent and more discriminative techniques are in need to better clarify their virulence potential.
