“…Thus, a reptilian reservoir for the Panama serovar is plausible, as it is found in frogs, toads, turtles, lizards, and snakes, 6,15,16 and the host range might be much larger because of its presence in wild birds, swine, poultry, and Indian mongooses. [17][18][19][20][21] In our study, Arechavaleta was the second most important serovar.…”

A retrospective study was conducted to identify the risk factors associated with bacteremia in infants and children in Guadeloupe, French West Indies. The 171 patients with infection seen between 2010 and 2014 included 155 (90.6%) with acute gastroenteritis, of whom 42 (27.1%) had concomitant bacteremia, and 16 (9.4%) with primary bacteremia. Most cases (97.7%) were in infants and children with no underlying health condition. Two subspecies were recovered: ( = 161, 94.2%) and ( = 10, 5.8%). All but one (serovar Typhi) were non-typhoidal . The most common serovars were Panama ( = 57, 33.3% of isolates) and Arechavaleta ( = 28, 16.4%). Univariate analysis showed a strong association only between age > 6 months and infection with the Panama or Arechavaleta serovar ( = 0.002). The rate of resistance to all classes of antibiotics during the study period was low (< 15%); however, the detection of one extended-spectrum beta-lactamase-producing strain highlights the need for continued monitoring of antimicrobial drug susceptibility. Infection with Panama ( < 0.001) or Arechavaleta ( < 0.001) serovar was significantly associated with bacteremia in a multivariate analysis. These serovars are probably poorly adapted to humans or are more virulent. A delay between onset of symptoms and hospital admission > 5 days ( = 0.01), vomiting ( = 0.001), and increased respiratory rate ( = 0.001) contributed independently to bacteremia in the multivariate analysis. Thus, if non-typhoidal infection is suspected, blood should be cultured and antibiotic treatment initiated in all patients who meet these criteria.

“…Illegal wildlife trade might have influenced the findings here described, as it contributes to a closer contact between wild and domestic species, in addition to humans (Kruse et al 2004). Trafficked wild birds are potential reservoirs of important agents of human health (Matias et al 2016). Thus, measures, such as quarantine, are essential for avoiding the spread of strains with zoonotic potential.…”

Molecular diagnosis of diarrheagenic Escherichia coli isolated from Psittaciformes of illegal wildlife trade

et al. 2018

Diarrheagenic Escherichia coli (DEC) are considered one of the major causes of human diarrhea in developing countries. Some studies have pointed wild birds as important reservoirs for these pathogens. However, scarce species from the Psittaciformes order have been investigated. This study aimed to evaluate the presence of DEC strains in Psittaciformes from illegal wildlife trade. A total of 78 E. coli strains isolated from cloacal swab samples of 167 Psittaciformes in the Ceará State, Brazil, were evaluated regarding the presence of the following DEC virulence genes by polymerase chain reaction (PCR): eaeA and bfpA genes (Enteropathogenic E. coli - EPEC); stx1 and stx2 (Shiga toxin-producing E. coli - STEC); estA and eltB (Enterotoxigenic E. coli - ETEC); ipaH (Enteroinvasive E. coli - EIEC); aatA and aaiC (Enteroaggregative E. coli - EAEC). Positive strains for eaeA and bfpA genes were considered typical EPEC, while strain positive exclusively for the eaeA gene were classified as atypical EPEC. The eaeA gene was identified in 20 E. coli strains and bfpA in 22 isolates. In addition, 11 and 9 belonged to tEPEC and aEPEC, respectively. No strain was positive for stx1 or stx2. A total of 47 (60.3%) strains and a total of 136 birds (81.4%) were negative for the remaining DEC pathotypes investigated. In conclusion, psittacine from illegal wildlife trade in Ceará State, Brazil, presented a relevant prevalence of typical and atypical EPEC, potentially playing a role as reservoirs of DEC strains in the environment. Thus, proper control measures must be adopted to block the spread of these pathogens.

“…Although Salmonellae are usually known as foodborne pathogens, water could be a potential mode of transmission. Salmonella can be found in the feces of a large variety of vertebrates, including humans, reptiles, birds, farm and wild animals (Matias et al, 2016;Silva et al, 2014).…”

a b s t r a c tFecal indicator bacteria, such as Escherichia coli (E.coli) and Enterococcus, have been widely used to indicate the presence of pathogens. However, the suitability of fecal indicator bacteria to represent health risks is still being challenged, particularly in tropical aquatic environments. The objective of this study is to understand the occurrence and prevalence of indicators and pathogens in areas with contrasting land use, as well as to identify the major correlations between indicators, pathogens and environmental parameters. The spatial and temporal variation of indicators and pathogens was studied to examine the distribution patterns for areas with different land use, and the impact of seasonal changes on microbial populations. A total of 234 water samples were sampled for two years from reservoirs and their tributaries, and tested for fecal indicator bacteria, coliphages, human specific markers, pathogenic bacteria and viruses. The prevalence of indicators and pathogens in reservoirs were generally low, while relatively high concentrations were observed in tributaries to varying degrees. Of the enteric viruses, norovirus GII was among the most prevalent and had the highest concentration. Although strong correlations were found between indicators, only relatively weak correlations were found between indicators and pathogens. The results in this study showed that none of the bacteria/phage indicators were universal predictors for pathogens. Inclusion of the alternative indicators, Methanobrevibacter smithii, Bacteroides and human polyomaviruses (HPyVs) to monitoring programs could help to determine whether the fecal source was human. The microbial distribution patterns allow the classification of sampling sites to different clusters and thus, help to identify sites which have poor water quality. This approach will be useful for water quality management to pinpoint factors that influence water quality and help to prioritize sites for restoration of water quality.
