“…Infections are also associated with septicaemia and haemorrhagic enteritis in psittacines (Rich, 2003), corneal ulcers in captive cranes (Miller et al , 1995) and mass mortality in free‐living flamingos (Kock et al , 1999). Different strains of Streptococcus and Enterococcus species have also been isolated from birds in association with septicemic disease (Devriese et al , 1995, 1992, 1991; Droual et al , 1997; Farrow & Collins, 1985). Staphylococcosis is a relatively common disease of domestic poultry, particularly turkeys, resulting in osteomyelitis, arthritis, tendonitis, and occasionally septicemia (Gross, 1978).…”

Bacterial pathogens in wild birds: a review of the frequency and effects of infection

The importance of wild birds as potential vectors of disease has received recent renewed empirical interest, especially regarding human health. Understanding the spread of bacterial pathogens in wild birds may serve as a useful model for examining the spread of other disease organisms, both amongst birds, and from birds to other taxa. Information regarding the normal gastrointestinal bacterial flora is limited for the majority of wild bird species, with the few well-studied examples concentrating on bacteria that are zoonotic and/or relate to avian species of commercial interest. However, most studies are limited by small sample sizes, the frequent absence of longitudinal data, and the constraints of using selective techniques to isolate specific pathogens. The pathogenic genera found in the gut are often those suspected to exist in the birds' habitat, and although correlations are made between bacterial pathogens in the avian gut and those found in their foraging grounds, little is known about the effect of the pathogen on the host, unless the causative organism is lethal. In this review, we provide an overview of the main bacterial pathogens isolated from birds (with particular emphasis on enteropathogenic bacteria) which have the potential to cause disease in both birds and humans, whilst drawing attention to the limitations of traditional detection methods and possible study biases. We consider factors likely to affect the susceptibility of birds to bacterial pathogens, including environmental exposure and heterogeneities within the host population, and present probable avenues of disease transmission amongst birds and from birds to other animal taxa. Our primary aim is to identify gaps in current knowledge and to propose areas for future study.

“…Common enterococcal infections include those of the urinary tract, bloodstream, endocardium and wounds (Shepard & Gilmore, 2002). Although relatively rare, infections by Enterococcus faecalis (Chadfield et al, 2004), Enterococcus hirae (Chadfield et al, 2005), Enterococcus durans (Abe et al, 2006) and Enterococcus cecorum (Stalker et al, 2010) have been described in poultry, and in other birds such as canaries and psittacines (Devriese et al, 1990(Devriese et al, , 1995.…”

Molecular characterization of vancomycin-resistant enterococci and extended-spectrum β-lactamase-containingEscherichia coliisolates in wild birds from the Azores Archipelago

et al. 2011

To study the prevalence of vancomycin-resistant enterococci (VRE) and extended-spectrum b-lactamase (ESBL)-containing Escherichia coli isolates, and the mechanisms of resistance implicated, 220 faecal samples from wild birds were collected between 2006 and 2010 in the Azores Archipelago. Samples were spread on SlanetzÁBartley agar plates supplemented with 4 mg/l vancomycin and on Levine agar plates supplemented with 2 mg/l cefotaxime for VRE and ESBL-containing E. coli isolation, respectively. vanA-containing enterococcal isolates (four Enterococcus faecium and two Enterococcus durans) and vanC-1 Enterococcus gallinarum isolates were detected in six and seven faecal samples, respectively. VRE isolates showed ampicillin (n 011), ciprofloxacin (n 09), tetracycline (n06), erythromycin (n 05), quinupristin/dalfopristin (n 03) and high-level kanamycin resistance (n 01). The tet(L) and/or tet(M) gene was found in all tetracycline-resistant isolates and the erm(B) gene in all erythromycin-resistant isolates. Three vanAcontaining E. faecium and two E. gallinarum presented specific sequences of the Tn5397 transposon. Four VRE isolates harboured the ace virulence gene. One faecal sample revealed one ESBL-containing E. coli isolate that belongs to the A phylogenetic group, showed a phenotype of resistance to b-lactams and tetracycline, and harboured the bla CTX-M-14 , bla SHV-12 and the tet(A) genes. To our knowledge, this is the first study to focus on defining the prevalence of VRE and/or ESBL-containing E. coli strains in wild birds from the Azores. The data recovered are essential to improve knowledge about the dissemination of resistant strains through wild ecosystems and their possible implications by transferring these resistances to other animals or to humans.
