“…On the other hand, the presence of C. jejuni in our study and the implication of sandhill cranes as the source of a C. jejuni food-borne outbreak suggest that these migratory birds may carry human-pathogenic bacteria for long distances (8). Besides Campylobacter, pathogenic species of Salmonella and Mycobacterium have been isolated from cranes (17,34). Altogether, cranes seem to be a reservoir of many bacterial pathogens and potentially contribute a significant level of human health risk.…”

ABSTRACTWhile the microbial water quality in the Platte River is seasonally impacted by excreta from migrating cranes, there are no methods available to study crane fecal contamination. Here we characterized microbial populations in crane feces using phylogenetic analysis of 16S rRNA gene fecal clone libraries. Using these sequences, a novel crane quantitative PCR (Crane1) assay was developed, and its applicability as a microbial source tracking (MST) assay was evaluated by determining its host specificity and detection ability in environmental waters. Bacteria from crane excreta were dominated by bacilli and proteobacteria, with a notable paucity of sequences homologous toBacteroidetesandClostridia. The Crane1 marker targeted a dominant clade of unclassifiedLactobacillalessequences closely related toCatellicoccus marimammalium. The host distribution of the Crane1 marker was relatively high, being positive for 69% (66/96) of the crane excreta samples tested. The assay also showed high host specificity, with 95% of the nontarget fecal samples (i.e.,n= 553; 20 different free-range hosts) being negative. Of the presumed crane-impacted water samples (n= 16), 88% were positive for the Crane1 assay, whereas none of the water samples not impacted by cranes were positive (n= 165). Bayesian statistical models of the Crane1 MST marker demonstrated high confidence in detecting true-positive signals and a low probability of false-negative signals from environmental water samples. Altogether, these data suggest that the newly developed marker could be used in environmental monitoring studies to study crane fecal pollution dynamics.

Recent reports of natural paratuberculosis (or Johne's disease) in rabbits, foxes, and stoats has focused debate on the presence and importance of wildlife reservoirs in the epidemiology of this disease. This paper describes an extensive study investigating 18 nonruminant wildlife species for evidence of paratuberculosis. Using both culture and histopathological analysis, fox, stoat, weasel, crow, rook, jackdaw, rat, wood mouse, hare, and badger were found to harbor Mycobacterium avium subsp. paratuberculosis, the causative organism of paratuberculosis, suggesting that the epidemiology of this disease is more complex than previously realized.

“…Because the disease is progressive, tubers are often characterised by a well-defined area of central necrosis surrounded by a capsule (9,17,22,23,40). Multifocal granulomatous inflammation is severe and multifocal, with acidophilus bacilli within lesions (20,21,26,27,29,34,38,41,42,46).…”

“…Typical cases of avian mycobacteriosis in wild birds involve lack of subcutaneous and mesenteric fat accompanied by severe atrophy of pectoral muscle, characteristic white, gray or yellow nodules and hepatosplenomegally (12,21,27,29,34,41,48,52). Granulomatous lesions may be found in the lungs, spleen, intestines, bone marrow, heart, gonads, skin and joints (hepatic lesions predominating) (3,9,11,12,14,(20)(21)(22)(23)25,(27)(28)(29)36,37,40,48,52,53). Unusual lesions have included necrotic ulceration of the tongue and chronic granulomatous lesions located in the dermis around the nostrils and retro-orbital and sinus infraorbitary tissues (11,12,20,29,37).…”

Avian mycobacteriosis is important for animal and human health; wild birds play an important role in mycobacterial species' ecology and movement. This review was aimed at reporting the role of birds in the spread of avian mycobacteriosis in human and animal populations at risk and thus a systematic review was made of PubMed, Science Direct, Scielo and Scirus databases. Mycobacteria are classified into the Mycobacterium tuberculosis complex and non-tuberculous mycobacteria; the Mycobacterium avium complex represents the most important part of the latter because it is primarily responsible for mycobacterial infection in wild birds and is a potential pathogen for mammals, especially for immunocompromised patients. The clinical signs in birds are variable as it is a chronic and debilitating disease, involving emaciated carcasses, white nodules in different organs and microscopically it presents granulomatosous multifocal inflammation. Diagnosis begins by suspicion based on clinical signs and finishes with microbiological confirmation. New diagnostic techniques include testing with DNA-RNA probes. No effective treatment is currently available and chemoprophylaxis on suspicion of infection is not recommended at the start; these factors increase the potential risk of mycobacteriosis becoming one of the most frequently documented zoonotic diseases which is difficult to treat in birds and humans. Recent concern regarding mycobacterial infection lies in the increased frequency of these opportunistic infections occurring in immunocompromised individuals and these infections' potential impact on bird conservation, this being increased by greater contact between humans and wild and captive birds.
