“…Although infection by C. parvum is not common among birds, Zylan et al (2008) (VAN ZEELAND et al, 2008;MOLINA-LÓPEZ et al, 2010;COLDWELL et al, 2012;LEY et al, 2012;BOUGIOUKLIS et al, 2013;BAINES et al, 2014), and of domesticated birds, such as domestic chickens (BLAGBURN et al, 1991), geese (Anser anser f. domestica) (CHVALA et al, 2006), turkeys (GLISSON et al, 1984), ducks (MASON, 1986;O'DONOGHUE et al, 1987), peacocks (MASON & HARTLEY, 1980) and pheasants (RANDALL, 1986).…”

Cryptosporidiosis is one of the main protozoan infections in birds. It manifests as either a respiratory or a digestive illness, and it affects a very large number of avian species across several continents. The aim of this review is to report on the main results of studies on cryptosporidiosis among birds and the importance of these results to veterinary medicine and public health.Keywords: Cryptosporidium spp., wild birds, poultry. ResumoA criptosporidiose constitui-se em uma das principais infecções por protozoários em aves, manifestando-se como enfermidade respiratória ou digestiva, em dezenas de espécies aviárias, em vários continentes. O objetivo desse trabalho foi relatar, por meio de revisão de literatura, os principais resultados de estudos sobre criptosporidiose em aves e sua importância para a medicina veterinária e saúde pública.Palavras-chave: Cryptosporidium spp., aves selvagens, aves domésticas.

“…Recently, respiratory cryptosporidiosis has been diagnosed in wild birds: the American Cliff Swallow Petrochelidon pyrrhonota, a colonially nesting species, where infection was concurrent with infection by Mycoplasma sturni (Ley et al 2012), and in 2010 in the Red Grouse Lagopus lagopus scotica (the UK subspecies of Willow Ptarmigan) in northern England, with clinical diagnoses of infection from C. baileyi (Coldwell et al 2012). The Red Grouse is a wild gamebird that has approximately doubled in post-breeding density on moors managed for grouse shooting across northern England over the last 5-10 years (Baines et al 2016).…”

Respiratory cryptosporidiosis was first diagnosed in Red Grouse Lagopus lagopus scotica, the UK subspecies of Willow Ptarmigan, in 2010. In the next 3 years, respiratory infection by Cryptosporidium baileyi had manifested itself in Grouse on half the moors in northern England and 80% of moors in the North Pennine Hills. In this first account of the impact of respiratory cryptosporidiosis on the population dynamics of a wild bird we fitted 111 diseased and 67 healthy Grouse with radio‐transmitters at two North Pennine moors where disease prevalence averaged 8.1% and monitored their survival and fecundity between autumn 2013 and autumn 2015. Six‐month natural survival rates (excluding shooting) were 0.70 in healthy Grouse, but only 0.44 in diseased females, and 0.22 in diseased males. Some 39% of diseased birds died from their infection, whereas 28% of healthy birds were shot. A similar proportion of each group were killed by predators, either by Stoat Mustela erminea or raptors. Diseased females bred 8 days later than healthy females, but clutch size, egg volume and nesting success did not differ in relation to disease status. Productivity was 43% lower among pairs with a diseased member than in healthy pairs, but appeared impaired only if the female was diseased, not the male. Differences in productivity were related to chick survival rather than the proportion of pairs that reared broods, with chick survival being lower in the 10 days after hatching and again when chicks were 20–50 days old. This latter period was when respiratory infection among chicks was first noticed and the onset of infection may have been a contributing factor to higher mortality during this period. Described levels of respiratory infection reduced the number of birds available to shoot in August by 6%, which represented a mean annual loss of £0.9 million in revenue across managed grouse moors. Likely reductions in shoot economics could escalate should prevalence increase. This disease is a welfare concern and potentially a conservation concern, too, should infection cross to other bird species occupying the same moors.

“…Another Mycoplasma species that can cause conjunctivitis is Mycoplasma sturni , but its host range is limited to only wild birds. Mycoplasma sturni was identified for the first time in a European starling ( Sturnus vulgaris ) with severe bilateral conjunctivitis 19 and also isolated from other passerine species such as the northern mockingbird ( Mimus polyglottos ), blue jay ( Cyanocitta cristata ) 20 , house finch ( Haemorhous mexicanus ) 21 , cliff swallow ( Petrochelidon pyrrhonota ) 22 , American crow ( Corvus brachyrhynchos ), and American robin ( Turdus migratorius ) 23 . All these species of birds showed clinical signs comparable to those present in the European starling.…”

Different Mycoplasma species have been reported in avian hosts. However, the majority of studies focus on one particular species of Mycoplasma or one host. In our research, we screened a total of 1141 wild birds representing 55 species, 26 families, and 15 orders for the presence of mycoplasmas by conventional PCR based on the 16S rRNA gene. Selected PCR products were sequenced to perform the phylogenetic analysis. All mycoplasma-positive samples were tested for M. gallisepticum and M. synoviae, which are considered the major pathogens of commercial poultry. We also verified the influence of ecological characteristics of the tested bird species including feeding habits, habitat types, and movement patterns. The presence of Mycoplasma spp. was confirmed in 498 birds of 29 species, but none of the tested birds were positive for M. gallisepticum or M. synoviae. We found possible associations between the presence of Mycoplasma spp. and all investigated ecological factors. The phylogenetic analysis showed a high variability of Mycoplasma spp.; however, some clustering of sequences was observed regarding particular bird species. We found that wild migratory waterfowl, particularly the white-fronted goose (Anser albifrons) and mallard (Anas platyrhynchos) could be reservoirs and vectors of mycoplasmas pathogenic to commercial waterfowl.
