“…Strict anaerobes, such as Clostridium , are part of the normal microbiota of the alimentary tract of chickens (Barrow 1994). Although this may also be the case for wild birds, information about these bacteria is mainly restricted to reports of intestinal anaerobes with lethal effects on hosts (Asaoka et al 2004, Hagen and Bildfell 2007). However, we detected no strict anaerobes in cloacal samples.…”

Bacteria grow on avian eggshells and thus can potentially cause diseases in developing embryos. Little is known about culturable bacteria colonizing avian eggshells in free‐living birds, with most studies restricted to poultry. Our objective was to examine the culturable bacterial array growing on eggshells during incubation that could negatively affect hatching success of Pied Flycatchers (Ficedula hypoleuca) in a temperate montane habitat in central Spain. Cloacal culturable bacteria of females were also analyzed because bacteria can be vertically transmitted from females to eggs. We used fecal samples as surrogates of cloacal samples due to the small size of sampled birds. We found that eggshells and female cloacae of Pied Flycatchers harbored 24 and 40 bacterial families and species, respectively, but only a few in each clutch and each cloaca. Rod‐shaped gram‐negative bacteria and bacteria in the family Pseudomonadaceae were the most common bacteria on eggshells during early and late incubation and in female cloacae. Although based on small sample sizes, we found that females with rod‐shaped gram‐negative bacteria in their cloacae laid eggs that also had these bacteria, providing possible evidence for vertical transmission. We found no evidence for vertical transmission of Pseudomonadaceae, suggesting a possible environmental source for these bacteria. The prevalence of bacterial morphological types and major taxonomical categories on eggshells did not vary from early to late stages of incubation, providing support for the hypothesis that incubation may have bacteriostatic effects on bacterial proliferation on eggshells. Despite being primary egg invaders in poultry, we detected no effects of culturable Pseudomonadaceae or Pseudomonas luteola on hatching success. Our study represents the first to examine the culturable bacteria growing on the eggshells of a wild bird in a temperate habitat and additional studies based on culture‐independent techniques are required to confirm our results.

“…Bacteria and fungi can also occur in sage-grouse (Scott, 1940;Honess, 1968;Hausleitner, 2003;Connelly and others, 2004;Peterson, 2004;Hagen and Bildfell, 2007;Christiansen, 2011), but none currently play a role in limiting sage-grouse populations. This may change if environmental conditions result in greater concentrations of birds, leading to contamination of water supplies with fecal material (Christiansen, 2011).…”

“…The main sources of this bacterium are healthy birds’ digestive contents, soil, dust, poultry litter, and animal faeces [ 47 ]. C. perfringens has been isolated from many bird species, such as ducks [ 48 , 49 ], wild crows [ 50 ], western bluebirds [ 51 ], ostriches [ 52 ], greater sage-grouses [ 53 ], pheasants [ 54 ], and capercaillies [ 55 ]. Moreover, once infected, the birds can transmit pathogens by dropping contaminated feces, which becomes a significant risk factor for illness among individuals and domestic animals.…”

Birds that roam freely, particularly those that migrate, have the potential to carry a range of diseases that can be passed on to humans. The vast movement of these birds across diverse environments and urban areas can contribute to the spread of bacteria over long distances, impacting both human and animal populations. Stress, overcrowding, and human interaction can also play a role in the transmission of infectious diseases among birds and humans. Therefore, it is crucial to comprehend the intricate connections between birds, vectors, zoonotic pathogens, and the environment, especially given the increasing urbanization and emergence of zoonotic illnesses. This review aims to provide a systematic overview of the significance of avian species in transmitting bacterial pathogens that pose a risk to public health.
