Evidence of Mycoplasma spp. transmission by migratory wild geese.


ABSTRACT: Mycoplasma infections have been found in different species of waterfowl worldwide. However, the question of how the pathogens have been transmitted and dispersed is still poorly understood. Samples collected from clinically healthy greater white-fronted geese (Anser albifrons) (N = 12), graylag geese (Anser anser) (N = 6), taiga bean geese (Anser fabalis) (N = 10), and barnacle geese (Branta leucopsis) (N = 1) were tested for Mycoplasma spp. All Mycoplasma-positive samples were specified by species-specific PCR for Mycoplasma anserisalpingitidis (formerly known as Mycoplasma sp. 1220), M. anseris, M. anatis, and M. cloacale. The presence of Mycoplasma spp. was confirmed in 22 of 29 sampled birds (75.9%). Mycoplasma anserisalpingitidis was the most frequently detected species (15 of 22, 68.2%). However, we did not detect any of the other Mycoplasma spp. typical for geese, among which are M. anatis, M. anseris, and M. cloacale. Phylogenetic analysis revealed that Polish sequences of M. anserisalpingitidis formed a distinct branch, along with 2 Hungarian isolates obtained from domestic geese. Eight of the samples identified as Mycoplasma spp.-positive were negative for the aforementioned Mycoplasma species. A phylogenetic tree constructed based on partial 16S rRNA gene analysis showed that Mycoplasma spp. sequences collected from Polish wild geese represent a distinct phylogenetic group with Mycoplasma sp. strain 2445 isolated from a domestic goose from Austria. The results of our study showed that wild geese could be a reservoir and vector of different species of the Mycoplasma genus that can cause significant economic losses in the domestic goose industry.
