“…Affected birds usually died within 12 to 24 h from onset of vomiting, with deaths continuing for about seven days [ 2 ]. Gross pathological lesions were: mildly enlarged, diffusely mottled or congested livers and sometimes enlarged, friable and mottled spleens and in some cases pale kidneys [ 2 , 7 ]. For racing pigeon breeders, rotavirus is important mainly during the young pigeon racing season, when it significantly affects their performance, including the number of pigeons that do not return to the loft [ 4 , 5 ].…”

Background Pigeon Rotavirus A (RVA) infection has been confirmed in pigeons in the last decade as a cause of Young Pigeon Disease (YPD). Although YPD has been known for many years to date, no studies have been conducted to track the spread of RVA infection in pigeons during the racing season. The presented research aims to determine the course of RVA infection during the flights of young racing pigeons in the summer season, in one of the districts in the Mazovian Voivodeship in Poland. Results Faecal samples of pigeons collected from transport baskets in vehicles transporting pigeons to the starting point were tested. The quantitative RT-PCR (qRT-PCR) was used to detect the genetic material of RVA. Samples taken during 6 flights were analysed. The study showed a percentage increase in infections up to the fourth flight of pigeons, and then their decrease. With Cq values below 20, breeders did not participate in the next flight and/or reported disease in the flock. With positive Cq values of 20 to 30, clinical signs of disease were not reported. Of the 76 breeders participating in the races, at least one positive result was found in 46 (60.5%). Including the occurrence of the disease during the racing season was reported by 11 breeders (14.4%). The main clinical signs in sick pigeons were vomiting, diarrhea and stowed crop. The tested pigeons were not vaccinated against RVA. Conclusions During training and racing of pigeons, it is not possible to avoid exposing them to pathogens, including RVA, regardless of whether pigeons from different breeders are placed in the same baskets or are in separate baskets. However, after four flights the number of new cases of the disease decreases which indicates the development of immunity. The qRT-PCR test is useful in the diagnosis and differentiation of clinical (Cq below 20) and subclinical RVA infections in racing pigeons.

Rotaviruses are well‐recognized pathogens responsible for diarrhea in humans and various animal species, with Rotavirus A the most often detected and most thoroughly described. Rotaviral disease is an important concern in pathology of pigeons as well, as pigeon rotavirus A was proven to play a major role in young pigeon disease (YPD). However, rotaviruses of other groups have been so far understudied in birds. This paper describes the first finding of Rotavirus G in domestic pigeon in Europe, as well as the recovery of three complete genomes of pigeon rotavirus A with Oxford Nanopore Sequencing. Quantification of pigeon rotavirus A genetic material with droplet digital polymerase chain reaction (PCR) in pigeons suffering from diarrhea and in asymptomatic pigeons was also performed in the frameworks of this study and resulted in determination of statistically highly significant differences between the groups in both detection rate and shedding of the virus. Phylogenetic analysis revealed the close relationship of acquired strains with those originating from pigeons from Europe, North America, Asia, and Australia, indicating a broad geographical spread of pigeon rotaviruses. Results of our research shed more light on occurrence and diversity of Rotavirus species in pigeons.
