A total of 289 cloacal swabs from pigeons from 29 different breeders in Germany were collected. In addition, samples from pigeons exhibited at shows were collected. The detailed health status of the pigeon flocks was recorded. Samples were analysed for the presence of the recently discovered pigeon rotavirus and pigeon circovirus. Pigeon rotavirus was found in 10.3% and pigeon circoviruses was found in 65.5% of sampled pigeon lofts. The study revealed a strong relationship between the attendance of shows and the occurrence of different clinical signs. The higher prevalence of pigeon rotavirus in exhibited animals indicates that exhibitions are a risk factor for the transmission of this pathogen.

Rotavirus C (RVC) is an important cause of gastroenteritis in humans and pigs and has also been detected in cattle, ferrets, minks, and dogs. Incidental zoonotic transmissions have been described. In contrast to rotavirus A (RVA), a complete genotyping system for RVC has not yet been established due to limited or incomplete sequence data. In this study, 138 complete nucleotide sequences for VP7 (G-type) and 97 complete nucleotide sequences for VP4 (P-type) of porcine RVC-positive samples have successfully been generated and genotyped. Together with available sequences from the NCBI database, phylogenetic analyses were conducted, cut-off values were re-evaluated, and the current classification system was adapted. Pairwise identity frequency analyses revealed a new cut-off value of 82% instead of the previous 85% for the G-type and confirmed the current cut-off value of 85% for the P-type. This resulted in the identification of 21 G-types and 39 P-types, including 4 new G-types and 10 new P-types. The results of the investigations expand the existing knowledge about the genetics of RVC and demonstrate the enormous diversity of porcine RVC sequences in particular. IMPORTANCE: This article provides a new sequence data set of porcine rotavirus C (RVC) strains. The extended full-length analysis of RVC G-types and P-types enabled us to review the current classification system. According to the guidelines of the rotavirus classification working group (RCWG), the results led to a new cut-off value of RVC G-types and required the reclassification of numerous RVC G-types. In addition, several new genotypes have been found. The present work closes the aforementioned knowledge gap and provides important, comprehensive data for RVC genetic diversity.

Bovine respiratory disease (BRD) is one of the most significant health issues in cattle populations worldwide, leading to great economic losses and animal suffering

A recent study revealed that organically raised Bronze turkeys showed a high prevalence of green liver discoloration. This alteration is commonly associated with the Turkey Osteomyelitis Complex and potentially caused by opportunistic bacteria. Therefore, 360 organically fattened Bronze turkeys were examined post-mortem throughout two fattening trials with two examinations each to determine possible infectious risk factors and reduce disease prevalence. Clinical and pathoanatomical examinations were performed on every hen. Histopathological, bacteriological, parasitological, and virological examinations were performed on at least six hens without and, if applicable, six hens with green livers on each examination date. Overall, 9.0% of all hens had a green liver without a correlation with bacterial or parasitological findings but multiple health impairments. The discoloration correlated significantly with the detection of immunosuppressive turkey hemorrhagic enteritis virus at the early stage and macro- and histological joint/bone lesions at the late fattening stage, indicating the presence of two different predisposing pathogeneses. Flocks not being vaccinated against hemorrhagic enteritis but having a virus-positive sample showed the highest prevalence of green liver discoloration and developed worse in various parameters. In conclusion, an adequate vaccination schedule and the prevention of field infections may lead to a decreased risk of performance reduction and improved animal health.
