“…Moreover, the lesions in the myocardium are similar, although less severe, to those reported in turkey poults and broiler breeder chick infected by a reovirus (12). Reoviruses are also known to induce atrophy of lymphoid tissues, especially of the cloacal bursa (4,7,10). Lymphoid depletion and lymphocytolysis were obvious in our case, not only in the cloacal bursa but also in the thymus and spleen.…”

“…Due to suspicion of chicken reovirus infection an attempt was made to isolate the virus in chicken embryo kidney cells (CEKs). Meanwhile, Liu et al (2011) conducted experimental reovirus infection in Pekin ducks but failed to re-isolate the virus, as was achieved in our study. Chen et al (2012) successfully isolated reovirus from experimentally infected ducks but all birds died at 48-72 h.p.i.…”

During the summer 2012 an incidence of high mortality, above 44 percent, in two flocks of Muscovy ducklings in Poland was noted. The clinical signs included considerable weight loss and inability to walk.During the post-mortem evaluations dehydration and enteritis, gouty kidneys as well as hemorrhagic liver and spleen lesions were found. The laboratory diagnosis included agar gel precipitation assay (AGP) as well as polymerase chain reaction (PCR) or reverse transcription PCR for the presence of goose parvovirus (GPV), duck circovirus (DuCV), duck reovirus (DRV) and avian reovirus (ARV). Interestingly, the examinations performed by AGP showed partial reactivity of liver homogenates from Muscovy ducklings with chicken S1133 antiserum. The presence of duck reovirus RNA was also detected by real-time RT-PCR targeting the chicken reovirus sigma NS fragment, while the sequencing showed major similarity to chicken S1133, 1733, GX/2010/1 and TARV-MN2 reovirus strains. The virus sequence was also related to a previously isolated TH11 strain from Muscovy ducks in China.Further study is needed in order to explain the particular epidemiology of the reovirus infection of Muscovy ducklings.

“…Novel duck reovirus (NDRV) belongs to the genus orthoreovirus in the family Reoviridae , which includes many viruses, not least the rotavirus, which is a major human pathogen. As observed in China's Fujian, Guangdong, and Zhejiang Provinces, NDRV disease, which caused loss of appetite, unstable gait, diarrhea, and death in various species of ducks (Liu et al, 2011). This disease has been as prevalent as other traditional epidemic diseases, such as avian influenza, duck plague, and ducks Tembusu virus.…”

Dietary Administration of Bacillus subtilis Enhances Growth Performance, Immune Response and Disease Resistance in Cherry Valley Ducks

et al. 2016

Given the promising results of applying Bacillus subtilis (B.subtilis) as a probiotic in both humans and animals, the aim of this study was to systematically investigate the effects of B. subtilis on growth performance, immune response and disease resistance in Cherry Valley ducks. At 28 d post-hatch (dph), ducks fed a diet with B. subtilis weighed significantly more, had higher relative immune organ weights (e.g., bursa of Fabricius, thymus, and spleen), and exhibited greater villus heights, villus height to crypt depth ratios (duodenum and jejunum), and shallower crypt depths in the duodenum than controls fed a normal diet (p < 0.05). Moreover, the major pro-inflammatory factors and antiviral proteins, as measured in the thymus and the spleen, were higher at 28 dph in ducks fed probiotics than those of 14 dph. After 28 d of feeding, the ducks were challenged with Escherichia coli (E. coli) and novel duck reovirus (NDRV), and ducks fed B. subtilis achieved survival rates of 43.3 and 100%, respectively, which were significantly greater than the control group's 20 and 83.3%. Altogether, diets with B. subtilis can improve Cherry Valley ducks' growth performance, innate immune response, and resistance against E. coli and NDRV.
