“…The types of people known to have been infected with NDV include: laboratory workers (usually as a result of accidental splashing of infective material into the eye), veterinarians in diagnostic laboratories (presumably as a result of contact with infective material during postmortem examinations), workers in broiler processing plants and vaccination crews, especially when live vaccines are given as aerosols or fine dust. Pedersden et al (1990) reported significantly higher antibody titres to NDV in people who had known associations with poultry.…”

“…The zoonotic potential of an infectious disease agent has been inferred by comparing pathogen-specific antibody levels between individuals that are in close contact with a particular animal and a matched control population with no professional exposure to animals [17,18]. For example, a higher serum antibody level against bovine NoV was detected in large animal veterinarians compared to the general population, indicating that bovine NoV strains could infect the human population [18].…”

BackgroundNoroviruses are important enteric pathogens in humans and animals. Recently, we reported a novel canine norovirus (CaNoV) in dogs with diarrhea belonging to a new genogroup (GVI). No data are available on exposure of humans to this virus.MethodsSera from 373 small animal veterinarians and 120 age-matched population controls were tested for IgG antibodies to CaNoV by a recombinant virus like particle based enzyme-linked immunosorbent assay.ResultsAntibodies to CaNoV were found in 22.3% of the veterinarians and 5.8% of the control group (p < 0.001). Mean corrected OD450 values for CaNoV antibodies were significantly higher in small animal veterinarians compared to the control group.ConclusionsThese findings suggest that CaNoV may infect humans and small animal veterinarians are at an increased risk for exposure to this virus. Additional studies are needed to assess if this virus is able to cause disease in humans.

Gumboro Disease (IBD) caused by Infectious Bursal Disease Virus is an immunosuppressive condition of chickens, which resulted in severe economical losses. Approximately 47 years after the first appearance of the disease, the changes in the form of presentation and pathogenicity of IBDV in the field has resulted in continual changes and adjustments of the vaccines used to control IBD. The original form of the disease, also known as classic or clinical IBD, was usually observed after the third week of life with high mortality, depending on factors, such as virulence of the strain of virus involved, age of the birds and maternal antibody status. The acute IBD is caused by the very virulent IBDV strains, characterized by high mortality rates in vaccinated chickens and the clinical signs and lesions are similar to those of the classic form. The subclinicalform of the disease is associated with the "variant" strains of IBDV and is characterized by low mortality and severe immunosuppression. Initially, the classic IBD was controlled by the use of mild vaccines produced in the early 1970s and from the late 1980s revealed absence of protection from wIBDV in vaccinated chickens. Another group of vaccinal strains, known as intermediate plus vaccine, has been used to control wIBDV strains. These vaccines multiply in birds, even in the presence of high maternal antibody titers. In the USA and other countries, the disease from the variant strains was controlled by intermediate strains as well as by inactivated vaccines that included variant strains, thus providing maternal antibodies against both the standard and variant strains. Until today, the IBD continues to pose an important threat to commercial poultry industry. The high resistence of IBDV to physical and chemical agents accounts for persistence of the virus in the outside environment, particularly on contaminated farms, despite disinfection. Nevertheless and not quite unexpected for the IBDV mutations in the genome, resulted in the emergence of antigenic variant strains in vaccinated flocks. The IBD requires heightened vigilance and the incidence and prevalence of the clinical and immunosuppressive forms must be evaluated more precisely.
