“…This study's findings indicated that IBV is widespread among backyard chickens in the studied villages, with a seroprevalence of 93.3%. This high prevalence agrees with reports from Zimbabwe (86%) (Kelly et al 1994), Switzerland (> 75%) (Keller-Berger & Hoop 1993), Bangladesh (74%) (Biswas et al 2009), central Ethiopia (91% and 97.46%) (Habte et al 2022;Shiferaw et al 2022) and Nigeria (82.95%) (Ijoma et al 2022). Relatively lower IBV seroprevalences had been recorded in Mexico (56.5%) (Gutierrez-Ruiz et al 2000), South Africa (43%) (Thekisoe et al 2003), Botswana (65.22%) (Mushi et al 2006) and north-west Ethiopia (23.96%) (Birhan et al 2021).…”

“…Subtype B was reported to circulate widely in many European countries [23]. Some zero surveillance studies were conducted among chickens in various geographical locations globally, confirming the seroconversion of some of these chickens to aMPV [27][28][29]. Our data showed that some backyard chickens in ten locations across Eastern Saudi Arabia seroconverted to aMPV (Figure -1 and Table-2).…”

Background and Aim: Avian metapneumovirus (aMPV) is a recently discovered respiratory virus in chickens. Avian metapneumovirus has been linked to respiratory syndromes, reproductive failure in affected chickens and turkeys, swollen head syndrome in chickens, and rhinotracheitis in turkeys. Wild birds are considered potential reservoirs of aMPV, particularly aMPV-C. However, little is known about the prevalence of aMPV in Saudi Arabia. Considering the relevance of backyard chickens in the transmission and sustainability of certain avian viral diseases, this study aimed to assess aMPV exposure in backyard chickens and wild birds circulating near selected locations. Materials and Methods: We collected 368 serum samples from unvaccinated backyard chickens in ten locations in Eastern Saudi Arabia. Furthermore, we collected 78 serum samples from species of free-ranging birds belonging to the Columbidae family, such as pigeons and doves, captured from the same areas. Using commercial enzyme-linked immunosorbent assay kits, we tested the sera of domestic backyard chickens and wild birds for antibodies against aMPV. Results: Our results showed that 74/368 birds were positive for aMPV-related antibodies. Conversely, none of the tested wild birds seroconverted to aMPV. Conclusion: The antibody titers detected in the backyard chickens suggested recent exposure to aMPV. Considering these results, further large-scale serological and molecular studies are needed to evaluate the prevalence of aMPV in these birds and characterize the circulating strains of aMPV in this region. Keywords: antibodies, chickens, pigeons, Saudi Arabia.

“…In this study, antibody against ND was detected in a higher proportion of the samples (68%) even though the sampled birds were not vaccinated ( Table 1 ). Similarly, antibodies were detected from unvaccinated birds located at Melekoza district of Gofa zone, 25 Sodo Zuria district; 26 Central Ethiopia; 27 Adama; 13 Buno Bedelle zone; 16 Eastern Shewa zone; 28 Wolaita zone 29 and Sebeta area. 15 This elicited the endemic nature of the disease over a wide area of the country which requires intervention to control.…”

Purpose The purpose of this research is to detect Newcastle disease virus and to assess the seropositivity among backyard, semi-intensive, and intensive farms located in central and southwestern areas of Ethiopia. Material and Methods A total of 239 oropharyngeal and cloacal swab samples were collected from symptomatic birds found in Holeta, Burayu, Jimma towns as well as Seka Chekorsa and Nadhigibe woredas of Jimma Zone. In addition, ninety blood samples were collected from wing veins of unvaccinated birds found in the study areas of Jimma zone. Side-by-side information related to risk factors estimated to contribute to the susceptibility of the disease was collected by interviewing owners of sampled birds. Reverse transcription polymerase-chain reaction (RT-PCR) was conducted to detect NDV. Likewise, Enzyme-linked immunosorbent assay (ELISA) was performed to determine the seropositivity of ND. Results The proportion of samples where NDV was detected was 24.6%. Similarly, 68.9% of the sampled birds were seropositive. It was observed that adult birds were more likely to encounter the disease than youngs (OR = 11.6; 95% CI: 4.0–33.3; P = 0.000). Birds owned by respondents who leave diseased birds in the flock were more likely infected (OR = 6.2; 95% CI: 1.8–21.2; P=0.004) as compared to those isolated and mode of disposal of dead chicken significantly affect exposure (OR = 0.13; 95% CI: 0.10–4.88; P = 0.044). Likewise, access to veterinary services highly likely reduces susceptibility to the disease (OR = 12.4; 95% CI: 3.2–46.9; P = 0.000). It was also found that birds farmed intensively were the most at risk (OR = 2.8; 95% CI: 0.58–13.71; P = 0.199). Conclusion Detection of ND from a significant proportion of sampled birds and their high seropositivity percentage revealed the circulation of the virus in the study areas.
