“…Similarly, this study finding was lower than the reports of Barberis et al [ 42 ] from Algeria, Thekisoe et al [ 43 ] from South Africa, Kouakou et al [ 44 ] from Ivory-Coast, Benazir et al [ 45 ] from Pakistan, Bhuiyan et al [ 40 ], and Das et al [ 46 ] from Bangladesh with a prevalence of 78.25%, 43%, 72%, 84.40%, 59.30%, and 79.38%, respectively. Besides, Owoade et al [ 19 ], Emikpe et al [ 47 ], and Mungadi et al [ 48 ] revealed higher prevalence from Nigeria with a seroprevalence of 84%, 82.7%, and 89%, respectively.…”

Avian infectious bronchitis virus is a highly contagious disease occurring in respiratory, urogenital, and reproductive tissues of chicken causing considerable losses due to death, egg drop, and reduced production. This preliminary study was conducted to investigate the prevalence of antibodies against infectious bronchitis virus (IBV) and to assess the potential risk factors in chickens of northwest Ethiopia. A cross-sectional study was conducted from November 2020 to June 2021. A total of 768 serum samples from three zones were collected. To investigate the presence of antibodies against IBV, the indirect ELISA serological test was applied. Positivity for anti-IBV antibodies was observed in 23.96% (95% CI: 20.98–27.14) of the samples. The mixed-effect logistic regression analysis of potential risk factors showed that IBV prevalence was significantly higher in young chickens than adults ( p < 0.001 ) and higher in intensive farm type than in extensive type ( p < 0.001 ). Based on the production purposes of the chickens, the odds of seropositivity for IB was significantly higher in layers than in broilers ( p < 0.001 ) and dual purposes ( p < 0.001 ). This study revealed higher seroprevalence in farms which had the “all-in-all-out” rearing method than in farms with different batches in one house with a significant difference ( p < 0.001 ), higher seroprevalence in the poor ventilated type than in good ones ( p < 0.001 ), and higher seroprevalence in the houses that did not remove used litter at all than houses of completely disposed and partially disposed litter ( p = 0.002 ). Moreover, disinfection of houses had significant effect on the occurrence of IB. Having personal protective equipment was significantly affecting the occurrence of IB, being higher in the farms that have no wearing clothes and shoe than in those having wearing clothes and shoe ( p = 0.002 ). In conclusion, the seroprevalence finding in the present study indicated that the organism is circulating among the population of chickens and high enough to cause significant economic losses Therefore, poultry houses should be cleaned, disinfected, and well ventilated and farm attendants should have separate farm shoe and clothes. Further studies on the virus isolation and molecular characterization of the target gene are needed in the study area.

“…It means that after the decline of maternal antibodies, a positive result to serological tests occurs following exposure to a wild virus. Consequently, antibodies detected in adult chickens could be considered as an indicator of infection with wild-type viruses [ 42 ].…”

“…Approximately, 2-3 ml blood was collected from the wing vein of randomly selected birds showing respiratory signs for 2 weeks using 3 ml disposable syringe. The syringe containing blood was kept in standing position for clot formation, and serum was harvested by decanting method as described by Barberis et al [22]. Later, the collected serum was taken to an eppendorf tube and transferred to laboratory maintaining cool chain and subjected to centrifuge at 3,000 rpm for 5 min for removing the remaining clots, insoluble materials, and red blood cells.…”

J Adv Vet Anim Res 2019; 6(4): ABSTRACTObjective: This study was conducted to investigate different respiratory diseases in broiler and sonali birds in some selected districts of Bangladesh. Materials and Methods:We were collected a total of 460 blood samples from 46 farms with 36 broiler farms and 10 sonali farms (cross-breed) from 2015 to 2017. All the collected serum samples were tested for determining specific antibodies of avian rhinotracheitis (ART) virus, infectious laryngotracheitis (ILT) virus, infectious bronchitis (IBV) virus, and Ornithobacterium rhinotracheale (ORT) infection using commercially available enzyme-linked immunosorbent assay kits. Results: The overall seropositivity was highest in ORT (45.9%), followed by IBV (37.6%), ART (2.6%), and ILT (0.4%). Out of 360 broiler samples, highest seropositivity was recorded in ORT (43.3%) and lowest in IBV (31.4%). Surprisingly, no broiler samples were found positive for ART and ILT. In case of sonali, the seropositivity was highest in IBV (60%) and lowest in ILT (2%). With respect to types of birds and age groups, the seropositive percentage of all four pathogens was found higher in sonali than broiler. Between two age groups of sonali, the seropositive percentage of ART (12%), ORT (55%), ILT (2%), and IBV (60%) was highest at 21-60 weeks of age compared to 5-20 weeks of age. However, based on location, the seropositive of ORT and IBV was highest in Jamalpur (63.3%) and Fulbariya and Trishal (50%) and lowest in Sreepur (16.7%) and Jamalpur (3.3%). Conclusion:The four pathogens are ubiquitous in nature for the sonali chickens, and the prevalence of ORT and IBV was the most prevalent viruses in the study areas. This study indicates a need for improved surveillance and characterization of ORT and ART circulating in all types of poultry in Bangladesh. ARTICLE HISTORY

“…The second sampling was made 10 wk later for both productive orientations in order to observe potential antibodies oscillation. And the last sampling was performed at 60 wk for layers and at 50 wk in broiler breeders, to increase the probability of finding a field strain ( Barberis et al, 2018 ). At each sampling time, for laying hens and broiler breeders 14 serum samples and 10 tracheal swabs with sterile aluminium swabs (Deltalab, Barcelona, Spain) were collected from live birds selected randomly at each flock.…”
