“…Serological testing demonstrated AIV antibodies and AIV antibodies of subtype H9, however no AI viral RNA was detected. These findings are similar to reports in captive wild birds in Nigeria (10.4% sero-prevalence) [ 29 ] and Ohio zoos (2006 to 2009, 11.9%) [ 30 ], in Little Egrets and Black-crowned Night Herons at a city park in Jiangxi, China (6.0% H9) [ 31 ]. A previous study in Bangladesh reported the detection of AIV H5 subtype in resident and migratory wild birds, which might be due to the possibility of mixing of different bird species in wild condition [ 32 ].…”

Avian influenza (AI) is endemic and frequently causes seasonal outbreaks in winter in Bangladesh due to high pathogenic avian influenza (HPAI) H5N1 and low pathogenic avian influenza (LPAI) H9N2. Among avian influenza A viruses (AIV), H5, H7, and H9 subtypes have the most zoonotic potential. Captive birds in zoos and safari parks are used for educational, recreational, breeding, and conservational purposes in Bangladesh. To screen for AIV in captive birds to assess potential public health threats, we conducted a cross-sectional study in two safari parks and one zoo in Bangladesh for four months, from November to December 2013 and from January to February 2014. We collected blood samples, oropharyngeal, and cloacal swabs from 228 birds. We tested serum samples for AIV antibodies using competitive enzyme-linked immunosorbent assay (c-ELISA) and AIV sero-subtype H5, H7, and H9 using hemagglutination inhibition (HI) test. Swab samples were tested for the presence of avian influenza viral RNA using real-time reverse transcription-polymerase chain reaction (rRT-PCR). Across all the samples, AIV antibody prevalence was 9.7% (95% CI: 6.1–14.2, n = 228) and AIV HA subtype H5, H7 and H9 sero-prevalence was 0% (95% CI: 0–1.6, n = 228), 0% (95% CI: 0–1.6, n = 228) and 6.6% (95% CI: 3.72–10.6, n = 228), respectively. No AI viral RNA (M-gene) was detected in any swab sample (0%, 95% CI: 0–1.6, n = 228). Birds in the Safari park at Cox’s Bazar had a higher prevalence in both AIV antibody prevalence (13.5%) and AIV H9 sero-prevalence (9.6%) than any of the other sites, although the difference was not statistically significant. Among eight species of birds, Emu (Dromaius novaehollandiae) had the highest sero-positivity for both AIV antibody prevalence (26.1%) and AIV H9 prevalence (17.4%) followed by Golden pheasant (Chrysolophus pictus) with AIV antibody prevalence of 18.2% and AIV H9 prevalence of 11.4%. Our results highlight the presence of AI antibodies indicating low pathogenic AIV mingling in captive birds in zoos and safari parks in Bangladesh. Continuous programmed surveillance is therefore recommended to help better understand the diversity of AIVs and provide a clear picture of AI in captive wild birds, enabling interventions to reduce the risk of AIV transmission to humans.

“…Ingestion of contaminated faeces by scavenging chickens reared locally seems to be the major exposure route of IBV infection. It has been observed that local chickens which are kept under extensive management systems have access to both humans and animal (both domestic and wild) wastes during their search for food (Daodu et al, 2020). The result of this could have been precipitated frequent underreported IBV cases revealed in our interview.…”

“…Birds produced under these conditions, have a high mortality, that is why indigenous chickens have low productivity as a result of accidents, predation and diseases [14]. High prevalence of diseases is one of the principal limitations to these production systems [15]. Smallholder farmers and those in peri-urban areas are resource constrained, finance included, have limited access to veterinary services, information about the prevention and treatment of animal diseases, as well as prophylactic and therapeutic veterinary medicines [16].…”

Most resource-constrained smallholder farmers rely on ethnoveterinary medicine to treat village chicken diseases. An in-depth literature review and empirical study was conducted to establish ethnoveterinary practices used in indigenous chicken health management. The study showed that most village chicken farmers were female (70%). Most farmers kept chickens for socio-economic purposes; food, status and income. Common birds’ ailments treated and controlled using EVPs include Fowl Cholera; Pullorum; Diarrhea; Gumboro; Avian Influenza; Ngorok & Snot (Infectious Coryza); Bloody & watery diarrhea (Coccidiosis). Variety of materials were used to treat and control chicken diseases either as purely indigenous methods or in combination with conventional medicines. Among the practices, medicinal plants like Aloe vera emerged as the most commonly used botanical plant. More so, both literature and the empirical study, showed that farmers prepared and applied A. vera uniquely depending on the region and type of A. vera. Majority of remedies are used to treat more than one ailment. It is recommended that these practices be preserved and considered for new drug advancement and commercialization to promote cheaper and environmentally friendly options for poultry health management.
