RESUMEN
A systematic review was conducted to summarize and synthesize the existing research on poultry farmers' knowledge, practices, and awareness regarding antimicrobial use (AMU) and antimicrobial resistance (AMR). It was undertaken by systematically searching databases, screening and characterizing relevant studies, extracting data, and evaluating the risk of bias. The outcomes were stratified into several subgroups, and pooled prevalence of each subgroup was calculated using a random-effect meta-analysis. Meta-regression was used for selected outcomes to further investigate the potential sources of heterogeneity across studies. Poultry farmers had knowledge and practice gaps on antimicrobial use. While most (65%; 95% CI: 50%-80%) used antimicrobials on poultry for therapeutic purposes, a portion used them to prevent disease (45%; 95% CI: 34%-55%) or boost growth (29%; 95% CI: 13%-46%) and productivity (20%; 95% CI: 6%-34%). 60% (95% CI: 50%-69%) of farmers approached veterinarians for antimicrobial advice, although many consulted drug sellers and fellow farmers. Insufficient antimicrobial residue knowledge (45%; 95% CI: 29%-62%), as well as inadequate awareness and faulty practice on withdrawal periods, were identified. Only 43% (95% CI: 34%-53%) were knowledgeable about AMR. Around half of farmers understood AMR's impacts on poultry, human health, and the environment. Meta-regression demonstrated that the source of heterogeneity for therapeutic antimicrobial use was the type of poultry farmers sampled and their educational qualifications; geographical region was significantly associated with antimicrobial usage based on farmers' experience; and the country's economic state was correlated with farmers' understanding of antimicrobial residue. This study recommends implementing legislation for judicious antimicrobial use, and farmer awareness campaigns to reinforce knowledge about prudent AMU and AMR.

Avian influenza viruses (AIV) increase commercial and backyard poultry mortality and morbidity, reduces egg production, and elevates public health risk. Household ducks propagate and transmit HPAI and LPAI viruses between domesticated and wild birds in Southeast Asian countries, including Bangladesh. This study was conducted to identify epidemiological factors associated with AIV infection among household ducks at Chattogram, Bangladesh. We randomly selected and collected blood and oropharyngeal swab samples from 281 households ducks. We evaluated the serum for AIV antibody using cELISA and tested for H5 and H9 subtypes using the HI test. We tested the swabs with real-time reverse transcriptase PCR (rRT-PCR) for M gene, and H5, H9 subtypes. In the duck populations, the household level AIV sero-prevalence was 57.7% (95% CI: 51.6-63.3) and RNA prevalence was 2.4% (95% CI: 1.0-5.0). H5 and H9 subtype sero-prevalence was 31.5% (95% CI: 22.2-42.0) and 23.9% (95% CI: 15.6-33.9). H5 and H9 subtype RNA prevalence were 0% (95% CI: 0.0-1.3) and 2.4% (95% CI: 1.0-5.0). We determined household-level OR (Odds Ratios) for the "combined (mixed materials-mud and concrete or metallic)" category was 2.2 (95% CI: 1.1-4.2) compared with "wooden/bamboo" category (p = 0.02); 2.8 (95% CI: 1.2-6.6) in households with duck plague vaccine coverage compared with no coverage (p = 0.01); and 2.4 (95% CI: 0.6-9.7) in households that threw dead birds in bushes and the roadside compared with households that buried or threw dead birds in garbage pits (p = 0.21). M gene phylogenetic analysis compared M gene sequences to previously reported Bangladeshi H9N2 isolates. The evidence presented here shows AIV circulation in the Chattogram, Bangladesh study areas. AIV reduction can be achieved through farmer education of proper farm management practices.

The Coronavirus Disease 2019 (COVID-19) spread rapidly from China to most other countries around the world in early 2020 killing millions of people. To prevent virus spread, world governments implemented a variety of response measures. This paper's objectives were to discuss the country's adopted measures to combat the virus through June 2020, identify gaps in the measures' effectiveness, and offer possible mitigations to those gaps. The measures taken included screening device deployment across international air and land ports, flight suspensions and closures from COVID-19 affected countries, and declaration and extension of a national public holiday (equivalent to lockdowns in other countries). Identified gaps were test kit, PPE, ICU beds, and ventilator shortages, limited public awareness, and insufficient coordination and collaboration among national and international partners. Proper and timely risk mapping, preparedness, communication, coordination, and collaboration among governments and organizations, and public awareness and engagement would have provided sufficient COVID-19 mitigation in Bangladesh.

OBJECTIVE: In developing countries, such as Bangladesh, the live bird market (LBM) is a vital location for the trading of live poultry. The study was carried out in nine LBMs located around Bangladesh to ascertain the present regulations and procedures governing their operation. Additionally, the responsibilities and levels of engagement of the stakeholders were determined. MATERIALS AND METHODS: The data were gathered through the use of a semi-structured interview guide. Thematic analysis was used to code the interview transcripts iteratively. RESULTS: The findings indicated that the government was directly and indirectly involved in the leasing process of the markets. A market in this country is divided into numerous sectors, including LBM, fish market, vegetable market, and grocery stores. A market's hygienic condition is highly dependent on market authority's decisions. In some markets, market officials conducted routine sanitary inspections. Veterinarians played a little role in the inspection procedure. CONCLUSION: There is no adequate, functional monitoring system to ensure that LBMs adhere to cleanliness and adequate and functional biosecurity. Biosecurity enhancements, effective cleaning programs, and regular monitoring by relevant authorities are critical for LBMs in Bangladesh.
RESUMEN
OBJECTIVE: A clinico-epidemiological study was conducted at two veterinary hospitals in Dhaka to evaluate the prevalence of parvoviral enteritis (PVE) in dogs and feline panleukopenia (FPL) in cats, to detect factors associated with them, and to identify their common clinical signs. MATERIALS AND METHODS: Clinico-epidemiological data were collected for a total of 88 dogs and 129 cats which were presented to the hospitals, entered into MS excel 2010, and then transferred to STATA-14 software for conducting descriptive and univariable statistical analyses (Fisher's exact test). The maps showing the spatial distribution of PVE and FPL were produced by using QGIS software version 2.18.13. RESULTS: PVE in dogs and FPL in cats had the highest prevalence compared to other diseases (34.1%; 95% confidence interval: 24.3-44.9; N = 88 and 20.2%; 95% confidence interval: 13.6-28.1; N = 129, respectively). Young age (43.8%), poor body condition (58.4%), and exotic breeds (44.2%) were significantly associated with the occurrence of PVE (p ≤ 0.05). Poor body condition (27.8%) and non-vaccination status (26.7%) were associated with FPL (p ≤ 0.05). Both PVE and FPL showed clinical signs of being off-feed, frequent vomiting, weakness, and moderate dehydration. CONCLUSION: The high prevalence of PVE and FPL indicates that they are common in dogs and cats in Dhaka, Bangladesh. The factors related to PVE are young age, exotic breed, and poor body condition score (BCS), and FPL are poor BCS and non-vaccination. Specific measures such as care during younger age, good nutrition, and routine vaccination are needed to prevent and control PVE and FPL in Dhaka's dog and cat population.
