The livestock sector has been suffering significant financial losses for many years as a result of the disease. The present research work was focused on the isolation, documentation and serotyping of the Foot and Mouth Disease (FMD) virus from different locations. Reverse Transcription Polymerase Chain Reaction (RT-PCR) was used to detect the FMD virus (FMDV) serotype-O that is currently circulating in the BHK-21 cell line. All the tested samples were positive for FMDV and specific for serotype-O was 64.67-52.67% from tongue epithelium tissues and 30.67-16.67% from foot tissues respectively based on locations. In BHK-21 cell lines, the viruses caused cytopathic effects such as rounding, enlargement, intercellular bridge breakdown, and finally, death of cells, which shows the presence of the FMD virus under an inverted microscope. The BHK-21 cell culture fluid was found positive for FMDV in cell culture and also was positive based on CPE. Once more, the resulting inoculum was used to serotype the virus using RT-PCR. Based on the result of the RT-PCR method, the conclusion reached was that the serotype of the FMD virus was ‘Type O’.\u0000Asian J. Med. Biol.

A total of 2832 poultry birds (deshi chicken, sonali, duck and pigeon) were selected from 170 households. The data were collected according to prepared questionnaire. The study revealed that, most of the farmers reared their poultry in semi scavenging system (97.64%). The poultry houses were commonly made of tin and bamboo (88.82%) and some of farmers kept their poultry in houses which were at unsatisfactory level (11.2%). They used polythene, sack, ash, sand, straw, papers separately or together as bedding materials (78.82%) and 21.18% of farmers did not use any bedding materials. They usually cleaned poultry house irregularly (73.53%). The rice (84.71%) as feed supplement followed by boiled rice, paddy, broken rice, wheat and commercial as well,  was commonly given twice (62.9%) in a day. The farmers did not usually use feeder and waterer (44.12%) and use only 8.82% of vaccine. The supplementary feed to each deshi chicken, sonali, duck and pigeon per day were 32.77 g, 38.70 g, 82.04 g and 12.40 g gaining average body weight of 1.19 kg, 1.36 kg, 1.22 kg and 315.35 g respectively. The average egg production per deshi chicken, sonali, duck and pigeon per year were 37.27, 47.30, 84.66, and 19.90 containing average weight 35.01 g, 41.20 g, 52.68 g and 11.10 g successively. Furthermore, the mean hatchability was found 77.50% in deshi chicken, 79.25% in sonali, 78.95% in duck and 97.45% in pigeon along with 28.79% significant (P<0.05) mortality in deshi chicken, 30.35%  in sonali, 14.50%  in duck and 11.40% in pigeon consecutively. The prevalence of diseases were investigated as Newcastle disease, fowl cholera, duck cholera, duck plague and pigeon pox. Diseases (54.1%) are the most current constraints followed by lack of knowledge, predators for poultry rearing in backyard system.

The present study investigated the prevalence of PPR in Black Bengal goats reared in Jaintapur, Sylhet and concurrent hematology, liver and kidney function tests of PPR infected goats. Information of PPR infected goats was recorded according to age and sex by asking questions to the owner or farmers. Blood samples from 10 PPR-infected Black Bengal goats and 10 normal healthy goats were collected and analyzed using routine blood and biochemical tests. PPR positive cases were found in 60 of 125 goats examined based on clinical signs. The highest prevalence (50%) was recorded in young goats (below 12 months) followed by goats of 12-24 months of age and older goats (above 25 months). Older goats were less susceptible to PPR infection. Male goats were less susceptible to PPR infection (31.66%) compared to female goats (68.33%). PPR is more likely in goats with lower body condition score (BCS). PPR-infected goats had macrocytic hypochromic anemia, as evidenced by significantly lower TEC, Hb, and PCV levels and higher MCV and MCH levels. The total leucocyte count (TLC) was significantly (P<0.05) decreased, neutrophils numbers were significantly increased but lymphocyte numbers were decreased in PPR infected goats. ALT, AST and creatinine reflect the liver and kidney functions. PPR-infected goats had significantly higher (P<0.05) AST, ALT and creatinine values than normal healthy goats. A high level of AST and ALT in PPR-infected goats might be due to liver damage. The high creatinine level indicates functional damage to the kidney. In conclusion, Prevalence of PPR in higher in Black Bengal goats reared in Jaintapur, Sylhet and PPR virus altered the hematological parameters and liver and kidney function test of the PPR infected goats.\u0000Asian J.

A cross-sectional study was conducted among 259 under five children's (12-59 months) in Barisal city, Bangladesh, from June to December 2019 using a structured questionnaire. Data was collected by interviewing the mothers from different slum areas. Chi-squared test and multiple logistic regression models were used to explore the association. Prevalence of good hygiene practices status was 65.3% and fully immunized was 71.4%. Joint family (AOR=0.54; 95% CI: 0.31-0.95; P<0.05), monthly family income less than 10,000 BDT (AOR=0.52, 95%CI: 0.32-0.97; P<0.05) were less likely to practice good hygiene.

The present study aimed to investigate the effectiveness of the ChAdOx1 nCoV-19 vaccine in between vaccinated and unvaccinated cohorts. A retrospective multicenter cohort study comprised 1244 COVID-19 positive patients enrolled in this study from three different hospitals among patients who had been appropriately vaccinated or not between April and June 2021. Data were collected by face-to-face survey, and clinical investigations were obtained by observation. Descriptive statistics and the Cox proportional hazard model of survival analysis were performed in the study. Among the participants, 69% of vaccinated cohorts did not require hospitalization, and 97% successfully recovered from the infection. In respect of age, compared with unvaccinated cohorts, the vaccine effectiveness varied from 81% to 92%. The ChAdOx1 nCoV-19 vaccine was more effective among those aged 60-69 years old and reduced 92% hazard of death than the unvaccinated group [HR ratio - 0.081(.036-.179), P=0.0001]. The study found the ChAdOx1 nCoV-19 vaccine is highly effective for receivers.

This study is aimed to investigate the status of chromium (VI) content in broiler feeds and water, as well as the risk of chromium (VI) in broiler meat, liver, and brain. For this investigation, a total of five broiler-rearing farms were chosen, each with a different type of broiler feed. A total of fifteen broiler chickens along with the water and feed samples were collected from those broiler farms. The concentration of chromium (VI) in feed, water, broiler meat, liver, and brain samples was determined using an Atomic Absorption Spectrophotometer (AAS). Two feed samples (Farm B and Farm D) were found to be chromium (VI) polluted (3.157±0.050 mg/Kg and 3.510±0.095 mg/Kg respectively), while water samples were found to be devoid of contamination. Only meat, liver, and brain samples from several farms were found to have chromium (VI). Brain samples exhibited the highest concentration of chromium (3.550±1.281 mg/Kg) compared to the liver (2.700±1.084 mg/Kg) and muscle meat (0.857±0.076 mg/Kg) samples. The amounts of chromium (VI) in the broiler brain and liver were found to be substantially higher than FAO and WHO acceptable standards. The rate of chromium (VI) concentration in meat samples was below the allowed level. It is proposed that precautions should be taken to detect chromium in chicken feed to assess health hazards and protect humans from food that could have serious negative consequences for their health.\u0000Asian J.

In many ways, including via enhanced food security, employment, and economic growth, the agricultural sector as a whole and fisheries in particular have made significant contributions to enhancing people's health and well-being. A variety of measures may be used to determine the financial health of the fish farms. The purpose of this study was to estimate the financial viability of fish pond farming and to ascertain its advantages and disadvantages. From the Taltoli upazila in the Barguna area, sixty pond fish breeders were randomly selected. These figures allow us to calculate the gross cost of producing pond fish per hectare to be 1378806 BDT, the gross return to be 2125023 BDT, and the net return to be 746217 BDT. The findings of this study proved that pond fish farming was a profitable endeavor in the region that was being studied. The Cobb-Douglas production function was further employed in order to better comprehend the part that each variable in the production of pond fish plays. The majority of the taken into account factors were demonstrated to have a considerable impact on fish productivity. The returns on pond fish production were positively and statistically significantly impacted by four of the six parameters studied. To improve the management and cultivation of pond fish farming, certain recommendations were made.\u0000Asian J. Med. Biol.

The experiment was carried out to assess the responses of salinity on the growth, nutrient accumulation and yield of rice genotypes BRRI dhan29 (salt-sensitive) and BINA dhan-10 (salt-tolerant). The pot experiment was conveyed at the net house to evaluate the response of two rice genotypes at five levels of salt stresses (0, 25, 50, 75, 100 mM NaCl) at the vegetative stage. After harvesting of rice, electrical conductivity of soil was analyzed. Growth, yield components, grain and straw yields were evaluated. Binadhan-10 showed a higher salt tolerance in physiological parameters of rice than BRRI dhan29. A significant reduction of growth, yield components, grain and straw yields of both rice genotypes was found in response to salt stress. At different salt stress conditions nutrient uptake (NPS) and K+/Na+ ratio was significantly decreased in both rice genotypes. Yet, K+/Na+ ratio was more in salt-tolerant variety than salt-sensitive variety.\u0000Asian J. Med. Biol.
