Mycoplasma gallisepticum (MG) is the most important pathogenic Mycoplasma spp. causing avian mycoplasmosis and brought about huge economic losses to poultry industry in Bangladesh. The present study was undertaken to know the seroprevalence of MG in layer birds in three different geographical areas of southern Barishal division, Bangladesh. Total 310 sera samples were collected from wing vein of 30 farms for this study. Sera samples were tested with Rapid Serum Agglutination (RSA) for MG using commercial Antigen Kit (manufactured by Lillidale Diagnostic) to detect the presence of antibodies against MG. The overall seroprevalence of MG by RSA was 36.13%. Seroprevalence of MG infection was dominant in winter season (45.54%) and significantly highest occurrence was recorded in age groups from 20-40 weeks of layer chickens (51.79%). Serological investigation in three different upazila of Barishal division showed the highest infection rate (45.26%) in medium scale flocks (1000-3000) in comparison to (21.43%) small (<1000) flocks. The seroprevalence of MG was highest in Swarupkathi (44.38%) than in Barishal Sadar (26%) and Banaripara upazila (28%). Biosecurity and managemental failure is the overall risk factor in all types of farm due to lack of proper knowledge among farmer. This study reveals the current scenario of mycoplasmosis in layer birds of three different areas of Barishal division. Asian J. Med. Biol. Res. 2021, 7 (3), 292-297

Mycoplasma gallisepticum (MG) infection is very common in birds that cause respiratory infections in chickens, turkeys, and other avian species. It has brought about a considerable amount of financial losses to the poultry sector in Bangladesh. We conducted a study on the Seroprevalence of MG infection in two different geographical areas of Bangladesh under Rajshahi district, namely Paba and Bagmaraupazila. 800 sera samples were collected and tested with Rapid Serum Plate Agglutination Test (RSA) to identify the MG antibodies using commercial Mycoplasma gallisepticum antigen. The gross Seroprevalence of MG infection was 59.25% in the study area. The maximum rate (68.80%) of infection was found in the winter season, followed by the summer season (49.36%). The result further revealed that the condition was higher (69.01%) in larger-sized flocks than in small (53.63%). We noticed that younger birds having 10-20 weeks of age are more prone to be affected with avian mycoplamosis with an infection rate of 72% compared to their adult counterpart of 71+ weeks with 52% morbidity. Our study revealed that Mycoplasma gallisepticum infection is prevalent in Paba and Bagmaraupazila in Rajshahi. The farms should take strict bio-security measures to mitigate this infection in the mentioned areas. Proper medications for the affected birds and timely prophylactic measures for the healthy ones could be practical and preventive strategies against avian mycoplasmosis. Amid limitations, we conducted our experiments, and thus further research is warranted to substantially assess and validates our observations.

A cross-sectional study was carried out on 96 commercial layer farms of six upazilas of Khulna district to know the seroprevalence of Mycoplasma gallisepticum (MG) infection during the period from August 2009 to July 2010. A total of 1268 sera samples were collected from randomly selected layer birds of different age groups and tested by serum plate agglutination (SPA) test by using commercial MG antigen (Nobilis® MG, Intervet International) to detect the presence of antibodies against MG. The overall prevalence of MG infection was recorded as 67.4%. Age-wise analysis revealed that there was significant relationship (p<0.001) between MG infection and age of birds. The highest prevalence of MG infection was 71.2% in 21-56 weeks age group followed by 66.8% in 8-20 weeks age group. There was significant (p<0.001) variation in the seroprevalence in terms of areas of study (upazilas). Significant (p<0.001) effect of seasons in the seroprevalence of MG infection in layer birds was observed in the present study. The prevalence of MG infection was the highest (75.6%) in winter season followed by summer (66.3%) and rainy (60.8%) seasons. The seroprevalence of MG infection was higher in most of the large flocks and lower in small flocks with some exceptions. It is evident from the present study that above 50% layer birds are infected with MG organism. Therefore, it may be suggested that the layer farms should be routinely checked to monitor MG infection and the reactor birds should be culled since MG organism has the potential to transmit vertically.DOI = http://dx.doi.org/10.3329/bjvm.v8i2.9620Bangl.

Rotaviruses are considered as a major cause in the etiology of diarrhea in young calves worldwide and it causes calf morbidity, mortality and substantial economic losses in the dairy industry. This study reports the determination of the disease burden and first evaluation of associated risk factors of rotavirus infection in calves in Bangladesh. A cross sectional survey was carried out for the approximation of prevalence and associated risk factors of rotavirus infection in neonatal calves in South-eastern part of Bangladesh. From July 2015 to May 2016 a total of 411 calves under the age of 6 weeks from 210 dairy farms were selected using probability sampling scheme. Rotavirus infection was diagnosed from calf fecal samples using a commercial ELISA kit. Different farm and calf level factors were tested by mixed effect multivariable logistic regression models to differentiate factors significantly contributing to the high burden of rotavirus infection in calves in the study area. Overall prevalence of rotavirus in calf feces, irrespective of diarrheic and non-diarrheic, was estimated as 5.11%. Among the hypothesized risk factors, samples from winter season showed higher odds of having the infection compared to summer (OR=6.04). Likewise, higher odds ratios were observed in: >3 weeks of age group compared to ≤ 3 weeks (OR=2.87), taking of first colostrums after 30 minutes to 2 hours of birth in contrast to within 30 minutes (OR=13.92), and finally, calves from 3rd to 4th parity compared to 1st to 2nd parity (OR=6.79). Enteric diseases are a vital health problem in calves that interrupts production benefits with reduced weight gain and increased mortality rates and moreover it has potential to spread. Therefore, it is imperative to determine the disease burden and responsible risk factors to execute effective preventive measures among the population at higher risk. Asian J. Med. Biol. Res.

A serological investigation of Mycoplasma gallisepticum (MG) infection in chicken was conducted in the greater Rajshahi district of Bangladesh on 115 flocks during the period from July 2006 to June 2007. A total of 575 sera samples were collected and tested by serum plate agglutination (SPA) test using Mycoplasma gallisepticum antigen (Nobilis MG, Intervet International B.V. Boxmeer-Holland) to determine specific antibodies in different flocks. The overall seroprevalence of MG infection in different flocks was recorded as 55.13%. Seroprevalence of MG infection was found significantly (p < 0.05) higher during winter season (61.48%) than in summer (47.74%). Again this was recorded in different age groups, with significantly (p < 0.01) higher occurrence in young (72.72%) compared to adult (44.00%). On the other hand, the seroprevalence of MG infection was found little (p>0.05) higher in large flocks (62.86%) in comparison to small flocks (52.00%). It has been found that MG infection is still an important disease problem in chickens in Bangladesh.

Avian haematozoans are important pathogens of birds causing asymptomatic to fatal infections. The present study was undertaken to investigate the prevalence and associated risk factors of malaria parasite infections in domestic chickens and ducks in three localities namely Mymensingh, Tangail and Netrokona districts in Bangladesh. In total, 474 blood smears (266 chickens and 208 ducks) were screened for haemoprotozoan infection during the period from March, 2016 to February, 2017. Blood samples were collected from wing vein by needle puncture. The parasites were identified from Giemsa stained thin blood smears based on morphological features using standard keys. Malaria protozoa was found in 60 birds (12.7%), of which 35 were chickens (13.2%) and 25 were ducks (12.0%). Two species of blood protozoa were identified namely Leucocytozoon spp. (10.5%) and Plasmodium spp. (2.1%). The prevalence of haemoprotozoa was found high among the adults (13.9%) while it was 11.2% among young birds. Female (15.2%) was 1.46 times more susceptible than male (10.9%).The prevalence rate was highest in Netrokona (18.9%) followed by Tangail (12.2%) and Mymensingh (8.7%). In this study, the prevalence rate was highest in rainy season (18.3%), moderate in summer (10%) and less in winter season (9.3%). Present study revealed that these haemorpotozoa are capable of infecting indigenous domestic chicken and duck. Further studies should focus on characterization of the malaria parasites of indigenous chickens and ducks in Bangladesh.J. Bangladesh Agril. Univ. 15(2): 260-265, December 2017

Background: Brucellosis is an important zoonotic disease, which mostly affects cattle causing abortion and infertility and thereby huge economical loss. Hence, it is highly essential to assess the status of the disease through proper diagnostic methods and accordingly prevention strategies may be taken for control and eradication. Methods: A cross-sectional study was carried out in plain zone of Chhattisgarh to record the prevalence of bovine brucellosis and to analyse its associated risk factors during April’ 2018-January’ 2019. A total of 920 bovine sera samples were collected from non-vaccinated cross bred and non-descriptive cattle through multistage sampling. All the sera samples were screened with RBPT and indirect ELISA for detection of anti-Brucella antibody. Result: The prevalence of brucellosis in cattle was found to be 21.3% (196/920) by i-ELISA and 14.24% (131/920) by RBPT. The risk association of several factors with the prevalence of brucellosis was figured through binary logistic regression analysis, where the risk of prevalence was higher among female cattle, in the Balod district and during winter season. The study indicated that sex, season and district has significant (p≤0.05) risk associated to the prevailing anti-Brucella antibody, which will further help in designing strategic prevention and control program of the disease.

AbstractChicken astroviruses (CAstV) are enteric viruses of poultry causing gastroenteritis, malabsorption, gout and white chick disease commonly known as runting-stunting syndrome (RSS). It can affect the wide range of poultry birds, especially chicken, turkey and duck worldwide. To our best knowledge there is no published report on presence of antibodies against CAstV in Bangladesh. Therefore, the study aimed to detect the presence of CAstV antibodies in broilers and sonali chickens (a cross-bread) in Bangladesh through a cross-sectional survey. A total of 454 blood samples from 66 flocks of broiler (n=343) and sonali chickens (n=111) of different ages were obtained during 2017 from four districts. The birds were healthy but were not vaccinated against CAstV. The samples were tested for specific antibodies against CAstV Group B by using commercially available ELISA kit. Overall, 16.74% (76/454) samples and 34.84% (23/66) flocks were positive for CAstV antibodies. The seroprevalence of CAstV was significantly (p=0.001) higher in sonali chickens (36.96%) than broiler (10.20%), while it was significantly higher (p=0.001) in birds of Bogura district (36.94%) than the other three districts. Regarding the age groups, seroprevalence was insignificantly (p=0.192) higher in sonali chicken before laying age (45%) than during laying age (27.45%). Regarding the seasons, CAstV infection was prevalent significantly (p=0.001) higher in winter season. Thus, the present study indicated the presence of CAstV in poultry in Bangladesh, so further studies are required to find out the magnitude of the problem in the country.

Abstract. Flooding is assessed as the most important natural hazard in Europe, causing thousands of deaths, affecting millions of people and accounting for large economic losses in the past decade. Little is known about the damage processes associated with extreme rainfall in cities, due to a lack of accurate, comparable and consistent damage data. The objective of this study is to investigate the impacts of extreme rainfall on residential buildings and how affected households coped with these impacts in terms of precautionary and emergency actions. Analyses are based on a unique dataset of damage characteristics and a wide range of potential damage explaining variables at the household level, collected through computer-aided telephone interviews (CATI) and an online survey. Exploratory data analyses based on a total of 859 completed questionnaires in the cities of Münster (Germany) and Amsterdam (the Netherlands) revealed that the uptake of emergency measures is related to characteristics of the hazardous event. In case of high water levels, more efforts are made to reduce damage, while emergency response that aims to prevent damage is less likely to be effective. The difference in magnitude of the events in Münster and Amsterdam in terms of rainfall intensity and water depth, is probably also the most important cause for the differences between the cities in terms of the suffered financial losses. Factors that significantly contributed to damage in at least one of the case studies are water contamination, the presence of a basement in the building and people's awareness of the upcoming event. Moreover, this study confirms conclusions by previous studies that people's experience with damaging events positively correlates with precautionary behaviour. For improving future damage data acquisition, we recommend to include cell-phones in a CATI survey to avoid biased sampling towards certain age groups.

Background: Contagious caprine pleuropneumonia (CCPP), caused by Mycoplasma capricolum subsp. Capripneumoniae (Mccp), is one of the most important goat diseases causing high morbidity and mortality, these results in heavy economic losses to countries like Somalia, which is a country affected the civil war of the 1990s. Objective: Generally, the disease presence has been reported in the country. However, there is no quantitative data on the prevalence and distribution of the disease has been scientifically reported in the country. Methods: A cross-sectional study was conducted from September 2019 to June 2020 in three villages of Afgoye district of Somalia to assess the seroprevalence and identify the associated risk factors for the occurrence of the CCPP. The risk factors considered included sex, age, and locations. Results: A total of 100 blood samples were collected and evaluated by Capri-Latex Agglutination Test (Capri-LAT). A total of 49/100 (49%, CI 95%: (38.86%-59.2%) goats were seropositive for anti-CCPP antibody. The epidemiological risk factors considered, sex, age and locations, were not significantly associated with the CCPP sero prevalence (p>0.05). However, the sero positivity was slightly higher in female (51%, 95% CI: 39.8-62.6), >3 years old goats (86.3%, 95% CI: 48.9-87.4) and Markazka village (56%, 95% CI: 41.3-70.0) compared to male (40%, 95% CI: 19.1-63.9), 1-3 years old (57.5%, 95% CI: 40.9- 73.0), and Shareeco (43.8%, 95% CI: 19.8-70.1) and Siinka (41.2%, 95% CI: 24.7-59.3) villages, respectively. Conclusion: The present study indicates the prevalence of CCPP in the studies areas and this requires practicable measures to be put in place towards the control of the disease.
