Brucellosis, a bacterial zoonotic disease, has been reported in ruminants but still no report in pigs in Bangladesh. The aim of this study was to describe seroprevalence of brucellosis in swine in Bangladesh. Blood from a total of 105 pigs was collected from selected areas of Bangladesh. All samples were screened using Rose Bengal Test (RBT) and further confirmed by using Slow Agglutination Test (SAT). A structured questionnaire was used to collect the epidemiological data related to the animals and husbandry practices. Out of the 105 sera analyzed, 7 (6.7%) and 5 (4.8%) were found to be positive by RBT and SAT respectively. It was observed that, insignificantly higher prevalence of brucellosis based on SAT was found in female (5.6%) than male (2.9%), in aged animal (8.1%) than young (0.0%) and in pregnant animal (12.5%) than non pregnant animal (2.1%) (p>0.05). Prevalence of brucellosis was 42.9% in aborted pigs and 1.6% in non aborted pigs. The association between abortion status and prevalence of brucellosis was statistically highly significant (p<0.01). This report of prevalence of brucellosis in pigs is very important with regards to the human health and other livestock and might help Government and NGOs to design preventive measurement and establish livestock health policy.DOI: http://dx.doi.org/10.3329/bjvm.v10i1-2.15649

The Status

Brucellosis is a zoonotic disease which affects humans, farm animals and wildlife as well. In Pakistan, the status of human and farm animal brucellosis is documented but the information about brucellosis in wildlife is lacking. To access the seroprevalence of Brucella antibodies in avian (turkeys, peafowl, guineafowl, mallard ducks and Indian blue rock pigeon) and selected wild species (reptiles and amphibians), a total of 117 serum samples (reptile = 34, amphibian = 04, avian n = 79) were collected from Karachi and Pattoki regions of Pakistan. Serum samples were screened for Brucella antibodies using Rose Bengal plate test (RBPT) and11.1% serum samples were found positive. Overall, 2.5% birds, 29.4% reptiles and 25% amphibians were seropositive for Brucella antibodies. This is first report of detection of Brucella antibodies in reptiles and amphibians in Pakistan.

Brucellosis is an important bacterial zoonotic disease causing significant economic loss in dairy industries worldwide including Bangladesh. But limited studies are devoted to determine the prevalence of brucellosis in goat in all districts of Bangladesh. Therefore, a cross-sectional study was undertaken to determine the seroprevalence of brucellosis in Black Bengal goats in Nilphamari Sadar and Kishoreganj upazillas of Nilphamari district of Bangladesh using Rose Bengal Test (RBT) as screening test and I-ELISA as confirmatory test. A total of 154 sera samples from Black Bengal goats were collected from Nilphamari district. Epidemiological data on the selected Black Bengal goats were collected using a structured questionnaire. The overall seroprevalence of brucellosis was found to be 2.59% in Black Bengal goats. A significantly (p<0.01) higher prevalence of brucellosis was found in Black Bengal goats with the history of previous abortion (33.33%). An insignificant (p>0.05) but higher prevalence of brucellosis was found in adult Black Bengal goats (>24 months) than young. The prevalence was relatively higher in cross-bred than pure Black Bengal goats, in female than male and in pregnant than non-pregnant Black Bengal goats. The result of the study will provide baseline data for control of brucellosis in goat in Bangladesh.DOI: http://dx.doi.org/10.3329/bjvm.v10i1-2.15646

The introduction of non-native species and deforestation are both important drivers of environmental change that can also facilitate the geographic spread of zoonotic pathogens and increase disease risk in humans. With ongoing trends in globalization and land-use conversions, introduced species and deforestation are ever more likely to pose threats to human health. Here, we used rat lungworm disease, an emerging zoonotic disease caused by Angiostrongylus cantonensis and maintained by invasive rats and snails, to explore how these two forms of environmental change can impact zoonotic disease risk. We used logistic regressions to examine the role of global trade in the introduction of A. cantonensis at a country level and used model estimates to predict the probability of introduction as a function of trade. We then used hurdle-based regression models to examine the association between deforestation and rat lungworm disease in two regions where A. cantonensis is already established: Hawaii and Thailand. At the global scale, we found the trade of horticultural products to be an important driver in the spread of A. cantonensis and that the majority of countries at high risk of future A. cantonensis introduction are islands. At country scales, we found deforestation to increase the per-capita risk of A. cantonensis exposure in Hawaii and Thailand. Our study provides a preliminary view of the associations between species introductions, deforestation, and risk of A. cantonensis exposure in people. Better understanding how these two widespread and overlapping forms of environmental change affect human health can inform international biosecurity protocols, invasive species management, and land-use policies.

Background: Leptospirosis is a zoonotic disease of worldwide significance in human beings and many animals. This zoonotic disease causes infection in dogs and other pet animals and these animals can influence human’s health. Given the unknown prevalence of leptospirosis in dogs in our area, this study was performed to investigate the sero-epidemiology of leptospirosis and evaluate the seroprevalence of Leptospira serovars in both household and stray dogs by microscopic agglutination test (MAT). Methods: Serum samples of 90 dogs in two household and stray groups (45 dogs for each group) were collected. Specimens were examined by MAT (in accordance with the procedure recommended by WHO) against antigens of serovars Canicola, Grippotyphosa, Icterohaemorrhagiae, Pomona, Hardjo, Autumnalis, and Ballum. Results: In total, 6.7% of (n=6) dogs (1 stray and 5 household dogs) had a serum titer of 1:100 or more against Leptospira serovars. Dominant serovars were Canicola (8.9%), Grippotyphosa (2.2%), and Pomona (2.2%), respectively. The antibody titer against more than one serovar was observed only in one dog. The sero-prevalence was 11.1% in household dogs and 2.2% in stray dogs. Since 4 pet dogs had been vaccinated recently, it seems that the actual percentage of infection in household dogs must be just 2.2% and actual infection in dogs including stray dogs is approximately 4.4% in Tabriz. Conclusion: Fortunately, the rate of infection in Tabriz is low and this can be due to special geographical and climatic conditions, regular and annual vaccination of household dogs against this disease, and lack of suitable conditions for the growth and survival of such micro-organisms in the environment

Worldwide, tobacco is one of the leading causes of disability and death. Over a million of pounds of toxic chemicals are released by tobacco products. This study aims to explore the effects of tobacco toxicants on human health and environmental pollution. Four districts (Dhaka, Kushtia, Chattogram and Rangpur) were selected where most of the tobacco product grown. Total 468 respondents were interviewed face-to-face using structured questionnaire to assess the knowledge about toxicant content in tobacco and health and environmental hazards of tobacco use. Survey results revealed that about 44.4% respondents used smoking tobacco products and 38.5% used smokeless tobacco, while only 17.1% used both. About two third (74.3%) of smoking tobacco users started smoking when they were between 15 to 24 years old and majority (61.6%) of smokeless tobacco users started tobacco when they were between 30 to 35 years above. Tobacco product has large impacts on health of young smokers. Smokers are suffering from various acute and chronic diseases. Among the respondents, 38% indicated that they were suffering from hypertension. The second most affected disease was COPD/Asthma (31.6%), while cancer was the least suffering disease (0.4%). Majority of the respondents were not aware about the presence of toxicants (i.e. nicotine, tar and metals) in tobacco products. However, 85.1% tobacco users had an idea about environmental pollution. There is a lack of knowledge among the survey respondents about toxicants in tobacco products that are linked to health hazards and environmental pollution. These results are important in strengthening existing policy considering adverse health effects of toxicants examined. Progressive Agriculture 31 (3): 130-143, 2020

ABSTRACT The results of seven serologic tests for diagnosis of human brucellosis were evaluated. The titrated Rose Bengal test, microagglutination test, microtiter-adapted Coombs test, and immunocapture-agglutination test (Brucellacapt) were positive for all sera from patients with acute brucellosis. The immunoglobulin G (IgG), IgM, and IgA commercial enzyme immunoassays (ELISAs) failed to show specific antibodies in 3 patients, 10 patients, and 1 patient, respectively. The sensitivity of ELISA is not higher than that of conventional tests.
