A random survey was conducted to study the epidemiology of brucellosis in Punjab (India), using the 'Survey Toolbox' sampling software. A two-stage sampling procedure was adopted: in the first stage, villages were selected, and in the second the selection of animals was made. In all, 52 villages were selected randomly from a sampling frame of all the villages of Punjab. The total number of animals in these villages was 18,644, out of which 973 animals (approximately 5%) belonging to various owners were randomly selected. Serum samples collected from the animals were screened for Brucella antibodies by an avidinbiotin enzyme-linked immunosorbent assay, which showed the apparent overall prevalence of brucellosis to be 12.09% (true prevalence, 11.23%). The prevalence varied from a low of 0% to a high of 24.3% in various districts. Higher variance (0.08) was noted within villages than between different villages (0.03). The prevalence rates among buffaloes and cattle were 13.4% and 9.9%, respectively. The seroprevalence of brucellosis was found to be significantly higher (chi square = 24.50, p < 0.001) in animals with a history of abortion (33.87%) than in those without such a history (11.63%).

The indiscriminate usage of antimicrobials in the animal health sector contributes immensely to antimicrobial resistance (AMR). The present study aims to assess the antimicrobial usage pattern and risk factors for AMR in animal husbandry sector of India. A cross-sectional survey about Knowledge, Attitude, and Practices (KAP) among veterinarians was carried out using a questionnaire comprising of 52 parameters associated with antibiotic use and the emergence of AMR in dairy herds. Respondents’ KAP scores were estimated to rank their level of knowledge, attitude, and practice. Furthermore, risk factors associated with treatment failure were analyzed by univariable and multivariable analyses. Out of a total of 466 respondents, the majority had average knowledge (69.5%), neutral attitude (93.2%), and moderate practice (51.3%) scores toward judicious antibiotic usage. Veterinarians reported mastitis (88.0%), reproductive disorders (76.6%), and hemoprotozoan infections (49.6%) as the top three disease conditions that require antibiotic usage. Most of the veterinarians (90.6%) resorted to their “own experience” as the main criteria for antibiotic choice. The use of the highest priority critically important antimicrobials (HPCIA) listed by the World Health Organization (WHO) in animals, particularly quinolones (76.8%) and third-generation cephalosporins (47.8%), has been reported. On multivariable regression analysis of the risk factors, the lack of cooperation of the dairy farmers in the completion of a prescribed antibiotic course by the veterinarian and the demand for antibiotic use even in conditions not requiring antibiotic use were found to be significantly associated with the outcome variable “treatment failure” having respective odds of 1.8 (95%CI: 1.1–3.0) and 3.6 (95%CI: 2.3–5.8) (p < 0.05). The average KAP score of veterinarians, poor farm management practices, lack of awareness among farmers on prudent antibiotic use, and lack of antibiotic stewardship are the significant factors that need attention to combat the rising AMR in veterinary sector in India.

Aim: The present study was conducted to assess the awareness, knowledge, and risks of zoonotic diseases among livestock farmers in Punjab.Materials and Methods: 250 livestock farmers were selected randomly and interviewed with a pretested questionnaire, which contained both open and close ended questions on different aspects of zoonotic diseases, i.e., awareness, knowledge, risks, etc. Knowledge scorecard was developed, and each correct answer was awarded one mark, and each incorrect answer was given zero mark. Respondents were categorized into low (mean − ½ standard deviation [SD]), moderate (mean ± ½ SD), and high knowledge (Mean + ½ SD) category based on the mean and SD. The information about independent variables viz., age, education, and herd size were collected with the help of structured schedule and scales. The data were analyzed by ANOVA, and results were prepared to assess awareness, knowledge, and risks of zoonotic diseases and its relation with independent variables.Results: Majority of the respondents had age up to 40 years (70%), had their qualification from primary to higher secondary level (77.6%), and had their herd size up to 10 animals (79.6%). About 51.2% and 54.0% respondents had the history of abortion and retained placenta, respectively, at their farms. The respondents not only disposed off the infected placenta (35.6%), aborted fetus (39.6%), or feces (56.4%) from a diarrheic animal but also gave intrauterine medication (23.2%) bare-handedly. About 3.6-69.6% respondents consumed uncooked or unpasteurized animal products. About 84.8%, 46.0%, 32.8%, 4.61%, and 92.4% of livestock farmers were aware of zoonotic nature of rabies, brucellosis, tuberculosis, anthrax, and bird flu, respectively. The 55.6%, 67.2%, 52.0%, 64.0%, and 51.2% respondents were aware of the transmission of zoonotic diseases to human being through contaminated milk, meat, air, feed, or through contact with infected animals, respectively. The transmission of rabies through dog bite (98.4%), need of post-exposure vaccination (96.8%), and annual vaccination of dogs (78%) were well-known facts but only 47.2% livestock owners were aware of the occurrence of abortion due to brucellosis and availability of prophylactic vaccine (67.6%) against it as a preventive measure. About 69.2% respondents belonged to low to medium knowledge level categories, whereas 30.8% respondents had high knowledge (p<0.05) regarding different aspects of zoonotic diseases. Age, education, and herd size had no significant effect on the knowledge level and awareness of farmers toward zoonotic diseases. Conclusion:Therefore, from the present study, it may be concluded that there is a need to create awareness and improve knowledge of livestock farmers toward zoonotic diseases for its effective containment in Punjab.

Withanolides are a group of naturally occurring oxygenated ergostane type steroids, having lactone in side chain and 2-en-1-one system in the ring. Withanolides are present in medicinal plants of Solanaceae family. Formulations based on these medicinal plants are widely used in Ayurveda and traditional Chinese medicine. Withanolides have shown a wide range of pharmacological activities including hypno¬sedative, immunomodulatory, anti-inflammatory, antiarthritic, angiogenesis inhibitor, anticholinesterase, antioxidant, antibacterial and above all, antitumour. Withaferin A is the best studied withanolide as far as pharmacological investigations are concerned. The present review summarises the investigative work carried out on bioactive withanolides.
