Seroprevalence of Infectious bovine rhinotracheitis (IBR) in India: A 5-year study.

Infectious bovine rhinotracheitis (IBR) is a highly contagious disease of bovines causing respiratory symptoms, abortions, and reduced milk yield, leading to huge economic losses. Reports on seroprevalence in bovines in India are available and restricted to districts/states. In the present study, a nationwide seroprevalence of IBR in bovines was conducted to provide a national IBR seroprevalence to the Chief Veterinarian who in turn can design the control strategies. A total of 15,592 cattle and buffalo serum samples from 25 states and 3 Union Territories viz., Jammu and Kashmir, Puducherry, and Andaman and Nicobar Islands were tested for IBR antibodies using Avidin­Biotin (AB) ELISA. Cumulative seropositivity was found to be 31.37%. Maharashtra and Rajasthan states, part of the west zone of the country, showed the highest and lowest seroprevalence, respectively. A total of 11,423 cattle and 4,169 buffalo serum samples were tested, which showed 33.91% and 24.39% seropositivity, respectively. India has the highest buffalo population. Presently, India no IBR vaccination programs are implemented in India. Considering the high seroprevalence, the authorities should plan control strategies for vaccinating dairy cows and buffaloes in India.

Antimicrobial, antioxidant and anti-inflammatory activities of seeds from emblica officinalis (Gaertn.).

There is a shred of evidence to suggest that Emblica officinalis Gaertn, the botanical name for amla seeds, has greater medicinal potential than amla fruit. We conducted this work to assess the anti-inflammatory, antibacterial, and antioxidant capacities of E. officinalis seed extracts. The bioactive components from the seeds were fractionated using chloroform, hexane, methanol, and diethyl ether, according to the polarity of the solvents. The total amount of phenolic and flavonoid was estimated. Both the reducing power and antioxidant capacities of the extracts were evaluated using the DPPH (1,1-diphenyl-2-picryl-hydrazyl) technique. 15-lipoxygenase (LOX) was inhibited by seed extracts at doses ranging from 5 to 25 micrograms. In silico docking was employed to assess the results. Some human pathogenic microorganisms were tested for their antibacterial activity using the agar disc diffusion method. Escherichia coli, Proteus vulgaris, and Klebsiella pneumonia were inhibited by a methanolic extract with an IC50 value of 58g, making it the most common organic solvent extract. Methanolic extracts also showed good antioxidant and antibacterial activity. Our investigation led us to discover that amla seeds have anti-inflammatory, antioxidant, and antibacterial effects.
