Article Synopsis
  • Stress is an external factor that exert pressure on biological systems, and heat stress occurs when animals can't regulate their body temperature due to excessive heat, leading to serious physiological issues.
  • Common symptoms of heat stress include heat exhaustion, heat stroke, and cramps, which adversely affect the physiological functions, particularly reproductive capabilities, in mammalian species like ruminants.
  • To combat heat stress and its negative impacts on reproduction, strategies such as modifying the microenvironment, nutritional adjustments, breeding heat-tolerant breeds, and using hormonal treatments are being developed to help farmers improve fertility rates in livestock.

India is ranked as the 2nd largest egg producer in the world. Despite the prevalence of backyard poultry (free range), a majority of the commercial egg-laying hens in the country are still housed in battery cages. There is a global shift toward cage-free eggs, due to regulations and increased demand from conscious consumers and food corporations.

  • The study investigated the resistance of Rhipicephalus microplus ticks in Maharashtra, India, to synthetic pyrethroids, cypermethrin and deltamethrin, revealing all isolates tested were resistant to deltamethrin, with varying resistance levels across different regions.
  • It found significant increases in the activity of α- and β-esterase enzymes in treated larvae, suggesting a biochemical response to these insecticides, with specific isolates showing notably high enzyme activity after exposure.
  • The findings indicate that both deltamethrin and cypermethrin are ineffective for tick control in the region, prompting recommendations for stricter regulation of these compounds and the development of alternative tick control strategies.

Scrub typhus is a vector-borne disease caused by Orientia tsutsugamushi, propagated into humans by the bite of infected mite belonging to genus Leptotrombodium. The present study was conducted in the Nagpur region of central India aiming towards a survey of cohabiting rodents and their potential vectors for the presence of Orientia tsutsugamushi by PCR method. The study also emphasizes serological diagnosis of the disease by employing indirect IgM ELISA and IFA amongst the human cases of pyrexia of unknown origin.

Article Synopsis
  • Tick-borne diseases are a major issue for cattle in tropical and subtropical India, causing significant economic losses for small farmers, particularly in Tamil Nadu.
  • A study identified the most common tick species infesting cattle, with Rhipicephalus microplus being the most prevalent, particularly affecting cross-bred cattle more than native breeds.
  • The research utilized PCR to assess Theileria annulata infection rates in ticks, revealing that H. anatolicum is the main vector for the disease, highlighting the effectiveness of PCR in detecting low infection levels in ticks.

Peste des petits ruminants virus (PPRV) is known to induce transient immunosuppression in infected small ruminants by modulating several cellular pathways involved in the antiviral immune response. Our study shows that the PPRV-coded non-structural proteins C and V can interact with the cellular NF-κB p65 subunit. The PPRV-C protein interacts with the transactivation domain (TAD) while PPRV-V interacts with the Rel homology domain (RHD) of the NF-κB p65 subunit.

Autophagy is an essential and highly conserved catabolic process in cells, which is important in the battle against intracellular pathogens. Viruses have evolved several ways to alter the host defense mechanisms. PPRV infection is known to modulate the components of a host cell's defense system, resulting in enhanced autophagy.

Orexin is a ligand for orexin receptors OX1R and OX2R; it is a neuropeptide with pleiotropic functions, including regulation of reproduction. The current study was carried out to investigate the mRNA expression of the prepro-orexin gene (PPO) and orexin receptors (OX1R and OX2R) in ovarian follicles during different stages of their development in the ovary of water buffalo (Bubalus bubalis) and to determine the role of orexin on oestradiol production. Ovarian follicles were classified into four groups based on size and oestradiol (E ) level in the follicular fluid (FF) as follows: (i) small or F1, (ii) medium or F2, (iii) large or F3, and (iv) dominant/pre-ovulatory follicle or F4.
