The widespread utilization of synthetic chemicals, including weedicides, pesticides, insecticides, and fertilizers, has contaminated the environment. Therefore, it is crucial to recognize the ongoing threat of various stressors, including exposure to synthetic and natural chemicals on various target and non-target living organisms. Lufenuron is extensively utilized in controlling ectoparasites in companion animals and may offer a potential solution for addressing analogous challenges in commercial poultry farming.

Lindane is a broad-spectrum insecticide widely used on fruits, vegetables, crops, livestock and on animal premises to control the insects and pests. The extensive use of pesticides and their residues in the soil and water typically join the food chain and thus accumulate in the body tissues of human and animals causing severe health effects. The study was designed to determine the toxicity effects of sub-lethal concentrations of lindane on hemato-biochemical profile and histo-pathological changes in Rohu (Labeo rohita).

Enterotoxaemia is a severe disease caused by and render high mortality and huge economic losses in livestock. However, scanty information and only few cases are reported about the presence and patho-physiology of enterotoxaemia in camels. The bacterium induces per-acute death in animals due to rapid production of different lethal toxins.

Liver disease is a serious health concern in today's world, posing a challenge to both healthcare providers and pharmaceutical companies. Most synthetic drugs and chemicals cause liver damage accounting for approximately 10% of acute hepatitis and 50% of acute liver failure. The present study aimed to evaluate the hepato-protective activity of an extract of chicory formulation assisted by silver nanoparticles against carbon tetra chloride (CCl)-induced hepatic damage in rat's liver.

The occurrence of -induced subclinical mastitis holds significant implications for public health. This specific microorganism possesses a wide array of pathogenic factors that enable it to adhere to, colonize, invade, and infect the host. The objective of the current study was to assess the prevalence of , determine antimicrobial resistance patterns, and identify virulence genes of methicillin-resistant (MRSA) strains responsible for subclinical mastitis in bovines.

Introduction: Animal tuberculosis is an infectious, chronic, granulomatous, and debilitating disease affecting animals as well as humans. However, in recent decades, there have been many endemic geographic localities where animal tuberculosis has been identified in wildlife reservoirs, limiting the eradication program in cattle. This study aimed to identify animal tuberculosis in captive zoo animals in Pakistan.

The IL-33/ST2 axis is known to be involved in liver pathologies and IL-33 is over-expressed in mouse hepatitis models. We aimed to investigate the proposed protective effect of IL-33 in murine fulminant hepatitis induced by a Toll like receptor 3 (TLR3) viral mimetic, Poly I:C or by Concanavalin-A (ConA). The Balb/C mice were administered intravenously with ConA (15 mg/kg) or Poly I:C (30 μg/mouse) to induce acute hepatitis along with vehicle control.

Background: Liver inflammation or hepatitis is a result of pluripotent interactions of cell death molecules, cytokines, chemokines and the resident immune cells collectively called as microenvironment. The interplay of these inflammatory mediators and switching of immune responses during hepatotoxic, viral, drug-induced and immune cell-mediated hepatitis decide the fate of liver pathology. The present review aimed to describe the mechanisms of liver injury, its relevance to human liver pathology and insights for the future therapeutic interventions.

The present study aimed to investigate the deleterious effects of chlorpyrifos (CPF) in experimentally exposed broiler birds. The experiment was carried out on one day old (n = 120) broiler chicks. The CPF was reconstituted in corn oil as vehicle (1 ml/kg) to obtain a final concentration of a single dose to the birds 5, 10 and 20 mg/kg body weight (BW) for fourteen days of the experiment through the stomach tube.
