Background and Aim: One of the worst zoonotic illnesses, avian influenza (AI), or commonly referred to as bird flu, is caused by viruses belonging to the genus Influenza viruses, which are members of the Orthomyxoviridae family. The harmful effects of AI illness can affect both human and animal health and cause financial losses. Globally, the AI virus lacks political purpose and is not limited by geographical limits. It has been isolated from poultry, wild birds, and captive birds in Asia, North America, Europe, Australia, and South America. Their virulence is divided into highly pathogenic AI (HPAI) and low pathogenic AI (LPAI). The AI virus can also be diagnosed in a laboratory setting using molecular tests like real-time polymerase chain reaction or serological tests like the hemagglutinin inhibition test, agar gel immunodiffusion, antigen detection enzyme-linked immunosorbent assay, and other immunoassays. The type of AI virus and host species determines the clinical manifestations, severity, and fatality rates of AI. Human infection with AI viruses typically results from direct transmission from infected birds to humans. AI outbreaks in domestic and wild birds are uncommon; however, an infection can pose a significant threat to public, veterinary, and medical health. Successful vaccination reduces the probability of AI H5N1 virus infection in meat and other poultry products and prevents systemic infection in chickens. This review will provide information that can be used as a reference for recognizing the dangers of AI and for preventing and controlling the disease, considering its potential to become a serious pandemic outbreak.

Background and Aim: Bluetongue (BT) is an economically important viral disease of domestic and wild ruminants, caused by the bluetongue virus (BTV), and transmitted primarily by Culicoides midges. The virus has at least 28 known serotypes and several emerg­ing strains, with its distribution expanding beyond traditional endemic zones due to climate change and global trade. This review summarizes recent developments in the epidemiology, molecular characterization, diagnostics, vaccines, and con­trol of BT, with an emphasis on its implications within the One Health framework. A comprehensive literature search cov­ering studies from 2000 to 2025 revealed significant outbreaks in Europe (2024–2025) involving BTV-3 and BTV-12, as well as the emergence of novel serotypes in Asia and Africa. Global economic losses exceed USD 3 billion annually due to mortality, production losses, and trade restrictions. Advances in molecular diagnostics, such as reverse transcription polymerase chain reaction, whole-genome sequencing, and rapid field assays like loop-mediated isothermal amplification and clustered regularly interspaced short palindromic repeats -based platforms, have improved surveillance and serotype identification. Although vaccination remains the cornerstone of BT control, current live and inactivated vaccines are lim­ited by serotype specificity and reassortment risks, highlighting the need for new-generation virus-like particle, recombi­nant, DNA, and mRNA-based vaccines. Persistent challenges include the absence of differentiating infected from vaccinated animals -compatible polyvalent vaccines, incomplete knowledge of wildlife reservoirs, and uneven surveillance capacities worldwide. Strengthening integrated vector management, genomic monitoring, and climate-informed control strategies through a coordinated One Health approach will be vital to reduce the global burden of bluetongue.

Objective: The objective of the present study was to determine the effects of mangosteen peel and ginger rhizome on the performance and cholesterol levels of heat-stressed broiler chickens. Materials and Methods: One hundred unsexed day-old commercial broiler chicks were fed one of four experimental diets. Diet T1, the control treatment, contained neither mangosteen peel nor ginger rhizome, diets T2 and T3 contained 5% mangosteen peel and 5% ginger rhizome, respectively and diet T4 contained 2.5% of both mangosteen peel and ginger rhizome. Results: The results indicated that the consumption of diet T4 was significantly higher than that of the other three diets (p<0.05). The mean live weight of broilers fed diets T2 and T4 was significantly greater (p<0.05) than that of broilers fed the control diet. The abdominal fat ratios and cholesterol levels of broilers fed diets T3 and T4 were significantly higher (p<0.05) than that of broilers fed the control diet. Conclusion: The performance of broiler chickens can be enhanced by the addition of mangosteen peel or a combination of mangosteen peel and ginger rhizome to feed formulations.

Wound healing is a physiological process that occurs progressively through overlapping phases. Tissue oxygenation is an important part of the complex regulation for wound healing. Hyperbaric Oxygen (HBO) therapy is a method of increasing oxygen delivery to tissues. The therapy improves tissue oxygenation and stimulates the formation of H2O2 as a secondary messenger for Tumour Necrosis Factor alpha (TNF α), e-NOS, VEGF and Nuclear Factor Kappa Beta phosphorylation (NF-Kb) which play an important role in the rapid transcription of a wide variety of genes in response to extracellular stimuli. This study aims to determine the effects of Hyperbaric Oxygen therapy in enhancing the expressions of e-NOS, TNF-α, VEGF and wound healing. This study is an animal study with a 'randomized control group of pre-test and post test design' on 28 Wistar rats. Randomly, the rats were divided into 4 groups with 7 rats in each group. The HBO treatment group 1 received 5 sessions of HBO 2.4 ATA in 3 × 30 minutes; the HBO treatment group 2 received 10 sessions of HBO 2.4 ATA in 3 × 30 minutes; and each of the control groups were without HBO. Each of the 28 male rats were given a full thickness excisional wound of 1 × 1cm. Examinations of e-NOS, TNF-α, VEGF expressions and wound healing were performed on day-0 (pre-HBO) and day-5 HBO or on day-0 (pre-HBO) and day-10 HBO. The resultsshowthat the Hyperbaric Oxygen therapy can improve e-NOS (p=0.02), TNF-α (p= 0.02), VEGF expression (p=0.02) and wound healing (p=0.002) significantly in the provision of HBO 2.4 ATA for 3 × 30 minutes in 5 sessions over 5 consecutive days. While the 10 sessions of HBO 2.4 ATA for 3 × 30 minutes over 10 consecutive days only increase e-NOS (p=0.02), TNF-α (p=0.04), VEGF expression significantly (p=0.03) but do not improve wound healing significantly (p=0.3) compared with no HBO. The study concludes that HBO can improve the expressions of e-NOS, TNF-α, VEGF and wound healing in the provision of HBO 2.4 ATA for 3 × 30 minutes in 5 sessions, while the 10 sessions of HBO 2.4 ATA for 3 × 30 minutes only increase e-NOS, TNF-α, VEGF expression but do not improve wound healing.

Background and Aim: Antibiotics that increase growth have long been employed as a component of chicken growth. Long-term, unchecked usage may lead to microbial imbalance, resistance, and immune system suppression. Probiotics are a suitable and secure feed additive that may be provided as a solution. The objective of this research was to ascertain the effects of dietary multistrain probiotics (Lactobacillus acidophilus, Bifidobacterium spp., and Lactobacillus plantarum) on the morphology (length and weight) of reproductive organs and productivity performance of laying hens during the early stage of laying. Materials and Methods: One hundred ISA Brown commercial layer chicks of the same body weight (BW) that were 5 days old were divided into five treatments, each with four replicates and four chicks in each duplicate. There were five different dietary interventions: (T1) 100% base feed; (T2) base feed with 2.5 g of antibiotic growth promoter/kg feed; (T3) base feed plus probiotics; (T4) base feed at 1 mL/kg with probiotics; and (T5) base feed with probiotics, 3 mL/kg feed, 5 mL/kg of feed. The parameters observed were performance, internal and exterior egg quality, and the morphology (length and weight) of laying hens’ reproductive organs. Results: Probiotic supplementation (L. acidophilus, Bifidobacterium, and L. plantarum) significantly affected the BW, feed intake, egg weight, yolk index, albumin index, Haugh unit, egg height, egg width, and morphology (length and weight) of laying hens’ reproductive organs compared to the control group (basic feed). In addition, there was no discernible difference between treatment groups in theeggshell weight and thickness variables across all treatment groups. Conclusion: When laying hens were between 17 and 21 weeks old, during the early laying period, microbiota inoculum supplements (L. acidophilus, Bifidobacterium, and L. plantarum) increased growth, the quality of the internal and external layers’ eggs, and the morphology of the laying hens’ reproductive organs.
