Campylobacteriosis is an important zoonotic disease and the prevalence of Campylobacter is largely unknown in the wildlife of India. A total of 370 samples, comprising of 314 fresh faecal samples from apparently healthy captive wild animals and birds, 30 stool swabs from animal care takers and 26 samples of the animals' food and water were collected from G. B. Pant High Altitude Zoo, Nainital, Kanpur Zoo, Wildlife Park, IVRI and the Post Graduate Research Institute in Animal Sciences (PGRIAS), Chennai, Tamilnadu from August 2014 to May 2015. Samples were processed for cultural isolation, direct PCR and multiplex PCR for species confirmation. To decipher the genetic diversity, the 16S rRNA gene was amplified, sequenced and analyzed. Based on isolation, the overall occurrence rate of spp. was 0.8% (3/370), being 2.94% (3/102) for captive wild birds. Three Campylobacter were isolated from silver pheasants, lady amherest pheasants and saras cranes. Direct PCR assay showed the overall occurrence rate of spp. to be 4.77% (15/315), being 1.58% (2/126) for captive wild ruminants, 5.81% (5/86) for non-ruminants and 7.84% (8/102) for birds. All the isolates were identified as .

Introduction: Small mammals, especially rodents and bats, are known reservoirs of zoonotic viruses, but little is known about the viromes of insectivorous species including hedgehogs (order Eulipotyphla), which often live near human settlements and come into contact with humans.
Methods: We used high-throughput sequencing and metaviromic analysis to describe the viromes of 21 hedgehogs (Erinaceus sp.) sampled from summer 2022 to spring 2023.

Birds of prey raised in captivity have direct contact with the environment and are fed raw meat various animals, which increases the risk of infections caused by parasites, including endoparasites. The aim of this study was to evaluate the prevalence of endoparasites in predatory birds of the orders Accipitriformes and Falconiformes that are used in falconry in Poland. Fresh feces were sampled from 52 birds, including 16 saker falcons (Falco cherrug), 8 lanner falcons (Falco biarmicus), 7 peregrine falcons (Falco peregrinus), 8 Harris's hawks (Parabuteo unicinctus), 7 Eurasian goshawks (Accipiter gentilis), 3 common kestrels (Falco tinnunculus), 1 Eurasian sparrowhawk (Accipiter nisus), 1 red-tailed hawk (Buteo jamaicensis), and 1 common buzzard (Buteo buteo).

Freshwater environments are biodiversity hotspots under multiple pressures, including pesticide exposure. S-metolachlor, a widely used herbicide, can induce genotoxic, cytotoxic and physiological effects in captive fish, but we have a limited understanding of the effects of exposure to S-metolachlor in free-living vertebrates. We carried out an original field experiment using integrative approaches across biological levels and temporal scales.

The investigation of wildlife trade and crime has benefitted from advances in technology and scientific development in a variety of fields. Stable isotope analysis (SIA) represents one rapidly developing approach that has considerable potential to contribute to wildlife trade investigation, especially in complementing other methods including morphological, genetic, and elemental approaches. Here, we review recent progress in the application of SIA in wildlife trade research to highlight strengths, shortcomings, and areas for development in the future.
