“…Immunoassay based on nanotechnology has also been developed that can detect minute quantities of Listeria in environmental samples (Jaakohuhta et al 2007). Recent progress in molecular detection techniques, comprising PCR, real-time PCR, multiplex PCR, LAMP, recombinant protein-based diagnostics, biosensors, biochips, microarrays, gene sequencing, phylogenetic analysis and nanodiagnostics, needs to be further exploited to their full practical potentials (Schmitt and Henderson 2005;Bollo 2007;Bergquist 2011;Deb and Chakraborty 2012;Dhama, Karthik, et al 2014;Verma et al 2014). …”

Listeriosis is an infectious and fatal disease of animals, birds, fish, crustaceans and humans. It is an important food-borne zoonosis caused by Listeria monocytogenes, an intracellular pathogen with unique potential to spread from cell to cell, thereby crossing blood-brain, intestinal and placental barriers. The organism possesses a pile of virulence factors that help to infect the host and evade from host immune machinery. Though disease occurrence is sporadic throughout the world, it can result in severe damage during an outbreak. Listeriosis is characterized by septicaemia, encephalitis, meningitis, meningoencephalitis, abortion, stillbirth, perinatal infections and gastroenteritis with the incubation period varying with the form of infection. L. monocytogenes has been isolated worldwide from humans, animals, poultry, environmental sources like soil, river, decaying plants, and food sources like milk, meat and their products, seafood and vegetables. Since appropriate vaccines are not available and infection is mainly transmitted through foods in humans and animals, hygienic practices can prevent its spread. The present review describes etiology, epidemiology, transmission, clinical signs, post-mortem lesions, pathogenesis, public health significance, and advances in diagnosis, vaccines and treatment of this disease. Special attention has been given to novel as well as prospective emerging therapies that include bacteriophage and cytokine therapy, avian egg yolk antibodies and herbal therapy. Various vaccines, including advances in recombinant and DNA vaccines and their modes of eliciting immune response, are also discussed. Due focus has also been given regarding appropriate prevention and control strategies to be adapted for better management of this zoonotic disease.

“…Till now, no commercial diagnostic tests exist for diagnosing this viral infection. Advances in diagnostic techniques need to be applied for Zika virus detection viz., multiplex PCR, LAMP, recombinant diagnostics, gene sequencing and phylogenetic analysis, biosensors, biochips, microarrays, and nanotechnologybased diagnostics (Jain 2007;Kawadkar et al 2011;Dhama, Karthik, et al 2014;Ratcliff et al 2007;Bergquist 2011;Van den Hurk and Evoy 2015). Apart from these newer tools for extensive epidemiological and surveillance studies, alternatives need to be explored for tracking and monitoring Zika virus infections and spread, such as geographical information system and establishing networking programs to counter this important pathogen.…”

This review converses the Zika virus which has attained global concern due to its rapid pandemic potential and impact on humans. Though Zika virus was first isolated in 1947, till the recent large-scale outbreak which occurred in Micronesia, in 2007, the virus was placed into the innocuous pathogen category. The World Health Organization on 1 February 2016 declared it as a 'Public Health Emergency of International Concern.' Of the note, American as well as Pacific Island strains/isolates is relatively closer to Asian lineage strains. The African and American strains share more than 87.5% and 95% homologies with Asian strains/isolates, respectively. Asian strains form independent clusters, except those isolated from China, suggesting relatively more diversity than African strains. Prevention and control are mainly aimed at the vector population (mosquitoes) with Aedes aegypti being the main species. Surveys in Africa and Asia indicated seropositivity in various animal species. However, so far its natural reservoir is unknown. There is an urgent need to understand why Zika virus has shifted from being a virus that caused mild illness to unforeseen birth defects as well as autoimmune-neurological problems. Unfortunately, an effective vaccine is not available yet. Availability of cryo-electron microscopy based on 3.8 A resolution revealing mature Zika virus structure and the probable virus attachment site to host cell would provide critical insights into the development of antiviral treatments and vaccines.

“…This also requires follow up of the real concepts of One world One health One medicine, international co-ordination and networking, adapting advances in disease diagnosis and control measures and implementation of good management practices including strict biosecurity practices (Schmitt and Henderson, 2005;Bergquist, 2011;Bollo, 2007;Deb and Chakraborty, 2012;Dhama et al, 2013dSingh et al, 2014a).…”

| Johne's disease ( JD) or Paratuberculosis is one of the most wide-spread, highly prevalent and economically devastating infectious diseases of domestic livestock worldwide. It is caused by Mycobacterium avium subspecies paratuberculosis (MAP). Disease is endemic in the domestic livestock, and is a spectral disease characterized by long sub-clinical phase without signs of infection. Therefore control of disease is difficult and offers challenges at both scientific and management levels. Since disease is incurable, control of paratuberculosis has emerged as a new science and is continuously evolving in last two decades. Present paper reviews the National disease control programs that are in practice in different countries around the world.
