First detection of Salmonella spp. in backyard production farms from central Chile

Characteristics and conditions of backyard production systems (BPS) transform them into potential maintainers of priority zoonotic agents, like Salmonella spp., highly important agent because of its impact in animal and public health. 

Objective

The purpose of this study was to detect the presence of circulating Salmonella spp. on backyard production systems (BPS) with poultry or swine breeding in central Chile

What do we know about the behavior of animal rabies in Chile through the last years?

Rabies is a zoonotic disease caused by an RNA virus from the family Rhabdoviridae, genus Lyssavirus. Worldwide distributed, control of rabies has been considered to be particularly amenable to a “One Health” strategy (1). In Chile, rabies was considered endemic in domestic dog population until the late 1960s, when a surveillance program was established, decreasing the number of human cases related to canine variants until the year 1972 (2). Rabies is recognized as a endemic infection in chiropterans of Chile and prompted the surveillance of the agent in this and other species (3).

Exploring the Distribution of Coccidioides immitis in South Central Washington State

Coccidioidomycosis, commonly referred to as Valley Fever, is caused by the soil-borne saprophytic fungus C. immitis and posadasii. These species have historically been found in the desert southwest and Mexico; however, in 2010 there were three coccidioidomycosis cases identified in central Washington. Colonization of soils by C. immitis has been confirmed at exposure sites associated with these cases. Multiple studies have identified a relationship between environmental conditions and C. immitis growth areas, but these relationships have not been evaluated in Washington.

Activity of Natural Tularemia Foci in West Ukraine

Annually sporadic cases of tularemia in humans are registered in Ukraine and new enzootic areas are found. Monitoring of tularemia natural foci is important given the potential significant financial losses in case of tularemia outbreaks and taken into account that this pathogen can be used as a bioterrorist agent.

Objective

Study the activity of natural foci of tularemia and identify the main types of reservoirs and vectors of Francisella tularensis.

Improving Cattle Market Syndromic Surveillance Through Electronic Data Capture

An active syndromic surveillance system was designed to collect cattle health information from a sample of Texas cattle market sales. Texas Animal Health Commission livestock inspectors record the total number of animals observed along with the total number displaying clinical signs of interest grouped into body system categories (e.g. respiratory, neurologic, etc.). Inspection reports are submitted to the United States Department of Agriculture Veterinary Services (VS) Risk Identification Team for monitoring.

Immune response and distribution of antigen in chickens after infection LPAIV (H4N6)

Influenza is a serious problem for the health of people, animals and birds. Therefore, comprehensive study of influenza virus, its natural reservoir, pathogenesis and immune response will provide further opportunity to ensure protection for animals, birds and people from this infection. 

Objective

To study the immune response in chicken on the administration of LPAIV isolated from the natural reservoir.

Identifying Key Transmission Route of Avian Influenza A(H9N2) in Live Poultry Markets

Live poultry markets (LPMs) continue to operate in many Asian countries. Low pathogenic avian influenza (LPAI) viruses are often endemic in the poultry, and LPM presents the opportunity for human-poultry interactions and potential human infections with avian influenza viruses.

Influenza study of backyard animals in Georgia

Aquatic birds are the main reservoirs of influenza viruses, however, pigs represent an essential host in virus ecology as they are susceptible to both avian and human influenza viruses. Circulating zoonotic influenza (A/H7N9, A/H5N1, and A/H3N2v) viruses could mutate into forms easily transmissible from human-to-human and become a public health concern. Georgia is located along routes used by migrating birds where different species of aquatic birds are found. In 2006, highly pathogenic influenza virus A/H5N1 was detected in two wild swans in Adjara (western Georgia).

Animal Surveillance: Use of Animal Health Data to Improve Global Disease Surveillance

Since the majority of emerging infectious diseases over the past several decades have been zoonotic, animal health surveillance is now recognized as a key element in predicting public health risks. Surveillance of animal populations can provide important early warnings of emerging threats to human populations from bioterrorism or naturally occurring infectious disease epidemics. This study investigated current animal data collection and surveillance systems, isolated major gaps in state and national surveillance capabilities, and provided recommendations to fill those gaps.

Detection of brucellosis through active surveillance, Armenia, 2014

Brucellosis is a serious disease caused by bacteria of the Brucella genus. It principally affects ruminants but may be transmitted to humans. Registration of cases in cattle farms causes considerable economic losses and creates favorable conditions for mass infection among humans. In Armenia the expansion of animal industries and urbanization are the main reasons for occurrence and development of brucellosis.

Objective

In the spring of 2014, people from vulnerable households in all marzes of Armenia were examined with the aim of active surveillance.
