Clostridium perfringens is a Gram-positive, anaerobic, spore-forming bacterium that can induces gas gangrene or enteritis in poultry and humans and many other mammalian species. Here, we report an outbreak of C. perfringens type A and type C coinfection in wild boars ( Sus scrofa ). In February 2016, 10 dead wild boars, including two fresh carcasses, were found in Zhaosu County, Xinjiang Province, People's Republic of China. The two fresh carcasses were included in this study. Two strains of C. perfringens were isolated, identified, genotyped, and phylogenetically analyzed...

Kyasanur forest disease (KFD) is a rare tick borne zoonotic disease that causes acute febrile hemorrhagic illness in humans and monkeys especially in southern part of India. The disease is caused by highly pathogenic KFD virus (KFDV) which belongs to member of the genus Flavivirus and family Flaviviridae. The disease is transmitted to monkeys and humans by infective tick Haemaphysalisspinigera. Seasonal outbreaks are expected to occur during the months of January to June. The aim of this paper is to briefly summarize the epidemiology, mode of transmission of KFD virus, clinical findings, diagnosis, treatment, control and prevention of the disease...

H9N2 avian influenza viruses are primarily a disease of poultry; however, they occasionally infect humans and are considered a potential pandemic threat. Little work has been performed to assess the intrinsic biochemical properties related to zoonotic potential of H9N2 viruses. The objective of this study, therefore, was to investigate H9N2 haemagglutinins (HAs) using two well-known correlates for human adaption: receptor-binding avidity and pH of fusion. Receptor binding was characterized using bio-layer interferometry to measure virus binding to human and avian-like receptor analogues and the pH of fusion was assayed by syncytium formation in virus-infected cells at different pHs...

Brucellosis (Brucella bovis) in sika deer ( Cervus nippon ) can cause enormous losses to stag breeding, especially in areas in which stag breeding has become an important industry. It also poses a threat to humans because it is a zoonotic disease. Use of the loop-mediated isothermal amplification (LAMP) assay has been poorly described in the diagnosis of brucellosis in deer. We developed a LAMP assay targeting the omp25 gene sequence to detect brucellosis (Brucella bovis) in sika deer. The reaction can be completed in 60 min at 63 C and, with a detection limit of 17 pg, it was more sensitive than conventional PCR, with its detection limit of 1...

Rabies is an essentially 100% fatal, zoonotic disease, caused by Lyssaviruses. Currently, the disease is vaccine-preventable with pre- and post-exposure prophylaxis (PrEP and PEP). Still, rabies virus is estimated to cause up to 60,000 human deaths annually, of which the vast majority occurs in rural Asia and Africa, due to the inaccessibility of prophylaxis and non-existence of treatment. Despite these unmet clinical needs, rabies control mainly focuses on the sylvatic reservoir and drug innovation receives relatively little attention compared to other neglected tropical diseases (NTDs)...

Chlamydia psittaci, an obligate intracellular gram-negative bacteria, causes an important zoonotic disease in humans, namely, psittacosis. The objective of this study was to determine the persistent viability of C. psittaci at various temperature conditions. The cloacal swab samples were collected from feral and racing pigeons to find a C. psittaci field strain. The bacterial isolation showed that 1.3% of feral pigeons were PCR positive, while all samples of racing pigeons were PCR negative. Also, bacterial characterization suggested that it belonged to genotype B, which had bacterial titers 3...

Simian T-lymphotropic virus 1 (STLV-1) enters human populations through contact with non-human primate (NHP) bushmeat. We tested whether differences in the extent of contact to STLV-1 infected NHP bushmeat foster regional differences in prevalence of human HTLV-1. Using serological and PCR assays, we screened humans and NHP at two sub-Saharan African sites where subsistence hunting was expected to be less (Taï region, Côte d'Ivoire, CIV) or more developed (Bandundu region, Democratic Republic of the Congo, DRC)...

Brucellosis is one of the most common zoonoses globally, and Central Asia remains a Brucella hotspot. The World Health Organization classifies brucellosis as a neglected zoonotic disease that is rarely in the spotlight for research and mainly affects poor, marginalized people. Urban and peri-urban farming is a common practice in many low-income countries, and it increases the incomes of families that are often restrained by limited economic resources. However, there is a concern that the growing number of people and livestock living close together in these areas will increase the transmission of zoonotic pathogens such as Brucella...

H5N6 is a highly pathogenic avian influenza (HPAI) and a zoonotic disease that causes recurring endemics in East Asia. At least 155 H5N6 outbreaks, including 15 human infections, have been reported in China. These repeated outbreaks have increased concern that the H5N6 virus may cross over to humans and cause a pandemic. In February, 2016, peafowls in a breeding farm exhibited a highly contagious disease. Post-mortem examinations, including RT-PCR, and virus isolation, confirmed that the highly pathogenic H5N6 influenza virus was the causative agent, and the strain was named A/Pavo Cristatus/Jiangxi/JA1/2016...

OBJECTIVE: Being a notifiable and zoonotic disease, Q-fever is coming under increasing focus of epizootic disease control. Current studies indicate that the disease is more widespread in Germany than the number of notifications suggest. Therefore, since 2013, under certain conditions a hardship allowance is granted by the Animal Diseases Fund of Lower Saxony for the vaccine costs of the basic immunization to support affected farms. Material und methods: All farmers, on whose farms clinical signs of Q-fever and the pathogen Coxiella burnetii had been detected prior to vaccination and who had taken advantage of the hardship allowance during the previous 2 years were surveyed to assess the effectiveness of the measure...

Free-living raptors (birds of prey) can act as reservoirs of potentially zoonotic agents but they also can be affected by microorganisms as target hosts. In this retrospective study, microbiological results (n=663) and antibiotic sensitivity profiles (n=108) of bacterial isolates were analyzed from diseased free-living raptors. Sixty-nine percent of cases (n=457) yielded bacteria: 58% were in pure culture and 42% were of different species. Remarkably, samples from necropsies (47%) had higher percentage of pure isolations than those obtained from clinical (31%) samples (p<0...

Human factors, including contact structure, movement, impact on the environment and patterns of behaviour, can have significant influence on the emergence of novel infectious diseases and the transmission and amplification of established ones. As anthropogenic climate change alters natural systems and global economic forces drive land-use and land-cover change, it becomes increasingly important to understand both the ecological and social factors that impact infectious disease outcomes for human populations...

Cystic echinococcosis (CE) is a chronic and complex zoonotic disease. Information on the mechanisms involved in parasite establishment, growth and persistence remain limited. These may be modulated by a crosstalk between extracellular vesicles (EVs). EVs including exosomes and microvesicles are able to carry developmental signaling proteins which coordinate growth and establishment of several parasites. Here, an exosome enriched EV fraction was isolated from hydatid fluid (HF) of fertile sheep cysts. A proteomic analysis of this fraction identified a number of parasite-derived vesicle-membrane associated proteins as well as cytosolic proteins...

Brucellosis, the most common zoonotic disease worldwide, represents a great threat to animal husbandry with the potential to cause enormous economic losses. Brucellosis has become a major public health problem in China, and the number of human brucellosis cases has increased dramatically in recent years. In order to evaluate different intervention strategies to curb brucellosis transmission in China, a novel mathematical model with a general indirect transmission incidence rate was presented. By comparing the results of three models using national human disease data and 11 provinces with high case numbers, the best fitted model with standard incidence was used to investigate the potential for future outbreaks...

Infectious diseases are a significant burden on public health and economic stability of societies all over the world. They have for centuries been among the leading causes of death and disability and presented growing challenges to health security and human progress. The threat posed by infectious diseases is further deepened by the continued emergence of new, unrecognized, and old infectious disease epidemics of global impact. Over the past three and half decades at least 30 new infectious agents affecting humans have emerged, most of which are zoonotic and their origins have been shown to correlate significantly with socioeconomic, environmental, and ecological factors...
