Portable reduced graphene oxide biosensor for detection of rabies virus in bats using nasopharyngeal swab samples
Biosens Bioelectron. 2023 Mar 31;232:115291. doi: 10.1016/j.bios.2023.115291. Online ahead of print.ABSTRACTRabies is a lethal zoonotic disease caused by rabies virus (RABV) that affects human health and the economy. RABV is transmitted mainly by bats in Brazil, and surveillance in remote areas is hampered by the difficulty of properly collecting samples during fieldwork and the diagnosis is performed in laboratory conditions. Here, we report a portable electrochemical biosensor based on nucleic acid interactions for RABV detection in nasopharyngeal swab samples. The working electrode of the biosensor is composed of reduce...

Vaccines for prion diseases: a realistic goal?
Cell Tissue Res. 2023 Feb 11. doi: 10.1007/s00441-023-03749-7. Online ahead of print.ABSTRACTPrion diseases are fatal infectious neurodegenerative disorders and prototypic conformational diseases, caused by the conformational conversion of the normal cellular prion protein (PrPC) into the pathological PrPSc isoform. Examples are scrapie in sheep and goat, bovine spongiform encephalopathy (BSE) in cattle, chronic wasting disease (CWD) in cervids, and Creutzfeldt-Jacob disease (CJD) in humans. There are no therapies available, and animal prion diseases like BSE and CWD can negatively affect the economy, ecology, animal healt...

Isolation and Identification of Novel Highly Pathogenic Avian Influenza Virus (H5N8) Subclade 2.3.4.4b from Geese in Northeastern China
Appl Environ Microbiol. 2023 Jan 5:e0157222. doi: 10.1128/aem.01572-22. Online ahead of print.ABSTRACTH5N8, a highly pathogenic avian influenza, has become a new zoonotic threat in recent years. As of December 28, 2021, at least 3,206 H5N8 cases had been reported in wild birds and poultry worldwide. In January 2021, a novel virus strain named A/goose/China/1/2021 was isolated during an H5N8 goose influenza outbreak in northeastern China. The PB2, PB1, HA, and M genes of A/goose/China/1/2021 were highly identical to those of H5N8 strains emerging in Kazakhstan and Russia in Central Asia from August to September 2020, while ...

Determination of seroprevalence of brucellosis in livestock and high-risk population in Kurdistan, Western Iran
DISCUSSION: the current study, provided some valuable information on the seroprevalence of brucellosis in animal and human participants from the west of Iran. Considering the effects of brucellosis on causing reproductive disorders, including abortion, placental retention, andendometritis controlling the infection could have a significant impact on terms of economy.PMID:36603240 | DOI:10.1016/j.cimid.2022.101942

Glanders and brucellosis in equids from the Amazon region, Brazil
Acta Trop. 2022 Mar 27;231:106429. doi: 10.1016/j.actatropica.2022.106429. Online ahead of print.ABSTRACTGlanders and brucellosis are zoonotic infectious diseases that affect equids in several countries worldwide. On Marajó Island (Amazon region of Brazil), Marajoara and Puruca horses, which are well adapted to the climatic and territorial adversities of the region, play a fundamental role in the local economy and in the sociocultural lives of the population. However, these animals have undergone a drastic reduction in number, markedly due to precarious veterinary care, unknown causes of morbidity and mortality, and disor...

Geographical and temporal spread of equine rabies in Brazil
Acta Trop. 2022 Jan 3:106302. doi: 10.1016/j.actatropica.2022.106302. Online ahead of print.ABSTRACTIn Brazil, the horse is frequently used in cultural activities, sports, and in rural and urban work, implementing the economy in different social classes. Among the diseases in horses with zoonotic potential, rabies has been neglected in the country, increasing the risk of spreading the disease across borders. The present study evaluated the spatiotemporal distribution and temporal trend of rabies in horses in Brazil between 2010 and 2019. During this period, 1,290 cases of rabies were detected in horses in Brazil, mainly in...

Climate change and zoonoses: A review of the current status, knowledge gaps, and future trends
The objective of this article is to review the current literature on the observed impacts of climate change on zoonoses and discuss future trends. We evaluated several climate models to assess the projections of various zoonoses driven by the predicted climate variations. Many climate projections revealed potential geographical expansion and the severity of vector-borne, waterborne, foodborne, rodent-borne, and airborne zoonoses. However, there are still some knowledge gaps, and further research needs to be conducted to fully understand the magnitude and consequences of some of these changes. Certainly, by understanding th...
