Orbivirus RNA in a Banana Serotine (Afronycteris nanus) Bat in the Republic of the Congo
AbstractOrbiviruses are arthropod borne viruses of vertebrates, with some of them being important pathogens of veterinary, conservation and economic importance, while others are occasionally associated with human disease. Some apparently bat specific orbiviruses have been detected, but little is known about their distribution and diversity. We thus sampled and screened 52 bats living in the Congo Basin, and detected RNA indicative of a novel orbivirus in a single banana serotine (Afronycteris nanus) by PCR. The detected RNA clusters with epizootic haemorrhagic disease virus, bluetongue virus, and others. The findings highl...

The Movement of Pathogen Carrying Flies at the Human –Wildlife Interface
AbstractFlies form high-density associations with human settlements and groups of nonhuman primates and are implicated in transmitting pathogens. We investigate the movement of nonhuman primate-associated flies across landscapes surrounding Kibale National Park, Uganda, using a mark –recapture experiment. Flies were marked in nine nonhuman primate groups at the forest edge (\(\overline{x}\) = 929 flies per group), and we then attempted to recapture them in more anthropized areas (50 m, 200 m and 500 m from where marked; 2–21 days after marking). Flies marked in nonhuman primate groups were recaptured in human a...

Down the Rabbit Hole: Domestic Rabbit Owners ’ Perceptions of Rabbit Hemorrhagic Disease Virus 2
AbstractRabbit hemorrhagic disease virus 2 (RHDV2) is a highly contagious pathogen that infects wild and domestic rabbits and hares (lagomorphs). Globally, RHDV2 has resulted in substantial economic losses for commercial rabbit trade and caused wild lagomorph population declines. Previous research on RHDV2 suggests that human-mediated movement of rabbits may contribute to the spread of RHDV2. We conducted the first survey of individuals who own or interact with domestic rabbits to identify their rabbit husbandry behaviors and knowledge of, and concerns about, RHDV2. In 2021, we surveyed 1807 rabbit owners, breeders, and re...

Batrachochytrium salamandrivorans ’ Amphibian Host Species and Invasion Range
AbstractBatrachochytrium salamandrivorans (Bsal), a species related to the destructive pathogenBatrachochytrium dendrobatidis (Bd), was found and identified in Europe in 2013. Now, a decade later, a large amount of information is available. This includes data from studies in the field, reports of infection in captive amphibians, laboratory studies testing host susceptibility, and data from prospective studies that test forBsal’s presence in a location. We conducted a systematic review of the published literature and compiled a dataset ofBsal tests. We identified 67 species that have been reported positive forBsal, 20 of ...

A Novel Host of an Emerging Disease: SARS-CoV-2 Infection in a Giant Anteater (Myrmecophaga tridactyla) Kept Under Clinical Care in Brazil
AbstractA young male free-ranging giant anteater (Myrmecophaga tridactyla) was found with paralysis of pelvic limbs on a highway and kept under human care. Radiographs confirmed multiple incomplete fractures in the thoracolumbar vertebrae. Due to the poor prognosis, euthanasia was chosen. The infection was established by viral SARS-CoV-2 RNA detection in the rectal swab, spleen and kidney samples. Immunohistochemistry detected the viral nucleocapsid protein in sections of the lungs, liver, spleen, lymph nodes, and large intestine sections, and spike protein antigen in the lung tissue. Pilosa order species should be include...

Aetiology and Potential Animal Exposure in Central Nervous System Infections in Vietnam
AbstractAn estimated 73% of emerging infections are zoonotic in origin, with animal contact and encroachment on their habitats increasing the risk of spill-over events. In Vietnam, close exposure to a wide range of animals and animal products can lead to acquisition of zoonotic pathogens, a number of which cause central nervous system (CNS) infections. However, studies show the aetiology of CNS infections remains unknown in around half of cases. We used samples and data from hospitalised patients with CNS infections, enrolled into the Vietnam Initiative on Zoonotic Infections multicentre study, to determine the association...
