Using music to assist language learning in autistic children with minimal verbal language: The MAP feasibility RCT.

Research has shown that autistic individuals often have unusually good musical skills and that combining words and music helps autistic individuals to focus on spoken words. This study tests the idea that music will help with early language learning of preschool autistic children. The results show that when caregivers sing words to autistic children, the children pay more attention to the caregiver than when the words are spoken and that they learn word combinations more easily.

Histopathologic and molecular characterization of papillomavirus 1 and papillomavirus 2 infection in North American porcupines ().

papillomavirus 1 (EdPV1) and papillomavirus 2 (EdPV2) are associated with cutaneous papillomas in North American porcupines (). This study defined gross, histopathologic, and molecular characteristics of viral papillomas in 10 North American porcupines submitted to the New York State Animal Health Diagnostic Center. Investigation for the presence of EdPV1 and EdPV2 DNA via polymerase chain reaction (PCR) was performed in 9 of the 10 (90.

Susceptibility of white-tailed deer () to SARS-CoV-2.

The origin of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus causing the global coronavirus disease 19 (COVID-19) pandemic, remains a mystery. Current evidence suggests a likely spillover into humans from an animal reservoir. Understanding the host range and identifying animal species that are susceptible to SARS-CoV-2 infection may help to elucidate the origin of the virus and the mechanisms underlying cross-species transmission to humans.

Active surveillance of pathogens from ticks collected in New York State suburban parks and schoolyards.

Schoolyards and suburban parks are two environments where active tick surveillance may inform local management approaches. Even in a state such as New York with a robust active tick surveillance programme operated by the state Department of Health, these settings are not routinely covered. The goal of this study was to highlight the importance of active surveillance for tick-borne pathogens by describing their prevalence in ticks collected from schoolyards and suburban parks and to guide the use of integrated pest management in these settings.

Equine pegiviruses cause persistent infection of bone marrow and are not associated with hepatitis.

Pegiviruses frequently cause persistent infection (as defined by >6 months), but unlike most other Flaviviridae members, no apparent clinical disease. Human pegivirus (HPgV, previously GBV-C) is detectable in 1-4% of healthy individuals and another 5-13% are seropositive. Some evidence for infection of bone marrow and spleen exists.

First report of equine parvovirus-hepatitis-associated Theiler's disease in Europe.

Background: Equine parvovirus-hepatitis (EqPV-H) has been proposed as the aetiological cause of Theiler's disease, also known as serum hepatitis. EqPV-H-associated Theiler's disease has not been previously reported in Europe.

Objectives: To determine whether EqPV-H infection was associated with a 2018-2019 outbreak of Theiler's disease in four horses on a studfarm.

DETECTION OF SKUNK ADENOVIRUS 1 IN TWO NORTH AMERICAN PORCUPINES () WITH RESPIRATORY DISEASE.

Adenoviruses have been reported to affect a broad range of host species, tend to be species specific, and often affect the respiratory system. This report describes the isolation of an adenovirus from deep nasal swabs of two wild North American porcupines () with respiratory diseases that presented to a wildlife hospital. Partial sequences of the deoxyribonucleic acid polymerase gene of the isolated virus were identical to skunk adenovirus (SkAdV-1), also known as pygmy marmoset adenovirus.

A NOVEL ORTHOREOVIRUS ASSOCIATED WITH EPIZOOTIC NECROTIZING ENTERITIS AND SPLENIC NECROSIS IN AMERICAN CROWS ().

Epizootic mortalities in American Crows () during the winter months, referred to as winter mortality of crows, have been recorded in North America for almost two decades. The most common postmortem findings include necrotizing enteritis, colitis, and fibrinous splenic necrosis. These findings are proposed to be due to infection with a sp.

Oral Capillariosis Due to in Migrating Sharp-shinned Hawks () in New York, USA, 2016-18.

Oral lesions focused around the oral commissures were documented in several Sharp-shinned Hawks () in the 2016-18 spring migration season at a banding station located on the southern shore of Lake Ontario, New York, US. Samples of the inflamed and caseous lesions repeatedly tested negative for and poxvirus; however, large numbers of capillariid eggs and embedded worms were consistently present. Morphologically, the nematodes were identified as , which was confirmed by PCR and genetic sequencing.

Viral testing of 18 consecutive cases of equine serum hepatitis: A prospective study (2014-2018).

Background: Three flaviviruses (equine pegivirus [EPgV]; Theiler's disease-associated virus [TDAV]; non-primate hepacivirus [NPHV]) and equine parvovirus (EqPV-H) are present in equine blood products; the TDAV, NPHV, and EqPV-H have been suggested as potential causes of serum hepatitis.

Objective: To determine the prevalence of these viruses in horses with equine serum hepatitis.

Animals: Eighteen horses diagnosed with serum hepatitis, enrolled from US referral hospitals.

Viral testing of 10 cases of Theiler's disease and 37 in-contact horses in the absence of equine biologic product administration: A prospective study (2014-2018).

Background: A novel equine parvovirus (EqPV-H) was recently discovered in the equine liver with Theiler's disease.

Objectives: To determine the prevalence of EqPV-H infection in naturally occurring Theiler's disease cases and in-contact horses in the absence of historical equine biologic product administration.

Animals: Ten cases of Theiler's disease from 6 separate properties were included in the study, based on the criteria of acute onset of clinical signs of liver failure with laboratory or histopathologic findings characteristic of Theiler's disease and no history of receiving an equine biologic product within the preceding 4 months.

New Parvovirus Associated with Serum Hepatitis in Horses after Inoculation of Common Biological Product.

Equine serum hepatitis (i.e., Theiler's disease) is a serious and often life-threatening disease of unknown etiology that affects horses.

Parvovirus Infection Is Associated With Myocarditis and Myocardial Fibrosis in Young Dogs.

Perinatal parvoviral infection causes necrotizing myocarditis in puppies, which results in acute high mortality or progressive cardiac injury. While widespread vaccination has dramatically curtailed the epidemic of canine parvoviral myocarditis, we hypothesized that canine parvovirus 2 (CPV-2) myocardial infection is an underrecognized cause of myocarditis, cardiac damage, and/or repair by fibrosis in young dogs. In this retrospective study, DNA was extracted from formalin-fixed, paraffin-embedded tissues from 40 cases and 41 control dogs under 2 years of age from 2007 to 2015.

Development and validation of a highly sensitive real-time PCR assay for rapid detection of parapoxviruses.

Parapoxviruses (PaPVs) cause widespread infections in ruminants worldwide. All PaPVs are zoonotic and may infect humans after direct or indirect contact with infected animals. Herein we report the development and validation of a highly sensitive real-time PCR assay for rapid detection of PaPVs.

High-throughput Detection of Respiratory Pathogens in Animal Specimens by Nanoscale PCR.

Nanoliter scale real-time PCR uses spatial multiplexing to allow multiple assays to be run in parallel on a single plate without the typical drawbacks of combining reactions together. We designed and evaluated a panel based on this principle to rapidly identify the presence of common disease agents in dogs and horses with acute respiratory illness. This manuscript describes a nanoscale diagnostic PCR workflow for sample preparation, amplification, and analysis of target pathogen sequences, focusing on procedures that are different from microliter scale reactions.

Characterisation of potato crisp effective porosity using micro-CT.

Background: The effective porosity is an important quantitative parameter for food products that has a significant effect on taste and quality. It is challenging to quantify the apparent porosity of fried potato crisps as they have a thin irregularly shaped cross section containing oil and water. This study uses a novel micro-CT technique to determine the solid volume fraction and hence the effective porosity of three types of potato crisps: standard continuously fried crisps, microwaved crisps, and continuously fried 'kettle' crisps.

Characterization of nonprimate hepacivirus and construction of a functional molecular clone.

Nonprimate hepacivirus (NPHV) is the closest known relative of hepatitis C virus (HCV) and its study could enrich our understanding of HCV evolution, immunity, and pathogenesis. High seropositivity is found in horses worldwide with ∼ 3% viremic. NPHV natural history and molecular virology remain largely unexplored, however.

Safety and immunogenicity of Ontario Rabies Vaccine Bait (ONRAB) in the first us field trial in raccoons (Procyon lotor).

In 2011, we conducted a field trial in rural West Virginia, USA to evaluate the safety and immunogenicity of a live, recombinant human adenovirus (AdRG1.3) rabies virus glycoprotein vaccine (Ontario Rabies Vaccine Bait; ONRAB) in wild raccoons (Procyon lotor) and striped skunks (Mephitis mephitis). We selected ONRAB for evaluation because of its effectiveness in raccoon rabies management in Ontario and Quebec, Canada, and significantly higher antibody prevalence rates in raccoons compared with a recombinant vaccinia-rabies glycoprotein (V-RG) vaccine, Raboral V-RG®, in US-Canada border studies.

Detection of canine pneumovirus in dogs with canine infectious respiratory disease.

Canine pneumovirus (CnPnV) was recently identified during a retrospective survey of kenneled dogs in the United States. In this study, archived samples from pet and kenneled dogs in the United Kingdom were screened for CnPnV to explore the relationship between exposure to CnPnV and the development of canine infectious respiratory disease (CIRD). Within the pet dog population, CnPnV-seropositive dogs were detected throughout the United Kingdom and Republic of Ireland, with an overall estimated seroprevalence of 50% (n = 314/625 dogs).

Antenatal screening for Down syndrome: a quantitative demonstration of the improvements over the past 20 years.

Objectives: Pregnant women who receive a high screening risk result for Down, Edwards or Patau syndrome are offered diagnostic tests that carry a procedure-related risk of miscarriage. This study quantifies the improvement in the screening tests by calculating the number of women who had such tests per syndrome diagnosis from 1991 to 2010.

Methods: Routinely stored data on prenatal chorionic villus sampling (CVS) and amniocentesis samples performed from 1991 to 2010 from the Wessex Regional Genetics Laboratory in England were extracted from the laboratory database.

Novel pneumoviruses (PnVs): Evolution and inflammatory pathology.

A previous report of a novel pneumovirus (PnV) isolated from the respiratory tract of a dog described its significant homology to the rodent pathogen, pneumonia virus of mice (PVM). The original PnV-Ane4 pathogen replicated in and could be re-isolated in infectious state from mouse lung but elicited minimal mortality compared to PVM strain J3666. Here we assess phylogeny and physiologic responses to 10 new PnV isolates.

Complete genome sequence of a polyomavirus isolated from horses.

A polyomavirus was isolated from the eyes of horses, and the sequence was determined. A nearly identical VP1 sequence was amplified from the kidney of another animal. We report the complete genome sequence of the first polyomavirus to be isolated from a horse.

Genome characterization of Salem virus reveals its evolutionary intermediate status in the subfamily Paramyxovirinae.

Salem virus (SalPV) was originally isolated from a horse during a disease outbreak in 1992 in the USA. In this study, we complete the genome characterization of SalPV and confirm the classification of this virus as a member of the subfamily Paramyxovirinae. The SalPV genome is 16,698 nucleotides in length, with six transcriptional units in the order 3'-N/P/V/C-M-F-G-L-5'.
