[Seating, postural support, safety and satisfaction of users of wheelchairs in a CABA Rehabilitation Institute. Descriptive study].

Introduction: In the world, 75 million people require a wheelchair (W/C) but only between 5% and 15% of them have one. The WHO defines a W/C as adequate if it meets the needs of the user and their environment, offers appropriate seating and postural support and if it is safe and durable.

Objective: The primary objective is to describe the seating, postural support and safety of W/Cs users who attend the I.

[Risk factors for the development and recurrence of pressure ulcers in patients with spinal cord injury: A systematic review.].

Introduction: A spinal cord injury refers to the damage suffered in the spinal cord as a result of trauma, disease or degeneration. Every person with spinal cord injury is at risk of developing pressure ulcers, and almost everyone will develop at least one ulcer due to severe pressure during his or her life.

Objective: To identify the studies that detected risk factors for the development and recurrence of pressure ulcers in patients with spinal cord injury; and, if possible, synthesize the evidence to determine whether an association exists between them.

Construction and manipulation of a full-length infectious bacterial artificial chromosome clone of equine herpesvirus type 3 (EHV-3).

Equine herpesvirus type 3 (EHV-3) is the causal agent of equine coital exanthema, a disease characterized by pox-like lesions on the penis of stallions and the vulva of mares. Although the complete genomic sequence of EHV-3 has been recently made available, its genomic content remains poorly characterized and the molecular mechanisms of disease development not yet elucidated. In an attempt to facilitate genetic manipulation of EHV-3, we describe here the construction of a full-length infectious bacterial artificial chromosome (BAC) clone of EHV-3.

Epidemiological and virological findings during multiple outbreaks of equine influenza in South America in 2012.

Background: In 2012, equine influenza (EI) virus was confirmed as the cause of outbreaks of respiratory disease in horses throughout South America. In Uruguay and Argentina, hundreds of vaccinated thoroughbred horses in training and racing facilities were clinically affected.

Objective: To characterise the EI viruses detected during the outbreak in Uruguay and Argentina.

Complete genome sequence of equid herpesvirus 3.

Equid herpesvirus 3 (EHV-3) is a member of the subfamily Alphaherpesvirinae that causes equine coital exanthema. Here, we report the first complete genome sequence of EHV-3. The 151,601-nt genome encodes 76 distinct genes like other equine alphaherpesviruses, but genetically, EHV-3 is significantly more divergent.

Experimental infection with equid herpesvirus 3 in seronegative and seropositive mares.

Equine coital exanthema (ECE), caused by equid herpesvirus 3 (EHV-3), has been recognized as an economically significant venereal disease for years. However, no infection models on the natural host have been established. In order to set up an experimental infection protocol, seronegative and seropositive mares were topically inoculated in the perineal region with 4 × 10(6)TCID(50)/ml of EHV-3.

Subclinical infection and periodic shedding of equid herpesvirus 3.

The temporary disruption of reproductive activities due to equine coital exanthema (ECE), caused by equid herpesvirus 3 (EHV-3), at thoroughbred breeding facilities and embryo transfer centres, has an appreciable economic impact. The aim of the present study was to estimate the prevalence of excretion of EHV-3 in mares without clinical symptoms under field conditions and the re-excretion patterns of the virus in two seropositive (presumably latently infected) mares maintained in isolation for 11 mo. The EHV-3 virus was detected in perineal-vaginal swabs by real time PCR in 14 (6%) of 220 thoroughbred mares without clinical symptoms at the time of breeding.

Experimental reactivation of equine herpesvirus-3 following corticosteroid treatment.

State of latency, well known for several herpesviruses, has been proposed for equine herpesvirus-3 (EHV-3) and supported by epidemiological observations. No detailed assessment about reactivation, patterns of excretion and reexcretion has been formally reported. An experimental reactivation study by corticosteroid treatment in previously naturally infected horses was therefore carried out.

Standardization and validation of an agar gel immunodiffusion test for the diagnosis of equine infectious anemia using a recombinant p26 antigen.

We developed and validated an agar gel immunodiffusion test (AGID) test for the diagnosis of equine infectious anemia (EIA) using as antigen the p26 protein of equine infectious anemia virus (EIAV) produced in the Escherichia coli expression system. The developed rp26-AGID test showed an excellent diagnostic relative sensitivity (100%) and specificity (100%) compared to a commercial AGID assay when 1855 field serum samples were analyzed. In addition, the rp26-AGID demonstrated to be a precise assay with excellent repeatability and reproducibility.

West Nile virus isolation from equines in Argentina, 2006.

West Nile virus (WNV) was isolated from the brains of 3 horses that died from encephalitis in February 2006. The horses were from different farms in central Argentina and had not traveled outside the country. This is the first isolation of WNV in South America.
