Amino acid residues 101 to 180 of hepatitis B surface antigen (HBsAg) were predicted by sequencing the corresponding part S gene virus (HBV) DNA in 46 HBsAg-positive sera, which had been subtyped immunodiffusion with respect d/y, w/r, w1 w4 and q. The sequences nine different HBV serotypes defined these specificities found be homogeneous proving that they represent consistent variations at genomic level. Residue 127 was important as Pro, Thr Leu for w1/w2, w3 w4, respectively. Five differ...
Equine piroplasmosis is a worldwide tick-borne disease caused by the parasites Theileria equi sensu lato and Babesia caballi, with significant economic sanitary consequences. These two are genetically variable, potential impact on diagnostic accuracy. Our study aimed to evaluate frequency of asymptomatic carriers these in France describe circulating genotypes. We developed species-specific nested PCR protocol targeting 18S small sub-unit (SSU) rRNA gene used it blood samples collected from...
A total of 752 horses were involved in the CES Valencia Spring Tour 2021. Due to an equine herpesvirus-1 (EHV-1) outbreak, competition was cancelled and site locked down. The objective this study describe epidemiological, clinical, diagnostic, outcome data 160 remaining Valencia. Clinical quantitative polymerase chain reaction (qPCR) analysed for 60 a retrospective case-control observational study. risk developing clinical manifestations explored using logistic regression approach.

Abstract Background Fungi are ubiquitous in horses' environment. Their contribution to the pathophysiology of severe asthma (SA) is acknowledged, while controversies remain for mild–moderate (MA). Objectives We hypothesised that fungi a risk factor asthma. Our objective was compare different combinations analytical methods (cytology, culture) and sampling sites (tracheal wash (TW), bronchoalveolar lavage fluid (BALF)) relation clinical status (control, MA, SA). Study design Prospective...
Background Multiple cytological patterns occur in bronchoalveolar lavage fluid (BALF) of horses with inflammatory airway disease (IAD). Only few data on BALF cytokine profiles are available for IAD, and limited to mRNA expression. Hypothesis/Objective Cytological IAD associated different immunological pathways. To investigate concentrations a large number neutrophilic . Animals One hundred thirty‐eight client‐owned Standardbred racehorses active training. Methods Prospective observational...
Summary The purpose of this study was to examine the relationship between V 4 (velocity which results in a blood lactate concentration mmol/1), age and racing performance Standardbred trotters establish normal values select good poor performers. specific influence (RT) training (T1 T2) tracks also examined. A total 159 horses were divided into 5 age‐groups from 2 6 over performed 330 standardised exercise tests 3 steps at increasing speeds. velocity measured with tachometer on sulky. Blood...
The relationships between V 4 (the velocity for a blood lactate concentration of mmol/litre) and 200 heart rate bpm) the performance indices 223 healthy French trotters were analysed. They divided into four age groups three, four, five six years over, three (good, intermediate poor performers) defined by index trot (ITR), an annual calculated national stud. assessed during three‐step standardised field exercise test, indexes (ITR, earnings, best time number starts) each group. An analysis...
The Réseau d'Epidémio-Surveillance en Pathologie Equine (RESPE, the French epidemiological network for equine diseases) is a epidemio-surveillance of major diseases based around sentry veterinarians in France.The aim this study was to evaluate contribution RESPE efficient surveillance influenza virus (EIV) France.Retrospective cross-sectional study.From November 2005 October 2010, and phylogenetic studies were performed on 1426 nasopharyngeal swabs received at Frank Duncombe Laboratory....
Intestinal strongyles are the most problematic endoparasites of equids as a result their wide distribution and spread resistant isolates throughout world. While abundant literature can be found on extent anthelmintic resistance across continents, empirical knowledge about associated risk factors is missing. This study brought together results from efficacy testing factor analysis to provide evidence-based guidelines in field. It involved 688 horses 39 French horse farms riding schools both...
Summary Some basic stride characteristics of race trotters were measured by means an accelerometric device during a locomotor test in order to find parameters, predictive for performance. Twenty‐four horses various racing abilities tested on the same flat racetrack. They allocated 3 groups according their performance indices. The consisted stages at increasing speeds and third stage was performed maximum individual speed. Basic variables extracted from acceleration data using specific...
To the Editor.— Human parvovirus is already known to be responsible for aplastic crisis in chronic hemolytic anemia,1 erythema infectiosum or fifth disease,2 and arthropathies,3,4 it has recently been isolated from serum of patients with vascular purpura.5 We report case Henoch-Schonlein purpura associated human infection. H. T., a 6-year-old girl, without any significant past history, was admitted on March 8, 1985, joint pain swelling (wrists, knees, ankles) intense abdominal pain.
Summary Reasons for performing study: Dorsal displacement of the soft palate (DDSP) is one most common obstructive conditions upper respiratory tract in racehorse. This condition has a complex aetiology which may be caused or exacerbated by pharyngeal inflammation. Additionally, lower airway diseases associated with DDSP thereby contributing to exercise intolerance these horses. Objective: The aim this study was measure physiological variables during standardised test and assess prevalence...
Abstract Equine piroplasmosis is a worldwide tick-borne disease caused by the protozoan parasites Theileria equi and Babesia caballi , with significant economic sanitary consequences. It can also limit export of infected horses to piroplasmosis-free countries. These two are genetically variable, greater diversity observed in T. . This variability potentially impact diagnostic accuracy. Our study aimed evaluate frequency asymptomatic carriers these France describe circulating genotypes. We...
Summary Standardised exercise tests were performed at 2 different tracks and on an uninclined treadmill during the same week to determine influence of surface measured variables such as heart rate (HR), blood lactate concentration, packed cell volume, stride frequency, length, gait symmetry regularity derived physiological speed a HR 200 beats/min (V ), concentration 4 mmol/l maximal (VHR max ). Five French Trotters, age 3 years, in training for months prior test, track (Test 1) , racetrack...
Summary There are a variety of reasons for poor performance in racehorses. Exercise intolerance has often been associated with subclinical respiratory abnormalities, and diagnostic aids therefore used to enhance clinical detection. Physiological variables can also be measured order evaluate the metabolic reponse exercise. This study evaluated relationship between physiological measurements upper airway videoendoscopy during standardised treadmill exercise test bronchoalveolar lavage (BAL)...
Summary We hypothesised that the derived physiological variables V 2 and 4 (velocity to achieve a blood lactate concentration of mmol/l, respectively), HR (the corresponding heart rate) 200 velocity for rate beats/min) would improve with training state age, in French Trotters. A total 194 Trotters from one establishment were followed 6 years 1105 standardised field exercise tests performed on sand track. The horses divided into age groups (from 1 ≥ years) (beginning, endurance training,...
The atlanto-occipital site (AO) is convenient for retrieving an adequate volume and quality of cerebrospinal fluid (CSF) in the diagnosis neurological disease horses. However, general anaesthesia not always possible horses displaying severe signs, or economical reasons. objectives present work were to determine feasibility safety ultrasound-guided CSF puncture at AO on standing horse. Seven (six healthy one mildly ataxic) sedated with acepromazine (0.02 mg/kg bodyweight intravenously 0.04...
