Peste des petits ruminants (PPR) is a highly contagious viral disease that mainly affects goats and sheep in Asia, Africa and the Middle East, and threatens Europe [R.E.1]. The disease is endemic on the African continent, particularly in West Africa, and is a major factor driving food insecurity in low-income populations. The aim of this research study was to carry out surveillance, genetic characterisation and isolation of recently circulating PPR viruses (PPRV) in sheep and goats from the six agro-ecological zones of Nigeria. A total of 268 post-mortem tissue samples of lung and mesenteric ganglia were collected from clinically suspected sheep and goats in 18 different states, of which five never previously sampled. The presence of PPRV was confirmed using a reverse-transcription coupled with a polymerase chain reaction (RT-PCR) assay. A total of 72 samples, 17 sheep (6%) and 55 goats (21%), were found to be PPR positive. Positive samples were distributed in almost all states, except Kano, where PPR was detected in previous studies. The PPRV-positive samples were further confirmed by sequencing or virus isolation in areas where the infection had never previously been detected. These results confirm the active circulation of PPRV across all six agro-ecological zones of Nigeria, and consequently, the need for introducing strict measures for the control and prevention of the disease in the country.

The article reviews the outbreaks and distribution of African swine fever (ASF) in South Africa since the first probable outbreak that occurred in the Koedoesrand Ward in 1926. Retrospective data on the ASF outbreaks in South Africa were obtained from the World Organisation for Animal Health (OIE) disease database and the South African veterinary services annual reports in addition to published articles and online sources. South Africa has experienced many outbreaks that can be divided into 2 time periods: the period before the development of the OIE diseases database (1993) and the period after. More than 141 outbreaks of ASF were reported during the first period. Since the development of OIE disease database, 72 outbreaks directly involving 2968 cases, 2187 dead and 2358 killed pigs mainly in smallholder pig farms were reported. The median number of cases for a given ASF outbreak is 17, but in 50% of outbreaks no pigs were killed for prevention. The most important ASF outbreak was reported in April 2014 in the Greater Zeerust district (North West province) involving 326 cases and 1462 killed pigs. However, the outbreak with highest mortality involving 250 pigs was reported in 2016 (Free State province). According to phylogenetic analysis, nine p72 genotypes (I, III, IV, VII, VIII, XIX, XX, XXI and XXII) have been identified in South Africa. Season-wise, more outbreaks were recorded during summer. It was also observed that the OIE disease database could contain errors that would have been introduced through compiled forms at country level. Spatiotemporal studies on ASF outbreaks in South Africa are therefore required in order to assess statistically and quantitatively the clustering of outbreaks over space and time.

International audience | OBJECTIVE To compare progesterone (P4) concentrations measured with surface plasmon field-enhanced fluorescence spectroscopy (SPFS) and chemiluminescence immunoassay (CLIA) in serum and plasma samples of client-owned bitches of various ages and breeds and to determine reference ranges for P4 concentrations at various stages of the estrous cycle. SAMPLES 102 serum samples and 104 plasma samples. PROCEDURES In experiment 1, 1 aliquot each of serum and plasma was analyzed for P4 concentration by use of SPFS incorporated in a veterinary-specific point-of-care immunologic analyzer and CLIA. In experiment 2, serum collected from bitches in various stages of the estrous cycle was analyzed for P4 concentration by use of SPFS to establish reference ranges for each stage. RESULTS In experiment 1, P4 concentrations measured by SPFS and CLIA were highly correlated (serum, r = 0.966; plasma, r = 0.968). In experiment 2, ranges of serum basal (proestrous) P4 concentrations (n = 114) and P4 concentrations at the estimated time of ovulation (76), during pregnancy or diestrus (107), and during the prepartum period (50) measured with SPFS were 0.42 to 1.46 ng/mL, 3.69 to 7.85 ng/mL, 11.73 to 28.24 ng/mL, and 1.54 to 3.22 ng/mL, respectively. CONCLUSIONS AND CLINICAL RELEVANCE Because serum and plasma P4 concentrations measured with SPFS were highly correlated with those measured with CLIA and ranges of serum P4 concentrations measured with SPFS for each of phase of the estrous cycle were well-defined for the large sample size, veterinarians may be able to accurately use this veterinary-specific point-of-care immunologic analyzer with SPFS methodology to determine P4 concentrations of bitches in their daily practice.

Corrigendum to “Personality in young horses and ponies evaluated during breeding shows: Phenotypic link with jumping competition results” Journal of Veterinary Behavior 44 (2021) 1–11/ JVEB_2018_190 paru dans Journal of Veterinary Behavior Volume 66, August 2023, Page 35 DOI:10.1016/j.jveb.2023.06.011 WOS:001068066200001 | International audience | Animal personality, the result of temperament being modulated by life events, is an important factor to be considered when breeding and using domestic horses. In the breeding of sport horses, personality appears as a secondary trait in selection objectives after competition performance. Moreover, the per-sonality trait of fearfulness may be viewed as a risk factor for riders. This study aimed to estimate the variability of personality characteristics measured during breeding shows and their phenotypic correla-tion with performance in jumping competitions. Data for personality characteristics were recorded during 67 breeding shows in France on 876 jumping horses, 424 jumping ponies and 45 leisure ponies aged 2 or 3 years. Their behavior was assessed during 1) customary rounds (CR) of breeding shows (conforma-tion, free jumping and height measurement at withers) and 2) specific tests (ST) conducted in-hand that measured fearfulness (novel object, novel surface and suddenness tests) and tactile sensitivity. Not all the animals were evaluated on all the behavior tests. Jumping performances from 4 to 7 years old were recorded for 724 of the horses and for 313 of the ponies in official competitions specific for horses or ponies. Environmental effects were estimated using general linear model taking into account breeding show, age and sex. The breeding show effect was significant on 23 out of 28 characteristics. Age and sex influenced approximately one third of the characteristics: younger animals were more fearful; males moved and whinnied more; geldings appeared slightly more fearful during ST. Jumping performances were mostly independent of personality characteristics. In horses, performances were phenotypically pos-itively linked with 3 characteristics during jumping CR (whinnies ( P = 0.05), main gait when entering ( P = 0.02), evasive behaviors ( P = 0.03)) and with posture during conformation evaluation CR ( P = 0.04). In ponies, jumping performances were phenotypically positively linked only with whinnies: during CR of height measurement ( P = 0.02) and during all ST ( P = 0.01). As no main fear variables were significantly related to jumping performances in the two studied populations, it seems that less fearful horses and ponies may perform well in show jumping.
