“…Moreover, most of the farms raised goats and sheep in the same herd, which could increase the rate of exchange of C. pseudotuberculosis strains between goats and sheep. These results are also supported by the high prevalence of CLA found in goat and sheep flocks in the State of Minas Gerais (Guimarães et al, 2009;Seyffert et al, 2010) and in goat flocks in the State of Ceará, which is also in the northeast region (Pinheiro et al, 2000).…”

“…C. pseudotuberculosis is the etiological agent of caseous lymphadenitis (CLA) in goats and sheep (Guimarães et al, 2011a), which is characterized by abscesses in superficial and visceral lymph nodes and is associated with significant losses in animal production (Baird and Fontaine, 2007). CLA is distributed worldwide and has a major impact in most sheep-and goat-raising areas (Baird and Fontaine, 2007;Seyffert et al, 2010, Guimarães et al, 2009, 2011a.…”

“…Nevertheless, it was lower than the result obtained by , who found that seropositivity was 82.7% in Ceará and 95.9% to 100% in Minas Gerais SEYFFERT et al, 2010). However, the results from the study reveal that a high percentage of positive properties with a high number of seropositive goats are found in each property studied.…”

Goat farming in the northeastern regions of Brazil plays an important role in the socio-economic functions of the country. However, high rates of morbidity and mortality occur in the animals, caused primarily by infectious diseases like caseous lymphadenitis, which is widespread in goat herds; this causes serious economic losses to the farming business. Although events such as animal fairs are common in the region, wherein most of the goats and sheep are sold, the risk of disease transmission remains, since the health condition of the animal is unknown. The aim of this study was to determine the frequency of anti-Corynebacterium pseudotuberculosis antibodies present in the goats sold at the animal fair of Tabira -PE, Northeastern semi-arid. Serum samples from 233 goats were collected from the period of November 2014 to June 2015. The diagnosis of infection by C. pseudotuberculosis was made using the indirect ELISA technique. The number of goats seropositive for C. pseudotuberculosis was identified as 87 (37.34%; 95% CI = 31.38 -43.71%). Of the nine flocks evaluated, five (55.55%) were positive. Thus, it is suggested that infection by C. pseudotuberculosis is widespread in the goats sold at the animal fairs in the semi-arid Northeastern, reinforcing the need for disease diagnosis in goat herds in the region for the possible implementation of disease control programs.

“…Czech Republic; Skalka et al 1998;Italy;Battini et al 2016, and Portugal;Can et al 2016). Surveys in Italy and Portugal revealed the presence of abscesses in 90% of the visited farms in both countries Can et al 2016), whereas in Brazil CLA was present in 98% of the herds (Seyffert et al 2010). The problem is therefore widespread and it may jeopardise animal welfare (Ferrante et al 2012) and cause economic losses, mainly due to reduced milk production, and to carcase damage (Fontaine & Baird 2008;Regassa et al 2013).…”

Abscesses are a common problem in goat farms worldwide. In most cases, the disease is caused by Corynebacterium pseudotuberculosis that is the aetiological agent of caseous lymphadenitis (CLA). CLA causes considerable economic losses, due to reduced milk production, and to carcase damage. At present, no effective therapy for CLA is available and vaccine use is limited. The current study presents evidence for loci associated to CLA susceptibility identified using the 50K Goat SNP panel in a case-control genome wide association study. The analysis of the genotype data identified four chromosomal regions associated with disease status: on chromosomes 5, 7, 8 and 11. These results provide the first evidence for genetic loci involved in the immunological response to CLA in goat. Knowledge of genetic variations related to susceptibility will facilitate the incorporation of this information for the improvement of health status in the goat species.ARTICLE HISTORY
