“…The animal‐level prevalence of MAP infection was 12.9%, similar to the rates reported in other studies worldwide (Nielsen and Toft ; Vilar et al. ). Animal‐level prevalence is often a key issue when policy makers determine whether an infection should be considered important or not and decide which measures to apply.…”

This study was designed to examine (i) the seroprevalence of Mycobacterium avium subs paratuberculosis (MAP) in a high-producing dairy herd with clinical symptoms of bovine paratuberculosis, (ii) MAP seroconversion and seronegativation dynamics in the herd and (iii) possible relationships between MAP infection status and herd reproductive performance. One single blood test per cow was performed early post-partum on a monthly basis from day 10-40 post-partum during the first year of the study in 519 cows belonging to a commercial dairy herd. A subset of 111 cows that became pregnant during the study was tested again 60-200 days later during the early foetal period, immediately after the first confirmation of gestation at 58-64 days post-AI. Logistic regression analysis indicated no effect of any independent variable on MAP seropositivity and conception rate 28-34 days post-AI. MAP seropositivity was not a factor affecting the anoestrous, subfertility and early foetal loss rates. In the subset of 111 cows, animals that seroconverted had a 3.9 times greater risk of suffering from early foetal loss (30.3%, 10/33) than the remaining pregnant animals (10.3%, 8/78), (95% confidence interval: 1.11-13.4; p = 0.003). In conclusion, early foetal loss was positively correlated with seroconversion to MAP. Reproductive performance was not impaired by MAP infection.

“…Yamasaki et al (2013) demonstrou que a paratuberculose está presente em 11 estados brasileiros, distribuídos nas cinco regiões do país, principalmente em rebanhos bovinos leiteiros. Na Paraíba, foi realizado um estudo da prevalência da paratuberculose nas mesorregiões do estado, em 480 rebanhos sendo encontrada uma prevalência de 34,5% entre os rebanhos e de 10,7% entre os 2504 animais amostrados (Vilar et al 2015).…”

RESUMO: Os problemas digestivos são importantes causas de afecções em bovinos e estudos sobre a frequência de ocorrência destas na região semiárida do Brasil ainda não foram realizados. Objetivou-se com este trabalho obter informações sobre a ocorrência de doenças do sistema digestório em bovinos atendidos no Hospital Veterinário da Universidade Federal de Campina Grande no período de janeiro de 2000 a dezembro de 2014. No período do levantamento foram atendidos 1.202 bovinos, sendo 19,4% (233/1202) diagnosticados com enfermidades do sistema digestório. A taxa de letalidade das enfermidades foi 49,8% (116/233). As reticulites traumáticas e a indigestão vagal foram diagnosticadas, respectivamente, em 13,3%e 5,1% dos animais atendidos, sendo considerados distúrbios motores frequentes e de alta letalidade devido à gravidade das lesões, demora no atendimento clínico e imprecisão no diagnóstico. A obstrução ao fluxo da ingesta foi também uma condição identificada frequentemente, sendo ocasionada por obstruções esofágicas (4,3%), impactações no rúmen (11,7%), omaso e/ou abomaso (3,4%) e principalmente acidentes intestinais (26,2%), tendo a totalidade dos casos superado os distúrbios fermentativos da cavidade ruminorreticular. Actinobacilose (6,9%), actinomicose (3%) e paratuberculose (1,7%) foram as doenças infecciosas bacterianas diagnosticadas. As doenças infecciosas virais diagnosticadas foram a febre catarral maligna (4,3%), diarreia viral bovina e a doença das mucosas (3%). As doenças parasitárias foram também importantes causas de morbidade em bovinos jovens (9,4%) apesar dos sistemas de criação com baixa lotação e as condições climáticas da região não favorecerem a sobrevivência de parasitos gastrintestinais, demonstrando que não estão sendo implantadas medidas de controle adequadas para estas enfermidades. Os distúrbios motores da cavidade ruminorreticular, seguido das obstruções intestinais e das doenças infecciosas digestivas são os mais frequentes problemas digestivos de bovinos na região semiárida do Brasil. A ingestão de corpos estranhos é um dos mais graves problemas na região sendo necessário intenso trabalho de divulgação sobre medidas profiláticas. Além disso, medidas de controle e profilaxia de enfermidades infectocontagiosas como a diarreia viral bovina e a paratuberculose precisam ser divulgadas, pela possibilidade de disseminação destas nos rebanhos da região.

“…In other areas of Iran, the MAP infection rate in cattle was 3.6-25% by ELISA, PCR, culture and Ziehl-Neelsen staining methods which sera, milk, and feces were used [21,[23][24][25][26][27][28]. The prevalence of MAP infection in cattle from other countries has been reported to be 2.31 to 70.4% [37][38][39][40][41][42][43][44][45][46]. The MAP infection rate in goats from some area of Iran was 37% and 17.3% by PCR and culture methods, respectively [32] but it was 0.3-45.1% in other countris [47][48][49][50][51][52][53][54][55][56].…”

Background: Paratuberculosis or Johne's disease, caused by Mycobacterium avium subsp. paratuberculosis (MAP), is chronic infectious granulomatous enteritis of ruminants, which has a worldwide occurrence. The most common symptoms of this disease in cattle are loss of milk production, weight loss, and diarrhea and in sheep and goats are emaciation, anorexia and sever disability. The aim of this study was to compare the seroprevalence of MAP in cattle, sheep and goats following the detection of clinical cases in Southwest of Iran. Blood samples were randomly collected from 530 cattle, 568 sheep and 368 goats in Southwest of Iran. Sera were tested by a commercial ELISA kit for detection of antibodies to MAP. Results: Overall apparent and true seroprevalence rate of MAP was 6% (95% CI: 4.9 – 7.3 percent) and 11.36% (95% CI: 9.87 – 13.07 percent), respectively. Apparent and true seroprevalence of MAP were 4.34% (95% CI: 2.88 – 6.46 percent) and 7.59% (95% CI: 5.61 – 10.19 percent), respectively in cattle, 6.87% (95% CI: 5.05 – 9.27 percent) and 13.34% (95% CI: 10.78 – 16.4 percent), respectively in sheep, and 7.07 %( 95% CI: 4.82 – 10.18 percent) and 13.68% (95% CI: 10.52 – 17.58 percent), respectively in goats. As a result, there was no significant relationship between species and MAP infection. Moreover, multivariate logistic regression showed that the infection rate is not associated with age, gender, and geographical location in cattle, sheep and goats (P>0.05). Conclusions: This study confirms that the seroprevalence of MAP following the detection of clinical cases is considerable in the cattle, sheep and goats in Southwest of Iran, although in cattle it is less than goats and sheep. Therefore, preventive and control measures should be considered by animal health authorities and meat and dairy processing units.
