While the need for effective animal health surveillance is widely recognised for diseases management, most veterinary services are facing significant budget constraints. There is a real need to develop cost-effective surveillance systems. To ensure quality of these systems, there is a further need to design comprehensive, timely, effective and affordable evaluation frameworks. Depending on epidemiological, sociological and economic factors, animal diseases surveillance systems can be complex, likewise the choice of attributes to describe them and therefore the choice of methods and tools to evaluate them. Participatory approaches could provide the framework needed to tackle that complexity with sufficient flexibility. [less ▲]

In pigs the Mycobacterium avium complex (MAC) causes granulomatous lymphadenitis. Carcasses with such lesions must be detected, as parts of the affected carcasses and organs have to be condemned. These nontuberculous mycobacteria are opportunistic pathogens which have acquired an increasing importance in public health in recent decades due to their ability to cause lung diseases, lymphadenitis in children and systemic infections in immunocompromised patients ‐ even if the potential risk of infection of an immunocompromised person by MAC in the consumption of undercooked pork still has to be determined. The first objective of this study was to evaluate the prevalence of submandibular granulomatous lymphadenitis in pigs slaughtered in Belgium. Between August 2010 and September 2011, 16,211 carcasses were inspected by the same veterinarian in 2 slaughterhouses – one in Flanders, the other in Wallonia. Eighty‐six suspected cases of submandibular granulomatous lymphadenitis (0.53% of pigs; 95% Confidence Interval: 0.42‐0.65%) were identified, collected and submitted to histopathological (Ziehl‐Neelsen and haematoxylin‐eosin staining) and bacteriological (culture, PCR, molecular typing) tests. The second objective of the study was to characterize lesions and to identify the relative importance of MAC and Rhodococcus equi to explain the lesions. Mycobacterium avium subsp. hominissuis (MAH) was isolated from 6 lymph nodes (7.0%; 95% CI: 2.6‐14.6%) and Rhodococcus equi from 45 (52.3%; 95% CI: 41.3‐63.2%). The final objective of the study consisted in farm investigation to evaluate the possible source of contamination of pigs by MAH. Potential sources such as sawdust, water, wild birds and/or cattle were identified. [less ▲]

Porcine cysticercosis, which is widely distributed in Africa, causes financial losses and diseases among humans. To control the disease in an area, it is important to know the geographical distribution. In this study, spatial distribution of porcine cysticercosis in southern Benin was performed. By using the number of partial organ seizures at meat inspection, the study has revealed high risks of porcine cysticercosis in administrative districts of Aplahoue, Dogbo, Klouekanme and Lokossa. The proportion of seizures ranged from 0.06% for neck muscles to 0.69% for tongues. Spatial analysis of carcass seizure frequencies revealed Akpro Misserete, Avrankou, Dangbo, Porto-Novo, Ifangni and Aguegues as the most likely clusters (P<0.001) for porcine cysticercosis distribution. The risk factor found to be associated with the porcine distribution was the Taenia solium cysticerci positive testing using lingual examination by butchers and retailers. Catching of pig within the Zou and Mono department and pigs directly purchased by the butcher were found protective factors for distribution of porcine cysticercosis in southern Benin. [less ▲]

Serology is the most convenient method for detecting brucellosis but the efficient use of such tests in disease control requires evaluation of diagnostic performance and discriminative ability. The objective of this study was to assess the performance of the Rose Bengal test (RBT) and an indirect ELISA (iELISA) in diagnosing brucellosis in 995 serum samples collected from cattle in the Ivory Coast between 2005 and 2009. A Bayesian approach was used to evaluate the two tests by estimating their sensitivities and specificities. The correlation-adjusted sensitivity of the iELISA was estimated to be 96.1% (credibility interval [CrI], 92.7-99.8), whereas that of the RBT was 54.9% (CrI, 23.5-95.1). High correlation-adjusted specificities were found for both tests (95.0%; [CrI, 91.1-99.6] for the iELISA and 97.7%; [CrI, 95.3-99.4] for the RBT, respectively). The true prevalence of brucellosis was estimated from the serum samples to be 4.6% (95%; [CrI, 0.6-9.5]). The level of agreement between the two tests was evaluated using indices of agreement (n=995). Good agreement was found for negative results (96.6%; confidence interval [CI], 95.7-97.4), a finding supported by an estimated significant correlation of 0.37 (95%; CI, 0.01-0.73) within the sera testing negative. Agreement was lower for sera testing positive (52.2% CI: 41.9-62.5). The findings highlight the importance of using these two tests in combination as part of any brucellosis control programme.

Parafilariosis is a vector borne parasitic disease caused by the development of the nematode Parafilaria bovicola in the subcutaneous and intermuscular connective tissues of cattle. On February 28th 2012, the so-called bleeding spots were observed in two heifers and one bull in a cattle herd close to Namur (Belgium). The animals had been treated in December with an injectable ivermectin/closantel solution (Closamectin pour on®, Norbrook Lab) at the recommended dosage. Samples of serohaemorrhagic exudate and blood as well as skin biopsies were collected. Embryonated eggs of Parafilaria bovicola in the serohaemorrhagic exudate and high levels of creatine phosphokinase (CPK) were detected. Clinically affected animals were treated with injectable ivermectin (Ivomec®, Merial) at 200 µg/kg. Two epidemiological phone surveys were carried out in the south of Belgium (Wallonia) in order to estimate the geographical distribution of this condition since it was first described and published in 2009. A standardized questionnaire was used and the results were analysed. Most outbreaks were recorded in the provinces of Liege and Luxembourg. The initial source of infection is still unknown but this parasitic infection is clearly spreading from the initial Belgian outbreak site. [less ▲]

BACKGROUND: Descriptions of acid-base disturbances in atypical myopathy (AM) are limited. OBJECTIVES: Describe and compare traditional and quantitative acid-base abnormalities and cardiovascular shock status in horses with AM at admission. ANIMALS: 34 horses with AM, 15 healthy controls. METHODS: Retrospective case-control study. Records were searched for shock variables (packed cell volume [PCV], blood urea nitrogen [BUN], heart and respiratory rate) and acid-base variables (venous blood gas analysis, electrolytes, total protein, lactate) on admission. Base excess (BE) of free water (BEfw), chloride (BEcl), total protein (BEtp), and unidentified anions (BEua), anion gap (AG), measured strong ion difference (SIDm), and concentration of total nonvolatile weak acids ([Atot]) were calculated. Acid-base classifications, using simplified strong ion model and traditional approach, and shock grades were assigned. A 2-sample Wilcoxon rank-sum test and Bonferroni correction compared variables in AM cases versus control horses. Significance was P < .05/16 for acid-base and P < .05/5 for shock variables. RESULTS: Tachycardia, tachypnea, and normal to increased PCV and BUN were common in AM cases. Respiratory, metabolic acid-base alterations, or both were mainly caused by respiratory alkalosis, lactic acidosis, and SIDm alkalosis, alone or in combination. Evaluated variables (except pH, potassium concentration, total protein, and related calculations) were significantly different (P < .001) between AM cases and control horses. The strong ion model provided a more accurate assessment than the traditional approach and identified mixed derangements. CONCLUSIONS AND CLINICAL IMPORTANCE: Acid-base derangements should be evaluated in horses with AM and this preferably with the strong ion model. [less ▲]

The risk linked to furan ingestion has been assessed in previous papers for Belgian adults and children (Scholl et al., 2012b; Scholl et al., 2012c). The present paper focuses on infants consuming only ready-to-eat baby food. As there is no Belgian baby dietary database, the furan exposure assessment was carried out by using Italian infant consumption database and Belgian contamination data. The estimated daily intake (EDI) was calculated according to a deterministic methodology. It involved 42 commercially available ready-to-eat baby food and 36 baby consumption records. The mean EDI was 1,460 ng * (kgb.w.*day)-1 which is 3.8 times higher than the 381 ng * (kgb.w.*day)-1 reported for Belgian adults, and 3.5 times higher than the 419 ng * (kgb.w. * day)-1 measured for Belgian children. To assess and characterize the risk for babies exposure the Margin of Exposure (MoE) was calculated. It highlighted that 74% of infants have a MoE below 1,000, with a minimum of 140. However, these are only preliminary results as they were calculated from a very small dataset and the infant cytochrome P450 activity is significantly different compared to the adult. Therefore, the risk linked to furan ingestion by babies should be assessed in a different manner. To this end, additional data regarding a baby diet as well as a better understanding of furan toxicity for babies are needed to characterize more accurately the risk for infants. [less ▲]

In Vietnam where epidemics occur regularly in animal production, the farmers consider antibiotics as one of the solutions to fight against livestock diseases, thus the risk of abuse, even illegal use of antibiotics in livestock is very high. However, this is a recent issue and has not yet been thoroughly investigated. A cross-sectional study on the use of antibiotics in pig and poultry production as well as the farmer’s knowledge on the danger of the antibiotic use in three different animal production systems (farm household, semi-industrial and industrial) was conducted from July 2009 to March 2010 on 270 entities, in 3 representative localities of the Red River Delta (RRD). The results showed that a large volume of antibiotics was used arbitrary in all animal production systems. Animals were not only treated for acute diseases, but also for disease prevention, and for growth promotion. At least 45 antibiotics of more than 10 classes were used. Fifteen antibiotics were used in pig and poultry feed. For diseases treatment and prevention, antibiotics were used abusively and even illegally (e.g. chloramphenicol) by both farmers and veterinarians. The findings of this survey will permit developing new strategies for prudent use of antibiotics in livestock in Vietnam. These results will help not only to strengthen issues such as veterinary networks; antibiotics use guidance, residues monitoring systems and food safety, but also to improve awareness and ethics of producers and veterinary drug sellers.

Antimicrobial resistant zoonotic pathogens present on food constitute a direct risk to public health. Antimicrobial resistance genes in commensal or pathogenic strains form an indirect risk to public health, as they increase the gene pool from which pathogenic bacteria can pick up resistance traits. Food can be contaminated with antimicrobial resistant bacteria and/or antimicrobial resistance genes in several ways. A first way is the presence of antibiotic resistant bacteria on food selected by the use of antibiotics during agricultural production. A second route is the possible presence of resistance genes in bacteria that are intentionally added during the processing of food (starter cultures, probiotics, bioconserving microorganisms and bacteriophages). A last way is through cross-contamination with antimicrobial resistant bacteria during food processing. Raw food products can be consumed without having undergone prior processing or preservation and therefore hold a substantial risk for transfer of antimicrobial resistance to humans, as the eventually present resistant bacteria are not killed. As a consequence, transfer of antimicrobial resistance genes between bacteria after ingestion by humans may occur. Under minimal processing or preservation treatment conditions, sublethally damaged or stressed cells can be maintained in the food, inducing antimicrobial resistance build-up and enhancing the risk of resistance transfer. Food processes that kill bacteria in food products, decrease the risk of transmission of antimicrobial resistance. [less ▲]
