“…Na Grécia, de 289 ovelhas, criadas em sistema semi-intensivo (com menor possibilidade de contato com gatos jovens) e com histórico de aborto, 144 (49,8 %) foram positivas para T. gondii 22 . No Brasil, Gabardo et al 23 descreveram um surto de aborto em ovelhas devido ao T. gondii.…”

Toxoplasma gondii pode causar problemas reprodutivos em ovinos. Com os objetivos de determinar a soroprevalência de T. gondii e de identificar os fatores de risco da infecção, foram coletadas 1308 amostras de sangue de ovelhas em idade reprodutiva (≥ 18 meses), em 92 propriedades de 30 municípios da mesorregião serrana de Santa Catarina-Brasil, para realizar a pesquisa de anticorpos específicos por meio de reação de imunofluorescência indireta (RIFI). Informações dos animais (manejo, frequência e tipo de transtornos reprodutivos, dieta e contato com gatos) foram obtidas por meio de questionário. Os dados foram analisados pelos testes exato de Fisher e do qui-quadrado (p < 0,05). Das 1308 amostras analisadas, 55,9 % (731/1308) apresentaram anticorpos IgG anti-T. gondii, nas diluições de 1:64 a 1:4096. Não houve diferença significativa (p > 0,05) entre as propriedades ou municípios avaliados, tampouco na correlação entre os resultados de sorologia e as variáveis raça e contato com gatos. Correlação positiva (p = 0,003) foi verificada entre a soropositividade e a dieta exclusiva de pasto nativo. Tendência (p = 0,07) de maior soroprevalência entre os animais com desordens reprodutivas foi observada. A infecção por T. gondii em ovelhas está amplamente disseminada na mesorregião serrana de Santa Catarina, o que representa risco para a saúde pública.

Emergence of novelLeptospiraserovars: a need for adjusting vaccination policies for dogs?

et al. 2012

View full text Add to dashboard Cite

A total of 855 sera from dogs in Greece were tested for antibodies to strains belonging to the Pomona, Grippotyphosa and Australis serogroups of Leptospira to assess exposure levels to these serogroups, possible associations with clinical disease and to evaluate whether these findings support the inclusion of additional serovars in dog vaccines. Antibodies were detected in 110 (12·9%) dogs. The highest seroprevalence (4·9%) was to the proposed novel serovar Altodouro belonging to the Pomona serogroup. This serovar also showed a statistically significant association with clinical disease. Serovar Bratislava antibodies were found in 3·4% of sera. Consideration should be given to the inclusion of serovars belonging to the Pomona serogroup and serovar Bratislava in future dog vaccines for the Greek market.

Scientific Opinion on the public health hazards to be covered by inspection of meat from sheep and goats

A risk ranking process identified Toxoplasma gondii and pathogenic verocytotoxin-producing Escherichia coli (VTEC) as the most relevant biological hazards for meat inspection of sheep and goats. As these are not detected by traditional meat inspection, a meat safety assurance system using risk-based interventions was proposed. Further studies are required on T. gondii and pathogenic VTEC. If new information confirms these hazards as a high risk to public health from meat from sheep or goats, setting targets at carcass level should be considered. Other elements of the system are risk-categorisation of flocks/herds based on improved Food Chain Information (FCI), classification of abattoirs according to their capability to reduce faecal contamination, and use of improved process hygiene criteria. It is proposed to omit palpation and incision from post-mortem inspection in animals subjected to routine slaughter. For chemical hazards, dioxins and dioxin-like polychlorinated biphenyls were ranked as being of high potential concern. Monitoring programmes for chemical hazards should be more flexible and based on the risk of occurrence, taking into account FCI, which should be expanded to reflect the SUMMARYFollowing a request from the European Commission to the European Food Safety Authority (EFSA), the Panel on Biological Hazards (BIOHAZ) was asked to deliver a Scientific Opinion on the public health hazards to be covered by the inspection of meat from sheep and goats. The Panel was supported by the EFSA Panels on Contaminants in the Food Chain (CONTAM) and Animal Health and Welfare (AHAW) in the preparation of this Opinion. Briefly, the main risks for public health that should be addressed by meat inspection were identified and ranked; the strengths and weaknesses of the current meat inspection system were evaluated; recommendations were made for inspection methods fit for the purpose of meeting the overall objectives of meat inspection for hazards currently not covered by the meat inspection system; and recommendations for adaptations of inspection methods and/or frequencies of inspections that provide an equivalent level of protection were made. In addition, the implications for animal health and animal welfare of any changes proposed to current inspection methods were assessed.Sheep and goats were considered together, unless otherwise stated. Decision trees were developed and used for priority ranking of biological and chemical hazards present in meat from sheep and goats. For biological hazards the ranking was based on the magnitude of the human health impact, the severity of the disease in humans and the evidence supporting the role of meat from sheep and goats as a risk factor for disease in humans. The assessment was focused on the public health risks that may occur through the handling, preparation for consumption and/or consumption of meat from these species. The term 'priority' was considered more appropriate than 'risk' for categorizing the biological hazards associated with meat from small rumina...
