An Outbreak of Intestinal Obstruction by Ascaridia Galli in Broilers in Minas Gerais

Industrial broilers raised on helminthic medication-free feed were diagnosed with a severe disease caused by Ascaridia galli, characterized by intestinal hemorrhage and obstruction. A. galli was identified based on the morphological features of the nematode. Broilers were raised for a longer period (63 days) for weight recovery, grouped as stunted (n=500), had low body score and had fetid diarrhea. The duodenum-jejunum segment was the most severely affected with obstruction and had localized accumulation of gas. The intestinal mucosa was severely congested with petechial and suffusive hemorrhages. The outbreak resulted in morbidity of about 10% and mortality of up to 4% and was associated to the absence of preventive medication on feed and slack biosecurity. The reemergence of A. galli is discussed in view of the alternative poultry management and raising conditions for drug free and welfare.(AU)

Estudo da variação mensal na contaminação do solo por ovos de Toxocarasp. (Nematoda, Ascaroidea), na zona urbana do município de Londrina, Estado do Paraná, Brasil / Study of monthly variation in soil contamination by Toxocarasp eggs. (Nematoda, Ascaroidea), in the urban area of ​​the city of Londrina, State of Paraná, Brazil

Estudou-se a variação mensal na presença de ovos de Toxocara sp. no solo de 10 praças públicas da zona urbana do município de Londrina, Paraná, durante o período compreendido entre fevereiro de 1975 e maio de 1976. Em todas as amostras examinadas encontraram-se ovos de Toxaca·ra sp.; contudo, apenas em determinados períodos, durante os meses de maio-junho e setembro a dezembro de 1975 e no mês de maio de 1976, os ovos isolados apresentaram-se viáveis, revelando tendência cíclica. Discute-se a importãncia do achado e procura-se relacioná-lo com o fenômeno do cio nas cadelas (AU).
