ABSTRACT
Cochlosoma sp. infection was identified in a single case among 60 stunted diarrheic native turkey poults, Meleagris galopavo. A large number of the flagellated parasites was found free or within the intervillous spaces of the jejunum, ileum and cecum. Moderate enteritis was associated with the parasites. In TEM studies of the parasagittal sections of the parasite, a prominent ventral sucker like disc and flagella emerging from an opening on the ventrodorsal surface of the pyriform uninuclear parasite were found. The morphological characteristics of this protozoan match with those described for Cochlosoma anatis. The parasite could be considered as an intestinal pathogenic protozoan causing stunting and diarrhea in turkeys in Iran.

A 27-year-old Thai man presented with chronic watery diarrhea for 2 years. The diagnosis of capillariasis was made by enteroscopy after negative repeated stool tests. Here, the authors reported the first case of abnormal endoscopic finding of intestinal capillariasis. It showed segmental erythematous and swelling of proximal jejunal mucosa with an area of superficial erosion covered by exudates. The parasitic eggs were identified in jejunal content and worms were identified in jejunal mucosa. He was successfully treated with albendazole.

The effects of high and low-protein diets on the structure of the jejunal mucosa were studied in Schistosoma mansoni infected mice (morphology and histomorphometry). Weaning male albino mice were infected with 80 cercariae, fed with high (20 percent) or low-protein (5 percent) diets and compared to uninfected controls under the same conditions. Mice were sacrificed 12 weeks after infection. Animals submitted to a low-protein diet showed lower weight curves, mainly when infected. In the jejunal mucosa, finger-like villi were the predominant pattern among uninfected high-protein fed animals, while the infected ones showed leaf-shaped and flattened villi in most cases. Undernourished infected mice had 65.7 percent leaf-shaped villi. A significant increase in the number of goblet cells was seen in infected mice. A decrease in the number of absorptive cells was detected in undernourished mice, particularly in infected ones

Con objeto de estudiar la probable influencia de la Giardiasis en la actividad de la lactosa intestinal, se efectuó el estudio de la curva de tolerancia a la lactosa, en 54 personas portadoras de este parásito, comparándose los métodos, con un grupo control de 28 personas, libres de parasitosis. Se demostró, en el primer grupo, es decir, el portador de giardiasis, cursaron curvas planas de lactosa en 49 casos (90.8% de 54), mientras que el grupo control, este tipo de curva se detectó en 16 personas (57.2% de 28). Estos hallazgos se pudieron correlacionar con la clínica, ya que en el grupo parasitario, solo 4 de ellos (7.5% de 54, toleraban clínicamente la leche. Se considera que la diferencia hallada entre los dos grupos puede ser significativa en la influencia que pudiera tener la guiardiasis en los cuadros de intolerancia a la leche, como una causa secundaria y/u ontogenética.
