    During July and August 1985, a field survey on the lung fluke was carried out at six localities in the peninsular Malaysia. A total of 1, 009 freshwater crabs belonging to eight species were examined and Paragonimus westermani metacercariae were found in four species of the crabs, Parathelphusa maculata from Kuala Pilah and Ulu Langat, Parathelphusa malaysiana, Johora tahanensis and Irmengardia pilosimana from Sungai Wa. The three species of crabs except Parathelphusa maculata are recorded as new crustacean hosts of P. westermani. Parathelphusa maculata harboured more than 60% of the total metacercariae in the muscle, 20-25% in the gills and about 10% in the liver, but no metacercariae were found in the heart. In contrast, a substantial number of metacercariae parasitized the heart of the crab, Parathelphusa malaysiana.

    Isolation frequency of enteropathogens from diarrheal stools was examined in Surabaya, Indonesia. A total of 385 patients with diarrhea including 264 children under 2 years of age and 121 adults were enrolled. Bacterial enteropathogens other than Campylobacter jejuni were positive in 164 cases out of 385 (44%), while C. jejuni was isolated from 13 cases out of 173 examined (7.5%). Rotavirus was detected in 91 cases of 184 examined (49%), and 34 cases of these 91 were coinfected with bacterial pathogens. Diarrheagenic Escherichia coli, which were isolated from about 30% of all 385 patients, were highly resistant to ampicillin and tetracycline. Vibrio cholerae O1 was isolated in 17 of 121 adult diarrhea cases.

    Qualitative analysis of antibody response before and 12 months after treatment of human strongyloidiasis was performed to identify the antigenic component which may be useful for serological evaluation of the effectiveness of postchemotherapy. The immunoblotting patterns changed significantly after successful treatment in almost all patients; some responses decreased in their intensity and some disappeared. Whereas, the patterns of reactivity after treatment could not be distinguished from those before treatment in patients who were interpreted to be equivocal for complete cure because their antibody levels did not show a significant decrease after treatment. The immunoblotting patterns, however, varied considerably for each patient and it was difficult to identify the antigenic component which may be effective to detect reduced antibody responses early after treatment.

    A Japanese woman, 39, in Oita, Japan who showed a “coin lesion” in the lung on a routine X-ray examination, though asymptomatic, was diagnosed as a pulmonary dirofilariasis due to Dirofilaria immitis by the morphological characteristics of cross-sectioned worm specimens in the resected tissue. Some comments on an internal longitudinal ridge of the worm's cuticle, one of key characters for identification of the genus Dirofilaria, were given.
