The digestive tract of a fully formed free-swimming cercaria of Echinostoma revolutum (Froelich, 1802) Dietz, 1909 was studied by electron microscopy. The oral sucker and pharynx are covered by a tegument. The oesophagus and the caeca are not luminized. They are packed with giant epithelial cells with electron-dense granules of irregular shape, rough endoplasmic reticulum and its cisterns, and Golgi apparatus. The tegument of the oral sucker cavity contains numerous uniciliate receptors.

In 1989, samples of some freshwater fishes collected in Vientiane Province (R. Mekong basin) in Laos were examined for helminths. This material comprised 11 species of parasitic nematodes (7 adults and 4 larvae), including 3 species new to science: Camallanus (Camallanus) hampalae sp. n. from Hampala macrolepidota, Procamallanus (Punctocamallanus) punctatus sp. n. from Mystus rhegma and Mystus sp., and Rhabdochona (Globochona) equispiculata sp. n. from Hampala macrolepidota and H. dispar. Zeylanema Yeh, 1960 is considered a subgenus of the genus Camallanus, Dentocamallanus subgen. n. (type species C. (D.) sweeti (Moorthy, 1937)) is proposed for the species of Paracamallanus with teeth in the buccal capsule, and Punctocamallanus subgen. n. (type species P. (P.) punctatus sp. n.) for the species of Procamallanus with the buccal capsule ornamented with punctations. The name Rhabdochona wangi nom. nov. is proposed for R. bagarii Wang et Guo, 1983 (a homonym to R. bagarii Gupta et Srivastava, 1982) and Camallanus gomtii Gupta et Verma, 1978 is newly synonymized with Neocamallanus ophiocephali (Pearse, 1933). All the nematodes are recorded from Laos for the first time. The parasites are briefly described and illustrated and some problems concerning their taxonomy and geographical distribution are discussed.

A reexamination of the type specimens of Thominx platyrrhinorum Barus, 1961, described from the small intestine of the monkey Cebus capucinus from a zoo in Czechoslovakia, has revealed that it belongs to the genus Aonchotheca López-Neyra, 1947. The minute refractile formations on the surface of the proximal part of the spicular sheath, originally described as spines in this species, are also present in Aonchotheca annulosa parasitizing murid rodents. Since there are no substantial morphological or biometrical differences between these two species, as indicated by the description of A. annulosa specimens originating from Apodemus sp. from Czechoslovakia, T. platyrrhinorum is considered to be a synonym of A. annulosa (Dujardin, 1845). Another synonym of the latter is the species originally described as Thominx sadovskoi (sic) (= sadovskajae) Morozov in Skryabin et al. 1957. Armocapillaria Gagarin et Nazarova, 1966, earlier considered a synonym of Pterothominx Freitas, 1959, is now reerected as a subgenus of Aonchotheca López-Neyra, 1947. Armocapillaria moschiferi and Capillaria brochieri are transferred to Aonchotheca as A. (A.) moschiferi (Gagarin et Nazarova, 1966) comb. n. and A. (A.) brochieri (Justine, 1988) comb. n.
The life cycle of E. bolschewense, the species with 37 collar spines and closely related to E. revolutum, was experimentally studied. The following developmental stages are described: mother and daughter rediae, cercaria, metacercaria, and adult. The freshwater prosobranchiate snail Viviparus contectus was found to be the first intermediate host in nature. Under experimental conditions, the miracidia developed in V. contectus. They did not, however, penetrate into Bithynia tentaculata or into any of the pulmonate snails tested. The cercariae encysted in various Prosobranchia and Pulmonata. Adult worms were commonly obtained from hamsters (Mesocricetus auratus) and only exceptionally from chickens (Gallus gallus f. dom.). The species studied is considered to be conspecific with Cercaria bolschewensis described by Kotova (1939).

The development of the tapeworm Khawia sinensis parasitizing carp (Cyprinus carpio L.) has been studied from the release of cestode eggs into water to the formation of infective procercoids in the intermediate host under laboratory conditions. The rate of embryonal development is greatly influenced by the water temperature. While at 5 degrees C the development of oncospheres was not recorded, at 10-12 degrees C, 15 degrees C, 20-22 degrees C, and 23-24 degrees C oncospheres were fully formed after 57, 42, 21 and 16 days, respectively. Infectivity of oncospheres was confirmed by successful experimental infection of the intermediate hosts: Tubifex tubifex and Limnodrilus udekemiamus (Oligochaeta: Tubificidae). Fully formed procercoids infective for the definitive host were found in the intermediate host from 52 days of development at 20-22 degrees C. From the third week of development in the intermediate host, most of the parasite larvae were located in the anterior part of the tubificid body, mainly between 8th and 15th segments.
