SOME NEW DATA ON THE MORPHOLOGY OF THE NEMATODE LAPPETASCARIS-LUTJANI RASHEED, 1965 (NEMATODA, ANISAKIDAE)

NC DE

Folia Parasitologica 37[4] 295-299 (1990)

The nematode, Lappetascaris lutjani, recovered from the fish, Pellona ditchela from West Bengal, India, was studied by light and scanning electron microscopes. Surface features of the head and tail ends of the body as also the distal parts of the spicules were described, illustrated and discussed with regard to the available data relative to this species. Present LM studies provide information concerning the head structure in greater detail and existence of narrow but distinct lateral cervical alae. SEM studies give microtopographic details of the worm. Some of these represent new information and might be useful in the taxonomic evaluation of this...

UNIQUE OCCURRENCE OF LARVAL STAGES OF AUSTRALAPATEMON SP IN CZECHOSLOVAKIA

NASINCOVA, V

Folia Parasitologica 37[4] 301-305 (1990)

Cercariae Australapatemon sp. were found in the snail Radix peregra peregra in North Bohemia (Czechoslovakia). Developmental stages obtained from the first intermediate host-daughter sporocysts and cercariae are described in detail. The penetration of cercariae into the leech Glossiphonia heteroclita was observed; further development in the second intermediate host was not studied. Until now, the larval stages of this type have been known only from Australia.

SOME ASPECTS OF THE PRESENCE OF SURFACE - ASSOCIATED ACID MUCOSUBSTANCES ON LARVAL TAENIA-SAGINATA INFECTING SUITABLE AND UNSUITABLE HOSTS

J SCHRAMLOVA, K BLAZEK, J PROKOPIC

Folia Parasitologica 37[4] 307-312 (1990)

The coat of acid mucosubstances occurring on the bladder surface was studied in Cysticercus bovis (larvae of Taenia saginata) developing in specific (cattle) and nonspecific (some other ruminants) intermediate hosts. In cysticerci developing in nonspecific intermediate hosts, this coat is absent or poorly developed even at the time when it is completely formed on the bladder surface of C. bovis from cattle. If the cysticercus develops up to the infective stage in a nonspecific intermediate host, it is usually localized outside the muscles: in the brain, lungs or liver. Its bladder is then also covered by a coat of acid mucosubstances. The absence...

PATHOMORPHOLOGICAL CHANGES IN ROE DEER LUNGS DURING ONTOGENY OF VARESTRONGYLUS-CAPREOLI (STROH ET SCHMID, 1938) DOUGHERTY, 1945

R SVARC, A PAJERSKY

Folia Parasitologica 37[4] 315-321 (1990)

The specification of pathomorphological changes occurring during Varestrongylus capreoli ontogenesis was studied on the basis of different forms of inflammation. The character, course and extent of inflammatory reactions were contingent on the maturity, localization and number of worms. The allergic inflammation accompanying the development of juvenile specimens inside the alveoli was followed by the regeneration of lung tissues providing suitable conditions for further development of the parasite. A prolonged edema occurring during the differentiation of juvenile parasites localized in the bronchioles caused a disposition of the roughen bronchial...

EVALUATION OF SETARIA-CERVI ANTIGEN IN THE DIAGNOSIS OF HUMAN FILARIASIS

AJ ALMEIDA, MK BHOPALE, DM RENAPURKAR

Folia Parasitologica 37[4] 323-329 (1990)

Bovine filariid worm (Setaria cervi) antigen was evaluated for the immunodiagnosis of human filariasis. Patients with manifestations of filarial infection; (1) microfilaremia cases, (2) chronic clinical cases, (3) tropical pulmonary eosinophilia (TPE) cases) were taken for the investigations along with (4) normal endemic and non-endemic human subjects. CIEP, IFAT and ELISA tests were employed for detection of serum antibodies. There was a high degree of sensitivity shown by IFAT (1:64-1:256) and ELISA (1:200-1:20,800) in microfilaraemia cases and higher in chronic clinical cases with IFAT (1:128-1:1,024) and ELISA (1:12,800-1:102,400). Only one...

THE ACTIVITY OF ASPERGILLUS-OCHRACEUS (FUNGI) ON REPLETE FEMALES OF RHIPICEPHALUS-SANGUINEUS (ACARI, IXODIDAE) IN NATURAL AND EXPERIMENTAL CONDITIONS

ESTRADAPENA, A GONZALEZ, J CASASOLAS, A

Folia Parasitologica 37[4] 331-336 (1990)

Aspergillus ochraceus Wilhelm was isolated from Rhipicephalus sanguineus (Latreille) ticks infected under natural conditions, and developing an illness characterized by absence of oviposition, mummification and death. From the histological sections, it is deduced that A. ochraceus colonized the ticks via the anus, as posterior gut and Malpighian tubules are invaded. The experimental inoculation was carried out on replete female ticks; a disease alike to that observed in naturally infected ticks developed only when specimens are placed under a relative humidity near saturation.

2 NEW SPECIES OF THE GENUS GYRODACTYLUS (MONOGENEA) FROM THE FINS OF LEUCISCUS-CEPHALUS (L)

R ERGENS

Folia Parasitologica 37[4] 337-339 (1990)

Gyrodactylus kearni sp. n. and G. lamberti sp. n. (Monogenea: Gyrodactylidae) are described from the fins of the freshwater fish, Leuciscus cephalus (L.) (Cyprinidae), from the Rokytna River and Stepanovicky Brook (basin of the River Danube), Czechoslovakia. G. kearni sp. n. is most related to G. leucisci Zitnan, 1964 in the shape and size or marginal hooks, but can be seperated from it in the shape of anchors and ventral bar. G. lamberti sp. n. is most closely related to G. gobii Shulman, 1953 and G. truttae Glaser, 1974 in the shape of the complex of anchors, but differs markedly from them in the shape of the hook proper of marginal hooks.

DYNAMICS OF ANTIBODY-PRODUCTION IN MICE INFECTED WITH TOXASCARIS-LEONINA LINSTOW, 1909

V FIGALLOVA, J PROKOPIC

Folia Parasitologica 37[4] 351-354 (1990)

Using counterimmunoelectrophoresis and ELISA tests the dynamics of antibody production in serum of mice experimentally infected with Toxascaris leonina was studied. The production of antibodies using both tests has already been detectable in serum of mice from 7 days post infection (DPI) and their level persisted till the end of the experiment, i.e. till 77 DPI. The most positive were reactions of sera with Antigens 1 and 3.

THE EFFECT OF AGE ON THE FERTILITY OF MALES OF CULEX-MOLESTUS (DIPTERA, CULICIDAE)

J OLEJNICEK

Folia Parasitologica 37[4] 355-357 (1990)

Older males of C. molestus have a markedly lowered fertility (even by 50%) and the image productivity of their progeny is much lower than that of freshly hatched males (more than 6 x). This fact may hinder the population explosion particularly in those species whose individual generations coincide in the course of a year or are much diffused.
