THE DIFFERENTIATION BETWEEN FRESH-WATER AND MARINE FISH TRYPANOSOMES BY LECTIN AGGLUTINABILITY

ZAJICEK P, LUKES J

Folia Parasitologica 39[3] 195-200 (1992)

The agglutinability of three fish trypanosomes, Trypanosoma boissoni and T. triglae senegalensis from marine fish, and T. carassii from freshwater fish was compared. The tests were performed with trypomastigotes and epimastigotes in the exponential and stationary growth phases. The simple agglutination test, performed in microwell plates, used ten purified lectins, and revealed a clear difference between marine and freshwater strains when compared for their agglutinability with the HPA lectin. Whereas the cells of T. boissoni and T. triglae senegalensis became strongly agglutinated by this lectin, those of T. carassii remained unagglutinated in the...

REDESCRIPTION OF GYRODACTYLUS-TRUTTAE GLASER, 1974 (MONOGENEA, GYRODACTYLIDAE) FROM SALMO/TRUTTA M-FARIO L (CLUPEIFORMES, SALMONIDAE)

ERGENS R

Folia Parasitologica 39[3] 201-206 (1992)

On the basis of a re-examination of the type material Gyrodactylus truttae Glaser, 1974 from Salmo trutta morpha fario L. is redescribed and, at the same time, the view of Malmberg and Malmberg (1987) and Malmberg (1987, 1989) is confirmed to show that the original description of this species includes two different species. The problematic specimens of G. truttae sensu Ergens 1983 were found to be conspecific with G. truttae. On the basis of the shape and size of the marginal hook proper, the species illustrated by Glaser (1974, Fig. 6b) cannot be identified as G. derjavini Mikailov, 1975.

HISTOCHEMISTRY OF THE RACEMOSE FORM OF CYSTICERCUS-CELLULOSAE

VALKOUNOVA J, ZDARSKA Z, SLAIS J

Folia Parasitologica 39[3] 207-226 (1992)

The racemose form of brain cysticercosis arises from an intense proliferation of the bladder wall after the scolex part has degenerated. The proliferating zones are 2-3 times thicker than the remaining parts of the bladder and are characterized by a densely folded tegument and thick subtegumental and parenchymal layers. The tegument and subtegumental cells contain a large amount of acid mucosubstances with sulpho groups and hydrophilic lipids. and exhibit a high activity of alkaline and acid phosphatases. The parenchyma contains a large amount of glycogen. With the gradual aging of the bladder wall and with the first signs of autolysis, the enzymatic...

PHILOMETRA-ROBUSTA SP-N (NEMATODA, PHILOMETRIDAE) FROM THE ABDOMINAL-CAVITY OF THE SCRIBBLED TOADFISH, AROTHRON-MAPPA (LESSON) FROM THE PHILIPPINES

MORAVEC F, MOLLER H, HEEGER T

Folia Parasitologica 39[3] 227-234 (1992)

A new nematode species, Philometra robusta sp. n., is described from the female specimens collected from the abdominal cavity of the scribbled toadfish, Arothron mappa (Lesson) (Tetraodontidae, Tetraodontiformes), from coastal waters of Tawi-Tawi, Philippines. It is characterized mainly by its markedly large body (body length 275-450 mm, width 8-10 mm), arrangement and number of small cephalic papillae (eight papillae in outer circle and four in inner one), structure and length (2.4 2.6 mm) of the oesophagus, short ovaries, and presence of a pair of small subventral papilla-like projections on the ventrally curved caudal extremity. P. robusta is the...

ACANTHOCEPHALANS FROM SOME AQUATIC BIRDS FROM THE BULGARIAN BLACK-SEA COAST

DIMITROVA Z, GENOV T

Folia Parasitologica 39[3] 235-247 (1992)

A total of 371 birds from 53 species of the orders Podicipediformes, Ciconiiformes, Anseriformes, Gruiformes, Charadriiformes and Coraciiformes from the Bulgarian Black Sea coast were studied for helminth parasites. Acanthocephalans were found in 9 species: Mediorhynchus papillosus and Prosthorhynchus genitopapillatus in Tringa erythropus (new host records), Acanthocephalus lucii in Alcedo atthis (accidentally), Sphaerirostris sp. in Charadrius dubius, Filicollis anatis in Anas clypeata, A. querquedula, Fulica atra, Gallinula chloropus and Calidris ferruguinea, and Polymorphus magnus in Anas platyrhynchos and A. clypeata. The species are described...

GEOGRAPHICAL-DISTRIBUTION AND HOST SPECIFICITY OF ECTOPARASITES OF AUSTRALIAN BREAM, ACANTHOPAGRUS SPP (SPARIDAE)

BYRNES T, ROHDE K

Folia Parasitologica 39[3] 249-264 (1992)

The geographical distribution and host specificity of ectoparasites of Australian bream, Acanthopagrus australis (Gunther), A. butcheri (Munro), A. berda (Forskal) and A. latus (Houttuyn) are discussed. A total of 48 species of ectoparasites are recorded, i.e. 25 species of Copepodal 15 or Monogenea, 2 of Branchiura, 5 of Isopoda, and 1 of Hirudinea. Most parasite species have a wider geographical range than their main host species and do not conform to the zoogeographical regions established for free-living species. The monogeneans are host specific to the genus Acanthopagrus though they are commonly found on more than one species. Udonella has been...

SUSCEPTIBILITY OF SOME SPECIES OF RODENTS TO RICKETTSIAE

REHACEK J, URVOLGYI J, KOCIANOVA E, JEDLICKA L

Folia Parasitologica 39[3] 265-284 (1992)

The present study was designed to test the susceptibility of free living rodents, viz Apodemus flavicollis, Microtus arvalis, Clethrionomys glareolus, Mus musculus, and outbred white mice from Dobra Voda farm, CSFR, to Coxiella burnetii, rickettsiae of the spotted fever group (Rickettsia sibirica, R. conorii, R. slovaca and R. akari) and rickettsiae of typhus group (R. typhi and R. prowazekii) by various routes of administration. The highest levels of antibodies to C. burnetti were found in A. flavicollis and M. arvalis inoculated intraperitoneally and intracerebrally. Antibodies to C. burnetii exerted peak levels between days 13 and 16 in contrast...
