    Notes: Summary  We determined the prevalence of antineutrophil cytoplasmic antibodies (ANCAs) in patients with systemic lupus erythematosus (SLE) and evaluated the correlation between ANCA positivity and clinical features. Forty-one patients with SLE and two control groups were examined. One of the control groups consisted of 15 patients with systemic vasculitis, and the other of 12 healthy blood donors. A quantitative enzyme-linked immunosorbent assay technique was used to measure the serum cytoplasmic ANCA (cANCA) and perinuclear ANCA (pANCA) levels. cANCA positivity was found in three patient samples, and pANCA positivity in 10 SLE patients. The occurrence and titres of both ANCA types in SLE patients were similar to those in healthy controls and significantly lower than those in patients with systemic vasculitis. The clinical picture and antibody profile were similar in ANCA-positive and ANCA-negative SLE patients. We conclude that measurement of ANCAs does not provide any additional diagnostic or prognostic data in SLE.

    Experimental induction of Sphaerospora renicola (Myxosporea) infection in common carp (Cyprinus carpio) by transmission of SB-protozoans (1986)

    Notes: The authors have experimental evidence that the protozoa causing the swimbladder inflammation (SBI) of the common carp (Cyprinus carpio) are indentical with presporogonic stages of Sphaerospora renicola Dyková et Lorn, 1982 parasitizing the renal tubules. Homogenates prepared from the thickened and inflamed swimbladder of naturally infected common carp, when injected into the abdominal cavity of fish, produced renal sphaerosporosis in the infection-free common carp if the homogenates contained the parasites described by Kovács-Gayer et al. (8). By intraperitoneal injection, the Unidentified Blood Organisms (UBOs) living in the blood of the common carp were transmissible to common carp, from the blood of which they were demonstrable for a long time. However, they were not transformed into Sphaerospora. To other cyprinids (gibel carp, silver carp, grass carp, tench, roach) neither the blood stages nor the swimbladder stages were transmissible from the common carp.

    Notes: Our results show that mebendazole is an effective agent for controlling pseudodactylogyrosis. Exposure of the fish to a solution containing 100 mg/l mebendazole for 10 min killed Pseudodactylogyrus bini and P. anguillae; a mebendazole concentration of 1 mg/l produced the same effect after an exposure of 24 hours. Although the helminths suffered damage immediately after exposure to mebendazole, it took six days before they disappeared from the gills. For short (10 min) exposures, the efficacy of mebendazole was enhanced tenfold by previously exposing the eels (Anguilla anguilla) to saline (NaCl).〈section xml:id="abs1-2"〉〈title type="main"〉ZusammenfassungMebendazol als wirksames Medikament gegen die Pseudodactylogyrosis des Europäischen Aals (Anguilla anguilla)Mebendazol erwies sich als wirksam gegen Pseudodactylogyrus bini und P. anguillae. Das Präparat tötete die Parasiten in folgenden Dosen: 100 mg/l im Kurzzeitbad (10 Minuten) bzw. 1 mg/l im Langzeitbad (24 Stunden). Obwohl die Parasiten durch Mebendazol sofort geschädigt wurden, waren die Kiemen der Aale erst 6 Tage nach der Behandlung parasitenfrei. Ein vorangegangenes Kochsalzbad steigerte die Wirkung des Mebendazol auf das Zehnfache im Kurzzeitbad.〈section xml:id="abs1-3"〉〈title type="main"〉RésuméLe mebendazole comme médicament efficace contre la pseudodactylogyrose de l'anguille européenne (Anguilla anguilla)Le mebendazole s'est révéléêtre efficace pour le contrôle de la pseudodactylogyrose.

Bien que les parasites aient été immédiatement touchés par le mebendazole, cela a duré 6 jours avant qu'ils ne disparaissent des branchies des anguilles. En cas de bain de courte durée (10 minutes) l'efficacité du mebendazole a décuplé lorsque les anguilles (Anguilla anguilla) avaient été préalablement baignées dans une solution saline (NaCl).

    Notes: In elvers (Anguilla anguilla) imported yearly to a fish farm in Hungary the regular occurrence of a Myxobolus infection was recorded. The parasite produces oval or spherical plasmodia of 0.1–0.2·0.07–0.12mm in the subcutaneous and intermuscular connective tissue of the head. In each piasmodium about 200 to 400 spores develop which differ morphologically from the spores of all Myxobolus species known from the eel and other fishes. Based upon the characteristic location of plasmodia and spore morphology, this parasite is described as a new species, Myxobolus kotlani.

    Light and electron microscopic studies on Epieimeria anguillae (Léger & Hollande, 1922), a coccidium parasitizing the European eel, Anguilla anguilla L. (1986)

    Notes: Abstract. The foregut of eels naturally infected by Epieimeria anguillae (Léger & Hollande, 1922) was studied by light and electron microscopy. It has been established that this parasite, which develops in a characteristic location on the surface of epithelial cells, and was classified on this basis by Dyková & Lom (1981) as a member of the genus Epieimeria, undergoes intracellular merogony and gamogony similarly to other eimerians; however, its sporogony takes place outside the fish or intercellularly. The trophozoites and merogonic and gamogonic stages each develop in a para-sitophorous vacuole which is half embedded in the epithelial cell and protrudes into the intestinal lumen. The parasitophorous vacuote is surrounded by a single membrane; however, towards the intestinal lumen it is covered also by the cell membrane. In its location, Epieimeria anguillae resembles cryptosporidia, but differs from the latter significantly in its relationship with the host cell.

    Notes: The development of Myxobolus bramae Reuss 1906, a myxosporean parasite of the gills of common bream Abramis brama L., was studied in experimentally infected oligochaetes. In five experiments, uninfected Tubifex tubifex (Müller) and Limnodrilus hoffmeisteri Claparéde were exposed to mature myxospores of M. bramae. In four experiments triactinomyxon type actinospores developed in Tubifex specimens but no infection was found in Limnodrilus. Actinospores were released from oligochaetes 70–81 days after initial exposure. At that time pansporocysts containing eight actinospores were located in the gut epithelium of experimental oligochaetes, but free actinosporean stages were also found in their gut lumen. Each actinospore had three pyriform polar capsules and a barrel-shaped sporoplasm with 32 secondary cells. The spore body joined the three caudal projections with a stout style. The total length of the actinospore was 139 μm on the average.

    Notes: The validity of Myxobolus species infecting the skeletal muscles of six cyprinid fish species was studied by morphological and molecular biological methods. Intracellularly developing Myxobolus spores identified as M. cyprini from the common carp, M. musculi from the barbel, and M. pseudodispar from the roach, rudd, common bream and white bream were very similar in their shape and size. Nonetheless, in species identified as M. pseudodispar, the occurrence of spores with an asymmetrical shape was higher than in M. cyprini, while asymmetrical spores were only occasionally found in M. musculi. The DNA sequence analysis of the polymerase chain reaction (PCR)-amplified 18S rRNA gene of Myxobolus spores from these fish showed a similar phylogeny to that of their host species. As morphological studies and DNA sequence analysis demonstrated slight but real differences in the spores infecting muscles of the six cyprinid species, it is suggested that M. musculi, M. pseudodispar and M. cyprini are valid species.

    A light and electron microscopic study of the agent of carp mucophilosis (1981)

    Notes: Abstract. The authors failed to detect algae or fungi in the gills of carp showing the typical clinical signs of mucophilosis. Electron microscopic examination showed the presence of rickettsia- or chlamydia-like organisms, inside the characteristic mucophilus cysts. These organisms are believed to be the causative agents of mucophilosis. The organisms develop intracellularly in the gill epithelium and after several divisions give rise to mucophilus cysts 70–80 μm in diameter. The morphological and ultrastructural changes observed in the course of mucophilosis bear a striking resemblance to the cysts and cyst-inducing causative agents responsible for epitheliocystis disease.
