Histochemistry of the racemose form of Cysticercus cellulosae.

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.

Disseminated pulmonary adiaspiromycosis identified in bioptic material from the lung.

A disseminated form of pulmonary adiaspiromycosis was estimated in a 48 year old miner. The origin of a hypersensitivity mainly of an immediate allergic type became evident during an immunological examination and was partly indicated also by the tissue reaction and by elevated level of serum IgE (480 I.U.

Development of oncospheres of Taenia saginata after a concomitant infection by oral and subcutaneous routes.

Two experimental bulls (weight 200 kg each) were infected with activated oncospheres of Taenia saginata. The infective dose (160,000 oncospheres) was administered twice to each animal, once by oral, once by subcutaneous routes. At 6 hr p.

[Differential diagnosis of cysticerci of Taenia hydatigena and hydatids of Echinococcus granulosus].

In combined infestations of pig by hydatids as well as larvae of Taenia hydatigena macroscopic and histological differences were stated which are of great importance for differential diagnosis of these two infestations in veterinary practice.

Tissue reaction to spherical and lobular hydatid cysts of Echinococcus granulosus (Batsch, 1786).

We have studied the tissue reaction to spherical and lobular cysts of Echinococcus granulosus (Batsch, 1786) on a set of 108 observations of hydatidosis in the liver and lung of pigs. Typical of an early response of the host to a growing hydatid cyst is a local allergic inflammation characterized by a heavy infiltration of eosinophiles. If the infection is massive, sensitization increases the tissue reaction, and there is a marked exudation of eosinophiles into the pseudocyst which results in the ultimate death and liquidation of the parasite.

Adiaspiromycosis in large free living carnivores.

Adiaspiromycosis was identified in 6 animals in the examination of the lungs of 90 large carnivores. Emmonsia crescens (Chrysosporium parvum var. crescens) was demonstrated as the causative agent in 5 cases of disease-in the badger (Meles meles), the otter (Lutra lutra) and the fox (Vulpes vulpes).

Histopathological changes and the genesis of adiaspiromycomas in mice infected intraperitoneally with Emmonsia cresens Emmons et Jellison, 1960.

Following an intraperitoneal inoculation with a suspension of aleuries of the funtus Emmonsia crescens, characteristic adiaspiromycomas originate in the abdominal cavity; a generalisation of the infection was caused by lymphogenic and haematogenic dissemination. At first, fragments of the mycelium became implanted and started to grow on the peritoneum; these were quickly destroyed by a gradually increasing leukocytic reaction. In the first month of infection nodules were formed mainly on predisposed sites in the abdominal cavity.

Morphological determination of the age of Cysticercus bovis in very young calves with cysticercosis.

Characteristics and measurements are given for early developmental stages of Cysticercus bovis. The data emerging from our study indicate that the age of a one to two month-old larva from a spontaneous infection can reliably be determined in histological sections. On these grounds we have been able to determine that the cysticercus infection in the two calves (aged 21 and 27 days respectively) had been acquired prenatally.

[Human taeniarhynchosis in the CSSR. Report given during the IVth symposium of the GDR on "Taeniarhynchosis-Cysticercosis" on April 26th, 1974 in Schwerin].

In the CSSR Taeniarhynchosis is not a notifiable disease. The details of frequency of occurrence of this disease are mainly based on investigations by the government medical laboratories, Prague. The number of persons infected with Taeniarhynchus saginatus increased in the last six years to 1700.

Emmonsia parva as causal agent of adiaspiromycosis in a fox.

The authors report on adiaspiromycosis of a fox (Vulpes vulpes) caused by Emmonsia parva. Species diagnosis was made on the basis of dimensions of the fungus found in the lungs of the animal, the histopathological picture of tissue changes and the properties of the isolated culture. The identification of the fungus was also confirmed by experimental infection.
