Properties of an encephalitogenic canine parainfluenza virus.
An isolate of canine parainfluenza (CPI) virus from the cerebrospinal fluid of a dog with neurological dysfunction was characterized in vitro in comparison to a prototype strain of CPI virus, D008. The virus, designated 78-238 was found to be antigenically related to CPI virus (Manhatten strain) and simian virus 5 (SV5), but not to mumps virus (Enders strain). Ultrastructural observation of gradient-purified 78-238 virus revealed enveloped pleomorphic virions with helical nucleocapsid symmetry. Preliminary pathological studies indicated that 78-238 virus was encephalitogenic for gnotobiotic dogs when inoculated by the intracerebral route.

[Congenital tuberculosis (author's transl)].
A prematurely born infant (35 weeks of gestational age) developed signs of respiratory insufficiency, and fever, beginning at the 17th day of life; x-ray examinations showed small and large spotted lung infiltrations which grew and confluated rapidly in spite of broad antibiotic treatment. At the 29th day intubation and artificial ventilation became necessary; cultures of tracheal fluid remained sterile, Ziehl-Neelsen stains were not done. The infant died at the age of 35 days. Only at autopsy the diagnosis " congenital tuberculosis" could be made; examinations of the mother who was thought to be healthy, revealed a severe epitheloid cell tuberculosis of the endometrium. -- Mode of transmission, pathology, clinical symptoms, prophylaxis, and therapy of congenital tuberculosis are being reviewed.

Experimental genital tract infection with Chlamydia psittaci (GPIC agent) in male rats.
The course of experimental chlamydial infection of the male genital tract was studied. Inoculation of the Chlamydia psittaci agent of guinea pig inclusion conjunctivitis (GPIC agent) into the vas deferens of rats resulted in chlamydial infection of the epididymis, testis and the prostate gland. The inflammatory response was most prominent at 14 days after infection. Chlamydiae were recovered from the epididymides and the prostate glands for up to 90 and 60 days post inoculation, respectively. Histopathological changes associated with chlamydial infection of the epididymis or prostate gland were characterized by intratubular and interstitial purulent inflammation. Chlamydia-specific IgM- and IgG-antibodies were found in sera of nearly all infected animals. Results of this study indicate that this animal model may be useful to study the pathogenesis, immune responses and sequelae of chlamydial infections of the male genital tract.
