Aus dem Thiosemicarbazid (I) werden mit aromatischen Aldehyden (II) die Thiosernicarbazone (III) hergestellt, die nach Isolierung zu den Thiadiazolinen (IV) cyclisiert werden und auf antibaktenelle Wirkung geprüft werden.

Myiasis is the infestation of tissues and organs of animals or man by fly larvae. We report a human case of external ophthalmomyiasis caused by the larvae of a sheep nasal botfly, Oestrus ovis, for the first time in a veterinary doctor. A 25-year-old veterinary doctor presented with severe symptoms of conjunctivitis. The larvae, 3 in number, were observed in the bulbar conjunctiva and the symptoms of the eye improved within a few hours of their removal. It is important for ophthalmologists to be aware of larval conjunctivitis as a significant possibility in the veterinary fraternity especially during the summer season.

Die Benzaldehyde (I) kondensieren mit Isonicotinsäurehydrazid (II) zu den Aroylhydazonen (III), an die sich die α‐Mercaptocarbonsäuren (IV) unter Ringschluß zu den Thiazolidinonen (V) addieren.
