Formation of coronary arteries sprouting from the primitive aortic sinus wall of the chick embryo.

The formation of coronary arteries in chick embryos was observed by scanning electron microscopy on injected casts as well as by transmission electron microscopy. Usually, 2-4 primitive coronary arteries appear from the right aortic sinus below the level of the cusp margin, and 1-3 from the left one. As development proceeds, the arteries are generally reduced in number to form a single definitive coronary artery on each side. Canalization of the arteries seems to take place by partially degenerative changes of the primordia.

Isolation of bacteriophages for typing staphylococcus intermedius isolated from pigeons.

Attempts to isolate phages for typing Staphylococcus intermedius isolated from pigeons were made. Five phages were isolated from the lysogenic strains and the nostrils of pigeons, and were used for typing 50 strains isolated from pigeons in Japan, Belgium and Czechoslovakia. Thirty-one (62.0%) of the 50 strains were typed at either routine test dilution (RTD) or 100 X RTD into 8 phage patterns. A total of 122 strains of S. intermedius isolated from dogs, horses, mink and foxes were subjected to phage typing with pigeon phages, with the result that 10 (8.2%) of the 122 strains were typable. S. aureus and S. epidermidis, 59 and 58 strains, respectively, were resistant to lysis due to the pigeon phages. The experimental phages were considerably specific for S. intermedius isolated from pigeons.

Experimental bacteriophage set for typing Staphylococcus intermedius.

A new phage set for typing Staphylococcus intermedius is proposed. By using 14 phages, 581 strains isolated from dogs, pigeons, horses, foxes and mink were subjected to typing at routine test dilution (RTD) and 100 X RTD. The typability of each ecovar ranged from 78.9% to 100%. Most of the strains were typable at RTD. Phage patterns obtained could be divided into 4 types (Canine I, Canine II, Pigeon, and Equine). The phage set was considered useful for typing S. intermedius.
