Genus Balkanella Castellani and Chalmers, 191 8. 



Definition,— Ebertheae which ferment glucose completely with the 

 production of acid and gas; lactose not fermented. Milk clotted. 



Type Species,— 'Balkanella coagulans Castellani, 1916. 



Remarks. — ^There are two species— viz., the type and B. caroli- 

 noides Castellani— which may be separated as follows :■ — • 



Genus Wesenbergus Castellani and Chalmers, 1918. 



Definition. — ^Ebertheae which ferment glucose completely and 

 lactose partially, producing acid, but no gas. Milk not clotted 



Type Species. — -Wesenlergus wesenhergi Castellani, 1913. 



Remarks. — -The type described by Castellani is motile, and pro- 

 duces acidity in litmus milk. It forms acid and gas in glucose and 

 saccharose, but only acid in lactose, mannitol, and dulcitol. It is 

 an indol producer. 



To the same group belongs Wesenbergus giumai Castellani, which 

 is non-motile. 



Archibald in the Anglo-Egyptian Sudan obtained an organism 

 of this type from the blood of a case of enteroidea in Khartoum on 

 the fifth day of the illness. It was motile, formed acid and gas in 

 glucose, galactose, and rhamnose (iso-dulcite), dextrin, starch, 

 mannitol, and sorbitol, but only acid in lactose, levulose, maltose, 

 and dulcitol, while it failed to ferment saccharose, raffinose, inulin, 

 salicin, glycerol, erythrol, or adonitol. It did not produce indol, 

 gave a negative Voges-Proskauer reaction, but reduced nitrates and 

 neutral red. Specific serum reactions separated it from Eberlhus 

 typhosus, Salmonella paratyphi, S. paratyphosa, and 5. gaertneri, 

 and it was well agglutinated by the patient's serum during 

 convalescence. We name it Wesenbergus fermentosus.
