SUMMARYA comparative study of 50 strains of Acetomourn and 165 strains of Pseudomonas showed that the two genera could be easily and rapidly differentiated by the use of four criteria; these were: (a) production of acid on ethanol + CaCO, agar plates,

Twenty-three cases of porcine cystitis and pyelonephritis were examined bacteriologically. Eubacterium suis was found in 21 cases. The isolation of large numbers of Escherichia coli in the upper urinary tract was associated with linear renal scarring. An unidentifiable streptococcus and Enterococcus faecalis were isolated from a case of purulent ureteritis, pyelitis and pyelonephritis. The bacterial flora from cases of cystitis and pyelonephritis was different from that isolated from sows with asymptomatic bacteriuria.

Summary: Most heterofermentative lactic rods occurring throughout the cider industry are quite similar and form a fairly coherent group. The constituent bacteria are sufficiently different from other heterofermentative lactobacilli to be considered a new species. They have, therefore, been named Lactobacillus collinoides nov. spec. These occur most frequently in factories where sulphur dioxide, the only permitted preservative, is either used in small quantities or not at all.

Summary. This paper describes some homofermentative lactobacilli, found in freshly pressed apple juice, which can be divided into two groups. One of these consists of strains identified as Lactobacillus plantarum, of which nearly all can metabolize quinic acid. The other group, which consists mainly of catalase positive bacteria, is composed of strains alike enough to be grouped together but sufficiently different from other lactobacilli to be proposed as Lactobacillus mali nov. spec.
