โœฆ Synopsis

A novel plate assay method, developed for the screening of microorganisms or enzyme preparations for phenolic acid esterases, involves incorporating ethyl cinnamate into an agar medium. After inoculation and incubation, the plate is flooded with a pH-sensitive dye to reveal yellow zones around positive cultures against a blue background.

A number of yeasts (Rhodotorula spp. and Candida spp.) and fungi (PenicilIiurn sp. and Aspergillus sp.) gave positive results, while a number of commercial enzymes, particularly pectinases, also exhibited good phenolic acid esterase.

## Abstract Diagnosis of erythrovirus B19 relies on serology and the detection of viral DNA. These techniques were believed to detect all field isolates because erythrovirus B19 has been known to undergo little genetic variation (1โ€“2%). Recently, a distinct erythrovirus isolate termed V9, markedly
