Assessment of Physicochemical and Microbiological Quality of Public Swimming Pools in Addis Ababa, Ethiopia.

Background: From swimming pools, bathers may acquire many potential pathogens or may be affected by the physicochemical characteristics of water used during bathing. Hence, this study aimed at assessing the physicochemical and microbiological quality of public swimming pools located at different hotels and recreation center in Addis Ababa, Ethiopia.

Method: A cross sectional study was carried out from February to May, 2016.

A genus-specific PCR method for differentiation between Leuconostoc and Weissella and its application in identification of heterofermentative lactic acid bacteria from coffee fermentation.

A genus-specific PCR analysis method was developed for a rapid and reliable differentiation between the two heterofermentative lactic acid bacteria genera Leuconostoc and Weissella. Primer sets specific for target regions of the 16S rRNA genes were designed and the specificity of the PCR was evaluated using the type strains of 13 species of Leuconostoc and 11 species of Weissella. In addition, the newly developed genus-specific PCR analysis was applied to characterize 72 lactic acid bacteria (LAB) strains isolated from coffee fermentation and which were presumptively classified as Leuconostoc or Weissella species.
