Cultures grown from patients with bacterial overgrowth syndrome reveal abnormally large numbers of anaerobic bacteria in addition to normal flora.

Screening Screening is the first unit operation used at wastewater treatment plants (WWTPs). Screening removes objects such as rags, paper, plastics, and metals to prevent damage and clogging of downstream equipment, piping, and appurtenances.
