An investigation of a waterborne outbreak caused by microbiological contamination of the drinking water supply system

Abstract

Background: An outbreak of acute gastroenteritis occurred in March and April 2010 (RR 3,1 (95%; IZ: 1,(5)(6)5),3,1 (95% IZ: 1,(2)(3)(4)(5)(6)(7)(8)1) in 2,3 (95% IZ: 1,(2)(3)(4)3)

Comparison of methods for detection of four common nosocomial pathogens on hospital textiles

“…Classical elution with incubation on selective agar yielded a positive result for sample H, and RODAC plating proved least reliable as the lowest positive result was found in sample F. Klebsiella spp. are coliform bacteria ubiquitous in nature and natural habitants of environmental waters; they can also survive laundering as well as on inanimate surfaces such as hospital textiles (43)(44)(45). In our research, we found that an inoculation of 1000 cfu/mL (sample G) before overnight drying yielded positive results for PCR, while the classical elution method followed by incubation on selective medium yielded positive results after drying of 100 cfu/mL for sample F (initial bacterial concentration 10 4 cfu/mL).…”

Drinking Water Quality and the Geospatial Distribution of Notified Gastro-Intestinal Infections / Kvaliteta Pitne Vode in Geoprostorska Porazdelitev Prijavljenih Črevesnih Okužb

“…One of several risk factors for diarrhea is unsafe drinking water. Microbiologically contaminated drinking water has the potential to cause extensive outbreaks of illness due to the size of the populations served by the distribution system ( 5 , 6 ).…”
