AIMS A microbiological study of uncooked ready-to-eat organic vegetables was undertaken to determine the microbiological quality of these vegetables on retail sale in the UK. METHODS AND RESULTS Organic vegetables were collected and examined according to a standardized protocol. The majority (3185 of 3200; 99.5%) of samples were found to be of satisfactory/acceptable quality whilst only 15 (0...

The diagnosis of ASB is the most important step in managing ASB. As stated at the article the most important point for diagnosis is microbiological tests. In this context the number of specimens for culture is crucial. In guidelines ASB in men is defined as the isolation of ≥ 105 cfu/mL bacteria in a single cleancatch voided urine specimen. On the other hand in women, two consecutive urine spec...

Frequent use of Xylitol may decrease the S. mutans levels. However, very little is known about whether this effect on the levels of cariogenic bacteria is maintained after the interruption of short-term usage of xylitol. This study aimed at evaluating changes in mutans streptococci (MS) salivary levels after using a chewing gum containing xylitol. Twelve volunteers harboring > or = 10(5) CFU MS...

This research illustrates the qualitative and quantitative composition of the mycoflora of both a green compost (thermophilically produced from plant debris) and a vermicompost (mesophilically produced by the action of earthworms on plant and animal wastes after thermophilic preconditioning). Fungi were isolated using three media (PDA, CMC, PDA plus cycloheximide), incubated at three temperatur...

Bacterial suspension containing 10 colony forming units (cfu) of Xanthomonas oryzae pv. oryzae was used for inoculating detached leaves of 6 commercial rice cultivars In vitro as well as for testing these cultivars in pots in growth chamber conditions by three methods of inoculation i.e., clipping, pin prick and brush respectively. Clipping method resulted in much more lesion length development...

Contamination of hospital surfaces by bacteria is increasingly recognized. We assessed commonly touched surfaces using contact plates and Petrifilms (3M, St. Paul, MN) and compared the results against proposed microbiology standards. Toilet door handles were the most heavily contaminated (7.97 ± 0.68 colony forming units [CFU]/cm(2)) and exceeded proposed standards on 74% of occasions. Petrifil...

The structure of Aspergillus flavus communities associated with south Texas cottonseed was determined by analysing samples from 178 truckloads of commercial cottonseed from 35 gins, extending from Fort Bend County in the north to the Rio Grande Valley in the south, from September 1999 to October 2001. The number of colony-forming units (CFU) of A. flavus on the cottonseed, and the percentage of...

AIM The aim of this paper is to provide information about the concentrations of airborne bioaerosols (airborne bacteria, fungi and endotoxins) in outdoor suburban environments in Ostrava, Moravian-Silesian region, Czech Republic. METHODS The methods were based on systematic bioaerosol monitoring during one calendar year, subsequent analysis of the samples and statistical processing. The regre...

The main objective of the present study was to assess culturable airborne fungal concentrations, and types in different seasons. Two-stage viable impactor samplers were used with malt extract agar medium as the collection media. Culturable airborne fungal concentrations were collected indoors and outdoors of 43 homes in urban and rural environments from November 2008 to October 2009 in Egypt. F...

Sequences from -3500 to +1365 of the chicken histone H5 gene have been analyzed for the presence of cis-acting elements in H5 expressing (transformed CFU-E) and non-expressing cells (fibroblasts). The region from -3500 to -115 had little effect on transcription. Proximal upstream sequences contain a negative element (UNE, -115 to -95), capable to also repress the activity of the heterologous HS...
