Concentrations of mesophilic bacteria in a poultry farm over two fattening periods focusing on the presence of staphylococci and enterococci.

The increasing animal numbers have a potential impact on the air quality of stables. The aim of this study was to assess the microbial load in the barn air from the day of entry of the chickens to the day of removal for slaughter. A total of 10 measurements in two fattening periods were conducted in a poultry farm with a capacity of 400 chickens in Styria, Austria.

Background concentrations of airborne, culturable fungi and dust particles in urban, rural and mountain regions.

Geographic location and meteorological factors can affect the content of bioaerosol concentrations. This study was conducted to determine the natural background concentrations of culturable fungal spores and dust particles in three different geographical areas. Focus was given to the dominant airborne genera Cladosporium, Penicillium, Aspergillus and the species Aspergillus fumigatus.

A comparison of mount of preparation and finish lines used by dental students in Damascus University and Al Baath University using (CAD/CAM) scanner.

Introduction: Fixed prosthodontics is considered one of the most vital dental treatments that patients receive. Sometimes, however, complication is encountered along with limited information regarding the quality and precision of preparation. Which that led to the conception of this study in order to highlight the shortcomings and obstacles in an attempt to avoid them.

Comparative study of the effect of BlueM active oxygen gel and coe-pack dressing on postoperative surgical depigmentation healing.

Introduction: Black colored gingiva is an esthetic concern, especially when accompanied by a high lip line or gummy smile.Surgical depigmentation with a scalpel is still considered the golden standard in gingival pigmentation management although it causes an area of open wound, which needs a special management with dressing.This study aimed to comparatively evaluate the effectiveness of reactive oxygen gel species (BlueM gel) and the traditional Coe-Pack dressing on gingival healing and pain after surgical depigmentation.

Multiresistant Bacteria Isolated from Intestinal Faeces of Farm Animals in Austria.

In recent years, antibiotic-resistant bacteria with an impact on human health, such as extended spectrum β-lactamase (ESBL)-containing , methicillin-resistant (MRSA) and vancomycin-resistant Enterococci (VRE), have become more common in food. This is due to the use of antibiotics in animal husbandry, which leads to the promotion of antibiotic resistance and thus also makes food a source of such resistant bacteria. Most studies dealing with this issue usually focus on the animals or processed food products to examine the antibiotic resistant bacteria.

Background Concentrations of Cultivable, Mesophilic Bacteria and Dust Particles in the Air in Urban, Rural and Mountain Regions.

Particulate air components can be of anthropogenic or natural origin. It is assumed that in different geographical areas varying concentrations of mesophilic bacteria are present in the ambient air. The aim of this study was to determine the background concentrations of airborne culturable mesophilic bacteria and particulate matter in the ambient air.

Multiresistant Bacteria Isolated from Activated Sludge in Austria.

Wastewater contains different kinds of contaminants, including antibiotics and bacterial isolates with human-generated antibiotic resistances. In industrialized countries most of the wastewater is processed in wastewater treatment plants which do not only include commercial wastewater, but also wastewater from hospitals. Three multiresistant pathogens-extended spectrum β-lactamase (ESBL)-harbouring Enterobacteriaceae (Gram negative bacilli), methicillin resistant (MRSA) and vancomycin resistant Enterococci (VRE)-were chosen for screening in a state of the art wastewater treatment plant in Austria.

Comparative study of impaction and sedimentation in an aerosol chamber using defined fungal spore and bacterial concentrations.

Biocontamination control is a very significant part of the manufacturing process of sterile drugs. Sterility is frequently monitored by active or passive air sampling measurements, but there are no specific rules as to how this is to be done. This study tested air sampling methods of active impaction and passive sedimentation under standardized conditions.

Culturable fungi in potting soils and compost.

In the present study the spectrum and the incidence of fungi in potting soils and compost was investigated. Since soil is one of the most important biotopes for fungi, relatively high concentrations of fungal propagules are to be expected. For detection of fungi, samples of commercial soils, compost and soils from potted plants (both surface and sub-surface) were suspended and plated onto several mycological media.
