Background: Consumption of raw cheese may be associated with different diseases. This study aimed to evaluate behavior of four pathogenic bacteria during manufacture and ripening of Protected Designation of Origin (PDO) Pecorino Siciliano cheese. Methods: The experimental cheese groups were inoculated with pathogenic bacteria, including Escherichia coli O157, Listeria monocytogenes, Salmonella...

OBJECTIVE To study bacteria and viruses in maxillary sinuses of patients with primary hypogammaglobulinemia receiving immunoglobulin therapy. DESIGN Prospective cross-sectional study during 6 months. SETTING Tertiary care university hospital. PATIENTS Seventeen patients with primary hypogammaglobulinemia (10 males and 7 females; mean age, 39 years [age range, 11-71 years]). Sixteen patien...

BACKGROUND Respiratory infections are well known triggers of asthma exacerbations, but their role in stable adult asthma remains unclear. METHODS 103 asthmatics and 30 control subjects were enrolled in the study. Sputum was induced by inhalation of 3% NaCl solution. Oropharyngeal swab specimens were obtained from the posterior wall of the oropharynx. Respiratory specimens were analysed by RT-...

We propose that clonal evolution in micropathogens be defined as restrained recombination on an evolutionary scale, with genetic exchange scarce enough to not break the prevalent pattern of clonal population structure, a definition already widely used for all kinds of pathogens, although not clearly formulated by many scientists and rejected by others. The two main manifestations of clonal evol...

High throughput sequencing (HTS) creates an opportunity for comprehensive genomic studies. It can be applied in veterinary science, bacteriology and virology, diagnostics of animal diseases, food safety, examinations the composition environmental samples, even vaccinology. Thus HTS a wide-ranging method that different areas One Health approach. In particular, whole genome (WGS) bacteria is rout...

Background and Aim: This research aims to study the qualitative melissopalynology analysis, Glucose oxydase (GOX) activity, and the antibacterial effect of honey samples from different botanical and geographical origins. Materials and Methods: Five natural honey samples were collected from local beekeepers. The antibacterial effect was carried out towards pathogenic bacteria including Escheric...

Title of Document: FATE OF BACTERIAL AND VIRAL INDICATORS IN AN ADVANCED WASTEWATER TREATMENT PLANT Chung-Che Liang, Master of Science 2013 Directed By: Professor Krista Wigginton Department of Civil and Environmental Engineering Wastewater treatment plants (WWTP) are natural aggregators of pathogenic organisms due to the waste they treat. This study examined the fate of two bacterial indicator...

Water and leafy vegetables eaten fresh are increasingly reported as being involved in food-borne illness cases. The pathogenic agents responsible for these infections are mainly bacteria and viruses and are present in very small quantities on the contaminated food matrices. Laboratory techniques used to isolate or detect the contaminating agent differ enormously according to the type of microor...

Background and Objectives: Vibrio parahaemolyticus is the causative agent of gastroenteritis due to consumption of contaminated seafood. The aim of the present study was to determine the chemical composition of Essential Oils (EOs) of five plants (Artemisia absinthium, Zataria multiflora Boiss., Pulicaria gnaphalodes, Trachyspermum ammi and Cuminum cyminum) and to evaluate their antimicrobial a...

Wetlands containing floating, emergent and submergent aquatic plants, and other water-tolerant species have been found to economically provide a mechanism of enhancing the quality of domestic wastewater. The use of constructed wetlands for the removal of indicator bacteria (total and fecal coliforms), coliphages, protozoan parasites (Giardia and Cryptosporidium) and enteric viruses was investig...
