فلور لاکتیکی دو پنیر سنتی ایرانی (لیقوان و کوزه) حاصل از شیر خام و فاقد استارتر ، بوسیله دو روش مبتنی بر کشت و مستقل از کشت مورد بررسی قرار گرفت. سه بهر از پنیر لیقوان و یک بهر از پنیر کوزه جهت ارزیابی ساختار و دینامیک میکروبی در مراحل مختلف تولید و رسیدگی ، در معرض آنالیز مستقل از کشت pcr- dgge و توالی یابی باند های غالب قرار گرفتند. علاوه بر آن، کشت در محیط های انتخابی (m17, mrs و kaa ) برای ...
The objective of this study was to perform a quantitative and qualitative evaluation microbial contamination harvested colostrum on 39 Czech dairy farms. identified the proportion samples that met recommended goals for total plate count (TPC), coliform (TCC), gram-negative noncoliform (NCC), evaluated effect farm, breed, parity, season year, time calving, volume these 3 microbiological paramete...
Background and Aims: Dental caries is the most common infectious diseases. Among the oral bacteria, Streptococcus mutans and Streptococcus sobrinus are considered as the main causes of tooth decay. The aim of this study was to evaluate the production of hyperimmune bovine colostrum containing specific antibodies against cariogenic bacteria and its antimicrobial effects on the growth and adhes...
Background: Significant increases in the bacterial resistance to various antibiotics have been found in fish farms. Non-antibiotic therapies for infectious diseases in aquaculture are needed. In recent years, light-emitting diode technology has been applied to the inactivation of pathogens, especially those affecting humans. The purpose of this study was to assess the effect of blue light (wave...
Background and Aims: Tooth decay has high prevalence in the world. The use of plant material for the prevention and treatment of this disease for various reasons is considered, due to the increasing resistance of bacteria to antibiotics, the high cost and adverse effects of some chemicals used in dentistry. This study was aimed to determine the antimicrobial effect of alcoholic extract of Pep...
objective bacterial adhesion is governed by specific and nonspecific interactions such as hydrophobicity. hydrophobic interactions play a role in the adherence of microorganisms to a wide variety of surfaces and facilitate biofilm formation due to bacterial adhesion. in this article the relation between cell surface hydrophobicity and antibiotic resistance was studied. materials and methods we ...
Background and Aim: Due to the increasing use of restorative materials, finding a suitable material with low adhesion rate and colonization of pathogenic Streptococcus mutans has a significant importance. The purpose of this study was the comparison of the adhesion rate of Streptococcus mutans to “Nano-hybrid composite” and “Amalgam” at 1, 3, and 7 day intervals. Method...
