background: most of the population in the different areas of world is affected by bacterial infections responsible for dental caries. due to the importance of traditional medicines derived from herbs used for dental problems, this study investigated in vitro antibacterial activity of mentha longifolia essential oil from ardabil, iran, on streptococcus mutans, lactobacillus rhamnosus and actinom...

Phytochemical screening, antioxidant and antibacterial activities of aqueous and methanolic crude extracts of Commiphora kerstingii leaves were investigated. The antioxidant and antibacterial properties of different solvent extracts of Commiphora kerstingii plant were scrutinized. The phytochemical screening of the various extracts was carried out using standard methods and the results revealed...

introduction group a β-hemolytic streptococcus is the most common cause of bacterial pharyngitis among 5 - 15-year-old children, but it is uncommon in children less than three years old and rarely happens in infants less than one year old. case presentation the patient was a 62-day-old female infant who presented with fever and poor feeding since two days before admission. at the time of admiss...

The main objective of this study is removal of pathogenic bacteria using electrochemical process. The bactericidal effects of electrochemical system containing steel mesh electrode were evaluated from contaminated water with E. coli, Pseudomonas aeroginosa, Staphylococcus aureous and Streptococcus fecalis at various concentrations. Effect of current density, supporting electrolyte and pathogeni...

In this study, immune responses against Streptococcus iniae infections in rainbow trout (Oncorhynchus mykiss) were analyzed. Anti-streptococcal antibody (ASA) levels, respiratory burst activity (RBA), phagocytic activity (PA) and phagocytic index (P index) were measured in kidney macrophages. Fish were allocated to three experimental groups (n = 50 per group): survivors of natural S. iniae inf...

Over the past few years, the syndrome of streptococcosis has been associated with outbreaks in rainbow trout (Oncorhynchus mykiss, Walbaum) and caused significant economic losses in the aquaculture industry in Iran. The main purpose of this work was molecular identification of some causative agents of streptococcosis in rainbow trout. A total of 520 samples were collected from the head kidney o...

  Objective: Bioactive glass 45S5 is a surface reactive glass-ceramic biomaterial, developed in 1969. BAG 45S5 with particle size of 20-60 nm has the ability of bone regeneration, broad spectrum antibacterial effect, repairs and replaces diseased or damaged bone. The aim of this study was to evaluate the antibacterial activity and determine MIC and MBC values of nano-BAG45S5 on Streptococcus mu...
