Introduction: Zhumeria majdae is an herbal plant which is only found in Hormozgan province. The aim of this study was to compare the antimicrobial property and toxicity of essential oil (EO) and encapsulated form of the essential oil (EFEO) of Zhumeria majdae. Materials and methods: First, the plant was dried, grinded, and its EO extracted by hydrodistallation. Then, the EO was encapsulated by...

Liquid preparations are particularly susceptible to microbial growth because of the nature of their ingredients. Such preparations are protected by the addition of preservatives that prevent the alteration and degradation of the product formulation [1]. The finished product release specifications should include an identification test and a content determination test with acceptance criteria and...

BACKGROUND Present investigation deals with antimicrobial screening of ten medicinally important plants used by the inhabitants of district Haripur, Khyber Pakhtunkhwa (KPK) for different infectious diseases.

INTRODUCTION An ideal intracanal medicament should be able to eliminate any remaining intracanal microorganism. The aim of this study was to compare the antimicrobial effects of Bioglass 45S5 with calcium hydroxide on Enterococcus (E) faecalis in-vitro. MATERIALS AND METHODS Direct exposure test (DET) was used to evaluate the antimicrobial effect of Bioglass 45S5, calcium hydroxide and normal...

Isolates of Staphylococcus aureus from bovine clinical and subclinical mastitis were tested for ß-lactamase production and antimicrobial susceptibility pattern. Beta-lactamase production was assessed by penicillin-phenol red acidometric test. Antimicrobial susceptibility was tested by measuring MIC by Resazurin dye broth microdilution method. Forty per cent of isolates tested were positive for ...

Antimicrobial packaging is one of the most promising active packaging systems. Antimicrobial packaging is the packaging system that is able to kill or inhibit spoilage and pathogenic microorganisms that are contaminating foods. A tremendous effort has been made over the last decade to develop and test films with antimicrobial properties to improve food safety and shelf life. For food preservati...

background and objectives: presence of methicillin and multidrug resistance has associated coagulase negative staphylococci (cns) with high morbidity and mortality worldwide. the present study was carried out to study the susceptibility pattern of cns to various antimicrobial agents and to determine the prevalence of cns methicillin resistance in our hospital setting. materials and methods: a t...

Antimicrobial activity of 25, 50, 75 and 100% alcohol extract of Piper nigrum (Black Pepper), Psidium guajava (Guava), Amomum cardamom (Cardamom) and Cynogen dactylon (Bermuda grass) has been evaluated against Pseudomonas lundensis, Bacillus cereus, Aspergillus niger and Aspergillus flavus. Psidium guajava extract showed excellent antimicrobial activity against all the test organisms. In 25% co...
