Materials used in ossicular replacement prostheses must possess appropriate biological properties, such as biocompatibility, stability, no cytotoxicity. Due to the risk of infection (otitis media and chronic otitis media), it is desirable to use an antibacterial agent for illness prevention during the ossicular reconstruction. The goal of this work was to observe biological properties of a new ...

The contamination of the surface water lagoons is a common problem in developing countries, and can affect fishing activities. A case study was conducted on quality microbiological marketing chain Peruvian Amazon (Laguna de Yarinacocha). microbiological, physical–chemical parasitological parameters were evaluated three points lagoon near landing stage; facilities, handlers species fish (Prochil...

In this research work, there was analysis of the levels heavy metals and antibioticsensitivity bacteria present from waste dumpsites in Benin City, Edo state. Themethodology involved collection samples triplicates randomdumpsites. The sites were Ekosodin, Oluku Uselu all within City metropolis. Also,standard pour plating method with dilution to 10-3 done isolate organisms soil samples. Analysis...

Non-fermenters are aerobic non-spore forming Gram-negative bacilli that either incapable of catabolized carbohydrates as a source of energy or degrade them via oxidative rather than fermentative metabolic pathways. In the group of non-fermenters Pseudomonas aeruginosa is eminent pathogen followed by Acinetobacter baumanni. Both of these organisms are reported for their intrinsic resistance agai...

In the present study, samples of rhizosphere and root nodules were collected from different areas of Pakistan to isolate plant growth promoting rhizobacteria. Identification of bacterial isolates was made by 16S rRNA gene sequence analysis and taxonomical confirmation on EzTaxon Server. The identified bacterial strains were belonged to 5 genera i.e. Ensifer, Bacillus, Pseudomona, Leclercia and ...

Cecropins (Cec) are antibacterial peptides and their expression is induced in a pig intestinal parasite Ascaris suum by bacterial infection. To explore the usefulness of its activity as an antibiotic, CecP4 cDNA was prepared and cloned into the pPICZ B expression vector and followed by the integration into AOX1 locus in Pichia pastoris. The supernatants from cell culture were collected after me...

Neste estudo, óleos de oliva e girassol ozonizados foram comparados química e microbilogicamente. Estes óleos foram introduzidos em um reator com gás ozônio borbulhante, em banho-maria a temperatura ambiente, até solidificação. O teor de peróxido, de iodo e o grau de acidez foram determinados juntamente com a atividade antimicrobiana. Os efeitos da ozonização na composição dos ácidos graxos des...

Background: Empyema thoracis may occur from parapneumonic pleural effusion and is associated with prolonged respiratory symptoms requiring longer times for drainage. Suppurative bacterial infections and tuberculosis are important causes; which if not treated early, may result to chronic empyema requiring thoracotomy and decortication. Objectives: To highlight the diagnostic and treatment challe...

The increased survival of patients with cystic fibrosis (CF) resulted in the appearance of new pulmonary and non-pulmonary complications. Even though subjects with CF present with inflammatory pulmonary changes at birth, several pathogens such as Staphyloccocus aureus, Haemophilus influenzae and Pseudomona aeruginosa contribute to the progression of pulmonary injury. Clinical presentations vary...

The aim of this study was to evaluate the antibacterial effects of Thymus vulgaris, Thymus caramanicus, Zataria multiflora, Ziziphora clinopodioides and Ziziphora tenuior against four foodborne and four other bacteria including Staphylococcus aureus, Shigella dysenteriae, Salmonella typhimurium, Escherichia coli, Staphylococcus epidermidis, Bacillus subtilis, MRSA and Pseudomona aeruginosa and ...
