background: artemisia species with common persian name of dermaneh are found all over iran and are used for treatment in infectious diseases such as malaria, hepatitis and other diseases. some artemisia species are used in traditionally as tonic and anti-helmintic in north of iran. objective: the aim of this study was to investigate chemical composition of the essential oil of artemisia hausskn...

Quantitatively, wounds harboring bacteria that exceed 105 colony-forming units per gram are considered infected wounds. There are acute wounds and chronic wounds, and the approach to controlling the infection is similar. Although the granulating bed may be avascular, systemic anti-infectives are employed adjunctively to circumvent systemic infection. The main armamentarium of the attack is the ...

All Yersinia species target and bind to phagocytic cells, but uptake and destruction of bacteria are prevented by injection of anti-phagocytic Yop proteins into the host cell. Here we provide evidence that CD8(+) T cells, which canonically eliminate intracellular pathogens, are important for restricting Yersinia, even though bacteria are primarily found in an extracellular locale during the cou...

Microbial resistance to antibiotics has been raised over time, creating a serious burden and an issue that requires quick response. As result, interest shifted medicinal plants as natural, effective, cost-efficient alternatives. The goal of this study was assess the antibacterial antifungal activities dried buds clove’s flowers, which were extracted in 250 ml ethanol using Soxhlet apparatus. Su...

Endophytic bacteria are that live in plant tissue without causing negative effects. can produce bioactive compounds be used as antibacterial, anti-fungal, antiviral, anti-cancer, anti-diabetic, antimalarial and anti-immunosuppressive properties. found all higher plants, one of which is balakacida (Chromolaena odorata). This study aims to isolate the endophytic from Banda Aceh, test antimicrobia...

2-(2',4'-Dibromophenoxy)-4,6-dibromophenol isolated from the marine sponge Dysidea granulosa (Bergquist) collected off the coast of Lakshadweep islands, Indian Ocean, exhibited potent and broad spectrum in-vitro antibacterial activity, especially against methicillin resistant Staphylococcus aureus (MRSA), methicillin sensitive Staphylococcus aureus (MSSA), vancomycin resistant Enterococci (VRE)...

A new series of 2-(5-nitro-2-heteroaryl)-1,3,4-thiadiazole derivatives, including nitro furan, nitro thiophene and nitro imidazole, were synthesized and screened in vitro for their inhibitory activity against eight bacterial strains. The results showed that most of the synthesized compounds were active against Gram-positive bacteria, determined by MIC method. Among them, compounds <str...

abstract biofilm is a complex community of microorganisms residing within a polysaccharide and/or protein matrix. biofilm can be produced by microorganisms such as bacteria and fungi. both gram positive and gram negative bacteria have this ability. resistance of biofilm to antimicrobial agents is becoming a global issue. bacterial biofilms are important in various aspects such as chronic human ...

abstract- lactic acid bacteria are commonly found in the gastrointestinal tract of various endothermic animals and humans, in milk, dairy and seafood products and on some plant surfaces. the aim of this study was to investigate the inhibitory effect of isolated lactic acid bacteria from intestines of narrow-barred spanish mackerel (scomberomorus commerson) on listeria innocua growth. five strai...

Anti-N-methyl-d-aspartate (Anti-NMDA) receptor encephalitis is an acute autoimmune neurological disorder. The cause of this disease is often unknown, and previous studies revealed that it might be caused by a virus, vaccine or tumor. It occurs more often in females than in males. Several cases were reported to be related to vaccination such as the H1N1 vaccine and tetanus/diphtheria/pertussis a...
