Ethanolic extracts of 45 Indian medicinal plants traditionally used in medicine were studied for their antimicrobial activity against certain drug-resistant bacteria and a yeast Candida albicans of clinical origin. Of these, 40 plant extracts showed varied levels of antimicrobial activity against one or more test bacteria. Anticandidal activity was detected in 24 plant extracts. Overall, broad-spectrum antimicrobial activity was observed in 12 plants (L. inermis, Eucalyptus sp., H. antidysentrica, H. indicus, C. equistifolia. T. belerica, T. chebula, E. officinalis, C. sinensis, S.

A green rapid biogenic synthesis of silver nanoparticles (Ag NPs) using Terminalia chebula (T. chebula) aqueous extract was demonstrated in this present study. The formation of silver nanoparticles was confirmed by Surface Plasmon Resonance (SPR) at 452 nm using UV-visible spectrophotometer. The reduction of silver ions to silver nanoparticles by T. chebula extract was completed within 20 min which was evidenced potentiometrically.

The nematode Caenorhabditis elegans has in recent years been proven to be a powerful in vivo model for testing antimicrobial compounds. We report here that the alkaloid compound Harmane (2-methyl-?-carboline) increases the lifespan of nematodes infected with a human pathogen, the Shiga toxin-producing Escherichia coli O157:H7 strain EDL933 and several other bacterial pathogens. This was shown to be unrelated to the weak antibiotic effect of Harmane. Using GFP-expressing E. coli EDL933, we showed that Harmane does not lower the colonization burden in the nematodes.

It is suggested that pathogen and parasite avoidance act as a driving force for kin selection. Preferential association with relatives decreases the probability of infection with unfamiliar pathogens. Altruistic behavior towards kin will further decrease the danger of infection by increasing the representation of relatives in a group. Such a behavioral strategy could evolve if pathogen resistance were heritable. Highly polymorphic major histocompatibility (MHC) genes largely determine heritable resistance to particular pathogens.

Almost all skin diseases are caused by a variety of factors with psychogenic factors having a great influence on progression and the development of chronic conditions. After remarks on this aspect, the techniques employed in hypnosis therapy are described and psychosomatic skin diseases are outlined. Personal experience in the treatment of viral skin diseases is then described in detail and some aspects of the treatment of bacterial, reactive and psychosomatic diseases are presented. Behavioural disturbances related to dermatological problems and essential pruritus are also mentioned.

Atopic dermatitis, also known as atopic eczema, is a chronic pruritic skin condition affecting approximately 17.8 million persons in the United States. It can lead to significant morbidity. A simplified version of the U.K. Working Party's Diagnostic Criteria can help make the diagnosis. Asking about the presence and frequency of symptoms can allow physicians to grade the severity of the disease and response to treatment. Management consists of relieving symptoms and lengthening time between flare-ups. Regular, liberal use of emollients is recommended.

CONTEXT: Development of resistance in human pathogens against conventional antibiotic necessitates searching indigenous medicinal plants having antibacterial property. Twenty-seven medicinal plants used actively in folklore, ayurvedic and traditional system of medicine were selected for the evaluation of their antimicrobial activity for this study. Eleven plants chosen from these 27 are used as spices in local cuisine. OBJECTIVE: Evaluation of the effectiveness of some medicinal plant extracts against clinical isolates.

In the present scenario, pharmaceutical and biomedical sectors are facing the challenges of continuous increase in the multidrug-resistant (MDR) human pathogenic microbes. Re-emergence of MDR microbes is facilitated by drug and/or antibiotic resistance, which is acquired way of microbes for their survival and multiplication in uncomfortable environments. MDR bacterial infections lead to significant increase in mortality, morbidity and cost of prolonged treatments.

Preterm infants face many challenges in transitioning from the in utero to extrauterine environment while still immature. Failure of the preterm gut to successfully mature to accommodate bacteria and food substrate leads to significant morbidity such as neonatal necrotizing enterocolitis. The intestinal epithelial barrier plays a critical role in gut protection. Heat shock protein 70 (Hsp70) is an inducible cytoprotective molecule shown to protect the intestinal epithelium in adult models.

Some authors describe acute bacterial prostatitis as a self-limiting disease, and as with any other acute septic condition, parenteral broad-spectrum antibiotic therapy is indicated. Chronic bacterial prostatitis, however, is associated with a causative organism persisting unaltered in prostatic fluid and leading to relapsing urinary tract infections. In the 1970s, several workers produced a classification system and bacteriologic localization cultures for establishing the diagnosis of prostatitis.
