In concluding this discussion, the quorum sensing is wider spread among bacterial population then was previously thought, (In Gram positive, Gram negative bacterial communication). Current assays for antimicrobial activities are inadequate because some antibiotic producing bacteria may require the presence of another bacterial species. These findings have important implication for the discovery of novel antimicrobial compounds from marine bacteria and may allow the development of new methods for screening novel compounds active against multidrug resistant bacteria.

Be as Honest as the Day is Long This isn't a trite clich; but rather it's a clich that offers words to live by on a multitude of levels. Lies are insidious in that they must be fed by more even lies in order to be successful. Unless you plan on carrying around a notebook to keep track of all your fibs, white lies and down right untruths, it's best to just live your life honestly, which is after all, the best policy.

To put it bluntlyIm going to be frank, nobody likes being dumped and few of us take pleasure in being the "dumper" either. The end of any relationship, often inspite of its length, will be a traumatic time for both parties involved where your emotions run rampant. Understanding, compassion, patience and especially, honesty, are the key factors in any successful break up, if there even is such a thing. You must learn how to let go of any relationship that you no longer wish to take part in, while preserving your dignity along with theirs.

RESULTS AND DISCUSSION: QUORUM SENSING/CROSS SPECIES INDUCTION ANALYSIS In the present investigation totally 54 isolates were collected out of seaweed species. Among 54 isolates, 17 of them are producer strain, another 17 are the inducer strain rest of 20 isolates is normal and not showing any signs of activity (Table.2).

All the above mentioned biochemical tests were performed by following standard methodology given in the Microbiological Laboratory Manual by James 3.Cappuccino (1999).

The results of Vanderivere and Kirchman 1993 suggest that the addition of increased surface by adding sand will induce the exopolymer synthesis through the high cell density dependent system. In the same way the bacterial organisms attached to the surface of seaweed shows alteration of genes expression may be due to the response to the high competitive environment. When cell density increases the competition for space and nutrients are also increased. So the existing bacteria were forced to protect themselves in this competitive environment. Normally in this condition the bacteria will be activated to induce the expression of certain hidden genes in genetic material through quorum sensing. The quorum sensing is principles were active compounds (autoinducer) from bacterial cell will promote the expression of a particular hidden gene of other bacterial organism in a stressed condition.

Scientists have been paying close attention to swingers and the development of online swinging communities. They've made extensive research and discovered that swinging can improve relationships, helping people to communicate more freely and be more honest. Not only that people who explored swingers ads and met with some members felt a lot happier, but they declared that their lives are now more exciting and that includes the sexual part. For many couples, engaging in swinging activities with the help of the Internet has been more than they could wish for. The channels of communication were open and they both felt more confident in their sexual nature than before. Online swinging clubs have definitely their merit, especially since they don't judge and tell. They just offer a free-judgment environment for people who are not shy to explore their deepest sexual fantasies and show how far imagination can reach. It is all about sexual attraction in the end and enjoying the very sexuality that we have been gifted with.

This experiment does not showed any inhibition zones Bacterial identification The 3 producer and 3 inducer strains which were responded the quorum sensing principles alone were subjected to biochemical analysis for identification. The obtained results revealed that all the producer strains showed sings of Pseudomonas sps and the inducer strains showed signs of Vibrio sps. So, based on the obtained result all the producer strains seems to be a Pseudomonas sps where as all the Inducer strain belongs to the genus vibrio.

In this experiment among 17 Producer and Inducer strains only 3 of them have responded to the quorum sensing principle. (BrB+/BrB-), (GcC+/GcC) and (SA+/SA-)

Swinging is mainly the experiencing of something different. It is about the skin, the smell and the touch of a completely new person against yours. It is all about breaking stereotypes and transforming sexual fantasies into true realities. Swingers are not interested in making their sexual preferences known to the whole world; they maintain complete discretion and prefer to use the Internet to find people who can fulfill their desires.

BACTERIAL IDENTIFICATION The organisms responded to the quorum sensing process alone were identified by the following biochemical analysis.

Starch hydrolysis test, Protein hydrolysis test, Lipid hydrolysis test, Oxidative / Fermentative test, Salt concentration (0%, 3%, 5%, 7%, 10%), TCBS, Growth in Temperature, 42??C and 47??C

In this present work the totally 54 isolates were screened from 20 different seaweed species out of which 34 species were showed the signs of quorum sensing i.e. 17 producer and 17 inducer strains, but when these organisms where subjected to quorum sensing principle in mixed culture only 3 them have responded. So the present study reveals around 17% of bacterial species isolated from seaweeds and sediment were responded to quorum sensing. According to the results of bacteria isolated from marine algae surfaces indicated that the incidence of antibiotic producing strains from this habitat was 20% where as that from sea water was only a few percent. In the present study also reveals more or less the same ratio in Pseudomonas spp. was observed. Our results also reveals a results of Kell et al., 1995; Stead et al., 1996; they have said the culture supernatant of Pseudomonas sps known to contain AHLS which induces the production of phenazine antibiotics. In this investigation due to time constraint, It was not attempted to identify the active compound secreted by Pseudomonas through quorum sensing, which may leave the space for the further intensive research in future.

ABSTRACT Bacterial biofilms are sessile communities with high cell density that are ubiquitous in natural, medical, and engineering environments; they are fascinating since they are primitive tissues with an advanced chemical communications network. Currently, there is an explosive amount of biofilm research, most of it with the ultimate aims of biofilm prevention, control, or eradication.The present investigation was aimed to study the cell signaling principle among seaweed epibiotic bacterial organisms , totally 54 bacterial isolates were made out of 20 seaweed species. Among 54 bacterial isolates 17 of them producer, another 17 of them inducer strains rest of 20 isolates were normal that have not showing any signs of activity. The 17 producers and 17 inducer strains were subjected to the cross species induction by quorum sensing principle and found that only 3 of them have responded to the cross species induction in production of antibacterial compound against the respective inducer strains. All the 3 producers and inducer were identified by biochemical analysis and surprisingly that all the 3 producer strain belongs to Genus Pseudomonas and inducer strains were belongs to Genus Vibrio. The supernatant obtain from mixed culture of Pseudomonas & Vibrio shows the antibiotic activity against the various Vibrio species which were isolated from other sources. Such as Vibrio from primary film, Vibrio from sediment Vibrio from seaweeds epibiotics. The obtain results clearly shows the particular Pseudomonas from seaweed epibionts has the capability of producing potential antibiotic compound against wide range of Vibrio species through quorum sensing.

Is attraction a matter of chemistry? Maybe. According to scientists, the attraction between animals of the opposite sex is all about chemicals called pheromones. The effect of pheromones in behavior of insects is the most studied to date. It has been observed, at least in some experiments, that pheromones are responsible for communication among same species and colony of ants. The horrible odor released by skunks to ward off enemies is said to be a kind of pheromone. Some species of apes rub pheromone-containing urine on the feet of potential mates to attract them.

We suggest that the above said mechanisms in Pseudomonas with quorum sensing principle might have occurred in the present study also. This induces the bacteria Pseudomonas in epibiotic seaweeds to secrete certain active compound against to the competitor Vibrio species.

Scientists believe that animals (usually the females) such as insects and mammals send out these chemical signals to tell the male of their species that their genes are different from theirs. This gene diversity is important in producing offspring with better chances of survival. The perfume industry has capitalized on pheromones as a means to increase one's sexual attractiveness to the opposite sex. Animals such as the whale and the musk deer were hunted down for these chemicals.

The collected seaweed samples were thoroughly washed with sterile seawater to removes the loosely attached bacteria/particles. Seaweed fronds were scrubbed with sterile cotton swabs to obtain epiphytic bacteria. Epiphytic bacterial organism in the swab were inoculated in sterile peptone broth (50% sea water) and incubated at 28??C in an incubated shaker (220 rpm / min) for overnight. After the incubation period the enriched cultures were serially diluted up to 10-8 concentration and 200 microlitre of each diluted samples were transferred into the nutrient agar plate (50% sea water). The plates were incubated at 28??C for 5 days and the plates with crowded colonies were selected. In the crowded plates those colonies, which showed the sign of inhibition zone around its margin to the neighboring colony, were selected and considered as producer strain. The neighboring sensitive colonies were treated as inducer strain. Both producer and inducer strains were streaked repeatedly until to get pure culture. The pure culture were properly labeled and subjected to the quorum sensing analysis.

Lately, scientists are looking into the existence of human pheromones and its role in mate selection. There are many conflicting views in the realm of biology, chemistry, genetics, and psychology. Most scientists would assert that these do not exist, or if they do, do not play a role in sexual attraction between a man and a woman. But new researches such as that conducted by Swiss researchers from the University of Bern led by Klaus Wedekind are slowly making these scientists rethink their stand. Their experiment involved women sniffing the cotton shirts of different men during their ovulation period. It was found out that women prefer the smell of men's shirts that were genetically different, but also shared similarities with the women's genes. This, like in the case of insects and other mammals, was to ensure better and healthier characteristics for their future children. But researchers also cautioned that preference for a male odor is affected by:

Does personality figure in sexual attraction? Yes, but so does your perception of a potential mate's personality. According to a research conducted by Klohnen, E.C., & S. Luo in 2003 on interpersonal attraction and personality, a person's sense of self-security and at least the person's perception of his/her partner were found to be strong determinants of attraction in hypothetical situations. What does this tell us? We prefer a certain personality type, which attracts you to a person. But aside from the actual personality of the person, which can only be verified through close interaction through time, it is your perception of your potential partner that attracts you to him/her, whether the person of your affection truly has that kind of personality or not. This could probably account for a statement commonly heard from men and women on their failed relationships: "I thought he/she was this kind of person."

So should I stop trying to become attractive? More than trying to become physically attractive, work on all aspects of your health: physical, emotional, mental, and spiritual. Physical attraction is still a precursor. Remember, biology predisposes us to choose the partner with the healthiest genes. Where your emotions are concerned, just ask this to yourself: would you want to spend time with a person who feels insecure about him/herself?

MATERIALS AND METHODS: SAMPLE COLLECTION: Seaweed samples were collected from Gulf of Mannar Marine Biosphere Reserve and identified up to species level by using CMFRI bulletin (14) as follows:

In gram positive bacteria peptide and derivative peptide based signaling molecules seem to be the predominant mode of communication. During high cell density the marine bacteria can produce enzymes, surfactants, toxins, and antibiotics by the chemical signal communication. Marine epibiotic bacteria are also known to produce compounds active against drug resistant hospital pathogen by the cross species induction method. Building on assays described by Austin (Billaud and Austin 1990) a screening procedure has been developed in which marine bacteria are challenged by exposing them to terrestrial bacteria prior to assay of antimicrobial compounds. Hence in this present investigation it is proposed to find out the ability of sea weed epibiotic bacterial organism to produce antibacterial compounds through quorum sensing.

Don't Become a Puppeteer Worse than silly clichs and excuses are when you're strung along like a puppet for months or even years on end while the other person decides on how to end it. Imagine how they'd feel knowing you wanted it over for a while now but just didn't have the guts or the gumption to actually do it? Drawing things out only create drama and even more hurt feelings. Quick and painless is always better than a slow, agonizing end to a relationship that's long been over.


The adventure and the thrill offered by swinging escaped can help couples rediscover passion without the fear of cheating. Swingers ads are not just for heterosexual couples; they are open for everyone, bisexuals, gay or lesbians. What they are trying to point out that the sexual status is not as important as the exploring sexual fantasies. What is important is that the sense of excitement and opportunity to put dreams into reality can help one reach the highest peaks of pleasure. All with the help of the Internet and online swinging communities!
