Characterization and antimicrobial susceptibility of Vibrio spp. Isolated from different environments

INTRODUCTION
The genus Vibrio consists of Gram-negative straight or curved rods, moving through a single polar flagellum. Vibrios are capable of both respiratory and fermentative metabolism. O2 is an acceptor universal electron, not denitrify. Most species are oxidase-positive. In most forms of vibrios are associated with enteric bacteria, but it share some properties with pseudomonads a well. The family Vibrionaceae is in the "facultative anaerobic Gram-negative Rods" in Bergey's Manual (1986) at the level of the family Enterobacteriaceae. In 2001 revisionist taxonomy (Bergey Manual), based on phylogenetic analysis, Vibrionaceae, Enterobacteriaceae and Pseudomonadaceae are landed in the Gammaproteobacteria. Enterics Vibrios are distinguished by being oxidase-positive and motile by means of polar flagella. Vibrios are distinguished from pseudomonas being fermentative as well as oxidative metabolism. Of the vibrios that are clinically significant for humans, Vibrio cholerae, the agent of cholera, is the most important.

Most vibrios have relatively simple needs of growth factor and grow on synthetic media with glucose as the sole source of carbon and energy. However, since vibrios are typically marine organisms, most species require 2-3% NaCl or sea water base for optimal growth. Vibrios vary in their versatility nutrition, but some species grow in more than 150 different organic compounds as carbon and energy sources, occupying the same level of metabolic versatility as Pseudomonas. In liquid medium vibrios are motile by polar flagella that are attached to a continuous coating with the outer membrane of the cell wall. Solid media can synthesize numerous lateral flagella are not sheathed.

Vibrios are one of the most common organisms in surface waters of the world. We present both in freshwater and marine habitats and in associations with aquatic animals. Some species are bioluminescent and live in mutualistic associations with fish and other marine species. Other species are pathogenic to fish, eels and frogs and other vertebrates and invertebrates. V. V. cholerae parahaemolyticus are pathogens of humans. Both diarrhea produce, but in ways that are completely different. V. parahaemolyticus is an invasive organism that affects the colon; cholerae is noninvasive, affecting the small intestine through secretion of an enterotoxin. Vibrio vulnificus is an emerging pathogen of humans. This organism causes wound infections, gastroenteritis or a syndrome known as "Primary septicemia."

METHODOLOGY
EXPERIMENT 1
Specimen Collection (Collins et al, 1973):
Marine samples were collected in different parts of the region of marine Rameshwaram (Palk Bay) at a depth of 1-2 m at various locations. The sewage and soil samples were collected GRD around campus.

EXPERIMENT: 2
2.1. Bacterial enumeration (Mary et al, 1985):
Number of cultivable aerobic heterotrophic bacteria present in water and sediment samples was determined by plating on marine agar and nutrient agar. For marine isolates, the media were prepared by sodium chloride 3.5% (NaCl). Then the plated were incubated at the appropriate time and temperature.

EXPERIMENT: 3
3.1. Isolation of Vibrio spp in water and sediment samples (Marie et al, 1985):
Different selective media used for isolation of Vibrio sp marine source. For marine isolates media were prepared by sodium chloride 3.5% (NaCl). The media used for isolation of Vibrio sp are: 1. Thiosulfate citrate bile sucrose agar (3.5% NaCl) 2. Marina agar medium enterprises;

EXPERIMENT 4
4.1 Identification
Microscopy: Gram staining characteristics and cell morphology was determined by standard methods (Gerhardt et al., 1981). Motility was observed under the microscope in fresh.
cultural characteristics: morphology of the colony of different isolates of Vibrio sp were observed in nutrient agar thiosulfate citrate bile sucrose agar (TCBS), blood agar, Mac Conkey agar, mannitol salt agar and results were tabulated.
Physiological characterization: preliminary physiological characterization of catalase as evidence, proof of the hydrolysis of starch test indole, MRVP test, citrate test, oxidase test, string test, proof of the fermentation of carbohydrates (sugars used in sucrose, lactose, glucose, maltose, mannitol), cholera red reaction was carried out and the results were tabulated.

EXPERIMENT 5
Anti-microbial susceptibility testing Kirby-Bauer method
Procedure:
1. Suspend a case of bacterial culture turbidity of rehearsing.
2. Place a sterile cotton swab in the bacterial suspension and remove excess liquid by pressing and turning the cotton against the inside of the tube above the liquid level. The swab is streaked at least in three directions on the surface of Mueller-Hinton agar and TCBS agar to obtain uniform growth. A final sweep is made around the edge of the agar. Make sure the line of confluence.
3. Let plates dry for five minutes.
4. Using sterile forceps, discs, including the following antibiotics at the plate: penicillin G, ampicillin, cephalothin, erythromycin, tetracycline, methicillin, streptomycin and other appropriate antibiotic discs.
5. Incubate plates at 15 minutes after applying discs. Plates must be incubated soon after placing the discs as the test is standardized in conditions to start the spread of antibiotic and bacterial growth at approximately the same time.
6. After overnight incubation, measure the diameter of growth inhibition zone around of each disc to the nearest whole mm. Carefully examine the plates for the well-developed colonies within the zone of inhibition.
7. Use a table of sensitivity antibiotic to determine whether the strain is resistant, intermediate or susceptible to the antibiotics tested.

RESULTS AND DISCUSSION
Totally 35 samples were collected in different locations of the marine region, garden soil, domestic sewage and bacteria are gram-negative halophilic water.Vibrio large measure. Vibrio is rod-shaped, and may be straight or curved. They are mobile organisms, using a single polar flagellum to travel. Vibrios are one of the most common organisms surface waters in the world. They occur in both marine and freshwater habitats and in associations with aquatic animals. Some species are bioluminescent and live in associations mutual fish and other marine species. These samples were processed through the procedures commonly used as selective media (listed below), staining Gram, fresh observation of motility and bio-chemical tests including catalase test, starch hydrolysis test, indole test, test MRVP, test citrate, oxidase test, string test, proof of the fermentation of carbohydrates (sugars used as sucrose, lactose, glucose, maltose, mannitol) cholera red reaction is carried out and the results were tabulated for the identification of Vibrio sp of the above examples, and can be processed, the details of description, as shown

COLONY MORPHOLOGY of Vibrio sp.
Media details
Nutrient agar moist, translucent, regular, in the form disk, 1-2mm in size, bluish tint can be seen in the light transmitted as the distinctive color
Mac Conkey agar colonies after prolonged incubation colorless colonies pink is observed. (Plate: 2)
Blood agar colonies were surrounded by a zone of hemolysis
Thiosulfate citrate bile salt agar colonies are yellow due to fermentation.
Mannitol salt agar No significant growth was observed.

The morphology of the colonies of the Vibrio strains was variable during isolation on selective media. The colonies were very clear, moist, disc-shaped colonies of yellow and pink were observed from different sources. Culture mother was sub cultured in the same media for the maintenance of culture. All Vibrio strains isolated were numbered for easy identification and convenience. reaction Gram staining was recorded by the heat fixed smears of vibrio culture. Mobility and cell shape were determined by direct observation of wet mounts fresh culture broth by microscopy. The Vibrio on TCBS chacteristics half shows that most of the isolates were mobile and able to produce pigment yellow and green. Thiosulfate-citrate-bile salts-sucrose (TCBS) agar (Difco) is a selective medium used to isolate members of the genus Vibrio estuarine environments. The high thiosulfate and citrate concentration and strong alkalinity of the medium greatly inhibit the growth of Enterbacteriaceas. Oxbile and cholate suppress primary enterococci. Any bacteria coliforms, which can grow, can not metabolize sucrose. Only a few strains of sucrose of the protease can grow from yellow, vibriod as colonies. The mixed indicator thymol blue, bromothymol blue changes its color to yellow when acid is also formed in this way strongly alkaline
Out of 35 different samples collected, samples only 17 showed the presence of Vibrio sp, most marine samples collected from different marine regions shows positive results for Vibrio sp, when compared with other samples such as sewage water and soil samples. And in the case of the sample of domestic water (tap water and mineral water) showed no strain Vibrio. Vibrios are inhabitants of aquatic environments. Humans can become infected, causing intestinal or extraintestinal diseases. The most prevalent diseases caused by vibrios are those who are well informed, including cholera and other forms of acute gastroenteritis. There may be many other diseases that vibrio- not reported some of the determinants of virulence of Vibrio spp. are well characterized.

Looking at the results of tests, most of the tests were considered positive for Vibrio isolated cholerae.The were positive for Vibrio cholerae were mainly isolated from marine environment, compared with other samples such as sewage and soil samples. Through this result showed that Vibrios are inhabitants of aquatic environments. Marine animals can harm humans in several ways. Some animals cause injury by induction of the infection. These infections occur when oral bacteria are introduced into the tissues of victims who have been bitten. Bacteria in marine animal tissues can cause infection when ingested. Besides, the sea water contains bacteria, so the skin and exposed soft tissue injuries Sea water can become second injection.

Kirby-Bauer disk diffusion method: Antibiotic susceptibilities disk
Most isolates of the marine source of high incidence of antibiotic resistance was evident against amoxicillin, ampicillin, cefuroxime and followed by rifampicin Carbencillin and streptomycin on the ground and wastewater samples. However, it was less antibiotic resistance against chloramphenicol, tetracycline, penicillin G, Nalidixicacid, Sulphafurazole Gentamicin, Trimethoprim, Neomycin and Amikacin. This may be due to the fact that terrestrial bacteria in sea water into antibiotic resistant plasmids may be responsible for the prevalence of resistance genes in the marine environment. However, there are not many publications available to acquire resistance to ampicillin against (68%), cefuroxime (66.7%), amikacin (55%), kanamycin (58.8%) and trimethoprim (76.7%) in sarba aurata in China. One can assume that anthropogenic factors (Hospital effluents) may have influenced the acquisition of resistance in Vibrio species, due to these antibiotics, since there are no available reports on the use of these drugs for aquaculture in India. However, the results of this study will provide baseline data for future research on the degree of resistance to antibiotics, which can manifest itself through the isolation of plasmids, the efficiency of transformation and conjugation experiments. Results of the impact resistance to multiple antibiotics in Vibrios may improve our understanding of drug-resistant strains and their effects on the future therapy of shrimp and and human diseases. Therefore, the unscrupulous use of antibiotics against diseases should be avoided and the restrictions on the use of antibiotics can be implemented by a national policy of antibiotics for India.
