1. INTRODUCTION
Multiplex PCR is a techniques by which we can identify particular gene of any bacteria, any
cells or any type of organism by targeted their gene with with the specific primer, in this
technique we can use multiple of DNA and can amplify each DNA with multiple of primers at
one time to rapid identify multiple of organism from gien population of samples! "raditionally,
detection and enumeration of bacterial pathogen hae been largely based on the use of selectie
culture and standard biochemical method(Kong et al,).#ut these methods suffer from numbers
of drawbac$s% &irstly, Pathogenic bacteria which normally occurs in low numbers tend to incur
large number of error in sampling and enumeration (Fleisher JM). 'econdly, culture based
method are time consuming, tedious, inariably monospecific (i!e! detecting low output)!
"hirdly,many pathogenic organism in the enironment although iable, are either difficult to
culture or non%culturable (Fleisher JM), but can still cause illness (Rahman et al ,1996). Due to
this difficulties, examination of water samples for pathogens li$e vibrio cholerae, shigella
dysenteriae, aeromonas spp. and campylobacter spp.,etc! is normally not performed during
routine microbiological assesment of water quality (Kong et al,). "he aim of this study is to
screen different water bodies (tap water,pond water, rier water and fish water) for the presence
of ibrio species and determine their pathogenicity! "he $nowledge will help to control ibrio%
associated gastroentritis in india as the awareness of the danger associated with the consumption
of tap water, raw and undercoo$ed seafood will be created for the masses! Vibrio are gram%
negatie, straight,cured rod,non spore forming,motile,usually contain single polar flagellum
and halophilic,few species are non%halophilic those who are halophic they require salt
medium(Nacl) for their growth! Mostly are sensitie to acidic p*,and few are al$aline p*
tolerant! According to centre of disease control +, infection and - death happens in each
year by ibrio infection! "ill now date ibrio hae ./ species all around the world, out of ./
twele account for the ma0ority of ibrio infection in humans!ibrio are water surface organism
occurs in fresh water as well as salt water(rier,pond,fish and industrial effluent etc!!) they are pathogen of marine liing organism,this is the reason that doctor suggested do not to eat
uncoo$ed food (fish,lobster,crac$) becouse comsuming of uncoo$ed food is the indirect
pathway of ibrio to enter inside the human body!

ampbellii,V.diabolicus,V.fischeri,V.furnissii,V.tapetis V.hollisae, V.damsela and many more
species li$e this are human pathogen! Most of this species secrete enterotoxins in foods,water
and gastrointestinal tract! 1dentification of ibrio species is ery important for us becouse this
are the main cause of human infection! 1f we could identify that water bodies which are
contaminated by ibrio so that we can ma$e them free from pathogens and preent to cause any
water born disease again!
A multiplex polymerase chain reaction (PCR) method,specifically designed for application in
routine diagnostic laboratories, was deeloped for identifying 2 human pathogenic Vibrio
species: V.cholerae,V.parahaemolyticus,V.vulnificus,V.alginolyticus,V.mimicus! "his assay
directed toward the dna3 gene ( a house$eeping gene that encodes heat shoc$ protein 4,for the
identification of ibrio species) was tested on the total of 5+ strains representing /5 ibrio
species! 'pecific PCR fragments were formed in isolates which belong to the 2 target species
and were absent from all strains other than this 2 species, indicating high specificity of multiplex
PCR! "his technique represented a rapid detection of the 2 ma0or pathogenic ibrio species!
Most of the effort for ibrio identification were done with marine water, Now the present study
based on rapid identification of ibrio species form marine water as well as fresh water!

epidemiological studies!
5osies2il et al .(+314) described about the application of the PCR method for the
simultaneous detection of DNA of 7ram%negatie bacteria, 7ram%positie bacteria, yeast fungi
and filamentous fungi in blood and, thus, a whole range of microbial etiological agents that may
cause sepsis! Material for the study was sterile blood inoculated with four species of
microorganisms ( Escherichia coli, Staphylococcus aureus, Candida albicans and Aspergillus

method is based on nested%multiplex real%time PCR !Analysis of the obtained data shows that
sensitiity of nested%multiplex real%time PCR remained at the leel of 99 C&=ml for each of
the four studied species of microorganisms and the percentage of positie results of the
examined blood samples from the patients was .8 and 9@8 for the microbiological culture
method! "he designed primers correctly typed the studied species as belonging to the groups of
7ram%positie bacteria, 7ram%negatie bacteria, yeast fungi, or filamentous fungi! Results
obtained by us indicated that the designed PCR methodsB (9) allow to detect bacteria in whole
blood samples, (/) are much more sensitie than culture method, (5) allow differentiation of the
main groups of microorganisms within a few hours!
Kama et al .(+314) reported that microscopy and antigen detecting rapid diagnostic tests are
the diagnostic tests of choice in management of clinical malaria! *oweer, due to their
limitations, the need to utili:e more sensitie methods such as real%time PCR (qPCR) is eident
as more studies are now utili:ing molecular methods in detection of malaria! 'ome of the
challenges that continue to limit the widespread utili:ation of qPCR include lac$ of assay
standardi:ation, assay ariability, ris$ of contamination, and the need for cold%chain!
?yophili:ation of molecular assays can oercome some of these limitations and potentially
enable widespread qPCR utili:ation! A recently published multiplex malaria qPCR assay was
lyophili:ed by free:ing drying into 'ample%Ready format (MM'R)! MM'R assay contained
all the required reagents for qPCR including primers and probes, requiring only the addition of
water and sample to perform qPCR! "he performance of the MM'R assay was compared to the
non%free:e dried, EwetF assay! 'tability studies were done by maintaining the MM'R assays at
four different ambient temperatures of 4GC, room temperature (R"), 5.GC and 4/GC oer a
period of 4/ days, tested at seen%day interals! Plasmodium falciparum and Plasmodium iax
DNAs were used for analysis of the MM'R assay either as single or mixed parasites, at two
different concentrations! "he C" alues and the standard deiations ('D) were used in the
analysis of the assay performance!"he limit of detection for the MM'R assay was !/44

clinical samples, MM'R assay performed with 98 sensitiity and specificity compared to the
EwetF assay!"he MM'R assay has the same robust performance characteristics as the EwetF
assay and is highly stable! Aailability of MM'R assay allows flexibility and proides an option
in choosing assay for malaria diagnostics depending on the application, needs and budget!
5a*ier et al .(+314) obsered that :ymoseptoria tritici is a hemibiotrophic ascomycete fungus
causing leaf blotch of wheat that often decreases yield seerely! Populations of the fungus are
$nown to be highly dierse and poorly differentiated from each other! *oweer, a genotyping
tool is needed to address further questions in large collections of isolates, regarding regional
population structure, adaptation to anthropogenic selectie pressures, and dynamics of the
recently discoered accessory chromosomes! Procedure is limited by costly and time%consuming
simplex PCR genotyping! Recent deelopment of genomic approaches and of larger sets of
''Rs enabled the optimi:ation of microsatellite multiplexing!A reliable protocol to amplify /4
''Rs organi:ed in three multiplex panels, and coering all J! tritici chromosomes! Ie also
propose an automatic allele assignment procedure, which allows scoring alleles in a repeatable
manner across studies and laboratories! All together, tools enabled us to characteri:e local and

for each locus in turn were added indiidually in subsequent amplifications until m%PCR was
achieed! Amplicons of the expected si:e were obtained from each of the four bacterial gene
fragments! &inally, the analytical specificity and limits of detection were tested! #ecause they
did not amplify any product from non%'"1 tested species, the primers were specific! "he
detection limits for the Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma hominis
