Description
Technical field
The invention belongs to beneficial bacterium screening technique fields, and in particular to a kind of movement Shandong outstanding person Salmonella bacterial strain and its application.
Background technique
Prawn culturing is important one of the sea-farming industry in China, brings huge economic benefit and society for China
Benefit.But with the intensive of prawn culturing, scale and high density production, disease problems become increasingly conspicuous.Vibriosis
(vibriosis) it is most common, the maximum bacterial disease of harmfulness in prawn culturing, has made multiple national by tight in the world
The economic loss of weight.The pathogen of vibriosis penaeus can be caused mainly to have Vibrio vulnificus (Vibrio vulnificus), molten algae
Glue vibrios (V.alginolyticus), Vibrio anguillarum (V.anguillarum), Kan Beishi vibrios (V.campbellii), magnificent arc
Bacterium (V.splendidus), kills prawn vibrios (V.penaeicida), vibrio parahaemolytious at beauty's vibrio piscium (V.damsela)
(V.parahaemolyticus) and Vibrio harveyi (V.harveyi) etc..Illness prawn shows as poor vigor, anorexia, growth
With metamorphosis process slowly, jejunum and the symptoms such as muscle is opaque, infect serious person's exhibit tissue and appendage necrosis, Er Qiechang
It is often accompanied by septicemia.In recent years, a kind of catastrophic emerging disease " Deaths syndrome " (early mortality
Syndrome, EMS) it was first appeared in 2009 in SOUTHERN CHINA, spread to Vietnam (2010), Malaysian (2011) again later
With the ground such as Thailand (2012).The disease occurs mainly in the young shrimp for putting seedling 20-30 days, can usually cause 100% after infected
The death rate.Estimate according to global aquaculture alliance (GAA), Asia prawn industry loses nearly 1,000,000,000 dollars because breaking out EMS.
Disease frequently significantly reduces the yield of prawn, forces people using antibiotic to treat disease.But
It is that antibiotic is to prevent it from growing or incite somebody to action by interfering the synthesis (such as cell wall, DNA and RNA) of pathogen essential elements
It is directly killed, and this mode will certainly cause strong selection pressure that bacterium is made resistance mechanisms occur, promotes antibody-resistant bacterium
Generate, thus caused by vicious circle so that problem is growed in intensity, the serious Green Sustainable for hindering culture fishery.It is logical
In normal situation, disease is since external environment deterioration causes prawn anti-adversity ability to decline, so as to cause pathogenic bacterial infection.
Therefore, the disease resistance for improving prawn is the key that solve the problems, such as.
In recent years, it is gradually accepted using the theory that beneficial bacterium carrys out prevention and control the farming disease harms.Fuller (1989) by its
It is defined as " a kind of viable bacteria additive of beneficial effect is played by improving host intestine colony balance ".This definition is to be directed to
For the mankind and livestock animals.Since aquiculture animal is lived in water body throughout one's life, surrounding water environment and autodigestion
Road is to maintenance body health no less important.Therefore, beneficial bacterium is defined as " by improving colony balance by Gram et al. (1999)
(in vivo or/and external) and a kind of viable bacteria additive for playing beneficial effect ".The mode that different beneficial bacteriums plays a role is not
Together, mainly include the following types: (1) generates digestive ferment, promote the digestion and absorption of food.Many beneficial bacteriums can generate amylase,
The enzymes such as protease enable the food for being difficult to digest in host gastrointestinal tract to digest.(2) attachment site and battalion are competed with pathogen
Support substance.Beneficial bacterium is colonized in enteron aisle and being adsorbed on intestinal mucosa, can prevent the attachment of pathogen, make it that intestines be discharged as early as possible
Road, referred to as competitive exclusion effect.(3) antibacterial substance is generated.Beneficial bacterium can generate some substances to inhibit other thin around
The growth of bacterium, such as bacteriocin, lysozyme and siderophore.(4) immunostimulation.Beneficial bacterium can stimulation of host generate it is thin
Born of the same parents are immune, the activity including improving lysozyme, respiratory burst, superoxide dismutase, antiprotease and peroxidase etc.,
Increase the quantity of leucocyte and lymphocyte；It can also promote the generation of antibody in host body fluids and cell.(5) nutrition is provided.Have
A little beneficial bacteriums can generate fatty acid, biotin and vitamin B12 etc., and supply host growth needs.(6) improve water quality.Some
Bacterium can convert organic matter to the gases such as carbon dioxide, the content of ammonia nitrogen and cultured water in water body be reduced, to mitigate
Water body burden.
The Antagonistic Fungi of screening pathogen is a kind of quickly and effectively means for obtaining beneficial bacterium, is especially come to marine bacteria
It says, antagonism is even more generally existing.The beneficial bacterium majority used in the past is from land or other water environments, due to life
Environment possibly can not incorporate purpose environment with locating microbiota difference, some beneficial bacteriums, to lose Tiny ecosystem adjusting
The effect of.Therefore, the drawbacks of can not playing a role because of environment discomfort can be reduced by screening indigenous beneficial bacterium, i.e., from purpose environment
Middle searching beneficial bacterium, reapplies in the environment, is conducive to that its microbial ecological is kept to balance.In addition, the use of beneficial bacterium is also
Can effective substitute antibiotics, improve food safety, promote the sustainable development of culture fishery.
