1.6 trial tests and the determination for attacking toxic dose
Before formal test, the 3 age in days healthy chicks for raising with field and raising under the same conditions are chosen, are connect by document is oral Kind pathogenic strain, determines the minimal lethal dose MLD(10 of pathogenic strain9CFU/ is only).
Salmonella virulence prerun, takes a small amount of bacterium solution, makees 10 times of bacterium solutions for being diluted to various concentration with physiological saline, respectively It is the 10 of stoste and stoste-1、10-2、10-3Concentration takes the close chicken of weight 50, is divided into 5 groups, every group 10, take orally respectively with On not same amount or the bacterium solution of various concentration, observe chicken morbidity and death condition in 5d and record;The minimum lethal agent of 5 days animals (MLD) is measured as this test and attacks toxic dose.
1.7 inoculum concentrations and bacterial population
Every chicken oral vaccination 1 × MLD salmonella bacterium solution.
1.7 dosages, the course for the treatment of and method
Each prevention group 12h before inoculation carries out preventive administration;When there is first morbidity chicken after inoculation in treatment group Start to offer medicine;Infection control group fed does not add the basal diet of any drug;Healthy control group isolated rearing, does not appoint Where reason.Freely drink cooling sterilizing ordinary water after boiling;The equal successive administration of each group 5 days, observation period are 8 days after inoculation.It gives Pharmaceutical quantities, method are shown in Table 1.
1.7 index of assessment of curative effect
1.7.1 clinical observation
After animal inoculation pvaccination, in 1~8 day, clinical symptoms are observed day by day, and the state of mind, breath state, excrement, hind leg are closed Section, amount of drinking water, feed intake etc. are observed, and carry out pathology dissect, bacterium separation identification to the chicken that dies of illness, and acquire chicken reality of dying of illness Matter organ carries out the items contents such as pathological tissue observation and is tested, and observes and records test result.
1.7.2 the death rate
All to be prevented within experimental period or treatment is invalid, there is salmonellosis classical symptom and death in clinic, through cuing open Cubing typical case's salmonellosis lesion characteristics, bacteriology separation, are accredited as positive, and it is dead to be determined as infection.According to death toll Calculate each group death rate.
1.7.3 efficient
After the test, the percentage of test group is accounted in each group surviving animals as effective percentage.
1.7.4 cure rate
After medication, animal is without exception or restores normal, and no clinical symptoms person is to cure.It is controlled according to number calculating each group is cured More rate.
1.7.5 feed intake
Each group feed intake is calculated with the difference of filling amount and surplus doses, and each test group is counted, it is average to obtain each group chicken Feeding grain.Calculation formula is as follows: each group average daily gain (g)=(filling amount-remains doses)/number of animals
1.7.6 body weight increase rate
With the calculating of the ratio between the average weight gain of infection experiment group and the average weight gain of healthy control group, calculation formula is as follows:
1.7.7 the separation and identification of bacterium
Separation identification is carried out to bacterium by following check problem:
Sampling → Zengjing Granule → identification culture → biochemical investigation → serological test → result report.
1.7.7.1 acquisition and the Zengjing Granule of sample
The tested dead chicken of dissect, sterile separation simultaneously acquire liver blood, painstaking effort or ascites.Select broth medium and chlorine Change magnesium malachite green bouillon (MM) culture based on Zengjing Granule 18 at 37 DEG C~for 24 hours, bacterium solution set 4 DEG C of refrigerators save it is to be checked.
1.7.7.2 identify the biochemical test of culture with bacterium
A small amount of Zengjing Granule bacterium solution is dipped with oese, streak inoculation is on XLD agar plate, Mai Kangkai culture medium.In 37 DEG C of culture 18h~for 24 hours, observation colony characteristics (it is recommended that morphological feature of description bacterium colony).Then, divide from XLD agar plate Other picking meets 2 of salmonella cultural characteristic or more suspicious bacterium colonies, is seeded on triple sugar-iron-agar medium, first on inclined-plane Scribing line is punctured then at bottom;Then it in the case where unsterilised after transfer needle inoculation, continues directly to be inoculated in lysine decarboxylase Inoculated and cultured on test medium, 37 DEG C of culture 18h~for 24 hours, observe the growth characteristics of bacterium colony.It records and reports result.
Doubtful positive strain culture solution is carried out to biochemical identification, record in VITEK-2 full automatic microorganism analysis system As a result.
1.8 data analysis and process
Selecting statistical software is that SPSS15.1 is for statistical analysis to data.The death rate, efficient chi-square criterion, weight gain are used F is examined.
2. result
2.1 clinical effectiveness
Gradually appear different degrees of typical white scour of chicken clinical symptoms after Chickens Infected after 4h~8h, after 8h, chicken Occur dead.Clinical disease one's own judgment: spirit is depressed or tired, and individual chicken pains pipe, and drinks loss of appetite, and loose random is exhaled It inhales speedup, wheeze, both wings are sagging, and eye closing lethargic sleep, chilly gathers, and are reluctant to walk about, and draw white or green slurry shape loose stool, anus attached Close or periphery faecal contamination, or stick white excrement blocking chick anus, chick group are often accompanied by sad and shrill shriek, in cage tool Moist filthy, packing paper humidity has obvious loose stool.
Dead chicken pathology dissect major pathologic features are: liver hyperemia enlargement, being dispersed in property necrosis point, congestive heart, There is intoxicated junket sample tubercle in hydropericardium, empsyxis or hyperemia, enteric hemorrhage, seroperitoneum, later period individual chick hearts, and hind leg closes Save enlargement.Yolk malabsorption includes cheesy object, and intestinal mucosa falls off, and has a large amount of mucus shape whites to stagnate object in cloaca, There are a large amount of mucus in oral cavity.From separation of bacterial such as liver, abdominal cavity, hearts, it is possible to identify infected for Salmonella.
Healthy control group chicken is during test without relevant clinical syndrome.
2.2 preliminary result
Preliminary result see the table below:
Table 2 attacks 5 days animal dead situations after malicious Salmonella pullorum
Table 2 the result shows that: the MLD of malicious chick is attacked through gastrointestinal tract as 0.25ml × 6.75 × 10 with the bacterial strain9A/L.
The disease incidence of 2.3 each test groups, the death rate, effective percentage, cure rate, weight gain, feed-weight ratio statistical result table.
The curative effect situation * of each test group of table 3
Note: data shoulder marking-up mother is identical in table, indicates that there was no significant difference (p > 0.05);Conversely, significant difference (p < 0.05/0.01)
As shown in Table 3, intestines bacterium dissipates clearly the prevention for the white scour of chicken, middle dosage and high dose and the positive group of infection and low Significant difference (p < 0.05/0.01) is deposited between dosage group;Its prevention morbidity effect is suitable compared with positive drug control group, morbidity Rate is without significant difference (p > 0.05).The death rate also shows similar result.I.e. high middle dose group, the chick of positive drug group are dead Rate is died, it is lower compared with low dose group and infection control group, have significant difference (p < 0.05/0.01);Prevention administration obtains healing Rate table 3 is shown: prevent the chick of high dose group in dissipating clearly to intestines bacterium, cure rate relatively infection positive controls when off-test and Low dose group is high, has significant difference (p < 0.05), but lower compared with positive drug control.
Table 3 is also shown: intestines bacterium dissipates clearly for treating the white scour of chicken, the death of high middle dose group, positive drug control group Rate is lower, has significant difference (p < 0.05) compared with low dose group, infection positive controls.Cure rate on the 5th is also higher, with sense Dye control group and low dose group are compared, and are had significant difference (p < 0.05).But it is lower than positive drug group (p < 0.05).
To sum up experimental result prompts, the prevention and treatment that can be used for the white scour of chicken scattered clearly of intestines bacterium, under high, middle dosage Activity is suitable with positive Antibiotics drug, shows in the prevention and treatment for the white scour of chicken, intestines bacterium clears can replace entirely clearly For antibiotic usage.
2.4 death separation of bacterial identification results
By dead diseased chicken dissect, sterile coring blood, liver blood or abdominal cavity ascites culture and identification culture, result are as follows:
4 dead animal bacterium of table is separately cultured and identification result
As the result is shown: it is significantly high that salmonella death chicken separates positive rate infected group, low dosage intestines bacterium medication group scattered clearly In middle dosage, high dose medication group and positive drug control group.It is further noted that: either intestines bacterium dissipates medication group also clearly It is to there is different animals to divide in the painstaking effort of dead chicken, liver, lung or abdominal cavity in the dead chicken of positive drug control group Bacterium is separated out, through Preliminary Identification in addition to the salmonella for thering is infection to attack poison, there are also Some Animals ehec infection, lethal original Because that may have certain relationship with the secondary infection of Escherichia coli except having outside the Pass with salmonella infection.
2.5 death histopathologic slides analyze result (see Fig. 1~6)
To all groups die of illness chick acquire the heart, liver, spleen, lung, caecum carry out pathology section examination.Control group chick exists It cuts open within 6th day and above-mentioned tissue is taken to carry out sections observation after killing.
As the result is shown: morbidity chick shows the pathologic processes such as inflammation, bleeding, extravasated blood, denaturation, the necrosis of each tissue.Its In it is the most serious to infect control group chick pathological change of dying of illness.And intestines bacterium dissipates clearly middle dosage, the high dose control group of control group Die of illness chick, overall pathology section examination, and basic pathology change procedure and the infected group chick that dies of illness are similar.But it can see Out, relatively slight in the degree of pathological change, and individual tissues have rehabilitation after apparent inflammatory process to show.Certainly, therein The lesion tissue of positive drug control group prevention group is the slightest.Thus as the result is shown: although dissipating prevention clearly using intestines bacterium and controlling Treat the death that the white scour of chicken is still likely to occur chick.But there is basic pathology process caused by pathogenic bacteria lighter.In fact from when death Between and the death rate also obtained corresponding evidence.Intestines bacterium, which dissipates clearly, has certain suppression to pathologic process caused by mitigation salmonellosis Production is used.And preferable preventive and therapeutic effect thus can be played to the prevention and treatment white scour of chicken.
3. discussion and conclusion
3.1 Salmonella pullorum diseases (pullorum disease), abbreviation white diarrhea is by Salmonella pullon The infectious disease that caused various age chickens often send out.This disease not only brings serious harm to poultry husbandry, results in significant economic losses, And S. pullonum can be colonized in poultry intestinal tract, polluted egg or when processing poultry ketoboidies, polluted chicken, after And enter human foods chain, become the potential source of mankind's salmonella infection.So pass of the prevention and treatment of white diarrhea by people Note.
In recent years, some chicken disease experts think that white diarrhea should be listed in the first place of chicken disease.Studies have found that 1~4 day in recent years Age day old chick disease incidence increased significantly, and the chicken morbidity and mortality within 2 week old are all very high.It is brought sternly to poultry husbandry The harm of weight.Although antibiotic, antibacterials, such as clinically common cephalosporins semisynthetic antibiotics, aminoglycoside Antibiotic, tetracycline antibiotics, fluoroquinolones antimicrobial DP finish, disulfonamide etc. have certain effect to the disease is prevented and treated Fruit can effectively reduce the morbidity and mortality of white diarrhea.But as treatment be not thorough and long-term Irrational Use of Drugs caused by The increase of antibody-resistant bacterium increases the difficulty for preventing and treating the disease.In addition drug resistance salmonella and salmonella and Escherichia coli it Between drug resistance transmitting and diffusion, the infection of drug resistance salmonella has become the difficult point for preventing and treating the disease at present.And drug resistance The wide-scale distribution of salmonella has become potential public health harm problem.Therefore carry out the prevention and treatment of white scour of chicken salmonellosis Drug research has great importance.Wherein, Chinese medicine, especially Chinese medicine compound prescription are because its adverse reaction is small, be not easy to remain, do not pollute Environment is not likely to produce unique advantage possessed by drug resistance, is expected to obtain increasingly important role in terms of preventing and treating the disease.
3.2 this test press 0.25ml × 6.75 × 10 to 3 ages in days test chick9A/L(1 × MLD) take orally C79-13It is husky Men Shi bacillus liquid suspension replicates artificial DISEASE IN FLOCKS pathological model and obtains success.Infection morbidity chick is after oral vaccination Phase secondary disease after 4h~8h.It is fallen ill, and chick Major Clinical symptoms include spirit are depressed, are short of breath, have difficulty in breathing, piping, arranging white Serosity excrement, anus are blocked by serosity excrement, are dehydrated, is thin, and are occurred in succession after 8h~12h in turn dead.After death Dissect is visible: serious dehydration, enteron aisle hyperemia, bleeding, and gassy in enteron aisle, mucous membrane changes in acute inflammation, and liver extravasated blood goes out Blood, the canescence spotty necrosis point on the visible liver surface of individual chick, empsyxis, yolk bag absorb not congruent disease.Pathological section It observes the major lesions such as the visible heart, lung, liver, spleen, caecum organ and the disease substantially such as different degrees of bleeding, denaturation, necrosis occurs Reason process.It acquires morbidity chicken anus swab (excrement) separation of bacterial and dies of illness chicken gizzard, the heart, abdominal cavity separation of bacterial through bacteriology checking Prove that morbidity chick and dead chick are mainly caused by attacking toadstool in relation to (see Table 4 for details;Fig. 1~6).This result explanation uses this examination Artificial challenge's pathological model of proved recipe method duplication can guarantee being normally carried out for this test completely.
3.3 test results of the present invention show: intestines bacterium dissipates clearly middle and high dose application in the white scour of chicken case of artificial challenge, Premix addition, is used in conjunction 5d, can effectively reduce Chickens Infected disease incidence, and infection chick morbidity case fatality rate is effectively reduced.With infection Control group and low dose group, which are compared, has significant difference.And the protective effect, with positive control medicine Ciprofloxacin pre-mixing agent Protecting effect is quite (see Table 2 for details).In addition test result is also shown: even if the dead chick after medication, also shows using height After middle dosage intestines bacterium dissipates clearly, the morbidity death time can be slowed down, the pathology for mitigating metainfective intestines, liver, lung, spleen and caecum etc. becomes Change (being detailed in Fig. 1~6).This result shows that: intestines bacterium clearly dissipate with prevention and treatment salmonella infection chick cause DISEASE IN FLOCKS compared with Remarkable result.Test result affirmative intestines bacterium dissipates clearly the clinical effect for preventing and treating the white scour of chicken.
