| characteristics of non-cholera vibrios isolated from cases of human diarrhoea. | eighty-two organisms tentatively identified as non-cholera vibrios were isolated from cases of diarrhoea occurring in east pakistan. in 19 well-studied cases they were the predominant organism recovered, and a rise in agglutinating-antibody titre was found in six of these cases.because of this additional evidence that non-cholera vibrios cause diarrhoeal disease, it was necessary to evaluate simple screening tests as a means of recognizing them. it was found that all organisms that produced a ge ... | 1965 | 5294177 |
| protective antigens from el tor vibrios. 1. the preparation and properties of a purified protective antigen from an el tor vibrio (ogawa subtype). | a biochemically and immunologically homogeneous antigenic fraction having the properties of a lipopolysaccharide has been isolated from the culture supernatant of an el tor vibrio (ogawa subtype). this antigen was very specifically protective for mice challenged with ogawa strains of either el tor vibrios or vibrio cholerae. rabbit antisera prepared against the antigen were passively protective for mice and highly vibriocidal but had little agglutinating activity. however, the antigen was able s ... | 1965 | 5294306 |

| detection of vibrio cholerae biotype el tor by purging. | previous studies have demonstrated the value of purging in detecting inapparent cholera infection, but the technique has not been generally accepted. the present study shows that the method can be recommended as a routine procedure to determine when convalescent cholera patients should be discharged from hospital. it may also be useful in detecting carriers of vibrio cholerae and for evaluating chemotherapy. in this study, five of the eight patients who excreted vibrios after purging had been tr ... | 1966 | 5296396 |
| interaction of vibrio cholerae and vibrio el tor. | soon after its entry into the indo-pakistan subcontinent in 1964, cholera el tor progressively replaced classical cholera. one of the probable reasons for this was found from laboratory studies of the interaction of the two choleragenic vibrios, v. cholerae and v. el tor. it was observed, in both in vitro and in vivo experiments, that in mixed culture el tor vibrios from cholera cases are capable of outgrowing and rapidly eliminating v. cholerae. the apathogenic el tor strains from the middle ea ... | 1966 | 5296397 |
| phage resistance in vibrio cholerae. | mukerjee cholera phages are being extensively used in the classification of vibrios. however, the studies reported here show that phage-resistant mutants that are exactly like the parent strains in all characteristics except phage reactions can easily be obtained. for this reason phage reactions should be considered only as a marker and not as the final arbiter in vibrio classification, e.g., in attempting to identify the el tor vibrio. confirmatory evidence should always be sought.it is also sh ... | 1966 | 5297802 |

| a controlled field trial of the effectiveness of cholera and cholera el tor vaccines in the philippines. | a controlled field trial on some 584 000 people in an endemic cholera el tor area in the philippines demonstrated that cholera vaccines gave moderate protection of short duration. injection of a single dose of vaccine prepared from either vibrio cholerae or el tor vibrios gave over 50% protection for the first 2 months. the immunity conferred by the v. cholerae vaccine declined rapidly after 3 to 4 months. the effectiveness of the el tor vaccine continued for 6 months. an oil-adjuvant vaccine pr ... | 1967 | 5300874 |
| preparation and laboratory tests of oil-adjuvant cholera vaccine. | in a search for cholera vaccines of improved efficacy, agar-grown strains of classical vibrio cholerae were killed with formol and emulsified with arlacel a in mineral oil; the final vibrio concentration was adjusted to 2 x 10(9) vibrios per adult dose (equal proportions of inaba and ogawa types).there was an unexplained discrepancy between determinations of the vibrio content, by cell counting and opacity measurements, and of the antigen content, by nitrogen measurements and the complement-fixa ... | 1967 | 5300875 |
| antibiotic therapy of cholera in children. | in a controlled trial of the effects of oral antibiotics in treating cholera in children in dacca, east pakistan, tetracycline was the most effective of 4 antibiotics tested in reducing stool volume, intravenous fluid requirement, and the duration of diarrhoea and positive stool culture. increasing the duration of tetracycline therapy from 2 to 4 days, or increasing the total dose administered, resulted in shorter duration of positive culture, but did not affect stool volume or duration of diarr ... | 1967 | 5301733 |

| serological studies in cholera. i. vibrio agglutinin response of cholera patients determined by a microtechnique. | an agglutinin test for the determination of antibody responses to vibrio cholerae, requiring only 0.025 ml of serum, has been developed. this microtechnique permits the determination of agglutinin titres using fingertip blood, with results comparable with those obtained using venous blood taken at the same time.among 364 serum pairs in bacteriologically confirmed cases of cholera from an endemic area of east pakistan, the second serum sample being obtained 6 days or more after the onset of sympt ... | 1968 | 5302302 |
| serological studies in cholera. 2. the vibriocidal antibody response of cholera patients determined by a microtechnique. | a microtechnique is described for the determination of vibriocidal antibodies to vibrio cholerae, using 0.025 ml of fingertip blood or venous serum per test. this test could be used in epidemiological surveys, or as a routine test on patients admitted to hospital.fourfold or greater rises in vibriocidal titre were noted for 96.5% of 370 bacteriologically confirmed cholera patients in an endemic area of east pakistan (91.5% for the 94 children under 5 years in the study group). it is necessary to ... | 1968 | 5302303 |
| serological studies in cholera. 3. serum toxin neutralization--rise in titre in response to infection with vibrio cholerae, and the level in the "normal" population of east pakistan. | a method has been evaluated for the titration of antibodies to vibrio cholerae, based on the ability of sera containing such antibodies to neutralize the inflammatory effect of a factor from v. cholerae cultures on the skin of test animals.ninefold or greater rises in toxin-neutralization titre were found in 73% of 111 bacteriologically confirmed cholera patients in an endemic area of east pakistan, and in 2.5% of bacteriologically negative patients. this method compares well with the microtechn ... | 1968 | 5302304 |
| cholera vaccine field trials in east pakistan. 2. effectiveness in the field. | a cholera-vaccine field trial in a rural area of east pakistan where cholera is highly endemic has indicated that a high-potency whole-cell vaccine can provide significant protection against disease due to vibrio cholerae for at least 18 months. this vaccine gave more than 70% protection during the first cholera season after vaccination. in the second cholera season after the administration of a single dose of vaccine, protection fell in those under 5 years of age, while continuing at significan ... | 1968 | 5302329 |
| the relationship of vibriocidal antibody titre to susceptibility to cholera in family contacts of cholera patients. | a bacteriological and serological study of family contacts of 81 cholera patients was carried out in dacca, east pakistan. in the 10-day follow-up, 78 (16.7%) of 466 contacts were found to be infected with vibrio cholerae; half of them were symptomatic and 29 had to be admitted to hospital. a study of serum pairs revealed a 4-fold, or greater, rise in titre in 86% of those infected in whom diarrhoea was present, and in 77% of individuals with inapparent infections. the infection rate fell marked ... | 1968 | 5303331 |

| report of the 1966-67 cholera vaccine field trial in rural east pakistan. 2. results of the serological surveys in the study population--the relationship of case rate to antibody titre and an estimate of the inapparent infection rate with vibrio cholerae. | the 1966-67 cholera vaccine field trials in east pakistan tested 1- and 2-dose schedules of a commercial cholera vaccine in 40 000 children aged 3 months to 14 years. randomsample serological surveys, made prior to the inoculations and 3 months and 6 months after the inoculations, demonstrated that there was a rise in the vibriocidal titres of the vaccinated children during the first 3 months after inoculation and a subsequent fall by the end of the second 3 months. the antibody response to 2 do ... | 1969 | 5306539 |
| study on vibrio cholerae infection in a small community in calcutta. joint icmr-gwb-who cholera study group, calcutta, india. | the presence of a high level of latent infection in an affected community was postulated as one of the conclusions of earlier studies undertaken during cholera epidemics. a small community, consisting of 59 persons, was investigated for 100 days to determine the prevalence and persistence of infection after the occurrence of 2 index cases of cholera. in the community 39 excretors (66.1%) were detected, the 2 index cases and 37 carriers. excretion of vibrio cholerae was detected as much as 100 da ... | 1970 | 5312994 |
| study on the transmission of e1 tor cholera during an outbreak in can-itom community in the philippines. | during surveillance for cholera in the community of can-itom (negros occidental, philippines) in which the disease is endemic, a limited outbreak of cholera occurred. although it was not possible to determine how the infection arose, the index case was detected and the spread of infection traced. the infection was found to be transmitted initially from person to person until the water of a dug well became contaminated, as a result of which a water-borne outbreak of a rather explosive nature occu ... | 1970 | 5312996 |
| isolation of vibrio cholerae from nightsoil during epidemics of classical and e1 tor cholera in east pakistan. | a clear difference has been observed between the classical inaba v. cholerae and the el tor ogawa v. cholerae in relation to the ability to isolate the organism from the environment.an early attempt to utilize nightsoil sampling as a tool to measure the extent of infection in the community during an epidemic of classical inaba cholera in dacca, east pakistan, in the spring and fall of 1968 proved unsuccessful. during an epidemic caused by both the classical inaba and the el tor ogawa vibrios in ... | 1970 | 5312997 |

| vibriocine production in the cholera and el tor vibrios. | various tests have been developed to differentiate vibrio cholerae and v. el tor, since the latter was formerly considered to be of little clinical importance. more recently, however, it has become evident that these two organisms can produce an identical disease. consequently, it is of interest to detect similarities between them. in the present report, a method for the detection of bacteriocine ("vibriocine") activity of v. cholerae and v. el tor is described. the production of vibriocine appe ... | 1965 | 5322753 |

| fine structure of vibrio cholerae during toxin production. | the fine structural changes associated with cell growth and toxin production have been examined in vibrio cholerae strain 569b. no morphological alterations in the cell envelope are apparent during logarithmic growth with thin-section techniques. however, internal swelling, suggesting alteration of cell envelope permeability, is evident particularly during the late logarithmic and early stationary phases of growth. certain extracellular material demonstrable with negative-stain techniques does a ... | 1969 | 5361220 |
| somatic o antigen relationship of brucella and vibrio cholerae. | the antigenic relationship between brucella species and vibrio cholerae was examined by agglutinin and agglutinin-absorption tests by using rabbit antisera. brucella antisera agglutinated only the inaba serotype of v. cholerae and at low titer. inaba-reactive antibody was absorbed by either heat-stable (100 c, 2 hr) ogawa or inaba o antigens. cholera antisera from rabbits immunized with either o or ho antigens of either ogawa or inaba serotypes contained brucella agglutinins. this activity was a ... | 1969 | 5370272 |
| progressive changes of vibrio serotypes in germ-free mice infected with vibrio cholerae. | germ-free mice inoculated with vibrio cholerae became colonized with vibrios throughout the gastrointestinal tract, but they did not become ill. high vibrio concentrations in the feces were observed throughout the 3 months of observation in spite of the presence of serum antibody. reciprocal conversions of both inaba and ogawa serotypes occurred regularly after inoculation and could be correlated temporally with the appearance of serum-agglutinating antibody. both of these smooth serotype were l ... | 1969 | 5370274 |
