Abstract
Twenty-seven kinds of organic dye-inactivated Sendai virus vaccines were prepared by treatment in dark at 23 C for 2 months or more, and selected with the high HA titers as a guide. Their nasal immunogenicities were examined in mice by contact infection and immunofluorescent method, and the relative merits of the dye-inactivants were determined. The strongest protection was elicited with acriflavine-, auramine O-, eosin Y-, neutral red-, night blue-, patent blue V-, thymol blue-, uranin-, and xylene cyanol FF-treated vaccines. Middling protective efficacy was induced by use of erio green B-, malachite green-, methyl green-, proflavine-, pyronin B-, and thionin-inactivated vaccines. Dye-inactivated vaccines that resulted in the weakest protection were Bindschedler's green-, bromothymol blue-, erythrosin B-, ethyl violet-, gallein-, light green SF yellowish-, methyl violet-, new methylene blue N-, phenol red-, rhodamine 6G-, spirit blue- and victoria blue B-treated ones. Serum HI titers developed by nasal vaccination were variable, and rose still more in most vaccinated groups postexposure. Elicitation of the most effective nasal immunogenicity in dye-inactivated vaccines appeared to depend on selective modification of capsid protein or ribose in viral core with dyes possessing definite functions, despite the different molecular structures.

Abstract
The survival of UV-irradiated cholera phage e5 was found to increase when the host cells, Vibrio cholerae MAK757, were exposed to a low dose of UV irradiation before phage infection (Weigle reactivation), indicating the existence of a UV-inducible DNA repair pathway (SOS repair) in V. cholerae MAK757. The induction signal generated by UV irradiation was transient in nature and lasted about 20-30 min at 37 degrees C. Maximal Weigle reactivation of the phage was obtained when the host cells were irradiated with a UV dose of 16 J/m2. V. cholerae MAK757 was also found to possess efficient photoreactivation and host cell reactivation of UV-damaged DNA in phage e5.

Abstract
Choleraphage phi 138 contains a linear, double-stranded, circularly permuted DNA molecule of 30 X 10(6) daltons or 45 kilobase pairs. Upon infection, the host DNA is degraded, and synthesis of phage-specific DNA is detectable 20 min after infection. The phage utilizes primarily the host DNA degradation products for its own DNA synthesis. A physical map of phi 138 DNA was constructed with the restriction endonucleases Bg/II, HindIII, and PstI. A concatemeric replicative DNA intermediate equivalent to eight mature genome lengths was identified. The concatemer was shown to be the precursor for the synthesis of mature bacteriophage DNA which is subsequently packaged by a headful mechanism.

Abstract
A radiation-sensitive mutant of the hypertoxinogenic strain 569B of Vibrio cholerae was isolated and characterized. The mutant, designated V. cholerae 569Bs, lacks both excision- and medium-dependent dark-repair mechanisms of UV-induced DNA damage while retaining the wild-type photoreactivating capability. Analysis of the UV-irradiated cell DNA by velocity sedimentation in alkaline sucrose gradient suggests that UV-induced pyrimidine dimers may not be incised in these cells. In contrast to the wild-type cells, the mutant cell DNA was degraded after treatment with nalidixic acid. The mutant cells failed to produce any detectable amount of cholera toxin as measured by ileal-loop assay.

Abstract
Repair of ultraviolet-light-induced DNA damage in a highly pathogenic Gram-negative bacterium, Vibrio cholerae, has been examined. All three strains of V. cholerae belonging to two serotypes, Inaba and Ogawa, are very sensitive to ultraviolet irradiation, having inactivation cross-sections ranging from 0.18 to 0.24 m2/J. Although these cells are proficient in repairing the DNA damage by a photoreactivation mechanism, they do not possess efficient dark repair systems. The mild toxinogenic strain 154 of classical Vibrios presumably lacks any excision repair mechanism and studies of irradiated cell DNA indicate that the ultraviolet-induced pyrimidine dimers may not be excised. Ultraviolet-irradiated cells after saturation of dark repair can be further photoreactivated.

Abstract
An increased sensitivity to inactivation was observed when ultraviolet light-irradiated Acholeplasma laidlawii cells were plated on medium containing either acriflavine or chloramphenicol. Chloramphenicol reduced liquid holding recovery (dark repair) to about 10% of that in untreated irradiated cells. In acriflavine treated cells no dark repair could be observed and there was a progressive degradation of cell DNA during holding. While the primary effect of acriflavine may be to inhibit excision repair, since ultraviolet-irradiated Mycoplasma gallisepticum (cells which lack an excision repair mechanism) show a slight increase in inactivation when plated on medium containing acriflavine the dye must also have some other effects on ultraviolet repair processes. Acriflavine treatment of A. laidlawii cells before ultraviolet irradiation has a protective effect, as seen by an increased cell survival.

Abstract
Caffeine increases the number of sister-chromatid exchanges (SCE) induced by mitomycin C (MMC) in human peripheral lymphocytes in culture. This enhancement decreases when the treated cells are held in medium before phytohemagglutinin (PHA) stimulation, or when caffeine is added to cultures some time after PHA stimulation but prior to DNA synthesis. There thus appears to be a caffeine-sensitive prereplication repair system, presumably an excision mechanism, capable of repairing a fraction of the MMC-induced DNA lesions.

Abstract
The mycoplasma Acholeplasma laidlawii was shown to have mechanisms for both host cell and ultraviolet (UV) reactivation of UV-irradiated mycoplasmaviruses. Host cell reactivation was examined by comparing the survival abilities of UV-irradiated double-stranded deoxyribonucleic acid mycoplasmavirus plated on both untreated and on acriflavine-treated cells. Acriflavine treatment inhibited cell exision repair. Decreased survival on the acriflavine-treated cells demonstrated host cell reactivation. UV reactivation was studied by comparing the survival of UV-irradiated virus plated on untreated cells with its survival on cells that received a small UV dose before plating. The UV-irradiated cells gave increased virus survival, showing UV reactivation. Similar experiments with a single-stranded deoxyribonucleic acid mycoplasmavirus showed that this virus could be UV reactivated, but not host cell reactivated.

Abstract
Experiments on the effect of ultraviolet (UV) light on the survival of vegetative Dictyostelium discoideum cells indicate that this is a relatively UV-resistant organism. Several factors suggest the presence of some type of repair process. Experiments to test for liquid-holding recovery and simple photoreactivation yielded negative results. Acriflavine and caffeine were utilized to possibly interfere with dark repair. Acriflavine produced no UV sensitization, but caffeine did cause a concentration-dependent decrease in survival of irradiated cells. When UV-irradiated cells were illuminated with photoreactivating light while suspended in caffeine, the survival increased above that for cells treated with caffeine alone, suggesting an overlap between lesions repaired by photorepair and dark repair. Growth experiments showed that UV light induced a dose-dependent division delay, followed by a period of retarded growth characterized by the presence of a constant fraction of nonviable cells in the irradiated population. The delayed exposure of cells to caffeine after irradiation showed that the magnitude of the caffeine sensitization diminished throughout the division-delay period. An action spectrum indicated probable nucleoprotein involvement in the induction of division delay. UV light retarded ribonucleic acid and protein synthesis and temporarily blocked deoxyribonucleic acid synthesis. However, synthesis of all three accelerated prior to the end of the division-delay period and then closely paralleled the increase in cell number.

Abstract
The rate of recovery of UV-irradiated Hemophilus influenzae from acriflavine-sensitized loss of colony-forming ability was studied at various acriflavine concentrations, UV doses, and temperatures. This rate (as calculated from an equation based upon certain assumptions) was on the order of 0.07 per minute per cell at 37 degrees C. This did not vary greatly with UV dose or acriflavine concentration, but did with temperature, giving a DeltaHdouble dagger of about 16 kcal/mole. In another set of experiments, cells bearing two genetic markers (resistance to 2000 mug/ml streptomycin and to 2.5 mug/ml novobiocin) were irradiated and then incubated without acriflavine. DNA extracts made from samples taken after various periods of incubation time were assayed on antibiotic-sensitive cells using acriflavine to inhibit repair during and following transformation. It was found that both in vivo irradiated markers were reactivated in the donor to approximately the same extent (with a rate constant of 0.04 per minute). This result was in contrast to the results obtained when extracted DNA bearing the same markers was irradiated in vitro and used to transform cells. In this latter case the streptomycin marker was much more sensitive than the novobiocin marker. This difference is interpreted as being due to the mechanics of the transformation system.

Abstract
Certain chemical compounds increase mutation frequency of Escherichia coli B/r significantly when used in conjunction with nonlethal ultraviolet (UV) dosages. Studies were done to elucidate the mechanism of this enhancing mutational effect. Dark survival curves showed that 500 mug of caffeine per ml in the postirradiation medium markedly decreased survival to 60 ergs/mm(2) of UV in strain B/r. Caffeine did not markedly decrease survival to UV in strain B/r WP-2 hcr(-). At least 90% of the mutations induced to streptomycin resistance by UV and 85% of those induced by UV with caffeine could be photoreversed. Experiments with thymine analogues suggested that thymine dimerization at the streptomycin locus was the primary premutational photoproduct induced by sublethal UV dosages. Caffeine did not interfere with the photoreversal of induced mutants, indicating that it probably does not bind to the photoreactivating enzyme or to a UV-induced lesion in the DNA. Addition of DNA or irradiated DNA with 500 mug of caffeine per ml resulted in no loss of the caffeine activity. The excision of UV-induced thymine-containing dimers from E. coli B/r T(-) was investigated in the presence and absence of caffeine. Our results indicated that caffeine prevents excision of thymine dimers, presumably by binding to the excising enzyme. This binding results in an impairment of repair, which produces the increase in mutant numbers.
