Plasmids determining resistance to arsenic, mercury, silver, and tellurium compounds in Escherichia coli and Pseudomonas aeruginosa were tested for resistance to 40 other metal compounds. Resistance to trivalent boron and hexavalent chromium compounds was a property of certain P. aeruginosa plasmids.

Daily prophylactic application of either 1.0% silver sulfadiazine cream or 0.1% gentamicin cream was compared for effectiveness in preventing bacterial colonization of burn wounds and sepsis. Pseudomonas aeruginosa colonized the wounds of 37% of the 38 patients treated with silver sulfadiazine and 30% of the 33 patients treated with gentamicin; gentamicin-resistant P. aeruginosa colonized the wounds of 21% of the patients treated with gentamicin. Staphylococcus aureus colonization occurred in 55% of the patients treated with silver sulfadiazine, whereas colonization with Candida species occurred in 58% of the patients treated with gentamicin. Although gentamicin-resistant organisms caused no deaths their repeated appearance resulted in discontinuation of prophylaxiz with gentamicin cream. The next year P. aeruginosa strains resistant to gentamicin were isolated from burn wounds of only two patients who had not previously received parenteral therapy with gentamicin or tobramycin. Gentamicin cream should be reserved for treating patients with wounds infected by gentamicin-sensitive P. aeruginosa and those allergic to sulfa drugs. For most patients with burn wounds silver sulfadiazine is safe and effective as an antibacterial agent for topical prophylaxis.

In 1977-8 gentamicin-resistant strains of Pseudomonas aeruginosa became very common in a burns unit, over 90% being resistant at the peak of the outbreak. Some strains were also resistant to silver nitrate, though silver resistance was not found in any other strains of Ps aeruginosa isolated. Unlike the gentamicin resistance, the silver resistance was unstable, and strains became sensitive on repeated subculture. All the gentamicin-resistant strains of Ps aeruginosa were of the same serotype (O:11, H:2,5). Though gentamicin resistance could be transferred in vitro from resistant strains of Ps aeruginosa to one sensitive strain of Ps aeruginosa, there was no evidence of in-vivo transfer of gentamicin resistance between strains of pseudomonas in the patients' burns, nor was there evidence of transfer of gentamicin resistance between Ps aeruginosa and enterobacteria. Carbenicillin-resistant and gentamicin-resistant Ps aeruginosa were sometimes found in the same burns, but no gentamicin-carbenicillin (doubly) resistant strains were found among the 986 strains tested during the outbreak. The outbreak of gentamicin-resistant Ps aeruginosa from burns was not reduced by stopping treatment with gentamicin and its analogues but only by segregating all patients with Ps aeruginosa in one of the two wards of the unit and admitting new patients only to the other ward.

66 burned patients admitted to the Burn Unit from Jan. to Sept., 1977, were studied. Topical therapy employed was mafenide or silver sulfadiazine. The most common pathogens isolated in 288 burn wound cultures were Pseudomonas aeruginosa (42%), Klebsiella-Enterobacter (16%), and Staph, aureus (13%). Pseudomonas was sensitive to gentamicin in only 36.2% of instances. In 1976, 42% of Pseudomonas isolates was sensitive. During the period 1969-1973, 85.7% of the Pseudomonas was sensitive to gentamicin.

The wounds of 60 burned patients were treated topically with cerium nitrate, which was applied either as a cream or in aqueous solution. Cerium nitrate has a potent antiseptic effect in human burn wounds, especially against gram negative bacteria and fungi. Pseudomonas aeruginosa was recovered from the wounds infrequently and never predominated. Fungi were practically never found. No patient treated with cerium developed a necrotizing wound infection. Analysis of the detailed bacteriological data indicated that, in contrast to previous results with use of the nitrate or sulfadiazine salts of silver, when gram negative species predominated, the flora tended to be predominantly gram positive when cerium was used. Therefore, some patients were treated simultaneously with cerium nitrate and silver sulfadiazine; this resulted in an even more efficient suppression of the wound flora than was observed previously with either cerium alone or silver salts alone; results with the simultaneous topical therapy in patients with injuries that previously were uniformly lethal were excellent. No toxicity attributable to the use of cerium was observed, although one instance of methemoglobinemia due to nitrate was documented. The adsorption of topically applied cerium essentially is nil. The use of cerium nitrate was associated with a nearly 50 percent reduction in the anticipated death rate. Cerium nitrate is a promising new topical antiseptic agent for the treatment of burns, particularly when it is used in combination with silver sulfadiazine.

Transferable plasmids in gram-negative bacteria that confer resistance to potassium tellurite or tellurate were found. This re-istance was distinct from resistance to mercury, silver, or arsenic compounds and was unrelated to antibiotic resistance. In Escherichia coli, plasmids determine a 100-fold increase in the minimal inhibitory concentration for tellurite and a 10-fold increase in tellurate resistance. Many, but not all, of the plasmids belong to incompatibility group S. In Pseudomonas aeruginosa, tellurium resistance is specifically associated with incompatibility group P-2 and involves a 5- to 10-fold increase in tellurite or tellurate resistance.

Three groups of extensive burn patients of the surgical intensive care unit (ICU) have been compared: Group I: twenty patients, who were treated locally without silver sulfadiazinate (1968-1970); Group II: the twenty first patients topically treated with silver sulfadiazinate (1970-1972); Group III: twenty similarly treated patients, with silver sulfadiazinate, six years later (1976-1977). The groups are statistically comparable. All bacteriological samples were computerized; the chi-square method was used for statistical analysis of the data. The main conclusions are: (A) Silver sulfadiazinate treatment reduced Pseudomonas aeruginosa and Proteus sepsis. No change in Coliform bacilli sepsis was observed. After six years, a rise in Klebsiella sepsis and Candida sepsis was noted. (B) A quantitative estimate of infections in each group was made by measuring the percentage of positive samples, taking into account the five above-mentioned strains. In the beginning, silver sulfadiazinate reduced quantitative sepsis, but this benefit decreased after six years; the same evolution was demonstrated for positive blood bacteriology; severe septicaemia showed a parallel pattern.

A series of 645 consecutive burn injuries are analysed. There were 175 patients in the control group, 156 in the Maphenide (Sulfamylon) group and 314 in the Silver Sulphadiazine (S. S. D.) group. The Maphenide group and S.S.D. group are compared statistically with the control group. S.S.D. proved superior in relation to clinical infection rate and culture rate in reduction of Pseudomonas and Staphylococcus. Other culture rates were analysed. There were significant reductions in both groups for E. coli and Candida albicans. Pneumonias were significantly increased in both groups and the mortality rate reduced with S.S.D. Overall S.S.D. gave better results than Maphenide.

In this study the disc sensitivities of five organisms growing in pure cultures (Staphylococcus aureus, beta-hemolytic Streptococcus, Proteus mirabilis, Pseudomonas aeruginosa, and Candida albicans) were first determined against each of seven antibacterial agents (penicillin, streptomycin, gentamicin, kanamycin, silver nitrate, Sulfamylon, and Betadine). Then the sensitivity of each organism growing in combination with one of the others (10 combinations) was tested against each of the same antibacterials. Significantly increased and decreased sensitivities were found in 30 percent of the cultures with decreases largely predominating. Total obliteration of all sensitivity occurred 10 percent of the time. The changes in sensitivity were not distributed randomly but rather were associated more with particular agents and organisms. Sulfamylon, was associated with decreases 70 percent of the time with sensitivity obliteration in 50 percent of the tests. Streptococcus led all the organisms, being associated with decreases in half of the tests. It is possible that mixed-culture sensitivities could provide the most valid information when mixed infections exist, since they more closely simulate the real clinical situation. Therefore it is suggested that both mixed and pure culture sensitivity testing be done for all mixed infections.

Silver sulfadiazine when administered orally and subcutaneously to CF-1 mice in doses not exceeding 1,050 mg/kg proved to have minimal toxicity. No pathology or abnormal reactions were seen in CF-1 mice after receiving 1,050 mg/kg orally and subcutaneously once a day for 30 days. Silver sulfadiazine in doses of 1,050 mg/kg, once a day for 5 days cured mice of Plasmodium berghei even after splenectomy. Parasitemia was reduced to zero in 1-3 days and antimalarial activity was not inhibited significantly with doses of 313 mg/kg/day of PABA, thereby indicating that silver sulfadiazine's antimalarial mode of action is different from that of the sulfonamides. Doses of 1,050 mg/kg/day had significant activity against systemic infections of Pseudomonas aeruginosa.
