“…The emergence of resistant salmonella strains after feeding tetracycline in the ration of poultry was demonstrated by Huey and Edwards (1958), Garside et al (1960), Ramsey and Edwards (1961), McWhorter et al (1963) and Yurack (1964). Transfer of drug resistances to E. coli K12 F" recipient was observed to occur by Smith (1970).…”

Two separate experiments were conducted to assess the shed rate and duration of shed of S . typhimurium organisms from turkey poults orally infected with chlortetracycline-sensitive S. typhimurium in relation to chloretetracycline (CTC) given in the feed at 0, growth promotant, subtherapeutic and therapeutic levels; the emergence of resistant S. typhimurium organisms in reference to the diet given; in vitro transfer of drug resistance from thses resistant S. typhimurium donor cultures to multiply-sensitive E. coli recipients; and phage type changes, is any, of these S. typhimurium isolates. The results showed that increasing CTC in the diet from 0 to the three levels of antibiotic supplementation, appeared to (a) reduce shed and duration of shed corresponding to each level used; (b) cause a minimal development of drug resistance and its transfer (usually at sub-therapeutic levels of CTC supplementation) for the duration of the experiment; and (c) induce phage type changes in some of the S. typhimurium isolates. These phage type changes question the validity of using phage typing as a tool in epidemiological investigations.

“…Individual events in the complicated sequence have been documented, such as the selection for and persistence of resistant bacteria in food-producing animals resulting from the use of subtherapeutic doses of antimicrobials (7)(8)(9)(10)(11), the frequent presence of resistant Salmonella in products of animal origin (12,13), the transmission of resistant microorganisms to humans (6,14), and human disease resulting from multiply resistant bacteria (1). However, outlining all these steps in a sequence is rarely possible and does not indicate the relative frequency with which resistant bacteria arise from animal and human populations (15).…”

“…The poriferan origin of stromatoporoids and favositids is still a matter of considerable controversy. Stromatoporoids in a broad sense are apparently a systematic hotchpotch representing such distant groups as cyanobacteria (8), sponges (9), and coelenterates (10). For the favositids, however, poriferan (11) and zoantharian (12) models have been discussed, but for neither model is there satisfactorily conclusive evidence.…”

The importance and origin of antimicrobial-resistant Salmonella infections were examined in 52 outbreaks investigated by the Centers for Disease Control between 1971 and 1983. The case fatality rate was higher for patients infected with antimicrobial-resistant Salmonella (4.2 percent) than for those with antimicrobial-sensitive infections (0.2 percent). In the 38 outbreaks with identified sources, food animals were the source of 11 (69 percent) of 16 resistant and 6 (46 percent) of 13 sensitive outbreak strains.

“…The very scanty literature dealing with antibiotic resistance of sizable samples of pathogenic Enterobacteriaceae which were not derived from one or a few epidemic sources was reviewed by Ramsey and Edwards (1961) and will not be repeated here. Among investigations not previously cited was that of Garside, Gordon, and Tucker (1960), who found that 13.5 % of 362 salmonellae isolated from fowls in Great Britain in 1957-1959 were resistant to chlortetracycline. It is notable that these workers found the occurrence of resistant strains more frequent in S. thompson (39 %) than in S.…”
