|{{TableHeadingColor}} |'''Abstract''' || <protect>Type 1 coliphage dried onto a glass surface was used as an indicator to monitor decontamination of biological safety cabinets. When desiccated virus was treated with formaldehyde vapor (5,000 or 10,000 ppm) adjusted to 70 to 90% relative humidity immediately before testing, viral inactivation was slow for the first 50 min but then accelerated, being complete in the next 10 min. However, when virus was incubated in an atmosphere containing 70% humidity for 1 h before formaldehyde was added, inactivation was complete within 3 min, indicating that careful attention must be paid to relative humidity in decontamination of safety cabinets.</protect>

 '''Graham, AC and Stocker, BA''' (1977) Genetics of sensitivity of Salmonella species to colicin M and bacteriophages T5, T1, and ES18.''J. Bacteriol.'' '''130''':1214-23

{|{{Prettytable}} align = 'center' width= '70%'
|-
|{{TableHeadingColor}} |'''Abstract''' || <protect>Nearly all of 62 strains of Salmonella paratyphi B were sensitive to colicin M and phage T5 but resistant to phages T1 and ES18 and to colicin B. All tested S. typhimurium strains were resistant to colicin M and phage T5, and many were sensitive to phage ES18. A rough S. typhimurium LT2 strain given the tonA region of Escherichia coli or S. paratyphi B became sensitive to colicin M and phage T5. We infer that the tonA allele of S. paratyphi B, like that of E. coli, determines an outer membrane protein that adsorbs T5 and colicin M but not phage ES18, whereas the S. typhimurium allele determines a protein able to adsorb only ES18. The partial T1 sensitivity of a rough LT2 strain with a tonA allele from E. coli or S. paratyphi B and also the tonB(+) phentotype of an E. coli B trp-tonB Delta mutant carrying an F' trp of LT2 origin showed that S. typhimurium LT2 has a tonB allele like that of E. coli with respect to determination of sensitivity to colicins and phage T1. Rough S. paratyphi B, although T5 sensitive, remained resistant to T1 even when given F' tonB(+) of E. coli origin. Classes of Salmonella mutants selected as resistant to colicin M included: T5-resistant mutants, probably tonA(-); mutants unchanged except for M resistance, perhaps tolerant; and Exb(+) mutants, producing a colicin inhibitor (presumably enterochelin). Some Exb(+) mutants were resistant to a bacteriocin inactive on E. coli but active on all tested S. paratyphi B and S. typhimurium strains (and on nearly all other tested Salmonella). A survey showed sensitivity to colicin M in several other species of Salmonella.</protect>

 '''Wagner, EF, Auer, B and Schweiger, M''' (1979) Development of Escherichia coli virus T1: escape from host restriction.''J. Virol.'' '''29''':1229-31

{|{{Prettytable}} align = 'center' width= '70%'

|{{TableHeadingColor}} |'''Abstract''' || <protect>The bacterial virus T1 grows interchangeably on different Escherichia coli strains (C, B, and K). This implies that T1 has an efficient mechanism to overcome the host restriction barrier. The DNA of T1 was found to be methylated independently of the hosts. The percentage of N6-methyladenine varied from 1.6 to 1.8, and the 5-methylcytosine content varied from 0.1 to 0.4%. In contrast, the range in percentage of N6-methyladenine and 5-methylcytosine found in the hosts was 0.7 to 2.4 and 0.0 to 1.1, respectively.</protect>
