Molecular and General Genetics MGG, 1972
Eight R factors are described which fall into four compatibility groups, distinct from previously described F-like and I-like groups. E. coli K12 carrying one of these factors, TP114, supports multiplication of the I-specific phage If1. However, TP114 is fully compatible with the I-like factor T-Δ and with all the other R factors described in this ...

Experimental infections were induced in weanling pigs orally both with nalidixic acid (NA)-sensitive and -resistant strains of Salmonella choleraesuis var. kunzendorf , designated RC221 and RC221NA, respectively. Prior to the time of infection, cultures of normal bacterial flora were isolated

R Factors for Aminoglycoside Antibiotics
Journal of Infectious Diseases, 1969The definition of R factors by Japanese scientists 10 years ago opened a new chapter in the saga of antibiotic resistance among enteric bacteria [1]. This package of extrachromosomal genes, comprised of the resistance determinants, which mediate resistance to a variety of environmental hazards, and the resistance transfer factors (RTF), which mediate ...

On the number of (r,r+1)‐ factors in an (r,r+1)‐factorization of a simple graph
Journal of Graph Theory, 2009AbstractFor integers d≥0, s≥0, a (d, d+s)‐graph is a graph in which the degrees of all the vertices lie in the set {d, d+1, …, d+s}. For an integer r≥0, an (r, r+1)‐factor of a graph G is a spanning (r, r+1)‐subgraph of G. An (r, r+1)‐factorization of a graph G is the expression of G as the edge‐disjoint union of (r, r+1)‐factors.
