Cephalosporin compounds of Formulas II ##STR1## where R is hydrogen or a pharmaceutical cation, in which case R. sub. 1 is not present, or R is hydrogen or a chemical bond when R. sub. 1 is an acid addition salt anion, and R. sub. 2 is (a) hydrogen, (b) a duplicate of the formula I compound to form a dimer, (c) an aminocarbonylmethyl, or (d) an --SR. sub. 3 group where R. sub. 3 is alkyl, cyclohexyl, phenyl, chloro-substituted phenyl, nitro-substituted phenyl, benzyl or furfuryl, have been found to be valuable as antibiotics for treating warm-blooded animals to combat pathogenic bacterial infections which cause diseases such as the commonly known "shipping fever".
