The aim of this study was to determine the antimicrobial effect of ginger essential oil (Zingiber officinale) on Streptococcus strains that cause cervical lymphadenitis in guinea pigs (Cavia porcellus). Ginger essential oil was obtained through steam distillation, achieving a yield of 0.06%, where the majority component was α-Citral (21.11%). Abscesses were collected from animals with a positive diagnosis for cervical lymphadenitis in commercial farms. Twenty strains from clinical cases, 16 Streptococcus pyogenes strains, and 4 Streptococcus equi subsp zooepidemicus strains were identified and isolated. Four concentrations (65, 45, 25 and 5%) of the essential oil and three repetitions for each isolated strain were used. The largest average diameter of the inhibition halo was 15.12 m and 14.73 mm for strains of S. pyogenes and S. equi subsp zooepidemicus at a concentration of 65% with a limit sensitivity (SL) and medium sensitivity (SM) respectively according to the Duraffourd et al. scale. (1986), while concentrations of 25% and 45% had a limit sensitivity value (SL) of 9.53 mm and 12.19 mm for S. pyogenes; meanwhile mean values of 9.93 mm and 12.81 mm for S. equi spp zooepidemicus. The essential oil of ginger has in vitro antimicrobial activity against S. pyogenes and S.equi subsp zooepidemicus strains
