In Vitro Bactericidal Activity of Streptococcus pneumoniae and Bactericidal Susceptibility of Staphylococcus aureus Strains Isolated from Cocolonized versus Noncocolonized Children
Regev-Yochay, Gili; Malley, Richard; Rubinstein, E.; Raz, M.; Dagan, R.; Lipsitch, Marc (American Society for Microbiology, 2007)Streptococcus pneumoniae is bactericidal to Staphylococcus aureus in vitro. To determine whether this in vitro effect accounts for the inverse relation between S. pneumoniae and S. aureus colonization reported in previous ... -
Interference between Streptococcus pneumoniae and Staphylococcus aureus: In Vitro Hydrogen Peroxide-Mediated Killing by Streptococcus pneumoniae
Regev-Yochay, Gili; Trzcinski, K.; Thompson, Claudette M.; Malley, Richard; Lipsitch, Marc (American Society for Microbiology, 2006)The bactericidal activity of Streptococcus pneumoniae toward Staphylococcus aureus is mediated by hydrogen peroxide. Catalase eliminated this activity. Pneumococci grown anaerobically or genetically lacking pyruvate oxidase ... -
Is methicillin-resistant Staphylococcus aureus replacing methicillin-susceptible S. aureus?
Mostofsky, E.; Lipsitch, Marc; Regev-Yochay, Gili (Oxford University Press (OUP), 2011)Despite extensive research on the emergence of and treatments for methicillin-resistant Staphylococcus aureus (MRSA), prior studies have not rigorously evaluated the impact of methicillin resistance on the overall incidence ... -
SpxB Is a Suicide Gene of Streptococcus pneumoniae and Confers a Selective Advantage in an In Vivo Competitive Colonization Model
Regev-Yochay, Gili; Trzcinski, K.; Thompson, Claudette M.; Lipsitch, Marc; Malley, Richard (American Society for Microbiology, 2007)The human bacterial pathogen Streptococcus pneumoniae dies spontaneously upon reaching stationary phase. The extent of S. pneumoniae death at stationary phase is unusual in bacteria and has been conventionally attributed ... -
Streptococcus pneumoniae Carriage in the Gaza Strip
Shainberg, Bracha; Varon, Miriam; Roytman, Yulia; Ziv, Arnona; Goral, Aviva; Elhamdany, Abedallah; Rahav, Galia; Raz, Meir; Regev-Yochay, Gili; Abullaish, Izzeldin; Malley, Richard (Public Library of Science, 2012)Background: Pneumococcal infections cause major morbidity and mortality in developing countries. We report the epidemiology of S. pneumoniae carriage in a developing region, the Gaza strip, and evaluate the theoretical ...
