Gestational diabetes augments group B Streptococcus perinatal infection through disruptions in maternal immunity and the vaginal microbiota

V. Mercado-Evans, M. E. Mejia, J. J. Zulk, S. Ottinger, Z. Hameed, C. Serchejian, M. G. Marunde, C. M. Robertson, M. B. Ballard, N. Korotkova, A. Flores, K. A. Pennington, K. A. Patras

This study shows that gestational diabetes increases GBS perinatal infection by altering maternal immunity and vaginal microbiota, using a murine model.

Vaginal microbial dynamics and pathogen colonization in a humanized microbiota mouse model

M. E. Mejia, V. Mercado-Evans, J. J. Zulk, S. Ottinger, K. Ruiz, M. B. Ballard, R. A. Britton, K. A. Patras

This study evaluates a humanized microbiota mouse model to understand how vaginal microbiota composition influences susceptibility to urogenital pathogens, finding that certain bacterial taxa correlate with reduced pathogen levels but show inconsistent in vitro and in vivo effects.

Phage resistance accompanies reduced fitness of uropathogenic E. coli in the urinary environment

J. J. Zulk, J. R. Clark, S. Ottinger, M. B. Ballard, M. E. Mejia, V. Mercado, E. R. Heckmann, B. C. Sanchez, B. W. Trautner, A. W. Maresso, K. A. Patras

This study shows that phage resistance in UPEC arises quickly in the urinary environment but comes with fitness costs that reduce bacterial growth and virulence.

Human milk oligosaccharides reduce murine group B Streptococcus vaginal colonization with minimal impact on the vaginal microbiota

M. E. Mejia, S. Ottinger, A. Vrbanac, P. Babu, J. Zulk, D. Moorshead, L. Bode, V. Nizet, K. Patras

This study shows that human milk oligosaccharides reduce GBS vaginal colonization in mice without significantly altering the vaginal microbiota.
