Microbial growth inside saline-filled breast implants.

In vitro and in vivo experiments were conducted to

determine whether intraluminal saline in breast

implants can support the growth of common

wound-infecting microorganisms over a prolonged period

of time. The bacteria tested were Staphylococcus

aureus, Staphylococcus epidermidis, Escherichia coli,

Corynebacterium jeikeium, Enterobacter cloacae,

Klebsiella pneumoniae, and Pseudomonas aeruginosa.

Three fungal species also were tested: Aspergillus

fumigatus, Paecilomyces variotii, and Candida

albicans. In the in vitro study, four organisms

survived in flasks of sterile saline for the 2 weeks

in which serial cultures were performed: K.

pneumoniae, C. albicans, A. fumigatus, and P.

variotii. In the in vivo study, 61 white rabbits (122

implants) received both an experimental implant

inoculated with one of the test organisms and a

control implant containing only sterile saline. They

were sacrificed at 1-, 3-, or 6-month scheduled

endpoints. None of the control implants containing

sterile saline had positive cultures. In contrast, the

intraluminal saline was culture positive for 7 of the

10 inoculated organisms after varying lengths of time:

S. epidermidis, E. coli, E. cloacae, K. pneumoniae, P.

aeruginosa, A. fumigatus, and P. variotii. Samples of

capsular tissue also were cultured. Of the 122

capsular tissue specimens, 21 (17 percent) had

positive cultures and surrounded both inoculated and

sterile implants. In most instances, capsules that

were culture positive contained an organism different

from the one that had been inoculated in the group. In

only 3 cases was the same organism cultured from both

the periprosthetic tissue and the intraluminal saline,

and these may represent instances of the inoculated

organism migrating through the implants filler valves.

The data show that several types of bacteria

(particularly gram-negative species) and fungi can

grow and reproduce in a restricted saline environment

for extended periods of time.

No breast implant is safe. Even my silicone implants were filled with bacteria and growth. My one implant was SOLID BLACK! It was like I wasn't already freaked out enough and then when I saw my implants I freaked out all over again!Rogene S <saxony01@...> wrote: If there was ever a doubt that saline is safe, therewon't be after reading this! - Rogenehttp://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve & db=pubmed & dopt=Abstract & list_uids=9207676Microbial growth inside saline-filled breast implants.Young VL, Hertl MC, Murray PR, Jensen J, Witt H,Schorr MW.Division of Plastic and Reconstructive Surgery,Washington University School of Medicine, St.
