Why do Coxiella show variable Gram stain results-that is they may stain gram-positive or gram-negative?
Coxiella species exhibit variable Gram stain results due to their unique cell wall structure, which contains features of both Gram-positive and Gram-negative bacteria. They possess a thick peptidoglycan layer typical of Gram-positive bacteria, but also have an outer membrane similar to that of Gram-negative bacteria. This dual characteristic can lead to inconsistent staining, depending on the specific conditions and techniques used during the Gram staining process. Additionally, their intracellular lifestyle and atypical growth patterns further contribute to the variability in staining results.
What bacterial species are gram negative coccobacilli capable of living intracellular within a host?
