Gram negative coccobacilli are short, rod-shaped bacteria that do not retain the crystal violet stain used in the Gram staining procedure, appearing pink under a microscope. Their clinical significance lies in their association with various infections, particularly respiratory and systemic diseases, often requiring specific antibiotic treatment due to their resistance patterns. An example is Haemophilus influenzae, which can cause pneumonia and meningitis, highlighting the importance of accurate identification for effective management.
