How to Identify Gram Negative Species

Using On Farm Culture to Improve Mastitis Treatment
Episode #10: How to Identify Gram Negative Species

Gram negative organisms cannot be differentiated at the genus level (such as E. coli, Klebsiella or Enterobacter) on the agar plates used in on-farm cultures. However, they can be identified as lactose negative or lactose positive by what color they ferment lactose in MacConkey agar. In this episode, Dr. Pamela explains what this means and discusses treatment options for a gram negative infection. Hint: gram negative infections often resolve on their own. Therefore, it is not always necessary to treat with antibiotics. Remember, it is always advisable to consult your local veterinarian when making these decisions.

Pseudomonas Aeruginosa Infection, And Treatment (Antibiotic)

Pseudomonas aeruginosa is a metabolically versatile ubiquitous gamma-proteobacterium that thrives in soil and aquatic habitats and colonizes the animate surfaces of plants, animals, and humans. P. aeruginosa may cause multiple infections in man that vary from local to systemic and from benign to life threatening. During the last few decades, the cosmopolitan Gram-negative bacterium has become one of the most frequent causative agents of nosocomial infections associated with substantial morbidity and mortality. Pneumonia and sepsis in intensive care unit (ICU) patients still have a bleak prognosis. Chronic airway infections with P. aeruginosa are a major cause of morbidity in people with cystic fibrosis (CF) or chronic obstructive pulmonary disease (COPD). Here we report on recent advances in the understanding of host–pathogen interactions with particular emphasis on infections with P. aeruginosa in humans. (See citation below)

Pseudomonas aeruginosa Infections

Pseudomonas aeruginosa is a Gram-negative, aerobic, rod shaped bacteria. It is a common microorganism that can cause disease in animals, including humans. It is also the cause of various plant diseases.

It can be found in soil, water, skin flora and many man-made environments. It has the ability to utilize a wide range of organic material for food. In humans and animals this versatility enables the microorganism to infect damaged tissues and infect those with weakened immune systems.
