A child was suffering from fever (38 ºC), cough, pharyngitis and his chest x-ray showed pneumonia at lower part of left lung. He was treated with penicillin and did not respond to treatment. Gram-stain and Acid-fast staining of sputum did not show Streptococcus pneumoniae or Mycobacterium tuberculosis. Using a molecular method (PCR), no virus was detected. What is this type of pneumonia is called and what is the most possible bacterial causative agent and how you confirm it

Mycoplasma pneumonia

Explanation:

This is because with this type of pneumonia symptoms are milder than other which would tell why the fever is low and there are very few symptoms.

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.    

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
