Streptococcus infection carries all the symptoms mentioned.
<h3><u>Explanation</u>:</h3>
<em>Streptococcus pneumoniae</em> and <em>Diplococcus pneumoniae</em> are the organisms that gram positive bacteria. These bacteria enters the respiratory system from droplet method propagation which is through aerosol or water droplet inhalation which are infected with these bacteria. These bacteria leads to the severe antigen antibody reaction inside lungs which leads to high rate of mucous secretion. This leads to formation of pneumonia.
These bacteria are mainly seen in tropical countries with warm climate and humid environment. These bacteria doesn't spread through contagious methods like touching. But the protection must be taken as these patients cough can contain lakhs of these bacteria which are enough to infect a healthy individual.
Legionella genus of bacteria are pathogenic gram-negative bacteria. The species Legionella pneumphila causes legionella infection which leads to legionellosis.
Legionellosis includes both the flu-like Pontiac disease as well as the acute highly severe pneumonia called the Legionnaires.
Legionellosis occurs when water droplets or aerosolized water contaminated with Legionella species is inhaled. These bacteria mostly are present in aquatic environment and can thrive and survive in water with warm temperatures.
Legionella infections are non-contagious and does not spread from person to person but only spreads through inhalation of contaminated water droplets.
Legionnaires causes lung inflammation and severe pneumonia and if untreated can also be fatal
