Cardiovascular, Lymphatic and Respiratory System Microbes Organism Type of Organism Characteristics of organism Diseased Caused Sign and symptoms Hallmark of disease (if Remarks any) Streptococcus Bacteria Gram-positive cocci; facultative Dental caries, e ective Fever fatigue, heart murmurs, Bio lm formation on Enters bloodstream through dental mutant anaerobe; forms bio lms endocarditis shortness of breath, petechiae damaged valves; procedures or oral injuries bacterial colonization in the bloodstream Francisella tularensis Bacteria Gram-negative coccobacillus; Tularemia (Rabbit fever) Fever, chills, swollen lymph Ulceroglandular form Zoonotic disease; transmitted through aerobic; intracellular pathogen nodes, skin ulcers, fatigue, and with skin ulcer at entry tick bites respiratory distress site; severe pneumonia in inhalational tularemia Brucella Abortus Bacteria Gram-negative coccobacilli; non- Brucellosis Recurring fever, night sweats Undulant fever pattern, transmitted through unpasteurized motile; facultative intracellular joint and muscle pain, fatigue, granulomas in liver/ dairy products or contact with infected pathogen hepatosplenomegaly spleen livestock Yersinia pestis Bacteria Gram-negative bacillus;
