Zoonotic Febrile Diseases

TSS is caused by a toxemic infection of the pathogen *Staphylococcus aureus*.

Toxic Shock Syndrome (TSS)

Streptococcal Toxic Shock-like Syndrome is caused by the pathogen *Streptococcus pyogenes*. 

Streptococcal Toxic Shock-like Syndrome

Puerperal Sepsis is most often caused by the pathogen *Streptococcus pyogenes*, but can also be caused by *Streptococcus spp., Staphylococcus spp., Enterococcus spp., Chlamydia spp., Escherichia coli, Klebsiella spp., Proteus spp., Peptostreptococcus spp., Bacteroides spp.,* and *Clostridium spp.*

Puerperal Sepsis

Infectious Arthritis can be caused by many bacteria, most notably caused by the pathogens *S. aureus* or *Neisseria gonorrhoeae*. 

Infectious Arthritis

This inflammation of bone tissue is most commonly caused by the pathogen *S. aureus*, but can also be caused by *M. tuberculosis, Pseudomonas aeruginosa, Streptococcus pyogenes, S. agalactiae*, Enterobacteriaceae species, and other microorganisms

Osteomyelitis

Rheumatic Fever is caused by infections of *S. pyogenes* that have nonsuppurative sequelae.

Rheumatic Fever

Bacterial Endocarditis can be caused by an infection of any of the following pathogens: *Staphylococcus aureus, viridans streptococci, Enterococcus faecalis, Haemophilus spp., Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens*, and *Kingella kingae*.

Bacterial Endocarditis 

Bacterial Pericarditis can be caused by *Staphylcoccus spp.* or *Streptococcus spp.*

Bacterial Pericarditis 

Gas gangrene is a serious disease that occurs when the endospores of *Clostridium perfringens* enter a wound and germinate. The resulting viable bacterial cells produce a toxin that causes the necrosis, or death, of surrounding tissue.

Gas Gangrene

Tularemia, also known as rabbit fever, is caused by the pathogen *Francisella tularensis*.

Tularemia

There are four pathogens that can cause Brucellosis in humans: *B. abortus, B. canis, B. suis*, and *B. melitensis*.

Brucellosis

Cat Scratch Disease is caused by the pathogen *Bartonella henselae.*

Cat Scratch Disease

Rat-bite fever can be caused by two pathogens: *Streptobacillus moniliformis* or *Spirillum minor*

Rat- Bite Fever

Plagues are a disease that affects humans and other mammals. It is caused by the bacterium, *Yersinia pestis*. Humans usually get the plague after being bitten by a rodent flea that is carrying the plague bacterium or by handling an animal infected with the plague.

A closed system of organs and vessels that circulate blood around the body to deliver oxygen, nutrients, and immune factors to tissues and to carry out waste products.

Circulatory System

A network of  vessels that manages fluid levels within the body, produces immune cells that combat infection, and filters out foreign bodies.

Lymphatic System

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.
