| Clostridium botulinum | | This microbe causes a childhood disease that is life-threatening to children under 5 yr. and is highly contagious. |
| Clostridium tetani | | As in China SARS caused great public fear, now MERS is doing the same thing in the Middle East, as both are caused by this type of virus that produces high fever as one of its symptoms/signs. |
| Poliomyelitis | | This bacterial spirochete causes a distinctive "bull's-eye" rash in the initial phase of the disease for about 80% of patients. |
| Rabies | | can be shed by asymptomatic carriers and is species usually involved in neonatal cases |
| West Nile Virus | | Responsible for several great pandemics in human history called plagues, this bacterium may be spread via flea bites. |
| Trypanosoma brucei | | This microbe causes a mycosis of the lower respiratory system that is known as "Valley Fever" as it occurs primarily in the San Joaquin Valley of California. |
| Brucella melitensis | | Known as a pneumococcus originally discovered by Louis Pasteur, a capsule is required for the infectious strains as shown by Dr. Frederick Griffith. |
| Francisella tularensis | | Oral lesions called Koplik's spots provide a definitive diagnosis |
| Yersinia pestis | | bacterium is spread by hard ticks and is released from salivary glands after several hours causing RMSF |
| Borrelia burgdorferi | | This protozoan causes Chagas' Disease and may result in congestive heart failure 10-20 years after the initial infection. |
| Yellow Fever | | Causes the leading type of pneumonia in children and young adults and is sometimes referred to as "walking pneumonia". |
| Dengue Fever | | Among the smallest of viruses, they are extremely infectious - a single virus has a 50% chance of causing a cold. |
| Ebola | | initial diagnostic sign is tightening of the jaw and neck muscles |
| Plasmodium species | | A bacterium whose toxin produces a pseudomembrane in the back of the throat that looks like leather and may be fatal. |
| Toxoplasma gondii | | Stress, aging or immune suppression may reactivate viruses in 15-20% of individuals who have had initial exposure |
| Trypanosoma cruzi | | Caused by 4 similar types of Flaviviruses, the common name of this disease is "breakbone" fever. |
| Streptococcus pyogenes | | This protozoan may cross the placenta during the first trimester of pregnancy causing all kinds of problems for the developing fetus including death. |
| Corynebacterium diphtheriae | | Caused by a protozoan carried by the Tsetse fly vector, the disease is known as African Sleeping Sickness |

| Mycobacterium tuberculosis | | originally discovered by Louis Pasteur there are 92 different strains of this pneumococcus |
| Bordetella pertussis | | The leading disease killer in the world, this microbe has MDR and XDR strains that have generated great concern around the world. |
| Coronavirus | | May produce a rash called scarlatina or scarlet fever that accompanies the sore throat and the tongue becomes strawberry red. |
| Respiratory Syncytial Virus (RSV) | | weak T cell responses lead to bacteria slowly multiplying in tissues and gradually destroying facial features |
| Coccidioides immitis | | tissue damage caused by "blebbing" or shedding of extrusions of outer membrane of this Gram-negative coccus |
