Anaplasmosis

Human Granulocytic Anaplasmosis (HGA) is caused by the bacterium Anaplasma phagocytophilum. It is contracted with the bite of infected ticks (Amblyomma americanum, Ixodes pacificus, Ixodes scapularis, Ixodes spinipalpis and Ixodes Dermacentor variabilis) and has been documented to transmit congenitally.

Babesiosis


Babesia is caused by several species of protozoan parasites. It is known to transfer through blood transfusion and ingestion, organ transplant and by congenital means. Transmission also occurs with the bite of infected ticks (Boophilus annulatus, Boophilus decoloratus, Boophilus microplus, Ixodes pacificus, Ixodes scapularis, Ixodes Dermacentor nitens and Rhipicephalus sanguineus).

Bartonella

Bartonella is caused by several species of bacteria. It is known to be transmitted by vectors such as fleas, biting flies, body louse, mosquitoes and ticks (Argasidae Carios kelleyi, Ixodes pacificus, Ixodes ricinus, Ixodes scapularis and Rhipicephalus sanguineus).

Bartonella has also been associated with the saliva of dogs and cats, normally passed on through scratches, bites or everyday grooming. Congenital transmission is also documented.

Brucellosis

Brucellosis is caused by several species of the bacterium Brucella. It is contracted through ingestion of contaminated milk products, direct blood contact with an infected animal and inhalation of the organism. Brucellosis is the most commonly reported laboratory-associated bacterial infection. Transmission has been documented by sexual contact, tissue transplant, congenital means and through breast-feeding. It is also contracted through flies and with the bite of an infected tick (Ixodes ricinus) .

Brucellosis is classified as a class B bioterrorism agent.

Colorado Tick Fever


Colorado Tick Fever is caused by the Colorado tick fever virus, a member of the Coltivirus genera. Some cases have been associated with exposures to the virus in laboratory settings and transfusion associated cases have been reported. Typically, it is contracted with the bite of infected ticks (Argasidae Otobius megnini, Ixodes Dermacentor andersoni, Ixodes Dermacentor occidentalis, Ixodes Dermacentor variabilis and Rhipicephalus sanguineus)

Colorado Tick Fever is classified as a Biosafety Level 2 arbovirus. Although prompt recovery is the expected outcome, rare fatalities are reported.

Ehrlichiosis


Human Monocytic Ehrlichiosis (HME) is caused by the bacterium Ehrlichiosis chaffeensis. It is contracted with the bite of an infected tick (Amblyomma americanum).

Human Granulocytic Ehrlichiosis (HGE) is caused by the bacterium Ehrlichia ewingii. It is typically contracted with the bite of infected ticks (Amblyomma americanum, Amblyomma maculatum, Ixodes scapularis, Ixodes Dermacentor variabilis and Rhipicephalus sanguineus), however, it has also been transmitted through contact with blood of fresh venison.

Lyme disease

Lyme disease is caused by the bacterium Borrelia burgdorferi. While it is still the most common vector-borne disease in the country, it is also transmitted in other ways. Infection occurs through blood transfusion, organ transplant, casual contact and by congenital means.

Typically, it is contracted with the bite of infected ticks (Amblyomma americanum, Amblyomma maculatum, Haemaphysalis leporispalustris, Ixodes affinis, Ixodes angustus, Ixodes cookei, Ixodes dentatus, Ixodes neotomae, Ixodes pacificus, Ixodes ricinus, Ixodes scapularis, Ixodes spinipalpis, Ixodes texanus, Ixodes Dermacentor albipictus, Ixodes Dermacentor andersoni, Ixodes Dermacentor occidentalis and Ixodes Dermacentor variabilis), however it has also been contracted through infected biting flies, mosquitoes, mites and fleas.

Mycoplasma

Mycoplasma infections are caused by several specific and unique species of cell-wall deficient bacteria. Mycoplasmas are transmitted through respiratory secretions, congenital means and the bite of infected ticks (Ixodes pacificus, Haemaphysalis leporispalustris and Argasidae Ornithodoros parkeri).

Query Fever


Q fever is caused by the rickettsia Coxiella burnetii. Because infected animals shed this organism in urine, feces, birth products, and milk; transmission occurs by inhalation of dust, ingestion of infected milk and the bite of infected ticks (Amblyomma americanum, Argasidae Otobius megnini, Ixodes Dermacentor andersoni, Ixodes Dermacentor variabilis and Rhipicephalus sanguineus). Infection can also be transmitted congenitally.

Coxiella burnetii could be developed for use in biological warfare and is considered a potential terrorist threat.

Relapsing Fever

Relapsing fever is caused by several species of the bacterium Borrelia. Most commonly, it is contracted with the bite of infected ticks (Amblyomma americanum, Argasidae Ornithodoros hermsi, Argasidae Ornithodoros parkeri, Argasidae Ornithodoros talaje and Argasidae Ornithodoros turicata). Infection can also be transmitted through the blood of rodents, the bite of infected lice or take place by contamination of a wound in the skin. It is also known to be transmitted congenitally.

Rocky Mountain Spotted Fever

Rocky Mountain spotted fever is caused by the bacterium Rickettsia rickettsii. Typically, it is contracted with the bite of infected ticks (Amblyomma americanum, Amblyomma cajennense, Amblyomma maculatum, Argasidae Ornithodoros parkeri, Argasidae Otobius megnini, Haemaphysalis leporispalustris, Ixodes pacificus, Ixodes Dermacentor andersoni, Ixodes Dermacentor occidentalis, Ixodes Dermacentor variabilis and Rhipicephalus sanguineus), but has also been acquired through blood transfusion and contamination of the skin with tick blood or feces.

The fatality rate is 20% or more in all patients.

STARI

Southern Tick Associated Rash Illness, formerly known as Master's disease, is caused by the bacterium Borrelia lonestari. It is contracted with the bite of infected ticks (Amblyomma americanum and Argasidae Carios capensis).
 



Tick Paralysis


Tick paralysis is a loss of muscle function that results from an unidentified protein toxin in tick saliva (Amblyomma americanum, Amblyomma maculatum, Amblyomma rotundatum, Argasidae Otobius megnini, Ixodes brunneus, Ixodes Dermacentor andersoni, Ixodes Dermacentor variabilis and Rhipicephalus sanguineus). Ticks attach to the skin to feed on blood. It is during this feeding process that the toxin enters the bloodstream. The paralysis is ascending; meaning it starts in the lower body and moves up and death by respiratory failure may result.

The fatality rate is 11.7%, despite the fact that there is usually a latent period of about 5 days before the ticks can produce enough toxin to cause paralysis, and paralysis can be avoided by removal of the ticks during that period.

Tularemia


Tularemia is caused by the organism Francisella tularensis. It is a highly infectious, invasive and potentially dangerous pathogen. So much so that the CDC has it listed as a possible bio-weapon.

Tularemia has many modes of transmission. Typically, contraction occurs with the bite of an infected vector such as the deerfly, the mosquito, the flea or the tick (Amblyomma americanum, Amblyomma maculatum, Argasidae Otobius megnini, Ixodes pacificus, Ixodes Dermacentor andersoni, Ixodes Dermacentor occidentalis and Ixodes Dermacentor variabilis). In addition, it is transmitted through contaminated water, food and soil.

Handling infected animals and ingesting infected game puts many at risk. Organisms can be transmitted directly through a bite from pets and wild animals, such as raccoons, snakes, and coyotes, which have bitten a sick or dead rabbit and thus have the bacteria in their mouths. Tularemia has also been acquired through inhalation of airborne particulates.

The fatality rate is 5-7% in untreated patients.
