Euseius tularensis is a species of mite in the family Phytoseiidae. [1]
Tularemia, also known as rabbit fever, is an infectious disease caused by the bacterium Francisella tularensis. Symptoms may include fever, skin ulcers, and enlarged lymph nodes. Occasionally, a form that results in pneumonia or a throat infection may occur.
Francisella is a genus of pathogenic, Gram-negative bacteria. They are small coccobacillary or rod-shaped, nonmotile organisms, which are also facultative intracellular parasites of macrophages. Strict aerobes, Francisella colonies bear a morphological resemblance to those of the genus Brucella.
The Thiotrichales are an order of Proteobacteria, including Thiomargarita namibiensis, the largest known bacterium.
Francisella tularensis is a pathogenic species of Gram-negative coccobacillus, an aerobic bacterium. It is nonspore-forming, nonmotile, and the causative agent of tularemia, the pneumonic form of which is often lethal without treatment. It is a fastidious, facultative intracellular bacterium, which requires cysteine for growth. Due to its low infectious dose, ease of spread by aerosol, and high virulence, F. tularensis is classified as a Tier 1 Select Agent by the U.S. government, along with other potential agents of bioterrorism such as Yersinia pestis, Bacillus anthracis, and Ebola virus. When found in nature, Francisella tularensis can survive for several weeks at low temperatures in animal carcasses, soil, and water. In the laboratory, F. tularensis appears as small rods, and is grown best at 35–37 °C.

Francisella novicida is a bacterium of the Francisellaceae family, which consist of Gram-negative pathogenic bacteria. These bacteria vary from small cocci to rod-shaped, and are most known for their intracellular parasitic capabilities. In this family, six species have been identified; however, the species F. novicida is under intense scrutiny. Though some believe it should be classified with its own species designation, others argue it should be reclassified as a subspecies under F. tularensis. If it were to be classified as a subspecies, F. novicida would join the other known subspecies including F. t. tularensis and F. t. holarctica. Biochemical assays for identifying F. tularensis subtypes and strains are not ideal because the results are often non-definitive and subject to variation, therefore these assays should only be considered as supplementary tests for identification of Francisella species and subspecies. Several strains of F. novicida or F. novicida-like bacteria have been described, and these strains may be resolved by PCR-based methods.
Boechera tularensis, common name Tulare rockcress, is a plant species endemic to California. It has been reported from Inyo, Mono, Tulare, Fresno, Madera, El Dorado and Mariposa Counties. It grows on rocky slopes in subalpine habitats at elevations of 2400–3200 m.
Several small RNAs have been identified in Francisella tularensis, pathogenic bacterium that causes the disease tularaemia. Very little is known about Francisella's regulatory networks that allow this bacterium to survive in many environments.
Polycesta tularensis is a species of metallic wood-boring beetle in the family Buprestidae. It is found in North America.
