Bartonella Japonica
''Bartonella japonica'' is a species of bacteria in the genus ''Bartonella''. A strain of this species was originally isolated from the blood of a small Japanese field mouse (''Apodemus argenteus'').

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bartonella
''Bartonella'' is a genus of Gram-negative bacteria. It is the only genus in the family Bartonellaceae. Facultative intracellular parasites, ''Bartonella'' species can infect healthy people, but are considered especially important as opportunistic pathogens. ''Bartonella'' species are transmitted by vectors such as ticks, fleas, sand flies, and mosquitoes. At least eight ''Bartonella'' species or subspecies are known to infect humans. ''Bartonella henselae'' is the organism responsible for cat scratch disease. History ''Bartonella'' species have been infecting humans for thousands of years, as demonstrated by ''Bartonella quintana'' DNA in a 4000-year-old tooth. The genus is named for Alberto Leonardo Barton Thompson (1871–October 26, 1950), a Peruvian scientist. Infection cycle The currently accepted model explaining the infection cycle holds that the transmitting vectors are blood-sucking arthropods and the reservoir hosts are mammals. Immediately after infection, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small Japanese Field Mouse
The small Japanese field mouse (''Apodemus argenteus'') is a species of rodent Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are n ... in the family Muridae. It is endemic to Japan.

Large Japanese Field Mouse
The large Japanese field mouse (''Apodemus speciosus'') is a nocturnal species of rodent in the family Muridae. It is endemic to Japan. Distribution and habitat The species appears to be present on all Japanese islands. It inhabits forests, grasslands, and cultivated fields, including rice paddies, at any altitude. Though occupying the same broad ecological niche as ''A. argenteus'', the two species prefer different microhabitats: ''A. argenteus'' prefers dense canopy, while ''A. speciosus'' prefers open secondary forests. Foraging behavior Large Japanese field mice forage primarily at night, likely to avoid predation. They are omnivores but mostly known to be seed-eating mice, particularly around autumn and winter, as the mice hoard acorns and walnuts, which comprise 13-100% of their food. This makes them effective seed dispersers. Mast seeding can have serious effects on field mouse populations, including increases in overwinter survival, winter reproduction, and population de ...

Gram-negative Bacteria
Gram-negative bacteria are bacteria that do not retain the crystal violet stain used in the Gram staining method of bacterial differentiation. They are characterized by their cell envelopes, which are composed of a thin peptidoglycan cell wall sandwiched between an inner cytoplasmic cell membrane and a bacterial outer membrane. Gram-negative bacteria are found in virtually all environments on Earth that support life. The gram-negative bacteria include the model organism ''Escherichia coli'', as well as many pathogenic bacteria, such as ''Pseudomonas aeruginosa'', '' Chlamydia trachomatis'', and ''Yersinia pestis''. They are a significant medical challenge as their outer membrane protects them from many antibiotics (including penicillin), detergents that would normally damage the inner cell membrane, and lysozyme, an antimicrobial enzyme produced by animals that forms part of the innate immune system. Additionally, the outer leaflet of this membrane comprises a complex lipopol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
