Leptospira santarosai is a pathogenic species of Leptospira . [1]
Salmonella is a genus of rod-shaped (bacillus) Gram-negative bacteria of the family Enterobacteriaceae. The two species of Salmonella are Salmonella enterica and Salmonella bongori. S. enterica is the type species and is further divided into six subspecies that include over 2,600 serotypes. Salmonella was named after Daniel Elmer Salmon (1850–1914), an American veterinary surgeon.
Salmonella enterica is a rod-headed, flagellate, facultative anaerobic, Gram-negative bacterium and a species of the genus Salmonella. A number of its serovars are serious human pathogens.
Leptospirosis is a blood infection caused by the bacteria Leptospira. Signs and symptoms can range from none to mild to severe. Weil's disease, the acute, severe form of leptospirosis, causes the infected individual to become jaundiced, develop kidney failure, and bleed. Bleeding from the lungs associated with leptospirosis is known as severe pulmonary haemorrhage syndrome.
Lactobacillus acidophilus is a species of Gram-positive bacteria in the genus Lactobacillus. L. acidophilus is a homofermentative, microaerophilic species, fermenting sugars into lactic acid, and grows readily at rather low pH values and has an optimum growth temperature of around 37 °C (99 °F). L. acidophilus is found in the human and animal gastrointestinal tract and mouth. Some strains of L. acidophilus may be considered to have probiotic characteristics. These strains are commercially used in many dairy products, sometimes together with Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus in the production of acidophilus-type yogurt, or acidophiline. Its genome has been sequenced.
Leptospira is a genus of spirochaete bacteria, including a small number of pathogenic and saprophytic species. Leptospira was first observed in 1907 in kidney tissue slices of a leptospirosis victim who was described as having died of "yellow fever".
Chlamydia psittaci is a lethal intracellular bacterial species that may cause endemic avian chlamydiosis, epizootic outbreaks in mammals, and respiratory psittacosis in humans. Potential hosts include feral birds and domesticated poultry, as well as cattle, pigs, sheep, and horses. C. psittaci is transmitted by inhalation, contact, or ingestion among birds and to mammals. Psittacosis in birds and in humans often starts with flu-like symptoms and becomes a life-threatening pneumonia. Many strains remain quiescent in birds until activated by stress. Birds are excellent, highly mobile vectors for the distribution of chlamydia infection, because they feed on, and have access to, the detritus of infected animals of all sorts.
Leptospira noguchii is a gram-negative, pathogenic organism named for Japanese bacteriologist Dr. Hideyo Noguchi who named the genus Leptospira. L. noguchii is famous for causing the febrile illness in Fort Bragg, NC during World War II. There was 40 cases of this fever documented during each summer from 1942 to 1944; however, there were 0 deaths recorded from this outbreak. Unlike other strains of Leptospira that cause leptospirosis, L. noguchii is characterized by showing a pretibial rash on the victim. Its specific epithet recognises Hideyo Noguchi.
Leptospira interrogans is a Gram negative, obligate aerobe spirochete, with periplasmic flagella. When viewed through a dark-field microscope, it often resembles a question mark, and this gives the species its name. It is a member of the genus Leptospira. Some important pathogenic serovars from this species are Canicola, Icterohaemorrhagiae and Australis. L. interrogans is difficult to culture, requiring special media and extended incubation periods.
Ureaplasma parvum is a species of Ureaplasma, a genus of bacteria belonging to the family Mycoplasmataceae.

Salmonella enterica subsp. enterica is a subspecies of Salmonella enterica, the rod-shaped, flagellated, aerobic, Gram-negative bacterium. Many of the pathogenic serovars of the S. enterica species are in this subspecies, including that responsible for typhoid.
Leptospira weilii is a pathogenic species of Leptospira.
Leptospira borgpetersenii is a pathogenic species of Leptospira.
Leptospira meyeri is a saprophytic species of Leptospira.
Leptospira wolbachii is a saprophytic species of Leptospira.
Leptospira inadai is a pathogenic species of Leptospira.
Leptospira alexanderi is a species of Leptospira. Its type strain is strain L 60T.
Leptospira fainei is a pathogenic species of Leptospira, first isolated from pigs in Australia and named for University of Otago and Monash University microbiologist Dr. Solomon Faine.
Fructose-asparagine (F-Asn) is a glycosylamine compound that is most notably used by Salmonella during Salmonella-mediated inflammation of the intestine. In addition to Salmonella, several other species of bacteria may utilize fructose-asparagine as a nutrient. The name of the genetic locus that encodes the uptake capability in Salmonella is fra. This fra locus has five genes: fraR, fraB a fructose-asparagine deglycase, fraD a sugar kinase, fraA a fructose-asparagine transporter, and fraE a L-asparaginase. Notably, mutations in fraB cause the buildup of the toxic intermediate 6-phosphofuctose-aspartate (6-P-F-Asp). The buildup of 6-P-F-Asp has a bacteriostatic effect on fraB mutant cells, making FraB a potential drug target.
Leptospira alstonii is a gram negative, mobile, spirochete. It is flexible, helical, and motile by means of two periplasmic flagella. It is obligately aerobic and oxidase positive. It was named after J. M. Alston, a British microbiologist who made significant contributions to the study of Leptospirosis. It is one of nine human or animal pathogenic species of Leptospira. It was originally isolated from material submitted to the Veterinary Diagnostic Laboratory at Iowa State University during an outbreak of swine abortion in 1983. It has been isolated and stored in liquid nitrogen or Ellinghausen-McCullough-Johnson-Harris medium. It also has been isolated in China from a frog. The strain is also available from culture collections of the WHO collaborating centers. Lipase is not produced by this species. NaCl is not required for growth. Growth is inhibited by 8-azaguanine at 225 µg/mL or 2,6-diaminopurine (10 µg/mL) and copper sulfate. It contains serovars from the serogroup ranarum. DNA G+C content is 39±8 mol%.
