Leptospira
Leptospira interrogans
A genus of question mark-shaped bacteria spirochetes which is found in fresh water that is contaminated by animal urine. It causes LEPTOSPIROSIS.
Leptospirosis
Infections with bacteria of the genus LEPTOSPIRA.
Leptospira interrogans serovar icterohaemorrhagiae
A serovar of the bacterial species LEPTOSPIRA INTERROGANS, whose primary host is RATS.
Leptospira interrogans serovar canicola
A serovar of the bacterial species LEPTOSPIRA INTERROGANS, whose natural host is DOGS where disease is characterized by GASTROENTERITIS, and INTERSTITIAL NEPHRITIS.
Weil Disease
A severe form of LEPTOSPIROSIS, usually caused by LEPTOSPIRA INTERROGANS SEROVAR ICTEROHAEMORRHAGIAE and occasionally other serovars. It is transmitted to humans by the rat and is characterized by hemorrhagic and renal symptoms with accompanying JAUNDICE.
Agglutination Tests
Leptospira interrogans serovar australis
A serovar of the bacterial species LEPTOSPIRA INTERROGANS, characteristically associated with a severe zoonotic disease in humans.
Mesocricetus
Serotyping
Horse Diseases
Diseases of domestic and wild horses of the species Equus caballus.
Leptospira interrogans serovar autumnalis
A serovar of the bacterial species LEPTOSPIRA INTERROGANS, whose primary host is the MOUSE.
Comoros
A group of Indian Ocean Islands, the islands of Great Comoro, Anjouan, Mayotte, and Moheli, lying between northeast Mozambique and northwest Madagascar. The capital is Moroni. In 1914 they became a colony attached to Madagascar administratively and were made a French overseas territory in 1947. Except for Mayotte which remained French, Comoros became an independent republic in 1975. Comoros represents the Arabic qamar, moon, said by some scholars to be linked with the mystical Mountains of the Moon said to be somewhere in equatorial Africa. (From Webster's New Geographical Dictionary, 1988, p283 & Room, Brewer's Dictionary of Names, 1992, p122)
Floods
Disease Reservoirs
Animate or inanimate sources which normally harbor disease-causing organisms and thus serve as potential sources of disease outbreaks. Reservoirs are distinguished from vectors (DISEASE VECTORS) and carriers, which are agents of disease transmission rather than continuing sources of potential disease outbreaks.
Bacterial Outer Membrane Proteins
Rodent Diseases
Spirochaeta
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
Cattle Diseases
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.
Leptospira interrogans serovar hebdomadis
A serovar of the bacterial species LEPTOSPIRA INTERROGANS, whose frequent host is CATTLE.
Cricetinae
A subfamily in the family MURIDAE, comprising the hamsters. Four of the more common genera are Cricetus, CRICETULUS; MESOCRICETUS; and PHODOPUS.
Spirochaetales
Horses
Large, hoofed mammals of the family EQUIDAE. Horses are active day and night with most of the day spent seeking and consuming food. Feeding peaks occur in the early morning and late afternoon, and there are several daily periods of rest.
