Leptospira - Wikipedi

  1. Leptospira (Ancient Greek: leptos, 'fine, thin' and Latin: spira, 'coil') 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
  2. Leptospire definition is - any of a genus (Leptospira) of slender aerobic spiral-shaped spirochetes that are free-living or parasitic in mammals
  3. ated water can also cause infection. Outbreaks of leptospirosis are usually caused by exposure to conta

The leptospire bacteria have a predilection for the kidneys and the urinary tract where they may produce a persistent infection. The leptospire organisms may be excreted with the urine resulting in transmission of the bacteria. Infective urine constitutes the major sources of infection for humans, domestic animals, and wild animals LEPDT : Leptospirosis is a zoonotic disease of worldwide prevalence, though the majority of infections occur in warm, tropical climates. Wild mammals, typically rodents, are the primary, natural reservoir for pathogenic strains of Leptospira, however, domestic animals (eg, dogs) also represent a major source of human infection. Leptospira are Gram-negative spirochetes with at least 20.

One of the leptospire's unique characteristics is that it tends to cluster in certain body areas. Once infected, it can take up to three weeks for clinical signs to develop in a horse Leptospira: [ lep″to-spi´rah ] a genus of aerobic, finely coiled spirochete bacteria with hooked ends. L. inter´rogans is the causative agent of leptospirosis The organism settles in the kidneys and begins to reproduce, leading to further inflammation and then kidney failure. Depending on the type of leptospire involved, other organ failure (especially liver) can be expected as well. Make no mistake, leptospirosis is a life-threatening disease with worldwide significance and people can be infected, too

Role of Opsonization in Leptospire Survival and Interaction With MΦ. Early studies performed from 1960 to the mid-1980s showed that in vitro incubation with nonimmune serum does not exert bactericidal activity against pathogenic leptospires (11, 13, 28, 29).These studies described that pathogenic, but not saprophytic, leptospires were resistant to complement-induced destruction (11, 28, 29) Leptospirosis is an infectious disease of humans and animals that is caused by pathogenic spirochetes of the genus Leptospira.It is considered the most common zoonosis in the world and is associated with settings of poor sanitation and agricultural occupations involving contact with animals or water

Any of various gram-negative, spirochete bacteria of the genus Leptospira that are either free-living or parasitic, including the causative agent of.. Most leptospire-infected cells stayed at the G1 phase, whereas depletion or inhibition of p53 caused a decrease of the G1 -phase cells and the early apoptotic ratios. Infection with spirochaetes stimulated a persistent activation of p53 and an early activation of Akt through phosphorylation The traditional system divided the genus into 2 species: the pathogenic Leptospira interrogans and the nonpathogenic Leptospira biflexa. These species were divided further into serogroups.

Leptospire is a specific kind of bacteria called a spirochete. It's different from other bacteria in that it cannot be easily cultured in a laboratory, meaning that it makes it very difficult for your veterinarian to definitively diagnose that your dog is sick The leptospire is a particular type of bacteria called a spirochete. It's unique from other bacteria in that it cannot be easily cultured in a laboratory, which makes it a challenge for your veterinarian to definitively diagnose your sick dog. The leptospire multiplies in the kidneys of reservoir hosts, such as deer, skunks, and raccoons Disinfecting surfaces and non-porous materials is extremely simple, as the leptospira bacterium is very sensitive to disinfectants, soaps and many other household chemicals even at low concentrations. Despite the bacteria being extremely dangerous during an infection, they are one of the easiest to control - at least within buildings The leptospirosis vaccine is a non-core vaccine, which means it is an optional vaccine that dogs can benefit from based on risk for exposure to the disease. Veterinarians will recommend this vaccine based on a dog's lifestyle and reasonable exposure risk

Leptospiroză. Leptospiroza este o boală infecțioasă acută care se manifestă prin febră, intoxicație, cefalee, dureri musculare, mai ales la gambe, afectarea rinichilor, a ficatului, sistemului nervos și cardiovascular. A fost descrisă prima dată de Adolf Weil în 1886, motiv pentru care se numește și Boala lui Weil Discussion: Disease Description: Leptospirosis is a worldwide disease of animals and humans and causes serious economic loss to the livestock industry. 1 The disease is usually transmitted by direct or indirect contact with leptospire-infected urine

Leptospire prolaze (penetriraju), aktivno se gibajući, sluznice i/ili oštećenu kožu, dospijevaju u krv (leptospiremija) u kojoj se odmah počinju umnažati čemu osobito pogoduje pH krvi (7,2 do 7,4).Opseg oštećenja unutrašnjih organa je različit, a ovisi o virulenciji serovara i prijemljivosti domaćina. Neki su serovarovi više patogeni za pojedine domaćine () Vertical transmission is an important alternative route for Leptospira sp. spread in ewes under semiarid conditions. •. Central nervous system is an important extra-renal site of leptospire colonization. •. Molecular detection is an essential tool in the investigation of Leptospira sp. carrier ewe fetuses Once the leptospire enters the host, the pathogen reproduces. The survival rate of the leptospires depend on the immune system of the host, a suppressed immune system means the leptospires are more likely to survive and infect the host. Once they survive initial contact, they need to spread throughout the body Leptospire electron micrograph. Leptospira are spiral-shaped, highly motile aerobic spirochetes with 18 or more coils per cell. They can be distinguished morphologically from other spirochetes by their unique question mark hook at the end of the bacterium. Courtesy of Dr. Vanaporn Wuthiekanun
