  • A study combining data estimated the global prevalence of intermediate Leptospira species in humans at 86%. The breakdowns occurred in regional areas displayed 96% incidence in the United States but only 17% in Asia. In India, occasional human cases tied to the L. inadai infection have surfaced over time, along with evidence of the bacterium circulating in animal reservoir hosts. L. inadai outbreaks are documented in many regions of India in last 30 years. L. inadai survives even cold temperatures but are normally habitat in warm and dry areas.
  • This species contributes to leptospirosis’s burden, especially where environmental factors enable its spread. The occurrence levels are at peak in southern province with 25.6%, 8.3%, at northern and the eastern region with only 3.1%. The prevalence ratios and surveillance are lacking for L. inadai infections. Conversely, this species influences to leptospirosis’s spread, uniquely where environmental factors enable its spread.
  • Leptospira inadai is a spiral shaped bacteria that are known for there corkscrew morphology. These are smallest pathogens with documented sizes of 0.1 to 0.15 µm which have helical amplitude.
  • These microbes are actively motile with compliant cell structure, they propose in a spiral motion with a wavelength of 0.5 µm.
  • The lethal antigens of Leptospira inadai contain the surface lipoprotein or Loa 22. And the genes reliable for its virulence include clpB, heme oxygenase and other flagellar elements. There are above 300 serovars of Leptospira species exhibiting various antigens and studied in pathology. These are also utilized for classification criteria.
  • Leptospira inadai species are reported with lacking type III secretion system for virulence and the L. inadai type strain was cultured using human skin from a patient. It is named with cultures collections like ATCC 43289 and DSM 22304. Commonly this strain is referred as strain 10 and also in databases, it is named as LYME.
  • Leptospira inadai is transmitted from contact with infected animal tissues, feces or urine. The bacterium progresses infection by penetrating into mucous membranes, cuts or via waterlogged skin. Later, this pathogen spread throughout the organs like liver, lungs and kidneys, it mainly aims to infect vital organs of the body.
  • The bacterium directly occurs via contaminated soil with feces and through contaminated water or soil. Transmission from maternal-fetal and sexual intercourse are also reported from developing countries. This pathogen is rarely occurred through breast feeding from mother to child. The infection caused by Leptospira inadai leads to severe diseases like acute hepatic damage, interstitial nephritis, and tubular necrosis of kidney, It causes pulmonary hemorrhage in respiratory system.
  • Adaptive Immune Response are majorly involved in defending Leptospira inadai in post infection responses. The B lymphocytes take a lead, and they distribute immunoglobulin G and immunoglobulin M against exclusive antigens of Leptospira inadai. The antibody response circulates throughout the blood and identifies these bacterial parts and binds it to nullify and exclude from the body.
  • Helper cells and cytotoxic cells are the core T lymphocytic cells that participate in organizing the immune reaction. They can distinguish exact antigens of L. interrogans and engage an immune response to supervise the infection.
  • Leptospira inadai diseases are called as leptospirosis. This bacterium causes severe illness in humans like organ failure.
  • The symptoms arise as the infection progresses like flu-like signs and mild fever. The patients may acquire headache, vomiting, and skin and eyes infections. Severe stomach pain can also be presented with knee and joints pain.
  • Microscopic Agglutination Test detects antibodies (IgM and IgG) when patient’s serum is analyzed under compound microscope. It is a basic method which is constructed on antigen-antibody reactions. The antibodies are emitted in reaction to Leptospira toxicity. The live L. inadai samples are mixed with blood to observe agglutination in the sample.
  • Enzyme-Linked Immunosorbent Assay exposes peculiar antibodies against Leptospira in the patient’s serum. It is a regularly employed for patient screening test in healthcare.
  • Polymerase chain reaction can identify the genetic substance (DNA) of Leptospira interrogans in urine, blood, or other clinical samples. PCR is substantially sensible and accurate, intended for early revealing of the L. interrogans strains through the acute period of the infection.
  • Urine Dipstick Test is rapid diagnostic test detects Leptospira antigens in the urine of infected individuals. It provides a quick screening method but lacks sensitivity and specificity compared to serological and PCR tests.
  • Resist interacting with possibly polluted water resources, such as stagnant water, floodwaters, or water contaminated with animal urine.
  • Control the inhabitants of rodents, which are the principal reservoirs of L. interrogans. It is perceived via appropriate waste management, rodent-proofing constructions, and rodent control procedures.
  • Clothing defensive outfits, like boots, gloves, and masks, while working in risky environments or supervising animals that could carry Leptospira.
