Lysinibacillus fusiformis, originally discovered on the surface of beetroot by German biologist Dr. O. Gottheil in 1901, has a complex epidemiological history. In the 20th century, it was linked to the causation of tropical ulcers, particularly prevalent in Africa and Asia. However, divergent opinions emerged, suggesting that L. fusiformis infections might be contingent on a symbiotic relationship with specific spirochaete species.
In a significant reclassification in 2007, L. fusiformis was moved from the genus Bacillus to Lysinibacillus, a testament to its unique characteristics. Human infections, notably severe sepsis, & respiratory illnesses have been associated with L. fusiformis. A case of L. fusiformis septicemia was documented in a 65-year-old woman with diabetes mellitus in Taiwan in 2009.
Additionally, L. fusiformis has been recognized as a natural pathogen of Drosophila flies, and recent studies in 2022 and 2023 investigated the genetic basis of immune defense variation against L. fusiformis in different Drosophila melanogaster populations. Furthermore, L. fusiformis has been found beyond clinical contexts, isolated from cosmetic samples like exfoliating creams in the United States in 2018.

Species:L. fusiformis
Lysinibacillus fusiformis, a gram-positive bacterium, displays a rod-shaped morphology with non-motile characteristics. The active cells of this bacterium exhibit an approximate length ranging from 2.5 to 3.0 µm and a width ranging from 0.5 to 0.9 µm.
Under unfavorable conditions, L. fusiformis demonstrates the capability to form dormant endospores, known for their resilience against heat, chemicals, and ultraviolet light. These endospores are spherical and can be positioned either centrally or terminally within the enlarged sporangia.
The cell wall of Lysinibacillus fusiformis is composed of a peptidoglycan layer containing lysine, alanine, glutamic acid, and aspartic acid.
Lysinibacillus fusiformis exhibits a genomic repertoire that contributes to its virulence. The bacterium harbors genes responsible for producing toxins, enzymes, and transporters involved in its pathogenicity. Notably, the hemolysin III gene (hlyIII) governs hemolytic activity and cytotoxicity, while the sphingomyelinase gene (sph) plays a role in membrane disruption and tissue damage.
Additionally, the nonribosomal peptide synthetase gene (nrps) participates in siderophore biosynthesis, aiding in the acquisition of iron from the host. The genome of a representative strain, ZC1, spans approximately 4.65 megabases, encompassing 4,729 protein-coding genes, and maintains a moderate GC content of 37.3%. Noteworthy is the presence of the chrA gene, conferring resistance to chromate Cr (VI) and the ability to form endospores, ensuring survival under adverse conditions.
In 2010, a strain of L. fusiformis, B-1, was identified, adding to the understanding of its genetic makeup. The type strain, L. fusiformis AMNH 732, is associated with various culture collection numbers, including DSM 2898, ATCC 7055, JCM 12229, and NBRC 15717. Genomic analysis reveals the presence of the chrA gene, affirming chromate Cr (VI) resistance, a trait that enhances the bacterium’s adaptability in challenging environments.
fusiformis demonstrates the ability to form endospores, dormant and resilient structures that enable survival in harsh conditions. These endospores serve as a crucial mechanism for the bacterium to endure adverse environments and germinate when favorable conditions are reinstated.
The pathogenesis of L. fusiformis involves diverse transmission routes, primarily through contact with contaminated soil, water, plants, wounds, insect bites, or inhalation of aerosols. Once introduced into the host, L. fusiformis can colonize various anatomical sites, including the skin, mucous membranes, or respiratory tract, leading to the potential for local or systemic infections. Past reports have documented cases of skin ulcers and respiratory infections linked to L. fusiformis.
Researchers have proposed a symbiotic relationship between L. fusiformis and specific spirochetes, suggesting their collaboration in causing tropical ulcers. The bacterium’s pathogenicity is further augmented by the production of various enzymes, such as lipases, proteases, and phospholipases, which contribute to the degradation of host tissues, facilitating bacterial invasion.
Moreover, L. fusiformis can disseminate through the bloodstream, affecting multiple organs, including the heart, lungs, kidneys, and brain. This systemic spread poses a considerable risk, leading to severe and potentially life-threatening complications.
The skin serves as a robust physical and chemical barrier, preventing the entry of Lysinibacillus fusiformis. Chemical defenses within the skin, such as lysozyme, immunoglobulins, and antimicrobial peptides, act to eliminate or hinder bacterial growth.
In the event of breaches in the skin due to wounds or lesions, the body promptly activates the inflammatory response. This entails the recruitment of phagocytic cells, including neutrophils & macrophages, which engulf and eliminate invading L. fusiformis. Additionally, specific antibodies like IgG and IgA can neutralize toxins and impede the bacterium’s attachment to host cells.
Upon breaching the skin, if L. fusiformis enters the bloodstream, the immune system employs pathogen recognition mechanisms. Pathogen-associated molecular patterns (PAMPs), such as lipoteichoic acid and
peptidoglycan, are detected by PRRs (pattern recognition receptors) like toll-like receptors (TLRs) and NOD-like receptors (NLRs). Activation of these receptors’ triggers cytokine production, including interleukins and interferons, modulating the immune response and inducing fever. The complement system, a cascade of plasma proteins, enhances phagocytosis, opsonization, and lysis of L. fusiformis.
In the respiratory tract, mechanical defenses like nasal hairs, the mucociliary escalator, and the cough reflex prevent bacterial entry.
Chemical defenses, including lysozyme, immunoglobulins, and surfactant, inhibit or eliminate L. fusiformis. If the bacteria reach the alveoli, an inflammatory response is initiated, recruiting alveolar macrophages & neutrophils for phagocytosis. Specific antibodies and cytotoxic T cells are also produced to target and eliminate both L. fusiformis and infected cells.
L. fusiformis has been implicated in causing pathogenicity in humans, particularly associated with tropical ulcer formations and dermal, respiratory infections. The clinical manifestations of L. fusiformis in humans can encompass several concerning outcomes. One prominent manifestation involves the development of painful, deep, and necrotic skin ulcers, often afflicting the lower limbs.
Another serious consequence of L. fusiformis infections is septicemia or blood poisoning. This condition can lead to systemic complications, including shock and organ failure, and, in severe cases, may result in fatality.
Additionally, L. fusiformis has been associated with respiratory tract infections, such as pneumonia, bronchitis, or pharyngitis. The symptoms of these respiratory infections can vary based on the individual immune responses, co-infections, and the availability of suitable treatment options.
Culture test:Lysinibacillus fusiformis can be cultured and isolated from clinical specimens, including blood, sputum, or wound swabs, using standard microbiological techniques. The characteristic colonies of L. fusiformis typically exhibit a white, smooth, & circular appearance on nutrient agar plates, aiding in its identification through visual inspection.
Molecular Methods: Advanced molecular methods, such as PCR (polymerase chain reaction), 16S rRNA sequencing, and matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF MS), offer rapid and accurate detection & identification of L. fusiformis. These techniques are precious when traditional culture and isolation methods may be challenging or less reliable.
Serological Tests: Serological tests, including enzyme-linked immunosorbent assay (ELISA) and immunofluorescence assay (IFA), play a crucial role in diagnosing L. fusiformis infections. These tests detect specific antibodies against L. fusiformis in patient serum, providing indirect evidence of infection. Additionally, serological tests contribute to monitoring the immune response and assessing treatment efficacy.
Oxidase Test and 16S rDNA Sequencing: The oxidase test, which detects the presence of the oxidase enzyme involved in the electron transport chain of aerobic bacteria, confirms Lysinibacillus fusiformis by yielding a positive result. Furthermore, 16S rDNA sequencing analyzes a highly conserved gene found in bacterial ribosomes, enabling accurate identification based on distinctive sequences. L. fusiformis possesses a unique 16S rDNA sequence facilitating precise identification.
Heavy Metal Tolerance Test: The heavy metal tolerance test assesses L. fusiformis‘ ability to thrive in high concentrations of heavy metals like zinc, lead, cadmium, manganese, and copper. As a moderately halophilic bacterium, L. fusiformis exhibits tolerance to up to 100 mM of these metals, providing insights into its environmental adaptability and potential implications for infections.
Emphasize thorough handwashing with soap and water after handling materials or being in proximity to animals that may carry the bacterium.
Implement the use of protective gloves, masks, and clothing, especially in work environments where L. fusiformis may be present, providing an additional barrier against transmission.
Enhance awareness among healthcare workers and public health officials regarding the diagnosis and treatment of L. fusiformis infections, ensuring a proactive response.
Encourage the use of appropriate antibiotics, such as tetracycline, following prescribed regimens to effectively combat L. fusiformis infections, contributing to successful treatment outcomes.
Advocate for maintaining a healthy lifestyle, including a balanced diet and good hygiene practices, to bolster the immune system’s resilience against L. fusiformis infections.
