Genotyping Reveals Potential Sources of Human Leptospirosis Outbreaks in Aotearoa New Zealand

Zoonoses and Public Health, Volume 73, Issue 1, Page 54-64, February 2026.
ABSTRACT Introduction The introduction of PCR testing for leptospirosis in Aotearoa New Zealand has reduced the availability of serotyping data, and current diagnostic PCRs do not routinely genotype Leptospira. This study genotyped Leptospira from PCR‐confirmed human cases between 2016 and 2023 and compared them with genotypes found in animals to ...

Visual proteomics of the human pathogen Leptospira interrogans [PDF]

Nature Methods, 2009
Systems biology conceptualizes biological systems as dynamic networks of interacting elements, whereby functionally important properties are thought to emerge from the structure of such networks. Owing to the ubiquitous role of complexes of interacting proteins in biological systems, their subunit composition and temporal and spatial arrangement within

TheLeptospira interrogans lexAGene Is Not Autoregulated [PDF]

Journal of Bacteriology, 2005
ABSTRACTFootprinting and mutagenesis experiments demonstrated thatLeptospira interrogansLexA binds the palindrome TTTGN5CAAA found in therecApromoter but not in thelexApromoter. In silico analysis revealed that none of the other canonical SOS genes is under direct control of LexA, making the leptospirallexAgene the first described which is not ...

Epidemiological investigation into abortion in farmed red deer in New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Veterinary Sciences at Massey University, Palmerston North, New Zealand [PDF]

, 2016
Reproductive performance in rising two-year-old (R2) and mixed-aged (MA) adult hinds is suboptimal in farmed red deer in New Zealand due to failure to conceive, fetal loss, and perinatal and postnatal mortality.

Evaluation of Laboratory Techniques for the Diagnosis of Leptospira‐Associated Equine Recurrent Uveitis (ERU) With Focus on the Goldmann‐Witmer Coefficient

Veterinary Ophthalmology, Volume 29, Issue 1, January 2026.
ABSTRACT Purpose To evaluate different laboratory procedures for determining the etiologic diagnosis of equine recurrent uveitis regarding intraocular infection with Leptospira spp. and to establish a diagnostic guideline. Material and Methods Eighty horses with a history of ERU were ophthalmologically examined.

Genetic affinities within a large global collection of pathogenic Leptospira: implications for strain identification and molecular epidemiology [PDF]

, 2010
Leptospirosis is an important zoonosis with widespread human health implications. The non-availability of accurate identification methods for the individualization of different Leptospira for outbreak investigations poses bountiful problems in the ...

Host‐Driven Genetic Diversity of Leptospira in the Americas: A Continental Perspective

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Leptospira is a genetically diverse genus of spirochetes comprising over 68 species, including several pathogenic taxa such as L. interrogans, L. santarosai, L. noguchii, and L. weilii. These bacteria infect a wide range of vertebrates, especially mammals, with infected animals serving as renal carriers that excrete the pathogen through urine.
