Serological surveillance of Leptospirosis in Italy: two‑year national data (2010‑2011).

Abstract: Nowadays, leptospirosis is a re‑emerging widespread infectious disease often underestimate worldwide. The National Reference Centre for Leptospirosis (NRCL), at the Istituto Zooprofilattico Sperimentale della Lombardia e dell'Emilia Romagna, Brescia (Italy), with the cooperation of all the other Istituti Zooprofilattici Sperimentali (IIZZSS), evaluated the distribution of such important zoonosis in Italy. Serological data obtained between 2010‑2011 by each laboratory were collected by the NRCL and discussed. Serum samples collected from 43,935 animal specimens were analysed by the Microscopic Agglutination Test (MAT), using a panel of 8 serogroups as antigens (Australis, Ballum, Canicola, Grippotyphosa, Icterohaemorrhagiae, Pomona, Sejroe, Tarassovi). A MAT cut‑off of 1:100 was used to identify the serological positivities, 6,279 sera showed positive titers. Bovine (46.9%), swine (27.5%), ovine and goat (7.4%), dog (6.9%), and wild boar (4.5%) samples were delivered to the Laboratories more frequently than equine and other species sera. Data analysis showed that the most common serogroups in Italy are: Australis present in dogs, wild boars, horses, hares, swine, foxes, and rodents; Sejroe detected in cattle, sheep, goats, and buffaloes; Icterohaemorrhagiae present in dogs, goats, and foxes; Pomona detected in swine, cattle, and wild species; Grippotyphosa reported in hares.

The research explores the prevalence of Leptospirosis, a widespread, often underestimated infectious disease, in Italy. Using data from the National Reference Centre for Leptospirosis (NRCL), the paper analyzes serological data from serum samples collected between 2010-2011.

Objective of the Research

  • The research aimed to evaluate the distribution of Leptospirosis in Italy, an infectious disease that is re-emerging and often underestimated worldwide.

Methodology

  • For the study, the NRCL, along with other Istituti Zooprofilattici Sperimentali, collected and analyzed serological data between 2010 and 2011.
  • Around 43,935 animal samples, including bovine, swine, ovine, goat, dog, wild boar, etc., were tested using the Microscopic Agglutination Test (MAT) method.
  • The test used antigens from 8 serogroups including Australis, Ballum, Canicola, Grippotyphosa, Icterohaemorrhagiae, Pomona, Sejroe, and Tarassovi.
  • A MAT cut-off of 1:100 was used to identify serological positives, finding 6,279 sera with positive titers.

Findings

  • The research discovered that leptospirosis is quite common in Italy, with the most common serogroups being: Australis present in dogs, wild boars, horses, swine, foxes, and rodents; Sejroe detected in cattle, sheep, goats, and buffaloes; Icterohaemorrhagiae present in dogs, goats, and foxes; Pomona detected in swine, cattle, and wild species; Grippotyphosa reported in hares.
  • The animals most frequently delivered to the Laboratories were bovine (46.9%), swine (27.5%), ovine and goat (7.4%), dog (6.9%), and wild boar (4.5%) samples with equine and other species showing lesser frequency.
