Haemoparasites in red-legged partridge (Alectoris rufa): first record of Haemoproteus sp. in Italy?

During a health survey in the Province of Alessandria (NW Italy) 267 free ranging red-legged partridge ( Alectoris rufa ; 137 males and 130 females) were captured in 2009 (n = 101), 2010 (n = 130) and 2011 (n = 36). After biometric data and blood samples collection, animals were released on site. Bl...

Zusammenfassung:During a health survey in the Province of Alessandria (NW Italy) 267 free ranging red-legged partridge ( Alectoris rufa ; 137 males and 130 females) were captured in 2009 (n = 101), 2010 (n = 130) and 2011 (n = 36). After biometric data and blood samples collection, animals were released on site. Blood samples were used for the preparation of blood smears. A total of 1.5% of smears presented parasites with a light blue finely granular cytoplasm in red blood cells. The parasites were identified, on the basis of their morphology (no molecular identification was possible), as being Haemoproteus sp. juvenile forms. The infestation prevalence was 0.8% in 2010 and 8.3% in 2011. No parasite was observed in 2009. The size of the infested erythrocytes was not altered ( P  > 0.05) and the nuclear displacement ratio was 0.8 ± 0.2. All the birds were apparently in good health status. To our knowledge this is the first description of Haemoproteus sp. in red-legged partridge, and more in general in birds belonging to Galliformes Order in Italy.
