“…As suggested by Davis et al (2008), the two responses may be dissociated by examining the relative number of circulating monocytes and eosinophils as these cells do not increase in number under stress. A refinement in this diagnostic is also obtained by using cytochemical stains (see Martínez-Silvestre et al, 2005;Tavares-Dias, 2006), which highlight WBC traits (e.g. neutrophil or heterophil toxic granulation, Fig.…”

Blood analyses have great potential in studies of ecology, ecotoxicology and veterinary science in wild vertebrates based on advances in human and domestic animal medicine. The major caveat for field researchers, however, is that the 'rules' for human or domestic animal haematology do not always apply to wildlife. The present overview shows the strengths and limitations of blood analyses in wild vertebrates, and proposes a standardisation of pre-analytical procedures plus some suggestions for a more systematic examination of blood smears to increase the diagnostic value of blood data. By discussing the common problems that field researchers face with blood variables, we also aim to highlight common ground enabling new researchers in the field to accurately collect blood samples and interpret and place their haematological findings into the overall picture of an ecological or eco-toxicological study. Besides showing the practicality and ecological relevance of simple blood variables, this study illustrates the suitability of blood samples for the application of cutting-edge analytical procedures for expanding the current repertoire of diagnostic tools in wildlife monitoring and ecosystem health assessment.

The present study reports the morphology of leukocytes of 12 European lacertid lizards (Podarcis sicula, P. tiliguerta, P. melisellensis, P. bocagei, P. muralis, Algyroides nigropunctatus, Lacerta viridis, L. bilineata, L. trilineata, L. oxycephala, Timon lepidus, and Zootoca vivipara) stained using May-Grünwald/Giemsa method. The morphology of white blood cells was very similar among species, suggesting a relative morphological uniformity within the lacertid lizards. For six species (i.e. P. sicula, P. tiliguerta, P. melisellensis, P. bocagei, P. muralis, and A. nigropunctatus), we determined the leukocyte differential counts, which may be considered representative of the normal values of the corresponding populations. These results may be useful either in clinical investigation to detect pathologies in wild individuals, as in management and conservation projects to assess the general health conditions of natural wild lizard populations.

“…In Iberian and Canarian lacertid lizards, haemogregarines have been recorded from erythrocytes in lizards of the genera Podarcis Wagler (Alvarez-Calvo, 1975;Amo et al, 2005b), Timon Tschudi (Alvarez-Calvo, 1975Amo et al, 2005a), Iberolacerta Arribas (Amo et al, 2004) and Gallotia Boulenger (Bannert et al, 1995;Martínez-Silvestre et al, 2001, 2005. The specific identity of these parasites remains to be elucidated.…”

In Iberian and Canarian lizards, haemogregarines have been recorded infecting erythrocytes, but most of the records correspond to mature gametocytes. We analysed blood smears from 75 specimens of Podarcis bocagei (Seoane) and 33 specimens of P. carbonelli (Pérez-Mellado) from localities of north-western Portugal. We found haemogregarines in 74.7% of P. bocagei and 69.7% of P. carbonelli. Our observations show characteristics of the haemogregarines other than the morphology of the mature gametocytes. In histological sections of the liver of four hosts latent cysts with sporozoites and meronts with merozoites were detected. Both traits have been described as typical of the genera Hepatozoon Miller, 1908 and Hemolivia Petit, Landau, Baccam & Lainson, 1990. We suggest that not only P. bocagei and P. carbonelli from Portugal but other species of Iberian and Canarian lacertids might also be infected by species belonging to one or both genera.
