Hydrogeological Data

Geophysical data combined with geological and hydrogeological data were analyzed to characterize the geometry of Oued El Hajel and Ouled Asker deep water tables (Sidi Bouzid). The obtained results allowed refining the geostructural schema by highlighting the individualization of the NE-SW underground convexity of Ouled Asker and the anticline of axis Es Souda-Hmaeima and Ezaouia on either sides of two hydrogeological thresholds. The geometrical analysis determined the spatial extension of Ouled Asker and Oued El Hajel subbasins. The seismic cartography of semideep and deep reservoirs (Oligo-Miocene; Eocene and upper Cretaceous) associated with the main subbasins contributed to proposing hydrogeological prospect zones for a rationalized groundwater exploitation.

SUMMARYIn this study, the prevalence of piroplasms in dogs was assessed using polymerase chain reaction (PCR) to identifyBabesiaandTheileriaspecies in 200 dogs from Northern and Central Tunisia between spring and autumn 2014. The overall molecular prevalence for piroplasms was 14·5% ± 0·05 (29/200); PCR detected 2 species, namelyBabesia vogeliandTheileria annulatawith an overall prevalence of 12·5 ± 0·04 and 2% ± 0·02, respectively. No differences in the molecular prevalences ofB. vogeliwere revealed for age and sex (P> 0·05). The molecular prevalence ofB. vogeliwas significantly higher in central Tunisia (26·5% ± 0·01) compared with the North (9·6% ± 0·04) (P< 0·05). More working and companion dogs were infected byB. vogeli(25·8 ± 0·15 and 21·1% ± 0·13, respectively) in comparison with guarding dogs (1·8% ± 0·03) (P< 0·05). ConcerningT. annulata,no significant variation was observed for all studied risk factors (P> 0·05). Comparison of the partial sequences of18S rRNAandTams 1genes confirmed the presence of 2 novelB. vogeliandT. annulatagenotypes. This is the first molecular detection ofT. annulataand genetic characterization of dogs’ piroplasms in Tunisia. Further studies are needed to better assess the epidemiological feature of piroplasms infection in North Africa.
