Cattle co-infection patterns by hemopathogens and their phylogenetic analysis during the tick season in Constantine and Mila, Northeast Algeria.

Tropical theileriosis, babesiosis, and anaplasmosis are the most dominant tick-borne infections in North Africa where they cause significant economic losses in ruminants' industry. The aim of the present work was to study infections and co-infection patterns in 66 cattle with clinical signs of piroplasmosis and/or anaplasmosis in two localities, Beni Hamidene and Grarem Gouga, districts of Constantine and Mila (Northeast of Algeria), respectively. This study was conducted between early May and late September during four years 2017, 2018, 2020, and 2021.

Infection by haemopathogens and tick infestation of sheep during summer season in Constantine region, Northeast Algeria.

A study on tick infestation of 43 sheep with clinical symptoms of piroplasmosis and anaplasmosis was carried out during summer seasons of 2016 and 2017 in 34 sheep flocks from Beni Hamidene locality, district of Constantine, Northeast Algeria. Only animals with clinical symptoms of piroplasmosis and/or anaplasmosis were checked for tick infestation. Among the 43 examined sheep, 58 ± 15% were infested by ticks.

Cross-sectional survey of cattle haemopathogens in Constantine, Northeast Algeria.

This aim of the present study was to estimate the prevalence of haemopathogens in cattle in Beni Hamidene locality, district of Constantine (Νortheastern Algeria). Between June and October 2014, 169 bovines from 25 farms were included in this survey, 32 (18.9%) among them were suspected of piroplasmosis and/or anaplasmosis.

Knowledge, attitude and perception of bovine piroplasmosis by cattle owners in Constantine, North-East of Algeria, using participatory epidemiology.

Cattle piroplasmoses are tick-borne diseases, spread worldwide that cause significant economic losses. A participatory epidemiological study was conducted individually or in focus groups with 73 cattle owners in Beni Hamidene locality (district of Constantine, Algeria). The aim of this study was to study cattle owners' knowledge, attitude and perception on cattle piroplasmosis.

Presence of antibodies against tick-borne encephalitis virus in sheep in Tunisia, North Africa.

Background: Tick-borne encephalitis virus (TBEv) is a flavivirus that circulates in a complex cycle involving small mammals as amplifying hosts and ticks as vectors and reservoirs. The current study aimed to investigate the presence of TBEv in Tunisian sheep. A sample of 263 adult sheep were selected from 6 localities where Ixodes ricinus is well established.
