Sheep ectoparasites such as chewing lice, fleas and ticks are serious constraints to sheep productivity and are the cause of skin lesions in animals that decrease their market value. This study aims at investigating the ectoparasite fauna infesting small ruminants in the district of Sidi Bouzid (central Tunisia). A total of 1243 Barbarine and Queue...

Ticks are blood-sucking ectoparasites and can transmit various pathogens of medical and veterinary relevance. The life cycle of ticks can be completed under laboratory conditions on experimental animals, but the artificial feeding of ticks has attracted increased interest as an alternative method. This study represents the first report on the succe...

Full-text available
Theileria annulata is a protozoan parasite with a complex life cycle involving a bovine host and a tick vector. It is transmitted by Hyalomma ticks and is the causative agent of tropical theileriosis, a debilitating and often fatal disease in southern Europe, northern Africa and large parts of Asia. Understanding the biology of different life cycle...
Article
Full-text available
The apicomplexan parasite Theileria annulata is transmitted by Hyalomma ticks and causes an acute lymphoproliferative disease that is invariably lethal in exotic cattle breeds. The unique ability of the schizont stage of T. annulata to transform infected leukocytes to a cancer-like phenotype and the simplicity of culturing and passaging T. annulata...
Article

Ticks are important ectoparasites responsible for the transmission of several pathogens with significant medical, veterinary, and economic impacts. Climate and social changes have generated substantial changes in ticks’ distribution, abundance, and activity patterns, including ticks belonging to the Hyalomma marginatum species. Knowledge on the gen...

Background Tropical theileriosis, Theileria annulata infection, is the most prevalent summer disease in Tunisia. It is transmitted by Hyalomma scupense, a two‐host tick known to be endophilic. Objectives The present study aimed to estimate the infection prevalence of cattle by T. annulata in two districts from central Tunisia. Methods Blood sampl...

Introduction Tropical theileriosis is a protozoan disease caused by Theileria annulata that affects cattle in Northern Africa, the Middle East and Asia where vector ticks of the genus Hyalomma occur. Various measures are applied to control the disease, including vaccination with attenuated T. annulata schizonts. Cultivation of T. annulata schizonts...

African buffalo (Syncerus caffer) have been distinct from the Auroch lineage leading to domestic cattle for 5 million years, and are reservoirs of multiple pathogens, that affect introduced domestic cattle. To date, there has been no analysis of the class I MHC locus in African buffalo. We present the first data on African buffalo class I MHC, whic...
Article
The present study aimed to investigate the activity dynamics of Ixodes ricinus group ticks in a forest located in north-western Tunisia (Aïn Draham, Jendouba District) and assess the variation of abiotic factors (temperature, Normalized Difference Vegetation Index and relative humidity) during one year survey from September 2016 to August 2017 usin...

Full-text available
Theileria annulata is a tick‐borne protozoan causing tropical theileriosis in cattle. The use of attenuated cell line vaccines in combination with subunit vaccines has been relatively successful as a control method, as exemplified by a recent study in which immunization with a local cell line followed by booster vaccinations with recombinant T. ann...

In this study, we report the results of a survey of Hyalomma ticks infesting one-humped camels in southern Tunisia. Examinations were conducted every second or third month on 406 camels in Tataouine district from April 2018 to October 2019. A total of 1902 ticks belonging to the genus Hyalomma were collected. The ticks were identified as adult H. i...
Presentation
Ticks (Acari, Ixodidae) belonging to the genus Hyalomma, such as Hyalomma dromedarii Koch 1844, Hyalomma impeltatum Schulze & Schlottke, 1930 and Hyalomma excavatum Koch, 1844 are the main species infesting one-humped camels in extensive production systems in arid and Saharan regions of south Tunisia and are vectors of several pathogens including C...

Theileria annulata is a tick-borne protozoan causing tropical theileriosis (TT) in cattle in the Mediterranean region. Control efforts are constrained by the emergence of resistance to chemotherapy by some T. annulata strains and acaricide resistance by the tick vector. It has been demonstrated in Sudan that vaccination using T. annulata infected c...
Article
Full-text available
Distinct pathogenic and epidemiological features underlie different Theileria parva strains resulting in different clinical manifestations of East Coast Fever and Corridor Disease in susceptible cattle. Unclear delineation of these strains limits the control of these diseases in endemic areas. Hence, an accurate characterization of strains can impr...

Crimean-Congo haemorrhagic fever is a viral tick-borne zoonotic disease caused by a Nairovirus, Crimean-Congo haemorrhagic fever virus (CCHFV). The present survey aimed to determine the exposure of one-humped camels (Camelus dromedarius) from southern Tunisia to CCHFV. A total of 273 sera from extensively reared camels were collected from Tataouine...

Tropical theileriosis caused by the apicomplexan hemoparasite Theileria annulata is a tick‐borne disease that constraints livestock production in parts of Europe, Asia and Africa. Four Hyalomma tick species transmit T. annulata in at least eight Africa countries (Mauritania, Morocco, Algeria, Tunisia, Egypt, Sudan, South Sudan and Ethiopia). The tw...

Different infestation patterns by ixodid ticks were studied in three sheep breeds in Tunisia: Barbarine, Queue Fine de l'Ouest and their cross-bred animals. During one year, 700 sheep were monitored and examined for tick infestation. A total of 722 ticks were collected from sheep ears. The most frequent tick species was by far Rhipicephalus sanguin...

This study aimed to determine tick population dynamics infesting sheep in Gafsa region (Central Tunisia). Ticks were collected monthly over a year, from October 2013 to September 2014, from 57–64 randomly-included Barbarine-breed sheep. In total, 560 ticks were collected and identified. They belonged to two species: Rhipicephalus sanguineus sensu l...

This survey was conducted during one year on 117 donkeys slaughtered in Tunis’s slaughter house. A total of 4536 larvae were collected consisting of four Gasterophilus species. The population was dominated by G. intestinalis (49.6%±9) followed by G. pecorum (31.6%±8.4), G. inermis (17.9%±7) and G. nasalis (14.5%±6.3) (p<0.005). The infestation prev...
