Theileria species are tick-borne, intracellular apicomplexan protozoan parasites that pose a significant threat to livestock health and productivity. Theileria orientalis, the etiological agent of oriental theileriosis, is a benign Theileria species with worldwide distribution, including Algeria, where investigations on its prevalence and genetic d...

For over a century, researchers have grappled with a compelling question: can ticks act as vectors for Trypanosomatidae parasites, such as Trypanosoma and Leishmania species, which pose significant threats to human and animal health? A recent systematic review and meta-analysis provides new evidence that could reshape our understanding of tick-born...

Bluetongue (BT) is a vector-borne disease affecting wild and domestic ruminants in many parts of the world. Although bluetongue virus (BTV) is widespread in ungulates in Africa, available epidemiological information on BT in this continent is limited. This systematic review and meta-analysis aimed to estimate the seroprevalence of BTV and summarize...

Since the 20th century, numerous studies have detected or isolated parasites from the Trypanosomatidae family in various tick species. However, the status of ticks as vectors of medically or veterinary important Trypanosoma and Leishmania remains unclear. We conducted a systematic review and meta-analysis to provide new insights into the potential...

Domestic dogs and cats can serve as a source of environmental contamination with Toxocara spp. and Blastocystis spp., and this represents a neglected public and veterinary health problem. We assessed the microscopic and molecular prevalence of these species in a locality in Algeria and identified the associated risk factors. The faeces of 225 dogs...

Coxiella burnetii, or Q fever agent, has notable implications for human and livestock health. Infections in cattle primarily manifest through reproductive issues where infected animals shed the bacterium in birth fluids, placental tissues, and milk, serving as potential sources of transmission. Bovine herds become reservoirs, contributing to the en...

Nepovirus Grapevine FanLeaf Virus (GFLV) is among the viruses that cause the infectious degeneration of grapevines. It is transmitted by the ectoparasitic nematode Xiphenema index. This study aimed to investigate the GFLV virus in 25 vineyards located in north-central Algeria and occupied by nine different grape varieties. Several surveys were carr...

Toscana virus is a sandfly-borne human pathogen belonging to Phlebovirus genus into Phenuiviridae family. It is emerging in north Africa posing a complex threat to public health. TOSV is heavily affecting sandfly-exposed people in northern Algeria. A larger distribution has recently been stated in Algeria by using dog sera. Dog exposure to TOSV was...

This work aims to determine the main histological changes in the endometrium of female camels during the postpartum period (recovered from the uterine epithelium). For this, successive samples of uterine mucosa were taken from the left uterine horn of females from the 3rd, 5th, 7th, 11th, 15th, 18th, and 21st postpartum day. The samples of the uter...

Toscana virus (TOSV) is major meningitis and meningoencephalitis agent in the Mediterranean basin. Dogs are frequently exposed to TOSV; thereby they can contribute to estimating its circulation. In Algeria, little is known about its circulation, and available data are restricted to the Kabylian region. To investigate the current situation in Algeri...

The present study aimed to determine the phenology and predilection sites of ticks infesting cattle in the western region of Djurdjura (North Algeria) from November 2018 and October 2020. Nineteen cattle farms located in thirteen localities within four provinces were visited monthly for two years. Among the 289 examined cattle, 64.36 ± 2.81% (n=189...

The prevalence and risk factors associated with gastrointestinal parasites in dogs were conducted in Blida, North-Central Algeria. The study was carried out over 131clinically healthy dogs, from March to June 2019, by coprological methods. Of the 131 collected dogs, 61.07% (n=80) were found infected by gastrointestinal parasites. Sixty-four dogs we...

Our work is a survey of 35 dairy cattle farms located in three towns in the province of Constantine. The one-pass survey lasted 6 months, from October 2010 to April 2011. The purpose was to characterize the diversity of these farms, and to understand the problems related to their location, infrastructures, equipment, and the process of the dairy wo...

To understand the prevalence and characteristics of Staphylococci causing goat mastitis in Algeria, mastitis milk samples were collected and cultured on both blood agar and mannitol salt agar medium. Staphylococci isolates were identified by API-Staph gallery and tested for antibiotic susceptibility by disk diffusion method. DNA microarrays analysi...
