Identification, geographic distribution and risk factors of Brucella abortus and Brucella melitensis infection in cattle in Algeria.

Brucellosis is an infectious disease of several terrestrial and marine animals and humans caused by bacteria of the genus Brucella. This study aimed to identify Brucella species and biovars circulating in cattle and to analyze their geographic distribution across Algeria. Two hundred ninety eight milk and lymph node samples from 161 seropositive cattle of different local and foreign breeds were collected from 97 dairy farms in 56 towns of 13 wilayas (states/ provinces) of the central, eastern, western and southern regions.

Bovine herpesvirus 1 in the northeast of Algiers, Algeria: Seroprevalence and associated risk factors in dairy herd.

Objective: The present study was conducted to estimate the seroprevalence and associated risk factors of bovine herpesvirus 1 (BoHV-1) in a dairy herd in the northeast of Algiers, Algeria.

Materials And Methods: The target area is in the northeast of Algiers with humid to semi-dry climate and known for its economically important production of cattle. A total of 1,066 randomly selected individual blood samples of dairy herd collected at 120 dairy farms from rural districts of northeast of Algiers were evaluated with antibodies against BoHV-1 using commercial enzyme-linked immunosorbent assay kits, to determine the BoHV-1 infection status of the herds.

Seroprevalence of border disease virus and other pestiviruses in sheep in Algeria and associated risk factors.

Background: Border disease virus (BDV) is a pestivirus responsible for significant economic losses in sheep industry. The present study was conducted between 2015 and 2016 to determine the flock seroprevalence of the disease in Algeria and to identify associated risk factors. 56 flocks from nine departments were visited and 689 blood samples were collected from adult sheep between 6 and 24 months of age (n = 576) and from lambs younger than 6 months (n = 113).

Serological and molecular evidence of Q fever among small ruminant flocks in Algeria.

Q fever, a commonly reported zoonosis worldwide, is caused by infection with Coxiella burnetii, an obligate intracellular bacterium. The infection is often asymptomatic in ruminants, but it can lead to reproductive disorders with bacterial shedding into the environment. Between 2011 and 2013, a study was undertaken in small ruminant flocks in different regions of Algeria.

Human brucellosis in Maghreb: existence of a lineage related to socio-historical connections with Europe.

Despite control/eradication programs, brucellosis, major worldwide zoonosis due to the Brucella genus, is endemic in Northern Africa and remains a major public health problem in the Maghreb region (Algeria/Morocco/Tunisia). Brucella melitensis biovar 3 is mostly involved in human infections and infects mainly small ruminants. Human and animal brucellosis occurrence in the Maghreb seems still underestimated and its epidemiological situation remains hazy.

Detection and genotyping of Chlamydia species responsible for reproductive disorders in Algerian small ruminants.

Chlamydiosis in small ruminants is a zoonotic disease mainly related to Chlamydia abortus. This bacterium is responsible for abortions and reproductive disorders in sheep and goats. Stillbirth and infertility, leading to important economic losses, are also associated with this pathology.

[Intracranial pneumatocele secondary to fronto-ethmoidal osteoma. Apropos of a case].

The authors report a case of spontaneous pneumatocele consecutive fronto-ethmoidal osteoma which was unrecognized until its complication. This cases illustrated the interest of the CT scan for the topographie diagnostic of the pneumatocele and the visualization of the osteomeduremerienne breache.
