RESUMO
Hepatitis E is an acute self-limited or fulminant infection in humans, caused by the hepatitis E virus (HEV). This member of the Hepeviridae family has been identified in a wide range of domestic and wild animals all over the world, with a possible transmission to humans through fecal oral route, direct contact and ingestion of contaminated meat products, making it one of the global zoonotic and public health major concerns. Since there is no monitoring program and a lack of data on HEV in animals in Algeria, the current preliminary survey has been undertaken to elucidate the exposure to the virus in camels at abattoirs of six southern provinces of Algeria. Two-hundred and eight sera/plasma were collected and analyzed (by double antigen sandwich ELISA) for the presence of total anti-HEV antibodies, among which 35.1% were positive, but no HEV RNA could be isolated from them (by two pan-HEV nested RT-PCR and broad range real-time reverse transcription RT-PCR). The univariate analysis showed significant associations (p < 0.05) between HEV seroprevalence and province of origin, age, and sex of camels, whereas the multivariable logistic regression analysis revealed a negative impact of camels' age on it. The obtained results confirm that HEV infection is widespread established in the camelid population of Algeria.
RESUMO
OBJECTIVE: This work aimed to determine the resistance and/or the susceptibility to antibiotics of staphylococci isolated from cattle with mastitis in the North of Algeria. MATERIALS AND METHODS: The disk diffusion method was carried out to reveal the antibiotic resistance in accordance to the National Committee for Clinical Laboratory Standards guidelines in the Mueller-Hinton agar. RESULTS: Coagulase-negative Staphylococci (CNS) isolates showed more resistance to Cefoxitin, Amoxicillin + Clavulanic Acid, Vancomycin, Trimethoprime Sulfamethoxazole, Clindamycine, Neomycin, and Erythromycin than Coagulase-positive Staphylococci (CPS). CPS were more resistant to Penicillin and Tetracycline as compared to CNS strains; however, all these strains presented sensitivity to Gentamicin and neomycin. CONCLUSION: The Staphylococci showed high resistance to the beta-lactam antibiotics. As far as the authors know, these molecules are used with or without control in different protocols to prevent and cure the mastitis in Algeria.
