Prevalence and Molecular Characterization of Methicillin-Resistant Staphylococci (MRS) and Mammaliicocci (MRM) in Dromedary Camels from Algeria: First Detection of SCC- Hybrid in Methicillin-Resistant .

Dromedary camels are an important source of food and income in many countries. However, it has been largely overlooked that they can also transmit antibiotic-resistant bacteria. The aim of this study was to identify the bacteria composition of the nasal flora in dromedary camels and evaluate the presence of methicillin-resistant (MRM) and methicillin-resistant (MRS) in dromedary camels in Algeria.

Assessing hygiene indicators in two dairies in Algeria in producing pasteurized milk.

Background And Aim: There is a worldwide controversy about the choice of microbial flora for use as process hygiene indicators. This study aimed to evaluate the pertinence of using either coliforms or Enterobacteriaceae (EB) as process hygiene indicators in the pasteurized milk production line. Two flora families and total flora were used as bacterial indicators in some stages of pasteurized milk production line to identify the origin of post-pasteurization contamination and compare the results obtained for each flora.

Health risk assessment of exposure to polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (DL-PCBs) in swordfish from the Mediterranean Sea.

Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (DL-PCBs) in fish samples have been investigated in many previous studies. However, the available data regarding this issue in low- and middle-income countries are very scarce, and no study has been performed in Algeria yet. Therefore, this work aimed to determine the levels of PCDD/Fs and DL-PCBs in swordfish (Xiphias gladius) caught in three regions of the Algerian coasts, and the health risk associated with these contaminants was assessed.

Analysis and risk assessment of arsenic, cadmium and lead in two fish species ( and ) from Algerian coastal water.

In this study, the levels of arsenic (As), cadmium (Cd) and lead (Pb) have been determined in the flesh of two species of fish, sardine () and swordfish () fished in the Algerian coast. Quantification of As, Cd and Pb was carried out using an ICP-MS method and the results were compared with the thresholds set by national and international regulatory bodies. In a further step, the risk to consumers was assessed using estimated daily intake (EDI), target hazard quotient (THQ) and hazard index (HI).

Influence of some parameters on the ability of , , and to form biofilms.

Aim: The present study was conducted to evaluate the capacity of (L.m), (L.i), and to form biofilms on polystyrene support under different parameters by performing crystal violet (CV) staining technique.

isolated from selected dairies of Algeria: Prevalence and susceptibility to antibiotics.

Aim: The objectives of this study were to assess the prevalence of in raw milk in Algerian dairies, to study the effect of seasons on the contamination of milk and the susceptibility of isolated strains to antibiotics, and to estimate the risk on the health consumer.

Materials And Methods: The ISO method 6888-1 (1) was used for screening. Antimicrobial susceptibility to the 11most used antibiotics in veterinary medicine was assessed using the disk diffusion assay.

Evaluation of the heavy metals (mercury, lead, and cadmium) contamination of sardine () and swordfish () fished in three Algerian coasts.

Aim: This study aimed to evaluate mercury (Hg), cadmium (Cd), and lead (Pb) levels in 70 samples of sardine () and 30 samples of swordfish () fished in the Algerian coasts.

Materials And Methods: After the mineralization of the fish samples through the pressure digestion, the analyses were carried out by inductively coupled plasma atomic emission spectroscopy.

Results: Mean concentrations of Hg, Cd, and Pb in sardine were 0.

Sources of contamination, prevalence, and antimicrobial resistance of thermophilic isolated from turkeys.

Aim: Sources of contamination, prevalence, and antimicrobial susceptibility of thermophilic isolated from turkey samples were determined.

Materials And Methods: A total of 300 samples were collected from 3 farms (fecal droppings) and 4 poultry slaughterhouses (neck skins and ceca) located in the middle area of Algeria (Algiers, Boumerdès, and Bouira). After detection, an antibiogram was realized only for slaughterhouses samples.

Prevalence of Listeria spp. and Molecular Characterization of Listeria monocytogenes Isolates from Broilers at the Abattoir.

Products from three broiler abattoirs were sampled for Listeria species to evaluate the changes in the prevalence and contamination rates at two stages of processing. Sampling was performed at the evisceration stage and at the end of processing after packaging and refrigerating at 4°C for 24 h. A total of 212 samples were collected; 52 were from abattoir A, and 80 samples each were collected from abattoirs B and C.
