The deleterious effects of the residues of antibacterial drugs have been considered as one of the most serious problems in the world on the basis of their importance in both veterinary and human fields. Therefore, the present study was planned out to evaluate the residual levels of oxytetracycline in camel tissues in Tripoli area in Libya. Forty samples of slaughtered camel's tissues (10 of muscle, 10 of liver, 10 of kidney, and 10 of fat) were collected from different carcasses at different slaughter houses in Tripoli districts. The samples were homogenized, extracted and residual concentrations of oxytetracycline have been measured using liquid chromatography-Mass spectroscopy (LC-MS) technique and oxytetracycline standard. Oxytetracycline residues have been detected in 60% in muscle, 80% in liver, 90% in kidney and 70% in fat samples. The samples, although positive, yet decided acceptable as the detected levels were less than that were regulated by Codex Alimentarius Commission (CAC) for oxytetracycline maximal residual levels (100, 300, 600 and 100 μg/Kg muscle, liver, kidney or fat, respectively). The authors recommended avoiding irrational use of oxytetracycline in veterinary practice and camel in particular; and sticking to the withdrawal time regulated and labelled for drugs used in therapy among veterinary personnel, organizations, and governmental agencies in Libya.

This study aimed to evaluate the antibacterial activity of flavonoids extracted from two Libyan brown algae namely Cystoseira compressa and Padina pavonica using microwave-assisted extraction method against pathogenic bacteria isolated from meat, meat products, milk and dairy products (Staphylococcus aureus subsp. aureus (5 isolates), Bacillus cereus (3 isolates), Bacillus pumilus (1 isolate), Salmonella enterica subsp. enteric (4 isolates) and Enterohaemor-rhagic Escherichia coli O157 (EHEC O157) (4 isolates)). All of these isolates were muti-drug resistant with high MAR index. The results showed that C. compressa extract exhibited better and stronger antibacterial activities against the seventeen tested isolates with inhibition zones diameter ranged from 14 - 22 mm compared to P. pavonica extract which showed positive effect against 9 isolates with low inhibition zone ranged from 11 - 16.5 mm. Flavonoids extracted from C. compressa also displayed the best spectrum of bactericidal effect with a ratio MBC/MIC ≤ 4 obtained on all susceptible tested bacterial strains. Flavonoids and proanthocyanidins significantly contributed to the antibacterial properties. The mode of action of these active extracts is under investigation.

Understanding the publication output of a country’s biomedical research can provide information for strengthening its policies, economy, and educational systems. Yet, this is the first bibliometric study to date to analyze and provide an in-depth discussion of the biomedical research productivity from Libyan academic institutions. The biomedical research productivity of higher education institutes and affiliated hospitals from Libya, with a focus on the higher education sector, was analyzed and discussed for the period of 2003–13 using the PubMed database. A questionnaire online survey was also developed to obtain opinions of Libyan scientists on productivity status and quality of research output. A total of 345 peer-reviewed articles were included in the analysis and were authored by researchers in the cities of Benghazi (32%), Tripoli (29%), Al-Zawiya (9%), Al-Bayda (8%), Sabha (3%), Misrata (3%), and Al-Khoms (1%). The papers included co-authors and/or corresponding authors from over 40 other countries were published in 179 journals covering a broad range of biomedical topics. Questionnaire (44% response rate) indicated research is largely self-funded. Information along with accurate, comprehensive, and transparent metrics can be applied to aid governmental and nongovernmental institutions to develop stable infrastructures for academic communities to achieve effective research performance and innovation.
