Food safety is a big challenge that concern all human communities and food production factories. The information on the bacterial evaluations of fresh natural juices in the city of Benghazi remained very limited and unclear. This study was carried out to evaluate the bacterial contamination for two of the most popular selling freshly made juices, including mango and strawberry juices. The results of screening showed bacterial growth in 117 (91.41%) out of the total samples 128. The evaluation during the second season showed a higher bacterial growth rate of 96.55 %. The most predominant bacteria contaminating the targeted juices was Klebsiella pneumoniae, with an average of (36.21%), followed by fecal Escherichia coli (31.03%) for both juices. All the contaminated juices represented bacteria count out of the accepted value. Gram-negative pathogens showed resistance to limited antibiotics, including Amoxicillin, Amikacin, and Clarithromycin, whereas the Gram-positive bacteria showed higher resistance rates. This study concluded that, increase in bacterial diversity and bacterial count out of the accepted standard as well as the presence of fecal E. coli indicating a poor level of hygiene during the process of preparing juices, leading to the possibility of causing diseases and exposing people to food poisoning.
The Plants of the genus Fagonia have been broadly utilized as adjunctive therapy, to treat several conditions involving high fever, diabetes, asthma, stoma chache, dental pain, and renal problems using their aqueous extracts as medicines. This genus is a valuable source that comprises a variety of Triterpenes, flavonoids, and Saponins. The herbal chemistry as well as the biological action of Fagonia species have been a candidate for many researchers. The in vivo pharmacological screening of their extracts has manifested some other significant properties such as cytotoxic and anti-cancer activity. This review study has gathered the important research that has been carried out on the species that grow in Libya. It includes an exhaustive survey of literature about the medicinal value and the bioactivities of various extracts obtained from these Fagonia species using references from major databases.
Human cytomegalovirus (HCMV) is a ubiquitous DNA-containing herpesvirus causes severe and fatal diseases in immunocompromised patients and a prevalent cause of virus-associated birth defects. Blood transfusion donated for neonates, pregnant women, and immunocompromised patients should be adequately screened for evidences of CMV infection prior to use in clinical management. The effective national programmes for quality-assured screening of donated blood have not yet been fully established, hence this study was undertaken to assess whether any bloodborne-CMV infections pose a significant threat to the safety of the blood supplies. A total of 200 voluntary blood donor subjects admitted to the Blood Bank of Benghazi/Libya were screened for transfusion-transmissible CMV (TT-CMV) using a highly sensitive CMV total IgG and IgM antibody enzyme immunoassay as well as CMV pp65 antigenemia assays. We determined that the overall seropositivity for IgG antibodies (80.50%) was higher than that of IgM antibodies (39.00%), but only 2 (1.00%) individuals out of these donors were seropositive for the CMV-antigenic protein pp65. The frequency of CMV infection based on gender was incomparable due to the small population number of blood-donated females. According to age, there was not influence of various age groups on prevalence of anti-CMV IgG antibodies, while a progressive increase in seropositivity of CMV-IgM antibodies with age was detected. The age groups were not significantly associated with CMV prevalence. In contrast, only 2 (1.00%) patients were shown to be positive for all three performed assays indicating a recurrent infection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
