Bacteriocin Typing of Staphylococcus Aureus Isolated from Different Sources in Ibb City , Yemen

Abstract

A total of 207 specimens were collected from different sources including patients, health care staff and hospital environment in Ibb city, Yemen. The study used the bacteriocin produced from active producer strains in typing of Staphylococcus aureus. Depending on the morphological, cultural and biochemical characteristics, 54 (26.09%) isolates of Staphylococcus aureus were identified. An antibiotic sensitivity test was done for the bacterial isolates, and the results showed that there were multiple resistant antibiotics. The Staphylococcin production of these isolates has been detected by using wells assay. Fifty one isolates were Staphylococcin producer. Four isolates (staph19, staph25, staph28 and staph43) were chosen as good Staphylococcin producers, and used locally as indicators in bacteriocin typing. Depending on S. aureus typing, the isolates fell into (9) groups. The most numerous group was characterized by susceptibility to all four staphylococcin and comprised 61.11% isolates of S. aureus, while the lowest numerous were found in three groups with a ratio of 1.85%; the remaining groups had little percentages ranging from 3.70% to 11.11%. We observed that about (94.44%) of the isolates were bacteriocin producers, and among them, four isolates had a strong bacteriocin production. Based on typing, most isolates had one pattern.

Prevalence of Urinary Tract Infections and Associated Risk Factors Among Patients Attending Medical City Hospital in Baghdad City, Iraq

“…However, the higher rate of staphylococcus was observed in another previous study compared to our study (Awasthi et al, 2015). These disparities in etiologic agents could be because of the different bacterial ecology in different regions, different lifestyle, hygienic conditions, availability of education, inadequate water availability and sample size (Al- Gosha'ah et al, 2014). The other common isolate was Enterococcus faecalis 8/63(12.70%).…”

Impact of Khat Chewing on Serum Uric Acid and Albuminuria Levels in Yemeni Type II Diabetes Mellitus Patients

“…According to reports, UA protects erythrocytes against singlet oxygen damage, reduces lipid peroxidation, and protects against free radical-induced DNA damage in vitro [46]. ROS and oxidative stress have been shown to reduce antioxidant enzyme activity in rats fed Khat [47,48] and in the plasma of female Khat chewers [49]. in this study, Uric acid in Kat Chewers significantly increased within the normal range than Non-Kat Chewers in case and control groups (p ˂0.05) (Table 3), due to a natural reaction to Khat's generation of oxidants and indicates a high frequency of arthritis in (DKC).…”

Antioxidant and antibacterial activities of Coix lacryma-jobi seed and root oil potential for meningitis treatment

“…Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae, Pseudomonas aeruginosa, Klebsiella pneumoniae, Streptococcus feaecalis, and Escherichia coli are the leading causes of bacterial meningitis infections worldwide (Al-Gosha'ah et al, 2014;Paireau et al, 2016;van de Beek et al, 2016;Yezli et al, 2016). Bacterial meningitis causes inflammation of the meninges, which leads to a sudden onset of fever, headache, stiff neck, nausea, vomiting, and altered mental status, and can rapidly result in death (Paireau et al, 2016;van de Beek et al, 2016).…”

“…The first reported international outbreak of bacterial meningitis following the Hajj occurred in 1987 (van de Beek et al, 2012;Yezli et al, 2016). This epidemic emphasized the potentially high risk of transmission during the pilgrimage and in their home countries (Al-Gosha'ah et al, 2014;van de Beek et al, 2012;van de Beek et al, 2016), such as Indonesia.…”
