The chemical compositions of the leaf and seed extracts were profiled using GC-MS while Gram positive (Staphylococcus aureus and Enterococcus faecalis) and Gram negative bacteria (Klebsiella pneumoniae, Salmonella typhi, Escherichia coli and Pseudomonas aeruginosa) were used to test for antibacterial potentials. GC-MS analysis showed that the main components in the leaf extract of S. tora were cisoleic acid (29.4%), 1, E-11, Z-13-octadecatriene (13.4%), palmitic acid (13.3%), 1,E-8,Z-10-pentadecatriene (11.4%) and stearic acid (11.0%) while methyl-1-allyl-2-hydroxycyclopentanecarboxylate (20.0%), 6,9- pentadecadien-1-ol (20.0%), cis-oleic acid (16.2%), methyl-7-hexadecenoate (7.5%) and palmitic acid (6.5%) were the most abundant components in the seed extract. The leaves showed a higher inhibitory effect than the seeds, with a zone of inhibition mean value that ranged from 12.3-18.5 mm, while that of seeds ranged from 10-16.5 mm. Klebsiella pneumoniae exhibited the highest susceptibility (18.5 mm), while Salmonella typhi showed the lowest (10 mm). The results of this study revealed that the leaves and the stems of the plant contained some medicinally active phytochemicals that may be important as antimicrobial agent.","PeriodicalId":15045,"journal":{"name":"Journal of Bacteriology & Parasitology","volume":"28 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84541434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With increase in population growth, quality water needed for consumption by man is on the decline because of environmental pollution. Thus the main aim of this study was to investigate the prevalence level of E. coli O157:H7 in water bodies in Ile-Ife and its environs which are the sources of water for man’s consumption. Four hundred and fifty-one samples were investigated from five major sources of water namely; well, stream, borehole, bottled and sachet. The water samples were screened for E. coli and serologically characterized for E. coli O157:H7. The E. coli O157:H7 isolates obtained were further characterized for stx 1, stx 2 and eaeA genes. The result revealed that well water and stream water had a prevalence of 8.74% and 4.59% respectively. Antibiotic resistance profile of E. coli isolates showed that both sources harboured isolates that are resistant to three classes of antibiotics. The virulence gene distribution shows that stx 1 and stx 2 were present in all the E. coli O157:H7 investigated. In conclusion, it appears that the gastroenteritis outbreaks experienced in the study area may be due to the presence of E. coli O157:H7 in water samples.","PeriodicalId":15045,"journal":{"name":"Journal of Bacteriology & Parasitology","volume":"20 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76303476","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prevalence of S. aureus varies between age, gender, ethnicity, geographic location, and body niche. S. aureus is very well adapted to colonize the nares, throat, perineum skin and the intestine also. So the human body and skin probably provide favorite condition for this species. The aim of the study is to evaluate the prevalence of S. aureus, and also to describe observational result of the influence bacterial-host and environmental/modifiable factors might have on the relationship with humans. Method: This study was carried out from October 2016 to December 2017 across hospitalized patients from different units of Mother Theresa Hospital Center. About 258 Clinical specimens were collected based on infection type such as wound, pus/exudates, blood, urine, sputum and indwelling medical devices. We isolated and identified S. aureus using standard tests like catalase, coagulase, and growth on mannitol salt agar. Results: Over all 258 specimens tested, the prevalence of S. aureus was found in 36% patients. Out of all 93 cases isolated with S. aureus, 25% were from urine infections; 24.6 % from skin and soft-tissue infections cases; 20.4 from vaginal and urethral swab; 15% from nasal and ear swab cases and 15% from blood stream, indwelling medical devices and catheter-associated infections. We did find statistically significant differences between Infection and sex, residence area, wards and place where the samples were collected. In all cases the p value was<0.05. Conclusions: The rate of S. aureus in hospitalized patients in this study was high. These results indicated that this type of infection is a significant concern for health services and patients. The highest percentage of S. aureus found in surgical and non-surgical wounds suggests that further investigation should be implemented. A screening of all hospitalized cases can lead to reduce the incidence of this infection in the hospital environment and control the risk factors.","PeriodicalId":15045,"journal":{"name":"Journal of Bacteriology & Parasitology","volume":"13 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76023700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Active TB disease in humans is caused mainly by Mycobacterium tuberculosis. Some disease cases are also caused by Mycobacterium africanum (mainly in Africa) and Mycobacterium bovis (due to consumption of unpasteurized milk), two other species belonging to the M. tuberculosis complex [1]. The infection is mainly acquired by inhalation of tubercle bacilli expectorated by pulmonary TB patients (open TB) during close human contact [1]. Primary infection either leads to clinically active TB disease or the host immune response arrests multiplication of M. tuberculosis. However, complete sterilization is achieved in some individuals only while few bacilli in other individuals escape killing, become dormant and persist in granulomatous lesions (latent TB infection) [1]. The latent infection may remain dormant for a long time or resuscitates to cause active TB, years to decades later, often due to weakening of the host immune response [1]. Nearly 25% of the world population is latently infected with tubercle bacilli and 5%-10% of the infected individuals will eventually develop active TB disease during their life-time [2]. Reactivation of latent infection is more frequent in people with immunodeficiencies, diabetes, other immunosuppressive conditions or co-infection with human immunodeficiency virus (HIV) [1]. Active TB disease in low TB incidence/high income countries mostly occurs in foreign-born individuals due to reactivation of latent infection while recent infection/re-infection is common in TB endemic countries [1,3].","PeriodicalId":15045,"journal":{"name":"Journal of Bacteriology & Parasitology","volume":"19 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84532952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
