This study was conducted in Biological sciences laboratory Al-qalam University Katsina between the months of November 2021 to January 2022. Eighteen different types of oral liquid drugs (9 syrups and 9 suspensions) manufactured in different pharmaceutical industries of Nigeria were microbiologically examined using standard cultural and biochemical methods. All the samples were found to be contaminated with total viable bacteria and fungi with a maximum load of 103 cfu/ml among all samples were exceeded the United States Pharmacopeia (USP) limit (<102 cfu/ml). While the presences bacteria including; E.coli, Salmonella spp., Shigella spp., were found to be presences in almost all samples, (the former of E.coli in 11 syrups and suspension samples, the Salmonella spp. in 3 suspension samples and the Shigella spp. In 8 suspensions). Existence of microorganisms in the oral liquid samples might explain the treatment complicacy of the diseased children. A routine microbiological study of such drugs is thus suggested.","PeriodicalId":257510,"journal":{"name":"Open Access Journal of Microbiology & Biotechnology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134251305","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 cancer evolves over a longer period of time and can be screened by different laboratory tests. In developed countries although the rate of incidence and mortality has been reduced, in developing countries the incidence rate still remains high. A large number of factors have been reported that promote the risk of cervical cancer. Some host factors play crucial role in the induction of the malignant transformation. These include micro RNAs that have known to act as oncogenes or tumor suppressor genes in tumors of cervical cancer. Certain high throughput technologies have generated data on miRNAs that are significant in the pathogenesis of cervical cancer. The data has been investigated extensively with the help of tools of bioinformatics for identification of potential biomarkers of cervical cancer. In the current article, we aim to discuss the properties of the tools of bioinformatics that have paved the research on cervical cancer. It is concluded that there is a need of development of large number and various types of tools of bioinformatics facilitating identification of potential biomarkers of cervical cancer for early diagnosis and better treatment regimen.","PeriodicalId":257510,"journal":{"name":"Open Access Journal of Microbiology & Biotechnology","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121814743","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}

However, during processing contaminants from raw materials, equipment or food handlers could be easily transferred to the final product of fruit juices resulting in food borne illnesses. This community-based study was conducted in Wolaita sodo town using both laboratory experiments and questionnaire. The aim of the study was to assess the bacteriological quality and safety of locally prepared unpasteurized fruit juices from fruit juice houses in Wolaita sodo town. The questionnaire was used to assess source of fruit, way of processing and handling of fruit juices. The total viable bacterial count of avocado and mango ranged between 2.05x105 - 5x105 cfu/ml and 1x105 - 3x105 cfu/ ml, respectively. The total Staphylococcus counts from avocado and mango were between 2 x105 - 4x105 cfu/ml and 2.1x105 - 2.75x105 cfu/ml, respectively. The total coliform counts of avocado and mango were found to be 1.15x105 - 3.25x105 and 1x105 - 3 x105 cfu/ml, respectively. From a total of 72 samples, 13.8%, of the avocado and 5.55% of the mango samples were detected positive for Staphylococcus aureus whereas Escherichia coli were found in 11% of avocado and 5.55% of mango samples. None of the mango samples were positive for Streptococcus spp and Shigella spp while these species were detected in avocado with 2.77% and 5.55%, respectively. The chemical treatment using 0.1% sodium benzoate was the most effective in reducing total viable bacterial count followed by lemon squeeze. All of the pathogenic bacteria were found to be resistant to penicillin and ampicillin, and almost all were sensitive to erythromycin and ceftriaxone. Most venders obtained fruits from the open market and most juice makers lacked training in food hygiene and safety.","PeriodicalId":257510,"journal":{"name":"Open Access Journal of Microbiology & Biotechnology","volume":"14 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132580595","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}

A number of microorganisms have been shown to produce and accumulate SCO. In the present study a methodical attempt was made to isolate potential SCO producers from Indian water sources. Saltwater samples from the Arabian Sea and freshwater samples from an Indian cold-water river (Pindhari River, Uttarakhand) were collected and studied for the occurrence of lipid producing microbes. Of the several isolates shortlisted as lipid producers three isolates from this study were identified as potential SCO producers based on their lipid producing abilities. The types of fatty acids comprising the SCO from selected isolates were studied by Gas Chromatography (GC) and confirmed by Gas Chromatography/Mass Spectrometry (GC/MS). Lipid profiles from the GC analysis showed that the isolates in this study produced economically and nutritionally valuable Monounsaturated fatty acids (MUFA) like Palmitoleic acid and Oleic acid. Also, two isolates from the Arabian Sea were seen to produce a valuable omega-3 Polyunsaturated Fatty Acid (PUFA) like Eicosapentanoic acid. While a freshwater isolate produced Linoleic acid an omega-6 PUFA. Selected isolates were characterized for their biochemical characteristics and identified molecularly by 16S rRNA sequencing. Ornithinibacillus sp. Marseille-P3601 strain isolated in our study from the cold-water River Pindhari, Uttarakhand is found capable of producing PUFA.","PeriodicalId":257510,"journal":{"name":"Open Access Journal of Microbiology & Biotechnology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130777181","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}
