Cattle breeding, a major activity of the local population, may favor exposure of humans to bovine tuberculosis. Objectives: (i) to isolate and identify M. bovis among new cases of tuberculosis with positive culture in the Sahel (Gorom-Gorom and Dori); the Center (Ouagadougou) and the Western (Bobo-Dioulasso) regions of the country; (ii) to investigate susceptibility of isolated strains to anti-tuberculosis. Methods: (i) collection of sputum from newly TB patients with a positive smear during a prospective study carried out in 1998 in the North, Central and Western region of the country and transferred at the Mycobacteriology Laboratory, (ii) optimization of operational procedures: (iii) mycobacteria strains's isolation on 3 different media (Loweinstein Jensen (LJ), LJ without glycerine and LJ supplemented with pyruvate; (iv) identification of the tuberculosis complex according to criteria such as: bacillus growth time, colony appearance, biochemical test results, bacilli growth with pyrazinamide or thiophene carboxylate hydrazide, or D-cycloserine; (v) performing antibiograms. Results: Among the isolated strains, M. bovis represented 6.2% (2/30) in Gorom-Gorom, 0% (0/18) in Dori, 2.6% (3/109) in Ouagadougou and 2.9% (2/65) in Bobo-Dioulasso. Sixty nine percent (31/45) of strains were susceptible to the main anti-tuberculosis drugs, 13 strains presented single or combined resistance and one strain was multidrug-resistant. Conclusion: We showed that M. bovis disease is prevalent in all the studied regions but at a relatively low rate. The transhumance of from the north to the west practiced by the breeders could explain why it was found M. bovis in a similar rate as in Ouagdougou and Bobo-Dioulasso where livestock activity is less intense than in Gorom-Gorom.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82047729","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}

Nanoparticles are one of the most effective therapeutic agents. Zinc oxide nanoparticles (ZnO NPs) are well known antimicrobial agents and are regarded as nontoxic and bio-safe. The present study aims to investigate the antimicrobial effect of ZnO NPs against the bacterial strains i.e. Klebsiella pneumoniae (K. pneumoniae) and Escherichia coli (E.coli). Methodology: The antibacterial activity was performed by Kirby’s Disc diffusion assay using different concentrations (0.2, 0.4, 0.6, 0.8 and 1.0) mg/ml of ZnO NPs with and without β lactam antibiotics (Ciprofloxacin and Imipenem). The Minimum inhibitory concentration (MIC) was evaluated through the standard agar dilution method. Antioxidant potential of ZnO NPs was analyzed through αα-diphenyl-β- picrylhydrazyl (DPPH) radical scavenging activity while the Cytotoxicity of ZnO NPs was evaluated through Brine shrimp lethality assay. Results: The results revealed that the highest zone of inhibition was more in K. pneumoniae i.e. 27.2 mm as compared to E.coli i.e. 13.2 mm. The MIC value for K. pneumoniae and E.coli was 0.05 mg/ml and 0.08 mg/ml respectively. Antioxidant potential of ZnO NPs increases as the concentration of NPs was increased. However, the cytotoxicity analysis showed the non-toxic effect of ZnO NPs. Conclusion: The results indicated that ZnO NPs possess strong antimicrobial activity and can enhance the antimicrobial activity of some beta-lactam antibiotics. The present study can be helpful to formulate nano-drug conjugates as antimicrobial agents in various fields of medical and pharmaceutical research.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77524445","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, despite increased reports on the activity of phytogenic compounds against disease in poultry, there is a lack of data regarding safety and residual toxicity. This two-part study investigated the general health of broiler chickens fed Berberine, Ursolic Acid, Piceid, Honokiol and Baicalin in-feed at three different levels, and assessed the poultry tissue residue of Berberine in breast muscle, upper and lower thigh, and liver through LC/MS-MS. Methods and Findings: Phase 1 trial results demonstrated that all birds appeared normal, with all gastrointestinal histologic lesions and liver histologic lesions identified within normal limits for broiler chickens in a production environment. Phase 2 trial showed that the lowest amount of Berberine, 0.03 g/kg in-feed, resulted in tissue residues below the lower limit of detection (<2 ng/g), and the highest amount of Berberine, 0.3 g/kg in-feed, yielded detectable values, although the significance of these results is still not clear. Conclusions: In conclusion, the present study suggests that the five tested phytogenic compounds are safe for use in starter, grower and finisher feeds for broiler chickens. Further exposure and risk assessment calculations regarding appropriate residue levels are necessary to evaluate the use of Berberine as a feed ingredient for poultry.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75937086","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}

Microbiological quality determinations include microbial load counts, using enumerations of total aerobic mesophilic flora, total coliforms, yeasts & moulds and Staphylococcus aureus, before and after application of essential oil, and during fish samples preservation studies. The contamination levels of market smoked fish samples were total aerobic mesophilic flora (4.3 log10 CFU/g); total coliforms (1.42 log10 CFU/g); yeasts & moulds (2.45 log10 CFU/g) and Staphylococcus aureus (1.41 log10 CFU/g). There were no microbial loads recorded for the freshly smoked mackerel fish samples. One ml of L. multiflora essential oil added to 70 g of fish samples inhibited the growth of total aerobic mesophilic flora by 100% in 24 h, while the smoked fish samples were preserved for 3 days without repeated smoking. Conclusion: L. multiflora essential oil can serve as a bio-preservative for smoked mackerel fish instead of repeated smoking or chemical preservation.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91299920","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 simple culture system which uses glass desiccator gassed with laboratory-prepared carbon dioxide (5CG-Desiccator) was found to effectively sustain trypanosomes growth in vitro and so the technique was recommended for in vitro antitrypanosomal screening of compounds and plant extracts. This paper reports an attempt to evaluate the utility of this system for the determination of IC50, IC90 values of ethanolic extracts from some medicinal plants against Trypanosoma brucei brucei using Diminazine Aceturate (DA) as standard trypanocide. Methods findings: Parasites were grown in Eagle’s Medium in the presence of varying concentrations of each plant extract in a 96-well micro-titer plate using 5CGDesiccator culture method. IC50 and IC90 values were extrapolated from two graphical approaches. Comparative analysis of IC90 values showed that extracts from four plants (Cymbopogon spp, Moringa oleifera, Vernonia amygdalina and Allium sativum) had IC90 values less than 200 g/ml, five (Azadirachta indica, Khaya senegalensis, Carica papaya, Eucalyptus spp and Aloe vera) had values between 200 g/ml and 1000 g/ml and one (Mitracarpus scaber) had value greater than 1000 g/ml. Conclusion: The results obtained using two different approaches permitted the comparative assessment of the trypanocidal potentials of the extracts. Suggestions on practical ways to improve this technique for IC50 determination of values of synthetic and plant-derived compounds/fractions were discussed.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78225244","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}

Severe leptospirosis is associated with high morbidity and mortality rates, which poses a great threat to human health. Due to the limitation of traditional clinical and laboratory diagnosis methods, pathogens for many infectious diseases, including leptospirosis, remain unknown. Recently, unbiased next generation sequencing (NGS) sheds light on the precise and rapid diagnosis of intractable infectious diseases, which is greatly beneficial to the prompt treatment and reliable prognosis. Case presentation: A 35 year old male got a fever with rapid hepato-renal-pulmonary involvement after his travel to Hunan province, China. The manifestations initiated with a jaundice-hemorrhage clinical type, and then followed by the combination of jaundice-hemorrhage and diffuse hemorrhage (PDH) clinical types, along with liver, heart, muscle and pancreas involvement. To identify the causative agent for the disease, blood sample was collected for serologicaltests, pathogen-specific PCR detection. Meanwhile, blood and sputum samples were used to do the nextgeneration sequencing, and the Leptospira interrogans serovar Copenhageni was detected and confirmed as the pathogenic agent. Based on the precise diagnosis, our patient recovered progressively with antimicrobials and supportive care. Conclusion: NGS played a critical role in the precise diagnosis of leptospirosis infection in this case. Corticosteroids combined with antibiotics treatments based on the diagnosis and clinical signs with suspicious pulmonary hemorrhage may decelerate the disease progression. The unbiased NGS would be further used in clinics for disease diagnosis especially for the uncertain and unknown pathogens.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"72 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90357297","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}

In India, Pulmonary Tuberculosis (PTB) is the most common form of the disease; however, Extrapulmonary Tuberculosis (EPTB) comprises 10 to 20% of all TB cases. The diagnosis of EPTB cases is difficult because of paucibacillary nature and consequently is associated with low sensitivity of Zhiel- Neelson (ZN) smear and culture on Lowenstein-Jensen (LJ) media as gold standard. The present study comparatively evaluates the utility of real time quantitative PCR over nested PCR and other conventional techniques for the detection of M. tuberculosis Complex (Mtc) in clinical isolates of PTB and EPTB samples at a tertiary care centre, Shri Ram Murti Smarak Institute of Medical Sciences (SRMSIMS), Bareilly. Methods and Findings: In total, 205 both pulmonary (24) and extrapulmonary (181) specimens were processed for ZN smear, culture on LJ media, nested PCR and real time quantitative PCR using IS6110 as a gene target. Out of 205 samples, none of the sample was found to be smearpositive and only 28 (14%) samples were found to be culture positive. The nested PCR and real time quantitative PCR positivity was observed 100% in culture positive specimens. However in majority of culture negative specimens the sensitivity was 100% in both nested PCR and real time quantitative PCR assays for EPTB and PTB specimens. The specificity was better in case of real time quatitative PCR as compared to nested PCR, 45.8% and 20% in case of nested PCR for nonrespiratory and respiratory specimens respectively. The specificity was increased upto 86.1 and 100% with real time quantitative PCR for EPTB and PTB cases respectively. Conclusions: The combined analysis of nested PCR, real time quantitative PCR and other lab investigations can be very useful in the rapid diagnosis of M. tuberculosis in paucibacillary extrapulmonary tuberculosis samples in Indian scenario.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73776236","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}

This study evaluates the pattern of susceptibility of pathogens commonly responsible for urinary tract infections (UTIs) to commonly used antimicrobial agents. Midstream urine samples of 80 patients (30 males and 50 females) and 20 diarrhea samples from 10 males and 10 females, who were attending clinics in Eku, Sapele and Abraka general hospitals, Delta state, between September and October 2007 were examined. Susceptibility of the urine and diarrhea bacteria isolates to ten commonly used antibiotics were investigated. Thirty five Escherichia coli isolates were obtained from the urine samples, out of which were nine hemolytic strains (25.7%), and 10 E. coli isolates from diarrhea, out of which was one strain (10%). All the hemolytic strains exhibited a significantly high resistance to septrin, sparfloxacin, amoxicillin, streptomycin, chloramphenicol but were either moderately or highly sensitive to the augmentin and gentamycin. I conclude that the incidence of hemolytic strains in urinary tract infection was higher than that observed from diarrhea because Escherichia coli strains that cause urinary tract infection typically produce hemolysins which is an important virulent factorin pathogenesis of infection, whereas those strains that are part of the gastro intestinal micro flora may not produce hemolysins and majority of the antimicrobial agents that are commonly used to treat UTIs caused by Escherichia coli in the hospitals are no longer effective due to hemolysin production. Therefore, the development and strict management of antimicrobial policy, and surveillance for resistant organisms should be given priority in Nigeria.","PeriodicalId":8142,"journal":{"name":"Archives of Clinical Microbiology","volume":"94 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89975575","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}
