| 1 | Antimicrobial resistance of abnormal vaginal discharges microorganisms in Ouagadougou,Burkina Faso显示文摘Objective:To assess the prevalence of bacterial strains and fungal strains infecting the vaginal tract and test their sensitivity to antibiotics in women attending Saint Camille Medical Centre in Ouagadougou.Methods:From January 2008 to December 2009,a total of 2000 vaginal swabs were cultivated for bacterial and fungal identification and isolation.Furthermore,bacterial strains were tested for their susceptibility to several antibiotics used in routine in the centre. Results:The results revealed that microbial isolation and identification was attempted for 1536/2000 sample,a positivity rate of 76.80%.Candida albicans(48.76%),followed by Escherichia coli(16.67%),Streptococcus agalactiae(8-14%) and Staphylococcus aureus(7.55%) were the major agents of genital tract infections in patients.Mycoplasma hominis and Ureaplasma urealyticum combined accounted for less than 7%.Trichomonas vaginalis was identified in 1.04%coses.The antimicrobial tests revealed that the microorganisms developed resistance to several antibiotics including beta lactams.However,antibiotics such as cefamenzol,ciprofloxacin and norfloxacin were still active on these bacteria.Conclusions:The results reveal that many sexually active women are infected by one or more microbial pathogens,probably because of the lock of hygiene or the adoption of some risky behaviors,such as not using condoms or having multiple sexual partners.Efforts should be made to address these points in the country. | Simplice D Karou Florencia Djigma Tani Sagna Christelle Nadembega Moctar Zeba Aboudoulaye Kabre Kokou Anani Djeneba Ouermi Charlemagne Gnoula Virginio Pietra Salvatore Pignatelli Jacques Simpore | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，4： | 2 |

| 4 | Antimicrobial,antiplasmodial,haemolytic and antioxidant activities of crude extracts from three selected Togolese medicinal plants显示文摘Objective:To investigate the antioxidant,antimicrobial,antiplasmodial,acute toxicity and haemolytic activities of methanolic extracts of three plants.Phytochemical analysis to determine the phenolic contents was also carried out.Methods:The 2,2-diphenyl-1- picryl-hydrazyl(DPPH) free radical scavenging,NCCLS broth microdilution and Plasmodium Lactate Dehydrogenase(pLDH) assays were used to determine antioxidant,antimicrobial and antiplasmodial activities,respectively.Haemolysis assay was conducted on A+ human red blood cells and acute toxicity on male Swiss albino mice.Phenolics were quantitatively determined using spectrophotometric methods.Results:The DPPH assay yielded interesting antioxidant activities of methanolic extract of Parinari curatellifolia(P.curatellifolia) and Entada africana (E.africana)(IC50 were 0.20±0.01μg/mL and 0.47±0.01μg/mL,respectively).This activity was highly correlated with phenolic contents of extracts.The antimicrobial tests displayed minimal inhibitory concentrations(MICs) values ranging from 0.90 to 1.80 mg/mL for Serratia marcescens (5.marcescens) the most susceptible bacterial strain.MIC value was 1.20 mg/mL for susceptible fungal strains including Mucor rouxi(M.rouxi),Fusarium oxyporum(F.oxyporum) and Rhizopus nigricans(R.nigricans).pLDH assay showed moderate antiplasmodial activity of Balanites aegyptiaca(B.aegyptiaca)(IC50= 24.56±3.45μg/mL),however this extract was highly haemolytic and toxic in mice(LD50= 625±128mg/kg).Conclusions:Our results support in part the use of the selected plants in the treatment of microbial infections.In addition the plant showed interesting antioxidant activity that could be useful in the management of oxidative stress. | Simplice D Karou Tchadjobo Tchacondo Lassina Ouattara Kokou Anani Aly Savadogo Amegnona Agbonon Mossaclok Ben Attaia Comlan de Souza Mohsen Sakly Jacques Simpore | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，10： | 1 |
| 5 | Epidemiology and antibiotic resistance of bacterial meningitis in Dapaong,northern Togo显示文摘Objective:To assess the seasonality of the bacterial meningitis and the antibiotic resistance of incriminated bacteria over the last three years in the northern Togo.Methods:From January 2007 to January 2010,533 cerebrospinal fluids(CSF) samples were collected from patients suspected of meningitis in the Regional Hospital of Dapaong(northern Togo).After microscopic examination,samples were cultured for bacterial identification and antibiotic susceptibility. Results:The study included 533 patients(306 male and 227 female) aged from 1 day to 55 years [average age(13.00±2.07) years].Bacterial isolation and identification were attempted for 254/533 (47.65%) samples.The bacteria]species identified were:Neisseria meningitidis A(N.meningitidis A)(58.27%),Neisseria meningitidis W135(N,meningitidis W135)(7.09%),Streptococcus pneumoniae(S.pneumoniae)(26.77%),Haemophilus influenza B(H.influenza B)(6.30%) and Enterobacteriaceae(1.57%).The results indicated that bacterial meningitis occur from November to May with a peak in February for H.influenzae and S.pneumoniae and March for Neisseriaceae. The distribution of positive CSF with regards to the age showed that subjects between 6 and 12 years followed by subjects of 0 to 5 years were most affected with respective frequencies of 67.82%and 56.52%(P<0.001).Susceptibility tests revealed that bacteria have developed resistance to several antibiotics including aminosides(resistance rate>20%for both bacterial strains),macrolides(resistance rate>30%for H.influenzae) quinolones(resistance rate>15% for H.influenzae and N.meningitidis W135).Over three years,the prevalence of S.pneumoniae significantly increased from 8.48%to 73.33%(P<0.001),while the changes in the prevalence of H.influenzae B were not statistically significant:4.24%,vs.8.89%,(P= 0.233).Conclusions: Our results indicate that data in African countries differ depending on geographical location in relation to the African meningitis belt.This underlines the importance of epidemiological surveillance of bacterial meningitis. | Simplice D Karou Abago Balaka Mitiname Bamok Damhan Tchelougou Malki Assih Kokou Anani Kodjo Agbonoko Jacques Simpore Comlan de Souza | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，11： | 1 |
| 6 | Enteric parasites prevalence at Saint Camille Medical Centre in Ouagadougou,Burkina Faso显示文摘Objective:To assess the prevalence of parasitic infections among patients attending Saint Camille Medical Centre and to estimate co-parasitic infections rates.Methods:From January to December 2009,stool samples were collected from 11 728 persons,aged from five months to 72 years and suffering from gastroenteritis.After macroscopic description,the stools were examined by light microscopy to search for the presence of parasites.Results:From the 11 728 analyzed stools,6 154(52.47%) were infected with at least one parasite.Protozoan frequently encountered were:Giardia intestinalis(43.47%),Entamoeba histolytica/Entamoeba dispar(30.74%) and Trichomonas irUestinalis(21.72%),while Hymenolepis nana(2.25%) was the most common helminth.Co-infections occurred in 22.34%cases.Within the multi-infected samples,dual and triple infections accounted for 71.18%and 20.00%,respectively.Giardia irUestinalis for protozoan and Hymenolepis nana for helminths were the most implicated co-infections.Conclusions: This study confirms that intestinal parasites are still a public health problem in Burkina Faso.To reduce the incidence of parasitic infections,it is necessary to promote the education of people so that they practice the rules of individual and collective hygiene. | Simplice Damintoti Karou Drissa Sanou Djeneba Ouermi Salvatore Pignatelli Virginio Pietra Remy Moret Jean Baptiste Nikiema Jacques Simpore | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，5： | 1 |

| 8 | Genetic diversity of hepatitis viruses in West-African countries from 1996 to 2018显示文摘The severity of hepatic pathology and the response to treatment depend on the hepatitis virus genotype in the infected host. The objective of this review was to determine the distribution of hepatitis virus genotypes in West African countries. A systematic review of the literature in PubMed, Google Scholar and Science Direct was performed to identify 52 relevant articles reporting hepatitis A, B, C, D, E and G viruses genotypes.Hepatitis B virus(HBV) genotype E with a prevalence of 90.6%(95%CI: 0.891-0.920) found in this review, is characterized by low genetic diversity. Hepatitis C virus(HCV) genotypes 1 and 2 represented 96.4% of HCV infections in West African countries, while hepatitis delta virus, hepatitis A virus, hepatitis G virus genotypes 1 and HEV genotype 3 were reported in some studies in Ghana and Nigeria. HBV genotype E is characterized by high prevalence, low genetic diversity and wide geographical distribution. Further studies on the clinical implications of HBV genotype E and HCV genotypes 1 and 2 are needed for the development of an effective treatment against this viral hepatitis in West African countries. Surveillance of the distribution of different genotypes is also needed to reduce recombination rates and prevent the emergence of more virulent viral strains. | Maléki Assih Abdoul Karim Ouattara Birama Diarra Albert Theophane Yonli Tegwindé Rebeca Compaore Dorcas Obiri-Yeboah Florencia Wendkuuni Djigma Simplice Karou Jacques Simpore | 2018 | World Journal of Hepatology2018，10，11： | 0 |
