Abstract:
Background: Invasive candidiasis is a major hospital acquired fungal infection in Nigeria. Despite advances in support of critically ill patients, candidaemia is still associated with high morbidity and mortality. Data on Candida bloodstream infection among paediatric patients is limited in Nigeria and this informed this study, which was undertaken to investigate the prevalence, species distribution, antifungal susceptibility pattern for blood stream infections due to Candida species in University College Hospital, Ibadan, Nigeria.

Abstract:
Background: The human immunodeficiency virus (HIV) targets the host immune system, particularly the CD4 T cells. The host resistance to opportunistic and non-opportunistic infections such as tuberculosis, fungal infections, severe bacterial infections, and several malignancies is weakened as a result of destruction of these CD4 cells by HIV. The purpose of this study was to determine the prevalence of HIV among individuals who participated in pre-employment medical screening at David Umahi Federal University Teaching Hospital Uburu, Ebonyi State, Nigeria, with the aim of connecting those who are HIV-positive to voluntary counseling and treatment programs.

Abstract:

Background: Urinary tract infections (UTIs) are among the most encountered bacterial infections of humans and affect both male and female of all age groups, resulting in high mortality, without proper management. This study aimed to assess the prevalence, aetiological agents, and factors associated with symptomatic significant bacteriuria/UTI among patients attending selected hospitals in Calabar metropolis, Nigeria.

Methodology: This was a cross-sectional study of 240 patients with suspected UTI, from whom mid-stream voided urine samples were collected for culture on Cystine Lactose Electrolyte Deficient (CLED) agar. Uropathogens growth on the culture media were characterized using conventional microbiological and biochemical tests, and confirmed with API® 20E and 20NE (BioMérieux) identification system. Data on socio-demographic, clinical symptoms and potential risk factors were obtained using structured questionnaire. Pearson Chi-square was employed to determine association between categorical variables with p<0.05 considered statistically significant.

Abstract:

 Background: Urinary tract infection (UTI) is one of the most common type of infections worldwide, and this is usually preceded by asymptomatic significant bacteriuria (ASB). The emergence of antibiotic resistance in bacteria responsible for UTI makes this entity of public challenge, which has been fueled by human immunodeficiency virus (HIV) infection. This study determined the prevalence of ASB and antimicrobial susceptibility pattern of bacteria isolated from urine samples of selected HIV-infected patients in Ilorin, Nigeria.

Abstract:

 Background: The intrinsic property of Acinetobacter baumannii to survive in harsh conditions on environmental surfaces and its ability to resist commonly used antibiotics in hospitals make this pathogen to be one of the most prevalent causes of hospital infections. The present study was aimed at determining the prevalence of A. baumannii among critically ill patients in two tertiary hospitals; Alex Ekwueme-Federal University Teaching Hospital, Abakaliki (AE-FUTHA) and Mater Misericodiae Hospital Afikpo (MMHA) in Ebonyi State, southeast Nigeria.

Abstract:  

Background: Oral candidiasis is an infection that follows colonization of oral cavity by Candida species mostly Candida albicans. About 90% of HIV-infected persons develop this disease during the course of HIV infection and could serve as early sign of HIV-related immunodeficiency. Treatment involves the use of antifungal drugs. The objectives of this study are to determine the prevalence of oral candidiasis and the susceptibility of isolated Candida species to available antifungal agents among selected HIV-infected patients in a mission hospital, southeast Nigeria.  Continue reading “Prevalence and antifungal susceptibility pattern of oral candidiasis among HIV-infected patients in a Mission Hospital, southeast Nigeria”

Abstract:

 Background: To control the spread of coronavirus disease-19 (COVID-19) caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), it is necessary to adequately identify and isolate infectious patients particularly at the work place. Real time polymerase chain reaction (RT-PCR) assay is the recommended confirmatory method for the diagnosis of SARS-CoV-2 infection. The aim of this study was to determine the prevalence of SARSCoV-2 infection in Burkina Faso and to use the initial cycle threshold (Ct) values of RT-PCR as a tool to monitor the dynamics of the viral load.

Methodology: Between September 2021 and February 2022, oropharyngeal and/or nasopharyngeal swab samples of consecutively selected COVID-19 symptomatic and apparently healthy workers from the Wahgnion mining site in the South-western Burkina Faso who consented to the study were collected according to the two weeks shift program and tested for SARS-CoV-2 using RT-PCR assay. Patients positive for the virus were followed-up weekly until tests were negative. Association of the initial RT-PCR Ct values with disease duration was assessed by adjusted linear regression approach. Two-sided p value < 0.05 was considered statistically significant.

Abstract:

Background: Human papillomaviruses (HPVs) are non-enveloped, double-stranded DNA viruses and most women in the world are probably infected with at least one type of the virus during their sexual life. Oncogenic HPVs are predominantly sexually-transmitted pathogens and several high-risk types are associated with nearly all cases of cervical cancer worldwide. In view of paucity of data on the prevalence and distribution of various high risk HPV subtypes, this study was carried out to provide evidence based local data for cervical cancer preventive programs within this region.

Methodology: This was a descriptive cross-sectional study involving 145 consenting women living in Ugbegun rural community of Edo central senatorial district, Edo State, Nigeria. Informed consent of each participant was obtained and socio-demographic information collected through interviewer-administered collection tool. Cervical swab sample was collected using the female cervical cell collection kit for HPV DNA testing. HPV DNA was detected by the Hybribio 21 HPV Geno array test kit which uses polymerase chain reaction (PCR) amplification and flow through hybridization assay. Summary statistics were presented as mean, standard deviation, median, frequency and proportions as appropriate using the Statistical Package for the Social Sciences (SPSS) version 22.0. Association of sociodemographic characteristics of the women with HPV prevalence was done using the ‘t’ test, with p value less than 0.5 considered statistical significance.

Abstract:
Background: Clinical infections caused by extended-spectrum β-lactamase (ESBL)-producing bacteria constitute great burden to healthcare delivery with these resistant pathogens contributing largely to the magnitude and spread of antimicrobial resistance globally. Hence, knowledge of the risk factors for acquisition of infection caused by ESBL-producing bacteria is crucial to instituting prompt and appropriate treatment as well as prevention and control measures. This study investigated the risk factors associated with the prevalence of ESBL-producing Gram-negative bacteria (GNB) infections among hospitalized patients in Uniosun Teaching Hospital (UTH), Osogbo, Nigeria.

Methodology: A total of 359 hospitalized patients with clinical infections from whose clinical samples we isolated non-duplicate GNB were consecutively recruited. GNB were isolated following aerobic cultures of
appropriate clinical samples and MicrobactTMGNB 24E kit was used for species identification. All isolates were screened for ESBL production by the combination disc method. Relevant clinical and demographic information
was obtained using a designed data collection form, and multivariate logistic regression analysis was used to identify associated risk factors.
