Abstract:

 Background: Sickle cell disease (SCD) is associated with chronic haemolysis, immuno-suppression and suscepti- bility to infections, which may trigger infection-associated haemolysis (IAH). SCD patients are vulnerable to anaemic effect of IAH due to vicious interaction between pre-existing ‘inherited’ chronic haemolysis and ‘acquired’ IAH. IAH in SCD manifests as febrile haemolytic crisis with clinical and laboratory features of severe anaemia or pancytopenia. Clinico-pathological perspectives of IAH in SCD are fragmented. This review presents a comprehen- sive but concise overview of pathogenesis, management and prevention of IAH in SCD.

Abstract: 

Background: The family Enterobacteriaceae belongs to the order Enterobacterales, a large diverse group of Gramnegative, facultatively anaerobic bacteria that sometimes cause multidrug-resistant infections which treatment options are often challenging. They are the leading cause of nosocomial bloodstream infection (BSI) and urinary tract infections (UTI). The objective of the study was to carry out a point-prevalence survey of antimicrobial resistance and carbapenem-resistant Enterobacteriaceae (CRE) clinical isolates in two hospitals in Kuwait and Nigeria.

Abstract:

Background: Neonatal sepsis is one of the most important causes of morbidity and mortality among neonates, particularly in developing countries. This study aimed to determine the risk factors and in vitro antibiotic susceptibility patterns of bacterial pathogens associated with neonatal sepsis in Federal Medical Centre (FMC) and Turai Umaru Yar’adua Maternal and Children Hospital (TUYMCH), Katsina, Nigeria.

Methodology: A total of 60 hospitalized neonates evaluated for neonatal sepsis at the special care baby units (SCBU) of the two healthcare facilities whose parents gave informed consent were enrolled for the study between July and December 2020. Blood samples were aseptically collected from the neonates and cultured on BacT/Alert automated platform (BioMérieux, Mercy-Etoile, France) machine. Bacteria were identified from all positive cultures and in vitro susceptibility test was performed on the isolates to determine their minimum inhibitory concentrations (MICs) to eight selected antibiotics using the Vitek-2 compact system. Data were analyzed by SPSS version 22.0.  Continue reading “In vitro antibiotic susceptibility of bacterial pathogens and risk factors associated with culture positive neonatal sepsis  in two hospitals, Katsina metropolis, Nigeria”

Abstract:

Background: Mobile phones are increasingly associated with the transmission of pathogenic microbial agents. In the clinical setting where there is usually high exposure to pathogens, these devices may serve as vehicles for the transmission/spread of pathogens. This study determined the prevalence of bacterial contamination of mobile phones of health workers and the predisposing factors, in order to ascertain the risk of transmission of pathogenic bacteria through mobile phones.

Abstract:

 Background: The emergence and high ascendancy of infections caused by extensively-drug-resistant (XDR) and pandrug-resistant (PDR) Enterobacterales isolates is a serious clinical and public health challenge. Isolation of PDR Gram-negative bacteria (GNB) in clinical setting is very rare and rarer is the infection caused by XDR GNB. Apart from restricted therapeutic options, these infections are associated with increased mortality and morbidity. Urgent studies to re-evaluate existing therapeutic options and research into new antibiotic molecules are desperately needed. The objectives of this study are to report the emergence of rarely encountered multidrug-resistant (MDR), difficult-to-threat, CRE infections in our hospital and investigate their molecular epidemiology.

Methodology: This was a retrospective observational analysis of six patients with severe infections caused by XDR and PDR Enterobacterales isolates at Mubarak AL Kabeer Teaching Hospital, Jabriya, Kuwait, over a period of one and half years. The mechanisms of resistance in these isolates were then prospectively investigated by molecular characterization and genomic studies.
