Abstract:  

Background:  The main reservoir of Enterobacterales is the human gut, which has been reported as a source of hospital acquired infection. Enterobacterales carrying the extended spectrum β-lactamase (ESBL) genes have emerged over the years as significant multidrug resistant (MDR) pathogens, that have hindered effective therapy of infections caused by them, and limited treatment to a small number of drugs such as carbapenems, leading to selection pressure and emergent resistance to carbapenems. The objective of this study was to determine the faecal carriage of ESBL-producing Enterobacterales (ESPL-PE) among children under 5 years of age at the Ladoke Akintola University of Technology Teaching Hospital, Ogbomoso, Nigeria.    Continue reading “Faecal carriage of extended spectrum β-lactamase producing Enterobacterales (ESBL-PE) in children under five years of age at a tertiary hospital in southwest Nigeria”

Abstract:
Background: Diarrhea is a worldwide problem and rotavirus is the commonest viral etiologic agent. In Nigeria, diarrhea causes more than 315,000 deaths of preschool-age children annually. In Ebonyi State, it is among the leading causes of pediatric emergency visits and one of the major causes of infant morbidity and mortality. This study was aimed at determining the prevalence and associated risk factors of acute gastroenteritis due to rotavirus infection among under-five children in Abakaliki, Ebonyi state.

This was a cross-sectional study of 275 children under 5 years of age hospitalized for acute watery diarrhea, who were consecutively recruited into the study. Stool samples were collected from each child for rotavirus antigen detection using an enzyme-linked immunosorbent assay (ELISA). Socio-demographic information of each child and selected risk factors were collected using structured questionnaire. Data analysis was done on SPSS software version 20.0, and association of demographic characteristics and risk factors with rotavirus diarrhoea was measured using Chi-square test, odds ratio (and 95% confidence interval). Significant value was set at p < 0.05. Continue reading “Prevalence and risk factors of acute gastroenteritis caused by Rotavirus among children in tertiary hospitals, southeastern Nigeria”

Abstract:

Background: Intestinal helminth infection is associated with altered immune responses and compromised vaccine efficacy in infected children. Altered immune response due to Ascaris lumbricoides infection may compromise efficacy of oral poliovirus vaccination in children. There is no information on humoral immune response during oral poliovirus (OP) vaccination of A. lumbricoides–infected Nigerian children. The objective of this study is to determine the serum levels of cytokines (tumour necrosis factor–alpha TNF-α, interferongamma IFN–γ, interleukins -4, -6, -8, -10) and poliovirus-specific IgA (PV-IgA) antibody in children infected with A. lumbricoides compared with helminth-negative children (control) before and after oral poliovirus vaccination.

Abstract:

Enteroviruses and Parechoviruses are increasingly recognized as the cause of aseptic meningitis, especially in the paediatric age group. However, because of indistinguishable clinical features with bacterial meningitis, many clinicians cannot make a clear distinction in disease presentation, and a large number of cases go undiagnosed. Although polymerase chain reaction is the current standard diagnostic approach, it takes many hours or days to get a result and these tests are not available at primary and secondary levels of care in many resource-poor countries. Furthermore, diagnosis is often difficult in children due to nonspecific cellular and biochemical cerebrospinal fluid findings. Some affected children may develop neurologic or/and systemic complications, resulting in prolonged hospital admission, increasing the risk of avoidable deaths, and healthcare expenditures. This review focuses on epidemiology, presentation, and diagnosis of Enterovirus and Parechovirus meningitis, highlighting the challenges in diagnosis and the potential roles of on-site CSF virology tests in improving the quality of paediatric patient’s care. The information provided should help early case detection, thereby ensuring avoidance of unnecessary antibiotics, minimal complications, a short period of hospital stays, and a reduction in healthcare-associated costs.

Abstract:

Background: Clindamycin has been a good alternative drug to penicillins in the treatment of infections caused by Staphylococcus aureus but resistance to this agent has led to therapeutic failure. Inducible clindamycin resistance in staphylococci carrying erm genes may not be detectable by routine disk diffusion test. The objective of this study is to phenotypically detect clindamycin resistance in clinical S. aureus isolates and determine the prevalence of ermA, ermB and ermC carriage among these isolates.
Methodology: A total of 230 non-duplicate S. aureus were isolated from children admitted to Mansoura University Children Hospital during the period January 2016 and June 2017 by conventional microbiology method. Invitro antibiotic susceptibility to selected antibiotics including erythromycin was performed by the disk diffusion technique. The „D-zone‟ test was used to phenotypically detect inducible clindamycin resistance. The presence of ermA, ermB and ermC genes was confirmed by multiplex polymerase chain reaction (m-PCR) assay. Results: One hundred and seven (46.6%) isolates were phenotypically resistant to erythromycin while 109 (47.3%) were methicillin (cefoxitin) resistant S. aureus (MRSA). The macrolide-lincosamin-streptograminB (MLSB) phenotypes among the erythromycin resistant isolates were 47 (44%) inducible MLSB and 46 (43%) constitutive MLSB, while 14 (13.0%) were MS phenotype. Although, the MLSB phenotype was more predominant in MRSA (n=60, 56.1%) than MSSA (n=33, 30.7%) while the MS phenotype was more predominant in MSSA (n=9, 8.4%) than MRSA (n=5, 4.6%) isolates, the difference was not statistically significant (p=0.0777). The ermA (29.0%, n=31) and ermC (18.7%, n=20) were the most prevalent genes carried by the isolates while ermB was carried by a few (4.7%, n=5). Forty six (43%) isolates did not carry any detectable erm gene.
Conclusion: In this study, both inducible and constitutive clindamycin resistance phenotypes were common among S. aureus isolates. Although the genetic basis for this may be attributed to carriage of ermA, ermB and ermC genes, a number of the resistant isolates did not carry any of these genes.

Contexte: La clindamycine était un bon médicament alternatif aux pénicillines dans le traitement des infections causées par Staphylococcus aureus, mais la résistance à cet agent a entraîné un échec thérapeutique. La résistance inductible à la clindamycine chez les staphylocoques porteurs du gène erm peut ne pas être détectable par le test de diffusion systématique sur disque. L’objectif de cette étude est de détecter phénotypiquement la résistance à la clindamycine dans les isolats cliniques de S. aureus et de déterminer la prévalence du portage d’ermA, d’ermB et d’ermC parmi ces isolats. sélection d‟antibiotiques, notamment à l‟érythromycine, a été réalisée par la technique de diffusion sur disque. Le test de la «zone D» a été utilisé pour détecter phénotypiquement la résistance inductible à la clindamycine. La présence des gènes ermA, ermB et ermC a été confirmée par un test de réaction en chaîne de la polymérase multiplexe (m-PCR).
Résultats: Cent sept isolats (46,6%) étaient phénotypiquement résistants à l’érythromycine, tandis que 109 (47,3%) étaient résistants à la méthicilline (céfoxitine) S. aureus (MRSA). Les phénotypes macrolide-lincosamin-streptogramine B (MLSB) parmi les isolats résistants à l’érythromycine étaient 47 (44%) MLSB inductibles et 46 (43%) MLSB constitutifs, alors que 14 (13,0%) étaient des phénotypes MS. Bien que le phénotype MLSB soit plus prédominant dans le SARM (n=60, 56,1%) que le MSSA (n=33, 30,7%), le phénotype MS était plus prédominant dans le MSSA (n=9, 8,4%) que le SARM (n=5, 4,6%), la différence n’était pas statistiquement significative (p=0,0777). ErmA (29,0%, n=31) et ermC (18,7%, n=20) étaient les gènes les plus prévalents portés par les isolats, tandis que ermB était porté par quelques-uns (4,7%, n=5). Quarante-six (43%) isolats ne portaient aucun erm gène détectable.
Conclusion: Dans cette étude, les phénotypes de résistance à la clindamycine tant inductibles que constitutifs étaient courants parmi les isolats de S. aureus. Bien que la base génétique de ceci puisse être attribuée au portage des gènes ermA, ermB et ermC, un certain nombre des isolats résistants ne portaient aucun de ces gènes.
