Aim: This study was aimed to determine the virulent genes and antibiotic resistance patterns among circulating diarrheagenic Escherichia coli (DEC) pathotypes in a tertiary care health center east of Nigeria. Materials Methods: Diarrheal stool samples were obtained from 80 children under 5 years E. isolated identified using standard biochemical molecular methods. Multiplex polymerase chain reaction (PCR) used detect eight DEC. Disk diffusion method susceptibility Results: DEC infection...

Introduction: The most common oral hygiene aid used to improve the health of an individual is toothbrush. Hence, it could play a role in initiation and transmission infections diseases. This study aimed at investigating presence haemolytic bacteria on toothbrushes. Methods: A close-ended questionnaire was designed distributed hundred Nigerian students. employed ascertain attitudes students towards their Twenty samples already-used toothbrush (1-3 months) were randomly collected from heads...

Aeromonas dhakensis is the most virulent species pathogenic to both animals and humans. The degree of its risk health seems masked by misidentifications. We present genome sequence A. Igbk (sequence type 1171), associated with snails, harboring OXA-726 gene in chromosome.

Background. Diarrheagenic E. coli (DEC) is an etiological agent of childhood diarrhea. Resistance against commonly used drugs in the empirical treatment enteric infections has increased among DEC. Relationship between antibiotic resistance and biofilm formation microorganisms have been widely reported. This study was aimed to determine production pattern DEC pathotypes isolated from stools children aged 0–5 years with acute diarrheal disease Abakaliki, Nigeria. Materials methods. Diarrheal...

It has been suggested that coagulase-negative staphylococci can serve as reservoirs of virulence genes for other bacteria. This study assessed the presence such in selected isolates recovered from meat giant African snail (Achatina achatina).Virulence were detected using a polymerase chain reaction targeting specific primers. Two representative identified 16S rRNA gene sequencing.The results showed staphylococcal enterotoxin A (sea) was present five out eight studied. The expressed...

We describe the draft genome sequence and annotation of Citrobacter cronae strain Awk (sequence type 880), recovered from fresh edible snails ( Achatina achatina ) commercially available in Awka Metropolis, Nigeria. The contains 4,629 protein-coding genes, 107 RNA-coding several antimicrobial resistance including bla CMY-98 qnrB12 .

DOI: 10.20286/ajlsr-040295 Leaf extracts of Moringa oleifera (aqueous, diethyl ether, ethanol, and ethyl acetate) were tested on Echerichia coli, Pseudomonas aeroginosa, Staphylococcus aureus, Salmonella typhi, Streptococcus pyogenes klebsiella aerogenes using agar well diffusion method. Antibiotics (Control) used tetracycline ciprofloxacin at 250mg/ml. Results obtained showed that 200mg/ml acetate 100% aqueous had more effect than 160mg/ml 80% respectively. The results typhi was susceptible...
