Possible viable bacteria were isolated and determined through culture based on paper point inoculation from infected root canals of 50 patients who presented for endodontic therapy at the school of Dentistry, University of Benin Teaching Hospital and Central Hospital, Benin City. Eighty-one strains of bacteria were isolated from 50 patients. The bacterial isolates were Streptococcus species, (51), Klebsiella species (17), E. coll (5), Staphylococcus aureus (3), Micrococcus species (2), Neisseria spp. (2) and Lactobacillus. The isolation of Klebsiella spp from the study is particularly interesting, constituting 21% of all the isolated bacteria. The implications of these findings in root canal infections are presented.

Ear swabs from 350 patients with chronic otitis media attending different orthorhinolaryngological clinics at different hospitals and health centres in Benin City and Ekpoma in Edo State were screened for the presence of bacterial agents of chronic otitis media. Results revealed the presence of 19 different species indicating polymicrobial infections. Species isolated comprised Staphylococcus aureus (33.6%), Pseudomonas aeruginosa (19.3%), Proteus mirabilis (17%), Alcaligenes faecalis (6.2%) and Klebsiella aerogenes (4.3%). Others included Escherichia coli (3.3%), Proteus rettgeri (2.8%), and Staphylococcus epidermidis (2.2%), Klebsiella pneumoniae, Proteus vulgaris, Acinetobacter spp, Proteus morgani, Haemophilus influenzae, Providencia spp, Streptococcus pyogenes, Streptococcus pneumoniae, Streptococcus faecalis, non-haemolytic streptococci and Diphotheroids, each accounted for less than 2% of isolates. The study also showed a higher prevalence of chronic otitis media among males (55.7%) than females (44.3%). Cases of chronic otitis media were highest among the age groups (0-5 years) with a prevalence rate of 50% and least among the 6-10 year age group with a prevalence rate of 14.9%. Antibiogram of isolates revealed marked sensitivities (over 90% of the isolates) to ciproxin, tarivid, rocephin and fortum whereas over 70% were resistant to penicillin and ampicillin. Results have indicated that Staphylococcus aureus, Pseudomonas aeruginosa and Proteus mirabilis are leading bacterial agents of otitis media and highlights the high risk involved in the use of penicillin, ampicillin, streptomycin, tetracycline, chloramphenicol, erythromycin, cloxacillin and septrin in the management of chronic otitis media in our locality.

A semi-quantitative screening for asymptomatic bacteriuria was carried out in the first trimester of 500 consecutive pregnant women in Benin City. The purpose was to provide baseline data and rational therapy for asymptomatic bacteriuria in pregnant women. Of the 500 women screened, 433 clinical specimens showed significant bacteriuria, representing an incidence of 86.6%. Of this number, 38 (7.4%) were of mixed bacterial colonies while 395 (91%) were of single bacterial colonies. Staphylococcus aureus (29.8%), Escherichia coli (29.1%) and Klebsiella pneumoniae (21.5%) were the most frequently isolated pathogens. The high incidence of asymptomatic bacteriuria in pregnancy correlated significantly (P < 0.05) with the observed high proportion of pyuria. On average, sensitivity of the pathogens was ciprofloxacin 99.7%; ceftazidime 81.6%; co-trimoxazole 79.4%; augmentin 71.4%; nalidixic acid 61.7%; nitrofurantoin 61.%; gentamycin 56.9% and ampicillin 25.4%. S. aureus was most sensitive, while Proteus mirabilis was least sensitive among the pathogens. Rational therapy of asymptomatic bacteriuria in pregnant women may prevent associated risks such as pyelonephritis and pre-eclampsia.

The prevalence of asymptomatic genital infection among pregnant women and their susceptibility to antibacterial agents was investigated to provide baseline data on common asymptomatic genital microorganisms and identify potentials for development of clinical disease among this cohort of patients. High vaginal swabs were obtained from five hundred consecutive and consenting pregnant women attending the antenatal clinic of the University of Benin Teaching Hospital (UBTH) and the Central Hospital, both in Benin City, Nigeria. A total of three hundred specimens showed significant microbial growth, giving a prevalence rate of 60% for asymptomatic genital infections. Candida albicans (65%), Staphylococcus aureus (51.8%) and Enterobacteriacae (E. coli and Klebsiella species) were predominantly isolated, followed by Trichomonas vaginalis and Neisseria gonorrhoea. Most of the bacterial isolates were susceptible to ciprofloxacin, ceftazidime, cotrimoxazole, norfloxacin and augmentin. All the isolates except Streptococcus faecalis were resistant to ampicillin. These results show a high rate of asymptomatic genital tract infections among pregnant women in Benin City, which have implications for adverse maternal and neonatal outcomes.

Microbial pathogens implicated in urinary tract infection and their antibiotic susceptibility patterns as prevalent in UTI symptomatic outpatients resident in Benin City, Nigeria was the focus of this study. One hundred (100) midstream urine samples were collected into sterile plastic universal bottles from outpatients who visited the University of Benin Teaching Hospital, Nigeria and who were tentatively diagnosed as manifesting symptoms of UTI. Patients were referred to the Medical Microbiology department by the consulting doctors. Significant bacterial counts and neutrophil (pus cells) counts were carried out on samples by standard methods. Positive samples for both counts were inoculated aseptically on sterile MacConkey agar, Cystine Lactose Electrolyte Deficient (CLED) agar and Sabouraud Dextrose agar plates and incubated appropriately. Microbial isolates were identified and antibiotic sensitivity testing was carried out on isolates by standard methods. Thirty nine (39.0%) and 61 (61.0%) samples recorded significant microbial growth and no growth respectively. Gram negative bacilli constituted 86.1% (of which enterobacteriaceae made up 49.9%) while gram positive cocci made up 13.9%. Strains of uropathogens isolated were Alcaligenes spp (19.4%), Klebsiella aerogenes (16.7%), Escherichia coli (13.9%), Staphylococcus aureus (13.9%), Candida albicans (11.1%), Proteus mirabilis (8.3%), Pseudomonas aeruginosa (5.5%), Enterobacter spp (5.5%) and Providencia spp (5.5%). Occurrence of UTI in male and female patients were 58.3% and 41.7% respectively of which UTI occurred highest in the 25-46, 15-54 and 27-54 age groups in that decreasing order. Alcaligenes spp occurred most in very old female patients. Candida albicans (the only fungal uropathogen) occurred in an 8day old male patient. Other isolates occurred in much older patients. A significantly high microscopic neutrophil count or pyuria was recorded from deposits of UTI positive patients (i.e. &lt; 5/HPF). Eighteen (representing 50.5%) and 15 (47.8%) of total microbial strains isolated were sensitive to nitrofurantoin and ceftriaxone respectively. Antibiotic susceptibility profile also showed 13(41.6%), 13(41.6%), 13(41.6%) for ciprofloxacin, cefuroxime and ofloxacin respectively suggesting moderate sensitivity of the fluoroquinolones and second/third generation cephalosporins. Gentamicin, ampicillin and augmentin recorded over 70.0% resistance level each. A total of nineteen bacterial strains made of E.coli, Enterobacter spp, Proteus mirabilis, Providencia spp, Staph. aureus and Pseudomonas aeruginosa were multi drug resistant as they resisted 3, 3, 4, 4, 5 and 8 antibiotics respectively.
