ABSTRACT
Background: Detection and quantification of gastrointestinal parasitic infections (GIPIs) causing public health problems among poorer layers of the society are still one of the Neglected Tropical Diseases (NTDs) in developing countries. Objective: The aim of the study was to detect gastrointestinal parasites among inmates of Social Welfare Homes and Low Socioeconomic Areas in Metropolitan Port Harcourt. Methods: A cross-sectional survey was carried out for the evaluation of all the 1500 participants for GIPs among residents of social welfare homes and low socioeconomic areas in Rivers State, Nigeria for a period of one year (July 2019- June 2020). Stool samples were collected from each participant for isolation of GIPs in stool sample. Formol-ether concentration methods and Modified Ziehl-Neelson Staining techniques was used for the isolation and identification of gastrointestinal parasites. Descriptive and Chi square statistical analysis was applied. Results: Out of 1500, 1,381 (92.1%) participants showed negative report, while 119(7.9%) participants were positive for GIPs. Females account for 839 (55.9%) while males were 661 (44.1%). Positivity in males accounted for 9.8% (65/661) and the females had 6.4% (54/839). Age group with high prevalence occurred among 11-15yrs (13.5%)/340. Both variables were statistically significant (p<0.05). Seasonal distribution of GIPs was high during the wet season (p<0.05). Overall, A. lumbricoides was the most predominant gastrointestinal parasites, accounting for 35.3% of the total identified. Others were as follows; T. Trichiura 26.1%, hookworm 21.9%, C. sinensis and S. mansoni 2.5%, tapeworm 1.7%, while H. nana and H. diminuta had 0.8% each. Co-infection of A. lumbricoides + hookworm and hookworm + T. Trichiura recorded 4.2% each. Protozoa species were not identified. Risk factor of the use of toilet papers was found to be statistically significant (p<0.05) among others. Conclusion: We recommend that knowledge of epidemiology and transmission routes of C. sinensis and H. diminuta needs to be improved and effective health education on personal hygiene and mass treatment should be sustainable to control the spread of gastrointestinal parasites.
ABSTRACT
Urinary tract infection correlates with significant bacteriuria. Empiric and definitive therapy depends on the sensitivity pattern of the causative agents; so it is essential to keep abreast of changes in the causative organisms. This study was carried out to determine the causative agents of significant bacteriuria and their antibiotic sensitivity pattern. Mid stream urine specimens were collected from all patients attending the Family Medicine Clinic of the Lagos State University Teaching Hospital; Ikeja Lagos in July and August of 2005. The urine specimens were transported on ice to the Medical Microbiology and Parasitology Department of the College of Medicine; Idi-Araba. Significant bacteriuria was determined by the standard loop method. Culture was performed on MacConkey agar (oxoid) and blood agar base (Oxoid) and Isolates were identified by standard laboratory methods. Antibiotic sensitivity was by disc diffusion method. Four hundred and fifty urine specimens surveyed for bacteria were from 251 females (55.8) and 199 males (44.2) with age range 13 to 89 years. Ninety four patients (20.9) had significant bacteriuria and 14 were symptomatic; making the prevalence rate of symptomatic bacteriuria 3.1. Out of 91 patients who had been on antibiotics; a significantly higher proportion (52) had bacteriuria while only 13.4 of those who had not been on antibiotics had bacteriuria. Klebsiella and Enterobacter species were more commonly isolated than E. coli. Most of the isolates were resistant to cotrimoxazole (89); tetracycline (69.1) and amoxicillin (88.1) and amoxicillin (88.1). Sensitivity rates to the urinary antiseptics ranged from 54.2 to 55.9. Many of the bacteria were sensitive to ofloxacin (92.9)); ciprofloxacin (84.7); cefotaxime(72.9); ceftriaxone(86.4) and ceftazidime( 88.1). Sensitivity to the aminoglycosides ranged from 57.7 to 59.3
