  This study was undertaken to determine if artificial fingernails could contribute or serve as vehicles for transmission of food poisoning and nosocomial pathogens. Three hundred and fifty apparently healthy individuals were used. Of this number, 150 subjects were health care workers, while 200 subjects were unprofessional food handlers. Both groups were randomly selected for this study. Their artificial fingernails were swabbed and examined microbiologically by culturing them on different media. Oral interviews were also used to assess the social and educational status of subjects. Four genera of bacteria were isolated and identified, such as Staphylococcus sp., Escherichia coli, Proteus sp. and Pseudomonas sp. Among the organism identified, Staph aureus (41.7%) was predominant and frequently occurring, followed by E. coli (7.4%). From this study, it could be deduced that artificial fingernails could serve as means for transmission of pathogens to foods and causing nosocomial infections on patients. Hence, use of artificial or overgrown fingernails should be discouraged to avoid disease epidemics.

  The objective of this study was to determine the health profile and impact assessment of waste scavengers in Port Harcourt, Nigeria. To isolate and identify the potential pathogens that degrade the waste, samples were collected from 7 dumpsites and one control site. Serial dilutions of the samples were carried out and aliquots (0.1 mL) of the diluted samples were inoculated into appropriate media. Similarly, blood, stool, urine and nasal swabs were collected from 80 waste scavengers and 20 control subjects. The blood samples were used for the determination of haematological parameters and widal test, while urine, stool and nasal swabs were used for microbiological analysis. Five genera of bacteria were isolated from the waste dumpsites, which include Staphylococcus sp., Escherichia coli, Salmonella sp., Pseudomonas aeruginosa and Bacillus sp. while the control sites showed growth of Bacillus sp., only. The culture result from waste scavengers also showed similar organisms, such as Staphylococcus aureus, E. coli and Salmonella sp. There was significant decrease in the haemoglobin levels, haematocrit and Neutrophil counts of rag pickers as compared with the control subjects (p<0.05). Mean values for waste scavenger were Hb 12.12±1.85g dL-1, HCT 36.33±16.7% and Neutrophil 33.33±14.06%, while control subjects were Hb 14.48±04 g dL-1, HCT 42.66±9.47% and Neutrophil 56.55±16.83%. The AST for waste scavengers was slightly increased, while the other LFT values were decreased compared to the control subjects. It can be inferred that waste scavengers serve as vehicles for the transmission of certain pathogens that degrade waste, thereby, constituting some public health hazards.

  The effect of hepatitis B infection on the haematological parameters of 3,465 apparently healthy pregnant women attending antenatal clinic was studied over a period of 3 years in Port Harcourt, Nigeria. Fifty-seven were HBsAg positive (test) while the remaining 3,408 were HBsAg negative (control) representing a prevalence rate of 1.6%. The mean±SD obtained for Packed Cell Volume (PCV), Haemoglobin concentration (Hb conc.), platelets, total White Blood Cell count (WBC), neutrophils, lymphocytes, eosinophils, basophils and monocytes for hepatitis B positive pregnant women (test) were 22.77±2.86%, 7.26±0.56 g dL-1, 144.23±3.60 x109 L-1, 8.08±0.89x109 L-1, 78.88±2.11%, 16.68±1.87%, 1.49±0.71%, 0.04±0.19% and 2.91±1.27% in the same order. The corresponding values for hepatitis B negative pregnant women (control) were 31.96±2.78%, 10.36±0.76 g L-1, 159.84±20.70x109 L-1, 6.73±1.47x109 L-1, 69.12±3.33%, 24.02±4.01%, 2.96±1.50%, 0.04±0.20% and 3.84±1.60%. The differences between the PCV, Hb conc, platelets, TWBC, lymphocyte, eosinophil and monocyte counts of test were statistically significant from that of the control (p<0.05). There were no significant differences in the neutrophil and basophil counts of the test and control (p>0.05). There was no significant correlation (R<0.50, p>0.01) between the haematological parameters and maternal age, trimester and gravidity in the control subjects. There was however, a strong positive correlation between gravidity and PCV (R = 0.54, p<0.0.01) and haemoglobin concentration (R = 0.61, p<0.01) in the test.
