Microorganisms are ubiquitous, they are found everywhere. Mobile phones are not an exception. Mobile phones, also referred to as palmtops act as fomites, a source  of infection because the palms used to handle mobile phones are often times in contact with surfaces which may have been pre-infected; nevertheless, their potential role in transmission of infections is of great concern. A cross-sectional study (male and female) was done from June to August 2018 at Caritas University, Amorji-Nike, Enugu State, in order to investigate the prevalence of bacterial contamination of mobile phones of students. Swab samples were collected from 50 mobile phones of Caritas University students. These were tested for bacterial contamination in the Microbiology laboratory. Quantification of bacteria was performed using standard streak plate technique. Isolated bacteria were identified using standard microbiological methods which include: cultural and morphological characterization and biochemical test. Antimicrobial susceptibility was also done. The microorganism isolated from students’ mobile phones and their percentage frequency of occurrence were: E. coli (31.9%), S. aureus (40.4%), P. aeruginosa (8.5%), K. pneumonia (4.3%) and Streptococcus sp. (14.9%). The result showed that Staphylococcus sp. has the highest percentage of occurrence. The antibiotic sensitivity test indicated the varied resistance of isolated bacteria to antibiotics used in this study, although most isolated bacteria were sensitive to erythromycin and chloramphenicol except the isolates of E. coli which were the most resistant to the antibiotics used. The high prevalence of bacterial agents isolated from students’ mobile phones was attributed to poor hygiene and sanitary practices. It is recommended that students should wash their hands after using mobile phones, before eating or undertaking any venture requiring sepsis.

This study evaluated the prevalence of malaria in pregnant women attending antenatal clinics in Delta state. Thick-film microscopy was used to detect parasitaemia while polymerase chain reaction (PCR) was employed to confirm positivity. Statistical method used were Chi square, Paired Sample T test and Pearson Correlation test at 5% level using SPSS version 23.0. Out of three hundred and fifty (350) HIV-negative and asymptomatic pregnant women examined at first antenatal registration, one hundred and twenty-two (122) were found positive for malaria parasite. The percentage prevalence of malaria positive cases recorded using microscopy was 34.86% (122/350) while PCR confirmed the positivity of 84% (21/25) for both positive and negative samples derived from microscopy. Prevalence of malaria in relation to age, gravidity, and educational qualification were statistically significant while prevalence in relation to occupation, the hospital they attended were not statistically significant. Participants within the age group of 15-19(66.6%), primigravidae (42.6%), primary education (100%) and traders/businessmen had the highest prevalence of malaria. It is therefore recommended that malaria test should be one of the routine tests compulsorily done on pregnant women to avoid complications and public awareness campaign programs on preventive measures against malaria should be regularly conducted to make the journey to eradication of malaria from Nigeria an easier one.
