“…Based on Figures 3,4,5,6, the isolates recorded in this study have been widely reported in different environments including dumpsite [4,6,7], University environment (Cafiteria, Toilets, Laboratory and laboratory preparatory rooms) [2], health centres [9,17]. Studies have shown that Aspergillus species has the highest frequency in the ambient environment [2,6,7,17]. This corresponds with findings of this study.…”

“…The wet season (characterized by low temperature and high relative humidity) enhances sporulation and subsequent release in the dry season (that is characterized by higher temperature and low relative humidity). Authors have reported that this accounts for higher fungi density in the environment during the dry season [4,6].…”

“…Hence there is every tendency that cross contamination of pathogens may occur between vendors, their buyers and the goods itself. Studies have been widely carried out showing microbial air contaminants in diverse environments including smallholder gari processing facility [3], waste dump [4,[6][7][8][9][10], around a University campus in Nigeria [2], but information of microbial air contaminants in public places like market and highway is scanty in literature. Therefore, this study focused on seasonality in fungi-aerosol around a major market along East-West road in Bayelsa State, Nigeria…”

The distribution of bio-aerosols in diverse environments is a major concern to aero-microbiologists and environmentalists in general. The study evaluated the mycological quality of the air environment around a market along East-West road in Bayelsa State, Nigeria. Petri dish containing sterile Potatoes dextrose agar was exposed for 10 minutes around a market along East-West road in Bayelsa state at a height of 1 meter. The density and diversity of the isolates were determined following standard mycological procedures. The density of the fungi–aerosols ranged from 0.0073 - 0.0268 CFU/min-m2 and was statistical higher in dry (November, January and March) compared to wet (May, July and September) seasons, an indication of seasonal influence. A total of 11 fungi species were recorded with 5 predominant species viz Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Fusarium chlamydosporum and Penicillium species (occurring in ≥66.67% of the study months), while 6 species, Aspergillus lentulus, Aspergillus nidulans, Aspergillus terreus, Cladosporium cladosporioides, Microsporum canis and Mucor species are opportunistic occurring in ≤50% of the study months). Most fungi species are found in the soil, and are known to produce toxins and cause diseases. There is need for a concerted effort by local government authorities via its agencies to sensitize people on proper hygiene practices around markets.

Landfilling is one of the indispensable parts of solid waste management in various countries. Solid waste disposed of in landfill sites provides nutrients for the proliferation of pathogenic microbes which are aerosolized into the atmosphere due to the local meteorology and various waste disposal activities. Bioaerosols released from landfill sites can create health issues for employees and adjoining public. The present study offers an overview of the microbial diversity reported in the air samples collected from various landfill sites worldwide. This paper also discusses other aspects, including effect of meteorological conditions on the bioaerosol concentrations, sampling techniques, bioaerosol exposure and potential health impacts. Analysis of literature concluded that landfill air is dominated by microbial dust or various pathogenic microbes like Enterobacteriaceae , Staphylococcus aureus , Clostridium perfringens , Acinetobacter calcoaceticus and Aspergillus fumigatus . The bioaerosols present in the landfill environment are of respirable sizes and can penetrate deep into lower respiratory systems and trigger respiratory symptoms and chronic pulmonary diseases. Most studies reported higher bioaerosol concentrations in spring and summer as higher temperature and relative humidity provide a favourable environment for survival and multiplication of microbes. Landfill workers involved in solid waste disposal activities are at the highest risk of exposure to these bioaerosols due to their proximity to solid waste and as they practise minimum personal safety and hygiene measures during working hours. Workers are recommended to use personal protective equipment and practise hygiene to reduce the impact of occupational exposure to bioaerosols.

Malaria is a mosquito-borne infectious disease of humans and other animals caused by parasitic protozoans (a type of unicellular microorganism) of the genus Plasmodium. Commonly, the disease is transmitted via a bite from an infected female Anopheles mosquito, which introduces the organisms from its saliva into a person’s circulatory system. In the blood, the protists travel to the liver to mature and reproduce. Malaria causes symptoms that typically include fever and headache which in severe cases can progress to coma or death. The disease is widespread in tropical and subtropical regions in a broadband around the equator, including much of Sub-Saharan Africa, Asia, and the Americans Five species of Plasmodium can infect and be transmitted by humans. The vast majority of deaths are caused by Plasmodium falciparum and Plasmodium vivax, while Plasmodium ovale and Plasmodium malariae cause a generally milder form of malaria that is rarely fatal. The result showed that prevalence of typhoid fever in both male and female are 9 (%) and 21 (21%) respectively. The distribution of this result was statistically significant (p<0.05; X2=4.745). The result showed that prevalence of typhoid fever in both male and female are 6 (6%) and 4 (4%) respectively. The distribution of this result was not statistically significant (p>0.05; X2=0.105). The result showed that prevalence of the co-infection in both male and female are 3 (3%) and 2 (2%) respectively. The distribution of this result was not statistically significant (p>0.05; X2=0.205). The result showed that co-infection was negatively correlated with typhoid fever in both male (r=-0.055) and female (r=-0.074) subjects. Also co infection was negatively correlated with malaria for male subjects (r=-0.044) while it is positively correlated with the female subjects (r=0.335). Similarly typhoid fever was negatively correlated with malaria in both male (r=-0.079) and females (r=-0.105) subjects. Conclusively, the results in this study showed that the prevalence of malaria and typhoid co-infections are low which means the no association was found between malaria and typhoid fever infections within the study area. Hence one cannot actually say that malaria may predispose to typhoid fever. Also cross reacting antigens are widely distributed in the microbial world and since there will always be repeated exposures to salmonella species in endemic regions, increased efforts should be made to find a better, more rapid, sensitive and specific clinical and cultural methods.
