Epidemiological data of falciparum malaria in Ado-Odo/Ota, Southwest Ogun State, Nigeria.

In this data article, Blood and corresponding saliva samples from subjects presenting with fever and parasetaemia ≥2000 were obtained from selected hospitals in Ado-Odo/Ota, Ogun State over a period of two years and analyzed using Polymerase chain reaction-Restriction fragment Length Polymorphism (PCR/Nested PCR-RFLP) to detect genetic mutations of Plasmodium falciparum chloroquine resistance transporter (Pfcrt), Plasmodium falciparum multidrugs resistance (Pfmdr1) and non-synonymous Pkelch (pk13) mutated genes. The study confirmed the presence of resistance genes in the blood and saliva samples collected from the study site.

Value of the data

The data provides an epidemiology on falciparum malaria and resistance genes in the study site.

The data set provides researchers with a platform for enhanced studies in the production of non-invasive malaria test kit using saliva.

The data establishes the need for improvement of existing drugs/ development of new ones.

Data

This data article presented and analyzed incidence and prevalence of Plasmodium falciparum and resistance genes (Pfcrt, Pfmdr1 and Pk13) in ADO-Odo/Ota, Ogun State. It also examined the prospective of saliva to serve as a non-invasive diagnostic method for malaria diagnosis [1]. This data will encourage pragmatic monitoring and surveillance of falciparum malaria in the research area as recommended by the WHO׳s recommendation [2]. It also provides researchers with a platform for enhanced studies in the production of non-invasive malaria test kit using saliva.

Experimental design, materials and methods

Samples of blood and corresponding saliva from subjects were collected from various hospitals in Ado-Odo Local government area of Ogun State for three years. The study group for the research cut across sexes of different age groups of patients presenting with fever and parasitaemia of ≥2000 parasites/ul of blood. Ethical approval for this study was obtained from the Covenant University Biological Sciences Ethical Review Committee (CUBIOSCREC). Informed consent was obtained from all participants. Where participant was a minor, consent was obtained from participant׳s guardian. Parasite identification and infective stage was determined using microscopy study. For molecular studies, Parasite DNA from blood and saliva was extracted using a genomic DNA extraction kit. Nested PCR-RFLP using the specific primers - Pfcrt, Pfmdr1 and Pk13 gene was carried out [3], [4], [5]. Amplicons were sequenced directly by using each primer for target gene amplification. Data were analysed and presented as follows; Table 1 shows the incidence of P. falciparum infection in Ado-Odo/Ota Local government area of Ogun State, Nigeria in the year 2015. Table 2 shows the incidence of falciparum malaria in the year 2016. Table 3 shows the incidence of falciparum malaria in the year 2017. Table 4 shows the prevalence of falciparum malaria within two years. Table 5 shows the prevalence of resistance genes. Fig. 1 presents the incidence of P. falciparum malaria infection in males and females. Fig. 2 presents the resistance genes detected in blood and saliva samples. Fig. 3 presents Pfcrt gene detected in blood and exact number of corresponding saliva samples.
