Nigeria has both the highest case and mortality rate of malaria infection. This study examined the prevalence and intensity of malaria among transhuman pastoralists along the Gurin- Cameroun international border, Fufore Local Government Area, Adamawa State after major ITN distribution in the study area. Five nomadic settlements: Jaringel; Wuro-nelbi Waziri, Wuro-nelbi Marafa, Wuro-Kosau and Mbodere were assessed using thin film slides blood samples for the presence of malaria parasites. The total malaria prevalence in the sample areas was 24.23%. The study showed that Wuro-Kosau had the highest malaria prevalence of 35%, and the lowest prevalence was found in Wuro-nelbi Marafa which had a 20% malaria prevalence. Also, the highest malaria prevalence of 57% was recorded in the children within the age distribution of (1-10) years, while the lowest prevalence of 5.4% was observed in the 41-50 age distribution. The study also established a link (x2 = 4.471, p = 0.023) between malaria prevalence and gender in the study population. The higher malaria prevalence occurred mostly in males (62.4%) compared to females (37.6%). Malaria intensity was also higher among males (52.7%) compared to females (46.3%) (x2 = 20.78, p = 0.011). This called for a proactive measure to ensure a malaria-free society. There is a need to intensify ITN campaign and the importance of using ITNs. Proper monitoring of the use of ITNs should be put in place.","PeriodicalId":19206,"journal":{"name":"Nigerian Journal of Parasitology","volume":"133 43","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140369521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, used clothes are commonly sold as they are cheaper compared to new ones. Research was carried out to investigate the presence of pathogenic microbes such as bacteria, fungi, and protozoa in used clothes bought at Eke Awka Market in Anambra State, Nigeria. A variety of clothing items, including trousers, shirts, caps, bras, panties, baby clothes, towels, socks, head ties, and bed sheets were purchased and analysed for the presence of contaminating microbes. Techniques such as culture and plate count methods were used for the isolation of these microorganisms, and further identification was done through morphological and biochemical methods. Additionally, protozoa were specifically isolated through a washing method, which involved centrifuging the samples at 500g for 10 minutes and then observing the sediments under a microscope. The study found microorganisms such as Staphylococcus aureus, Pseudomonas aeruginosa, Aspergillus spp, Rhodoborula spp, Candida glabrata and Entamoeba coli on the clothes examined. The highest number of bacteria isolates (2.00±0.000) were from caps and socks while the least (1.00±0.000) were from bras and bed sheets. The highest number of fungi isolates (2.50±0.707) were from trousers, bras, and baby cloths while shirts, socks, and bed sheets had the least number of fungi isolates (1.00±0.000). The only protozoan isolate was found in socks. In terms of colonies formed per unit, panties had the most colony-forming units (132.5±10.607) for fungi and (63.5±4.95) for bacteria organisms while caps had the least (16±1.414) for fungi and (8.5±2.121) for bacteria organisms, respectively. It is important to note that used clothes can act as a bearer of harmful bacteria for the epidermis and other diseases and should, whenever possible, be washed and sanitized thoroughly before use.","PeriodicalId":19206,"journal":{"name":"Nigerian Journal of Parasitology","volume":"9 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140371994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five treatment levels were applied (0.002mg/ml, 0.02mg/ml, 0.2mg/ml, 2.0mg/ml and 0.0mg/ml). Trypanosome was inactive at all treatment levels of lemongrass. PCV was statistically the same at all exposure times whereas the control mice had significantly lower PCV than all treated mice apart from the control, all other treatments gave similar PCV results, but the highest grand mean value (51.87%) was obtained at 0.02mg/ml while week 4 recorded the highest value (51.53%). All treatment levels had equal effects on the mice’s rectal temperature, but exposure time had significant effects on the temperature parameter where the grand mean temperature readings significantly varied from 35.55oC in week 2 to 37.47oC in week 5. The weight of mice varied significantly with both treatment (F=16.01, p<0.05) and time (F=5.10, p<0.05) factors. The highest mean weight recorded was 38.37±2.46g at 2.0mg/ml treatment in week 5 thus, the weight of mice increased as lemon grass treatment concentration and exposure time increased. Treatment concentrations significantly affected mice PCV and weight where the control level had the lowest values for these physical parameters. Also, exposure time significantly affected both the temperature and weight of mice. A general fluctuation but decline in feed intake was observed in mice at different treatment levels of methanolic extracts of lemon grass from weeks 1-7. A strong positive significant correlation exists between PCV and feed intake (r= -0.930, p<0.05) as well as between rectal temperature and weight of mice (r= -0.948, p<0.05). PCV and weight had a strong positive correlation though insignificant (r= 0.728, p>0.05).

The objective of this study was to determine the frequency of HBV and malaria co-infections during LGA among expectant mothers. This study used a cross-sectional, prospective design. Blood samples were collected from both pregnant and non-pregnant women for parasitological and serological examinations in the study area. This was performed to compare the severity of infections between pregnant and non- pregnant women, as pregnant women are more susceptible to infections. The study included 50 women who attended antenatal care at the time of this project and 10 non-pregnant women who came to the hospitals for check-ups. Samples of people aged 18 to 52 years were collected. Age groups of 18-28 and 40-50 years had the greatest 30(50%) and lowest 8(13%) populations of women screened for malaria and hepatitis B co-infection, respectively. The 1st and 3rd trimesters were followed by the 2nd trimester, which had the highest prevalence. Only the second trimester had a 2% prevalence rate of hepatitis B. Farmers were the group most likely to contract malaria (92%). The percentage of government employees who had malaria and hepatitis B was the highest 20%), followed by traders (5%). Ogrute, the seat of the Local Government had a high rate of malaria infection despite having several medical facilities and less farming activities. Olido (25%), followed by Ogrute (14 point 3%), had the highest rate of co-infection with hepatitis B and malaria. The PCV ranges of 25–27(100%) and 28–30(100%) had the highest prevalence of malaria.

In this study, 18S rDNA gene was employed for the molecular characterization of morphologically identified Radix natalensis collected from Nigerian Northern cities of Gombe and Jos. The obtained result revealed that the amplification of the 18S rDNA gene at 450bp identified and confirmed the collected species as Radix natalensis. BLASTn search showed that sequences of Nigerian isolates of Radix natalensis had high (99-00%) degree of similarities with each other and with other sequence deposits in the NCBI GenBank. The Nigerian sequences on phylogenetic analysis formed a separate clade distinct from other sequences of Radix natalensis from other parts of Africa and the rest of the world, suggestive of clustering based on geographical location. Thus, the availability and confirmation of Radix (Lymnaea) natalensis from the study locations as evidenced by the results of this study further justifies the assertion of Lymnaea natalensis, being a putative intermediate host of Fasciola spp. in Nigeria.","PeriodicalId":19206,"journal":{"name":"Nigerian Journal of Parasitology","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140372406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Parasite infection is a common problem in organic pig production, which can threaten the food safety of pork products, and cause economic losses to organic farmers. Hence assessing various channels by which these diseases can be transmitted is very important. This study was carried out to ascertain the distribution of intestinal parasites in slurries from a piggery in Enugu, South East Nigeria. In this study, a total of 100 pooled samples were examined from 5 farms. These samples were analyzed using the formol ether concentration technique. Out of 100 pooled samples examined, 67% of the samples were positive for intestinal parasites. The occurrence rate of the different parasites encountered was: Ascaris suum (11.9%), Trichuris suis (10.4%), Taenia solium (7.6%), Strongyloides ransomi (3.0%), Schistosoma sp.(3.0%), Entamoeba suis (28.6%), Entamoeba polecki (1.5%) and Ancylostoma duodenale (20.9%). This study is of utmost importance as findings from this study highlight the presence of various intestinal parasites in effluent slurries. There are prospects of the spread of these slurries from piggeries into the surrounding environment (which includes residential areas, commercial areas and even farmlands). Deworming of pigs to reduce parasite load is highly advocated.","PeriodicalId":19206,"journal":{"name":"Nigerian Journal of Parasitology","volume":"9 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140373293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stool samples were collected from 495 randomly selected pupils and examined using the direct smear technique to determine the prevalence of helminthic infections with predictor variables being regressed against outcome variables. A structured questionnaire was used to obtain biodata from the pupils to assess the association of intestinal helminths with socio-economic variables. The overall percentage of intestinal helminth-infected pupils had no statistical significance (p=0.1294). The probability of the outcome variable occurring rose by approximately 1.18 and 1.15 times for every unit higher in the predictor variable, as indicated by the positive coefficients for S1 and S4 schools (0.164821 and 0.136310). Only Trichuris infection exhibited a negative coefficient (-2.535188) among single infections and was significantly associated (p=0.0249). Ascaris + hookworm and Ascaris + Trichuris infections among the multiple infections revealed negative and positive coefficients (- 9.730077 and 1731.696, respectively), and they were strongly related (p=0.0001 and 0.0000). The number of infected students in (14-18) age range had a positive coefficient (0.020680) and was significantly (p=0.0441) associated with odds ratios of about 1.02, meaning that the odds of the dependent variables increase by about 1.02 times for every unit increase in the independent variable. The proportion of males with the infection displayed positive coefficients (0.980800) and was significantly (p=0.0052) associated with odds ratios of about 2.67, indicating that the likelihood of outcome variables occurring increases by approximately 2.67 times for every unit rise in the predictor variable. Conclusively, the findings observed could be attributed to the poor socio-economic status and poor personal hygiene arising from the lack of basic amenities such as pipe-borne water and other sanitary facilities in the study location. Adequate health education on sanitation, provision of portable drinking water, toilet facilities and mass deworming programmes are highly recommended in the area.","PeriodicalId":19206,"journal":{"name":"Nigerian Journal of Parasitology","volume":"18 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140369149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
