Aims: The present study investigated the prevalence and intensity of soil-transmitted helminth contamination in dumpsite and farmland soils in Calabar, Cross River State, Nigeria. Methodology: Soil samples were randomly collected from selected dumpsites and farmlands from July to December 2019. 200 soil samples (100 samples each from dumpsites and farmland) were collected. Soil samples were analysed using Zinc sulphate flotation technique whereas soil nematode extraction for hookworm and Strongyloides larvae was carried out using the modified Baermann technique. Results: Of the 200 soil samples examined, 131 (65.5%) were positive for ova/larvae of one or more parasites. Dumpsite soils were highly contaminated with ova/larvae of soil-transmitted helminths than farmland soils with a prevalence of 79% (n=79) and 52% (n=52) respectively (P=.02). Farmlands had the highest mean intensity (6.75±1.88) of contamination with ova/larvae of soil-transmitted helminths compared to dumpsite soils (1.68±0.14). Ascaris lumbricoides recorded the highest occurrence (35.5%) (P=.003) in soil samples examined. A. lumbricoides (40%) and Trichuris trichiura (6%) contamination was higher in dumpsite soils, while Strongyloides stercoralis larvae (34%) and hookworm (10%) contamination was higher in farmland soils. Dumpsite soils recorded the highest number of parasites (84%) in the wet season, while farmland soils recorded the highest number of parasites (92%) in the dry season (P=.11). Generally, parasitic ova/larvae were more prevalent in the dry season (91%) than in the wet season (73%) (P=.33). S. stercoralis (33%) was more prevalent in the wet season followed while A. lumbricoides (43%) recorded highest occurrence in the dry season. Conclusion: This study revealed the potential health risk of contracting soil-transmitted helminth parasites in soils around farmlands and dumpsites in Calabar, Nigeria. It is therefore important that a combination of sanitation and health education be put in place for effective control of soil-transmitted helminths.

A one-year study conducted to ascertain the prevalence and risk factors associated with helminth infection in Hangul Deer Cervus hanglu hanglu at Dachigam National Park revealed that 40.45% (89 of 220 samples) were infected with four helminth species including Heamonchus contortus, Trichuris ovis, Dictyocaulus viviparus, and Moneizia expansa.  The study signified that the infection was more prevalent during the dry season (summer and autumn) as compared to the wet season (winter and spring).  The overall prevalence of Heamonchus contortus was the highest (23.18%) followed by Trichuris ovis (8.18%), followed by Dictyocaulus viviparus (5.45%), and Moneizia expansa (3.63%).  The present study should be of importance in conserving the erstwhile state animal, listed as Critically Engendered in 2017 by IUCN.

Experimental Huts

AbstractA trial was carried out using experimental huts to determine whether mosquitoes deterred from entering a building where a person slept under a permethrin-impregnated bednet would enter neighbouring dwellings where people used untreated nets. In each of the six experimental huts a man slept under a bednet for six weeks during the dry season in The Gambia. One bednet was impregnated with permethrin, the other five nets were untreated. The design of the trial was based on a series of Latin squares, so that both men and nets were rotated between huts on different nights. At the end of the trial each man had slept under each net in each hut. Mosquitoes collected from the huts each morning were used to estimate the total number of mosquitoes which had entered each hut during the night. Fewer Anopheles gambiae Giles (sensu lato), A. pharoensis Theobald and Mansonia spp. entered a hut with an impregnated bednet than those with untreated nets. However, there was no evidence that mosquitoes deterred from entering a hut with a treated net entered neighbouring huts with untreated nets. Thus it appears unlikely that people using untreated bednets in a community where most use impregnated nets would receive more bites than if everyone had an untreated net. However, the responses of mosquitoes to permethrin-impregnated bednets were found to depend both upon their species and nutritional condition since A. rufipes Gough, banded Culex spp. and non-human bloodfed A. gambiae (sensu lato) freely entered huts with a treated net.

ABSTRACTOver a 3-year period, productivity characteristics and criteria of trypanosomiasis incidence and severity have been monitored by monthly examination of individual N'Dama cattle in villages in The Gambia. From this database, 60 lactating cows in which Trypanosoma congolense or T. vivax had been detected on blood examination (group 1) were compared with 50 cows which had not been found infected with trypanosomes during the monitoring period (group 2). The latter were selected on the basis of comparability of age and stage of lactation to those of group 1 for examining the effect of trypanosome infections on the quantity of milk extracted for human consumption, and on the growth of their sucking calves. Data from a 6- to 7-month period were examined in the analysis.The quantity of daily milk extracted during the 1st month ot intection (group 1) decreased by proportionately 0·25 in comparison to the amount extracted during the preceding month when parasites were not detected. The corresponding figure in the uninfected controls (group 2) was 0·02. The mean daily milk extracted for human consumption from uninfected cows during a 6-month period was proportionately 0·26 higher than the mean for the infected cows. Growth rates of calves sucking infected and uninfected dams were similar.These observations indicate that infection with pathogenic trypanosomes of lactating N'Dama cattle causes a reduction in milk production.In economic terms, it was estimated that the decline in milk extracted for human consumption due to trypanosome infections amounted to an average of £1 per month per cow.
