Impact of Soil Compaction on Bulk Density and Root Biomass of Quercus petraea

The impact of soil compaction on bulk density and root biomass of Quercus petraea L. was assessed after 85 years of reclamation of post-lignite mining soil at Welzow-South, in Lusatia, Germany. Bulk density of core soils sampled from 20 to 25 cm, 100 to 105 cm, and 200 to 205 cm depths and oven-dried biomass of Q. petraea roots sampled from 0 to 30 cm and at successive depths of 20 cm, up to 210 cm depth at compacted and uncompacted sites were determined. Bulk density was significantly higher at 20 to 25 cm (1.74±0.09 g cm−3) and 100 to 105 cm (1.65±0.06 g cm−3) depths of the compacted site. Likewise, compaction induced significant greater root biomass within the 0 to 70 cm depth with higher bulk density; root biomass at this depth was 2-fold greater compared to the uncompacted site. Root biomass decreased with soil depth and showed significant relationship with depth at both sites. The result indicates that, after 85 years of reclamation, the impact of soil compaction persisted as evident in higher bulk density and greater root biomass

Prevalence of Giardia species in Cattle Faecal Matter in Selected Farms in Weija and Kpong Major Water Supply Heads to Accra, Ghana.

In developing countries including Ghana, giardiasis plays a major role in gastroenteritis in vertebrate. It poses health and socio-economic burden, and continues to be one of the causes of infant and calf mortality. Their infection continues to thrive in humans due to the zoonotic transmission of infected domesticated animals including cattle, dogs and cats, and their con­tinual presence in water bodies. The objective of this study was to establish their presence and evaluate the prevalence of Giardia sp. in cattle faecal matter in the environment in the Kpong and Weija communities. The Iron-haematoxylin staining techniques was used to analyze the faecal samples in order to identify Giardia sp. (Student t- test and Chi square were the statistical analyses) used for the studies. About five percent (5.3%) prevalence was obtained in both com­munities and this was significant (p> 0.05). The parasite was found to be most prevalent (9.4%) in calves less than 3 months old and this decreased with age of calf. It was also observed that Giardia plays an important role in the cause of diarrhoea in cattle. There is the need to educate people on the disease and its implication on the quality of water from the treatment plants. Keywords: Giardia sp, water, contamination, diarrhoea, infant mortality

A Survey of Female Genital Schistosomiasis of the Lower Reproductive Tract in the Volta Basin of Ghana

Objective: To determine the prevalence of female genital schistosomiasis in riparian communities in the Volta basin of Ghana,Design: The study was a cross-sectional study conducted among women 15-49 years in the Volta Basin. Urinary schistosomiasis prevalence wasdetermined using microscopy. A structured questionnaire was also administered to collect information on the demography, obstetric history and reproductive health experiences. Cervical punch biopsywas collected from women who consented to be screened for FGS. Descriptive statistics was used to determine frequency of occurrence, chi squared and logistic regression to identify associated variablesResults: Urinary schistosomiasis prevalence among the women was 24.8% while 10.6% of them diagnosed with FGS. More FGS diagnosed women (57.7%, p value =0.04%) were observed to report copious discharge, vaginal itch (80.8%, p=0.042) and lower abdominal pain (66.7%, p= 0.041) compared to FGS negative women. The predominant abnormalobservation of the lower genital tract made was erythematous cervix (18.8%).Conclusion: The study confirms the reproductive health symptoms associated with FGS and recommends awareness creation on FGS amongwomen in endemic communities to facilitate early treatment
