Prospective Study of Intestinal Parasites in Children Hospitalized in the Pediatric Department at the Hospital in El Eldrissi (Kenitra City - Morocco)

The aim of this study is to determine the epidemiology and prevalence of intestinal parasites in children hospitalized in the pediatric ward at the hospital El Eldrissi Kenitra during the period 2011 from the month February to May. During the study period a prevalence of 49% was recorded among the whole sample studied. The male is the most parasitized with 63%. The mean age was 6.5 ± 0.39 year. Child aged 4 to 10 years are most affected with a frequency of 57%. The majority of parasitised patients were from rural areas (64%). The results of the parasitological analysis showed predominance of protozoa (90.6%) compared with Helminths (9.4%)

Description of waters pollution by crude O il at Ajdabiya, Libya

Water pollution comes from several industrial, agricultural and urban sources. Among these pollutants, petrochemicals waste, are dumped without treatment in the sea, lakes and ground in Libya. In our present work, the objective is to study the impact of waste from crude oil extraction on the environment of the Libyan region of Ajdabiya during the period 2013. The physico-chemical parameters are: Temperature (°C), pH, electrical conductivity (CE), TDS, CL-, NO3-, SO4--, HCO3-, Na+, Mg++, K+, Ca++, Salinity, Total Hardness (TH). The heavy metals followed are radium, lead, bismuth, actinium, thallium, uranium, iron (acidified and unacidified), fluoride, barium and strontium.The mineralization faithfully follows the rates of dissolved salts. The electrical conductivity varies from 7880 to 46700 μs/cm and far exceeds the Libyan irrigation standards (>2700μs/cm). Concerning the nitrate their contents range from 230 to 1210 mg/L and clearly reflect the crude oil pollution origin. Radioactive elements are present and need particular attentionThe Piper diagram and Wilcox-Riversade projections shows that the waters associated with crude oil have a chloride-sodium and potassium or sulphated sodic and slightly bicarbonated sodium or potassium facies. Moreover, the hydrophysicochemical plot shows that the quality of the water associated with the oil of Ajdabiya-Jalo Libya is poor and above all a degraded quality

GIS and Statistical Evaluation of Fluoride Content in Southern Part of Upper Rasyan Aquifer, Taiz, Yemen

Fluorosis continues to be an endemic problem in Yemen. More areas are being affected by fluorosis in different parts of this country. The present study aims to identify the intensity and the spatial extent of fluoride concentration in groundwater of the southern part of the upper Wadi Rasyan, Taiz, Yemen. 93 sampling points were selected; the sampling included all types of sources of groundwater and all types of aquifers. The results show that 71% of samples exceed the WHO drinking water guidelines value of 1.5 mg/l, and there are wide variation for groundwater’s content of fluoride in the same aquifer (whether, volcanic and alluvial) and in the same of groundwater type, and these variations between the different water types or between the different depths of water (alluvial and volcanic aquifers) are not significantly different. The high concentration of fluoride in groundwater of the volcanic aquifer is likely because of the nature of geology formations by the water-rock interaction result of long-time residence of water in contact with the geology formation. The high concentration of fluoride in the alluvial aquifer likely resulting the waste of urban and industrial activates sources, the over exploration of groundwater, the arid climatic and the activities agriculture

DESCRIPTION DES HABITUDES ALIMENTAIRES DU CHINCHARD TRACHURUS TRACHURUS DE L’ATLANTIQUE NORD MAROCAIN

The study relates to the description of the diet of horse mackerel “Trachurus trachurus” of the northern Moroccan Atlantic ocean. The fishes were captured in July 2010 between Larache and Sidi Ifni. The 120 individuals sampled were between 15 and 41cm and weighed between 30 and 484g. The nutritional composition shows that the Trachurus trachurus is a carnivore species. Four major taxonomic groups of prey have been identified (crustaceans, mollusks, echinoderms and fish) .The diet varies with the size of individuals who tend to ingest prey to larger and larger as their size increases. The emptiness coefficient is within 27.5%. The proportion of empty stomachs varied by size classes

Geographic Distribution of the Anopheles labranchiae Species Malaria Vector in the Province of Sidi Slimane, Morocco

The mosquitoes Culicidae have a medical and veterinary interest as they play an important role in the transmission of many parasitic and / or viral diseases and are a source of nuisance to humans. The province of Sidi Slimane remains exposed to the risk of emergence and recurrence of new cases of malaria due to the existence of breeding sites constituting a favorable biotope for the development and evolution of Culicidea, vectors of diseases. In the context of geographical distribution study of the Anopheles labranchiae specie in the province of Sidi Slimane during the period 2015- 2017, twenty larval breeding sites were monitored and surveyed in time and space. We have mapped the positive larval breeding sites of Anopheles labranchiae, the main vector of malaria transmission in Morocco, and identified the localities at risk in order to facilitate the fighting operations and to maintain the epidemiological situation at zero cases of indigenous malaria in the zone of study

Trematode infection among freshwater gastropods in the Gharb area, Morocco

In the summer of 2012 and the spring of 2013, a snail survey aimed at determining relationships between the distribution of molluscan fauna, various environmental factors and trematode infection was carried out in the Gharb area, Morocco. The molluscan fauna consisted of eleven species belonging to 6 families, (including 9 gastropods and 2 bivalves). Cercariae belonging to five families were collected. Only Melanopsis praemorsa, Lymnea peregra and Lymnaea truncatula issued the cercariae. No case of mixed-species infections was found. The present study, first of its kind at the Gharb region, paved the way for other studies to know information about the distribution and ecology of freshwater molluscs in the region. Keywords : Cercariae, freshwater gastropods, Trematode infection, The Garb area, Morocco.

Profil Epidemiologique De La Leishmaniose Cutanee Dans La Region Du Gharb- Maroc De 2006 À 2014

Between 2006 and 2014, 439 cases of cutaneous leishmaniasis were recorded in the region of Gharb Chrarda Beni Hssen in the north-west of Morocco. With an annual incidence of 49.1 cases per year and a sex-ratio (M / F) of 0.71. The disease has affected all age groups. The most stricken population is children and young people between the ages of 6 months and 30 years with more than 60.26 % of cases. Therefore, Cutaneous leishmaniasis almost hits the rural and urban areas but with an uneven impact. It is higher in rural areas where they are registered with a percentage of 56.7% of cases in contrast to a percentage of 43.3% in urban areas

Leishmaniose Cutanées À Ain Dfali, Aspects Épidémio-Cliniques Comparatifs De 132 Cas

Since the end of the 19th century, cutaneous leishmaniasis (CL) has been regarded as a public health problem in our country, Morocco. The aim of this study is to describe the clinical and epidemiological profile and posttherapeutic evolution of patients with cutaneous leishmaniasis in the Ain Dfali’s health center. We carried out a study based on the use of records and the observation of patients with cutaneous leishmaniasis between January 2006 and December 2015. Also, we collected 132 cases of cutaneous leishmaniasis. The mean age of patients was 19.8 years with extremes from 6 months to 61 years. The sex ratio was 0.76 M / F. The mean duration of lesions was 1.6 months with extremes of 2 weeks to 10 months. Fall preponderance was noted (41.6%). The most frequent clinical appearance was that of a single ulcero-pulmonary nodule (61%) (71.9%) and was seated on the face (57.5%). The diagnosis was mentioned clinically and confirmed by direct parasitological examination. Glucantime® was the treatment of choice that was used intralesionally. The post-therapeutic evolution was favourable with almost a complete disappearance of lesions. This took place in a period varying from 3 to 8 weeks at the price of unsightly scars in 19 patients. Cutaneous leishmaniasis continues to pose a real public health problem in our country. The emergence of severe and resistant forms throughout the world should encourage the multiplication and strengthening of prophylactic measures
