RESUMEN

BACKGROUND: Agadir city plans to reuse treated wastewater on a large scale to irrigate these green spaces. This study aims to evaluate the risk of intestinal parasites, to which human and animal populations are exposed during the reuse of treated wastewaters. METHODS: Over 21 months, wastewater samples were collected in Bensergao and Mzar wastewater treatment plants, in Agadir city, southern Morocco. The occurrences and removal of intestinal parasites were inspected using the modified Bailenger method. RESULTS: The biodiversity of helminths is higher than protozoa, while the protozoa cysts are more abundant and more prevalent. Generally, the highest parasitic loads were recorded during the hot season. For raw waters, the average concentration of protozoa cysts was 173.33 ± 70.81 cysts per L for Bensergao plant and 179.33 ± 129.22 cysts per L for Mzar plant. However, the helminths average concentration was 48.70 ± 39.91 eggs/larvae per L for Bensergao plant and 51.10 ± 31.76 eggs/larvae per L for Mzar plant. The purified water of the Mzar plant does not contain parasites, unlike the Bensergao plant where a small numbers of parasites were detected, included 2.33 ± 1.53 cysts per L for protozoa and 0.45 ± 0.58 eggs/larvae per L for helminths. CONCLUSIONS: Considering parasitological risks, the purified waters of Bensergao plant cannot be used without risks to the public health and environment. In contrast, the purified waters and the purified waters disinfected by ultraviolet radiation from the Mzar plant can be used safely to water the green spaces of Agadir city.

RESUMEN

Protostrongylids, small nematode lungworms, are an integral part of the wild ruminant helminth community, which can damage animals' health when they are held in captivity or semi-captive conditions. The Sahelo-Saharan antelope species dorcas gazelle (Gazella dorcas), the scimitar-horned oryx (Oryx dammah), and the addax (Addax nasomacculatus), reintroduced to Souss-Massa National Park in Morocco, could be host to many species of Protostrongylids. This study was conducted from January to July 2015 to identify infecting parasite species, and determine their prevalence and abundance in all three antelope species. A total of 180 individual fecal samples were collected, morphologically examined by the Baermann technique, and molecularly identified by PCR amplification and sequencing of the second internal transcribed spacer region of the rDNA (ITS-2). Two parasite species were found in the three antelope populations: Muellerius capillaris and Neostrongylus linearis. The prevalence scores recorded for M. capillaris were 98.40 % in the addax, 96.70 % in dorcas gazelle, and 28.40 % in the oryx. The prevalence rates of N. linearis were 60 % in the addax, 23.40 % in dorcas gazelle, and 90 % in the oryx. Excreted larvae were quantified by LPG (larvae per gram) counting: for M. capillaris, the LPG mean values were 92.94 in the addax, 133.09 in dorcas gazelle, and 1.48 in the oryx; and for N. linearis, the LPG mean values were 6.02 in the addax, 1.37 in dorcas gazelle, and 32.81 in the oryx. These findings indicate that the three species of antelopes are infected with Muellerius capillaris and Neostrongylus linearis to varying degrees in intensity and prevalence.

RESUMEN

The aim of our work is to study dimethoate effects on thyroid function given in drinking water (40 mg/kg body weight, equivalent to 0.2 g/L) to mothers from day zero until the 10th day after delivery. Pups and their mothers were sacrificed on day ten after parturition. Compared to a control group, dimethoate-treated pups showed a 48% decrease in body weight which could be attributed to a defect in thyroid hormones. Indeed, after treatment by dimethoate, plasma rates of free T4 and T3 decreased by 56% and 40% in the young and by 27% and 15% in dams respectively. We can attribute the reduction in plasma thyroxine and triiodothyronine rates to a decrease in thyroid iodine levels (-75%) in the young and (-24%) in their mothers. The decrease in production of thyroid hormones after dimethoate treatment affect thyroid stimulating hormone (TSH) levels. In fact, plasma TSH levels were multiplied in dimethoate-treated group by factors of 2.31 in dams and 1.96 in their offspring. These biochemical modifications confirmed the histological thyroid aspects of pups and dams. In fact, in dimethoate-treated rats, some thyroid follicles of pups presented vesicular cavities without colloid; others contained colloid. However in dams, thyroid follicles presented cubical epithelial cells which surrounded empty vesicular cavities.

RESUMEN

The partition of cells in a polyethylene glycol-dextran two phase system was used to compare the relative hydrophobicity of E. coli strains expressing different surface structures. The role of fimbriae and surface antigens on the behavior partition was investigated. The strains expressing PAP fimbriae and/or O-antigen showed a higher surface hydrophobicity than strains which express only type 1 fimbriae and/or R-antigen. No relation was found between K and H antigen and hydrophobicity measurements. The influence of surface structures on electrophoretic mobility has been evaluated. The polysaccharide capsules of AL 213 and AL 499 strains generated a high EPM. For non capsulated E. coli the EPM of rough strains (AL 46, 382) is higher than smooth strain (AL52).

RESUMEN

We report a case of asymptomatic right diaphragm agenesis, in a 20-year-old adult hospitalized for internal bleeding. This kind of malformation is rare, particularly in adults thus it must be recognized. Imaging modalities are the main tool for diagnosis. It may be suggested by chest X-Ray US, baryum opacification and CT allow to establish a definite diagnosis depicting the herniated organs. The treatment is surgical and the prognosis is in general good.

The authors report, in a retrospective study 11 cases of thoracic extra-pulmonary hydatic cyst observed during 4 years of pneumopathology practice. They stress the rarity of this localization and the variability of the clinical data. Chest X-Ray was found no specific whereas, computed tomography led often to the right diagnosis and helped in some cases a puncture of the hydatic cyst.

RESUMEN

Phaeochromocytoma is an endocrine neuroectodermal tumour usually located in the adrenal gland, but occasionally arising in other organs. The authors report a case of a vesical phaeochromocytoma presenting with haematuria. Radiological and endoscopic investigations revealed a right laterovesical submucosal tumour. Partial cystectomy was performed. The normality of the postoperative endocrine survey suggested disappearance of the tumour and absence of any other sites.

RESUMEN

Recurrent multifocal periostosis of childhood is an infrequent disease. All cases reported to date have been sporadic. A familial form affecting three siblings is reported herein. Clinical and biologic features were similar to those described in the previously reported cases. This case is of particular interest for two reasons: 1) the pattern of familial clustering suggests autosomal recessive transmission; 2) repeated CT scans were performed in these patients (but not in previously reported cases) and demonstrated early involvement of the three bone layers, suggesting panostosis rather than periostosis.

RESUMEN

The authors report the case of a 30 year-old man on whom the diagnosis of hydatic cyst of the heart (HKC) was strongly suspected on bi-dimensional echocardiography and confirmed by surgery. This case is interesting because this HCH, completely latent clinically, was discovered by echocardiography performed in view of a localized infra-epicardic ischemia, the major contribution of bi-dimensional electrocardiography enabling to make a quick and easy anatomical and topographic diagnosis, the primary nature of this hydatic localization which does not affect any other organ, and finally the multivesicle aspect of the cyst, rather unusual in single localizations of hydatic cyst of the heart. A brief review of the literature is then presented.
