A Comprehensive Pathophysiologic, Histologic, and Biochemical Analysis of (C. L. Koch, 1839) Venom.

Introduction: species, including , are classified as one of the most dangerous scorpion genera in Morocco, implicated in several cases of human death. Our objective is to characterize, for the first time, the toxicity and histopathologic and biochemical impacts of venom.

Methods: We investigated the experimental pathophysiology of venom by examining histologic changes in vital organs (heart, kidneys, liver, and lungs) and assessing biochemical enzymatic markers (alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, creatine phosphokinase, urea, and creatinine) in mice injected subcutaneously with 2 doses of 400 and 450 mg·kg.

Enteric parasites in free-living Mediterranean pond turtle (Mauremys leprosa leprosa) in contrasted areas (natural vs polluted) from central-western of Morocco.

The objective of this study is to assess the occurrence of intestinal parasites in Mediterranean pond turtle Mauremys leprosa leprosa collected from three contrasting environments in Morocco. Stool samples from 92 turtles were examined for parasite detection and enumeration. The identified intestinal parasites belong to helminths (oxyurids and ascarid) and protozoa (Entamoebidae).

Epidemiological, toxicological and physiopathological characteristics of scorpion stings and their management in Morocco: A literature review.

All around the world, scorpion envenomation represents a public health issue. In Morocco, it represents the first cause of poisoning. The aim of this review is to highlight the epidemiological, toxicological and physiopathological characteristics of scorpion stings and envenomation in Morocco as well as their management.

Assessment of SARS-CoV-2 Stability in human and environmental matrices, and potential hazards.

In the context of the ongoing pandemic of COVID-19, SARS-CoV-2 was detected in human excreta and environmental matrices. The occurrence of SARS-CoV-2 in environmental compartments raises questions on its fate and stability in these matrices and its potential to spread in the exposed communities. This review focused on the stability of the SARS-CoV-2 in human excreta, wastewater, soils, crops, and other environmental matrices, that may be reached through human excreta and sewage products spreading.

Epidemiological features of cutaneous leishmaniasis in diagnosed patients from an endemic area (central Morocco).

Cutaneous leishmaniasis represents the most neglected tropical disease across the world. In Morocco, this disease is endemic and constitutes a major public health problem, with a national control program been implemented. The current study aimed to determine the pattern and epidemiological features of cutaneous leishmaniasis in affected patients in an area covered by the CL control and prevention program (Central Morocco).

Occurrence of SARS-CoV-2 in excreta, sewage, and environment: epidemiological significance and potential risks.

The detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients' excreta raises the issue of its occurrence and fate in sewage. This review has focused on the presence of the SARS-CoV-2 in human excreta, wastewater, sewage sludge, and river waters. It explored the potential use of the wastewater-based epidemiology approach to report on the situation of current and eventual future SARS-CoV-2 outbreaks.

Pathogenic parasites in sewage irrigated crops and soil: pattern of occurrence and health implications.

The current study aimed to determine the contamination level by human parasite eggs and cysts of sewage-irrigated soil, food crops and fodder crops. Field trials were conducted on spray-irrigated lettuce and flood-irrigated crops using raw wastewater and fresh water. Findings showed that irrigation by raw wastewater led to crops contamination with parasite eggs and cysts in varying levels.

The pattern of cystic echinococcosis in children in an endemic area in Morocco.

Cystic echinococcosis is a parasitic infection of major public health concern. The infection is generally acquired during childhood and the disease incubation period can last many years. The occurrence and characteristics of the disease in children were not well studied.

[Imported Malaria in the Region of Marrakech-Safi, Morocco, between 1996 and 2016].

Since the elimination of the autochthonous malaria in Morocco in 2005, the control of imported malaria, based on epidemiological monitoring of the parasite carriers and on vector control, is a priority. This retrospective study is focused on imported malaria cases identified by optical microscopy at the Laboratory of Public Health in Marrakesh, Morocco, from 1996 to 2016. 208 cases were observed.

Entomological inventory of Phlebotomine sand flies and epidemiological study of leishmaniasis in Afourer, Azilal province, High Atlas, Morocco.

In Morocco, leishmaniases are a major public health problem due to their genetic diversity and geographical distribution. Cutaneous leishmaniasis caused by L. tropica is endemic in the center of the country; it has a high risk of transmission, with Phlebotomus sergenti as vector.

Assessment of the health hazards associated with wastewater reuse: transmission of geohelminthic infections (Marrakech, Morocco).

To address the problem of water scarcity, wastewater has long been used for agricultural purposes in Marrakech (Morocco) and its benefits have long been recognized. However, the benefits of urban wastewater reuse may be limited by its potential health hazards associated essentially to the danger of transmission of pathogenic organisms to human beings. The current study aimed to evaluate the risks associated with raw wastewater reuse for agricultural purposes, and the incidence of geohelminthic infections among the children of the wastewater spreading area of Marrakech as compared to a control group.

Health effect of human wastes use in agriculture in El Azzouzia (the wastewater spreading area of Marrakesh city, Morocco).

The use of wastewater and excreta in agriculture constitutes an important source of spread Salmonella strains and protozoan infections into the environment. This practice has been used in El Azzouzia (the wastewater-spreading area of Marrakesh city, Morocco) for several years. The available circumstantial evidence gained from epidemiological and microbiological investigations suggests that the use of untreated wastewater causes an excess of protozoan infections among children living in El Azzouzia (72%) compared with those from a control area (45%).

Health effect of wastewater reuse in agriculture.

The present study addresses the impact of wastewater reuse in agriculture on the transmission of protozoan and helminthic infections. For this purpose, an epidemiological study was carried out on two populations of children totalling 608 individuals for protozoan infections and 528 for helminthic infections. Each population comprised an exposed group living in the wastewater spreading area of Marrakech and a control group.

The effect of waste water reuse in irrigation on the contamination level of food crops by Giardia cysts and Ascaris eggs.

In Marrakech, raw sewage has been used for farming purposes for several decades for many types of crops. This study aimed to determine the contamination level of Giardia cysts and Ascaris eggs for crops designated for human consumption. Collected crops in irrigated fields were turnip, marrow, squash, potatoes, pepper and eggplant.
