Marine fungal community composition and diversity across a polluted site in the south Mediterranean coast: the Monastir Bay, Tunisia.

Marine fungi communities play a crucial role in the recycling of nutrients, restoration of biological systems, and the overall functioning of ecosystems. While aquatic fungal communities do react to pollution, there is a significant lack of information regarding the changes in the fungal community's structure, caused by marine pollution. In this study, we aim to address this gap in knowledge by investigating the range and makeup of fungal species present in marine environments in a polluted bay in Tunisia, spanning a biodiversity hotspot (Monastir Bay).

Clinical polymorphism of zoonotic cutaneous leishmaniasis: combination of the clinical and the parasitological diagnosis.

Zoonotic cutaneous leishmaniasis (ZCL) is a neglected tropical disease caused by Leishmania (L.) major. This zoonosis is characterized by a broad-spectrum clinical polymorphism and may be underestimated and poorly treated since it is a simulator of various dermatoses.

Epidemiological Profile of Urinary and Intestinal Schistosomiasis in the Kingdom of Saudi Arabia: A Seven-Year Retrospective Study.

Background: Despite the marked decline of schistosomiasis in Saudi Arabia in recent years, it is still reported in several regions. This study investigates the epidemiology of schistosomiasis in Saudi Arabia over seven years (2014-2020).

Methodology: A retrospective study was retrieved from the annual reports of the Ministry of Health.

On abnormal Phlebotomus perniciosus (Diptera: Psychodidae: Phlebotominae) from the center of Tunisia.

Phlebotomus perniciosus is the most important vector of Leishmania infantum in the Western part of the Mediterranean basin. Atypical specimens of Ph. perniciosus called (pna) with a parameral sheath simply curved, not bifurcated, have been reported in many locations.

Blood meal analysis and molecular detection of mammalian Leishmania DNA in wild-caught Sergentomyia spp. from Tunisia and Saudi Arabia.

Phlebotomine sand flies (Diptera: Phlebotominae) belonging to the genus Phlebotomus are vectors of pathogens such as arboviruses, bacteria, and parasites (Leishmania). Species of the genus Sergentomyia (Se.) transmit Sauroleishmania (Reptile Leishmania) and feed on cold-blooded vertebrates; recently, they have been incriminated in mammalian Leishmania transmission.

Identification of cuticle and midgut fungal microflora of phlebotomine sandflies collected in Tunisia.

Phlebotomine sand flies (Diptera: Psychodidae) are the proven vectors of Leishmaniases which are widespread parasitosis in many tropical and subtropical countries. The development of infective metacyclic Leishmania (Kinetoplastida: Trypanosomatidae) promastigotes stage is restricted to the vector midgut. Recently, several studies have assessed the influence of the sand fly midgut fungal microflora on the development of invective Leishmania stage.

In Vitro Assessment of Azole and Amphotericin B Susceptibilities of spp. Isolated from Healthy and Lesioned Skin.

yeasts have recently gained medical importance as emerging pathogens associated with a wide range of dermatological and systemic infections. Since standardized methods for in vitro antifungal susceptibility testing have not yet been established for spp., related diseases are always treated empirically.

Virulence factors of Malassezia strains isolated from pityriasis versicolor patients and healthy individuals.

Unlabelled: Over the last decade, Malassezia species have emerged as increasingly important pathogens associated with a wide range of dermatological disorders and bloodstream infections. The pathogenesis of Malassezia yeasts is not completely clear, but it seems to be strictly related to Malassezia strains and hosts and needs to be better investigated. This study aimed to assess the enzymatic activities, biofilm formation and in vitro antifungal profiles of Malassezia spp.

Coping during COVID-19 Pandemic in Saudi Community: Religious Attitudes, Practices and Associated Factors.

The COVID-19 pandemic has affected many societies' life aspects and activities including social and Islamic practices; more attention should be given to investigate the interaction between Islamic worships and the spread of the disease. Here, we performed a cross-sectional study using an online questionnaire to assess the preventive Islamic attitudes and practices during the COVID-19 lockdown period from the Saudi publics' perspectives. Mann-Whitney, Kruskal and logistic regression tests were used to analyze the data.

Intestinal parasitic infection among foreign housemaids in northwestern Saudi Arabia: A cross-sectional study.

Owing to Saudi Arabia's high-income economy many Saudi families hire foreign housemaids. However, since the housemaids are potential carriers of intestinal parasites, hiring them increases the risk of transmission to the Saudi community. In this context, this study aimed to evaluate the prevalence of intestinal parasitic infections in foreign housemaids in northwestern Saudi Arabia.

Molecular detection and identification of Leishmania DNA and blood meal analysis in Phlebotomus (Larroussius) species.

Background: Phlebotomus (Larroussius) perniciosus and Canis familiaris are respectively the only confirmed vector and reservoir for the transmission of Leishmania (L.) infantum MON-1 in Tunisia. However, the vector and reservoir hosts of the two other zymodemes, MON-24 and MON-80, are still unknown.

Transmission cycle analysis in a Leishmania infantum focus: Infection rates and blood meal origins in sand flies (Diptera: Psychodidae).

An entomological study was conducted in a Leishmania infantum focus, including the identification of the sand fly species, the detection and the characterization of Leishmania DNA in female sand flies, and blood meal origins in engorged sand flies. A total of 643 sand flies (31% female, 69% male) was identified based on their morphological features or molecular markers. Ten different species were identified, with Phlebotomus perniciosus, the confirmed vector of L.

The vector competence of Phlebotomus perniciosus for Leishmania infantum zymodemes of Tunisia.

Experimental infections of Phlebotomus (L.) perniciosus from a colony established in Madrid (Spain) carried out with the Leishmania (L.) infantum zymodemes MON-1, MON-24, and MON-80 isolated in Tunisia are reported here.

Cutaneous leishmaniasis in northwestern Saudi Arabia: identification of sand fly fauna and parasites.

Background: Cutaneous leishmaniasis (CL) is a vector-borne disease transmitted by the bite of an infected sand fly. This disease is highly prevalent in Saudi Arabia where Leishmania major and L. tropica are the etiological agents.

Clinical Presentation of Cutaneous Leishmaniasis caused by Leishmania major.

Background/aims: The diagnosis of cutaneous leishmaniasis (CL) is based on the microscopic detection of amastigote, isolation of the parasite, or the detection of Leishmania DNA. Nevertheless, since these techniques are time consuming and not usually available in many endemic countries, the diagnosis remains clinical. Consequently, such disease may be overlooked because of its similarity to other skin diseases.

Prevalence of intestinal parasite infections among patients in local public hospitals of Hail, Northwestern Saudi Arabia.

Objective: To evaluate the prevalence of intestinal parasites among patients in Hail, Northwestern Saudi Arabia.

Methods: Stool samples were collected from 130 patients (69 females and 61 males) in Hail General Hospital. Each sample was examined by direct wet mount microscopic examination using both normal saline and Lugol's iodine preparation and concentration techniques using salt and formol-ether solutions.
