Detection and quantification of SARS-CoV-2 in wastewater using a mobile laboratory setting.

This study evaluated a point-of-care device for wastewater-based epidemiology (WBE) of SARS-CoV-2 circulation. WBE is a critical tool but faces challenges such as laboratory infrastructure, sample transport, skilled personnel, and time-consuming methods. Currently, a rapid, portable solution for wastewater surveillance is lacking.

Metagenomic sequencing for investigation of a national keratoconjunctivitis outbreak, Israel, 2022.

BackgroundEpidemics of keratoconjunctivitis may involve various aetiological agents. Microsporidia are an uncommon difficult-to-diagnose cause of such outbreaks.AimDuring the third quarter of 2022, a keratoconjunctivitis outbreak was reported across Israel, related to common water exposure to the Sea of Galilee.

Ecology of Leishmaniasis in an urbanized landscape: Relationship of sand fly densities, and Leishmania tropica infection rates with reservoir host colonies.

Urbanization may influence the transmission of leishmaniasis, which is as a serious public health issue in Palestine. Semi urban environments can provide suitable habitats for the reservoir host species and the vector sand flies to create favorable condition for disease transmission. This study was aimed to evaluating the effect of distance from hyrax (reservoir host) colonies on sand fly (vector) abundance and its relationship to Leishmania infection within a semi urban landscape.

The spatial and temporal distribution, species composition, and host preference of phlebotomine sand flies in the Bethlehem District of Palestine.

In the Palestinian West Bank, leishmaniasis is emerging as a serious public health issue with incidence increasing over time, especially in the western and the northern parts. This study was aimed to evaluating the effect of altitude on sand fly density, temporal and spatial distribution, species composition, and host preference within and between three villages in the Bethlehem District. The three villages occur along an elevation cline, ranging from the disease-free area of Kisan (KIS; 732-782 m ASL), down to the endemic areas of Arab Ar-Rashaiyda (AAR; 522-568 m ASL), and Al'Azazma (AZA; 473-510 m ASL) in the Bethlehem District (southeastern West Bank).

Plant-feeding phlebotomine sand flies, vectors of leishmaniasis, prefer .

Blood-sucking phlebotomine sand flies (Diptera: Psychodidae) transmit leishmaniasis as well as arboviral diseases and bartonellosis. Sand fly females become infected with parasites and transmit them while imbibing vertebrates' blood, required as a source of protein for maturation of eggs. In addition, both females and males consume plant-derived sugar meals as a source of energy.
