Hard ticks (Acari: Ixodidae) infesting domestic animals in Egypt: diagnostic characters and a taxonomic key to the collected species.

Med Vet Entomol 2021 Jan 16. Epub 2021 Jan 16.

Entomology Department, Faculty of Science, Ain Shams University, Abbassia, Cairo, Egypt.

Ticks are important vectors of emerging health problems in humans and animals. We conducted several field surveillances to investigate the fauna of hard ticks on domestic animals in seven governorates of Egypt during 2018-2019. A total of 3265 individual tick specimens were collected and identified to the species level; the specimens belong to 11 species within three genera (Amblyomma, Hyalomma, and Rhipicephalus).

Woody biomass represents an important source of carbon on earth, and its global recycling is highly dependent on Agaricomycetes fungi. White-rot Basidiomycetes are a very important group in this regard, as they possess a large and diverse enzymatic repertoire for biomass decomposition. Among these enzymes, the recently discovered lytic polysaccharide monooxygenases (LPMOs) have revolutionized biomass processing with their novel oxidative mechanism of action. Read More

Conserved white-rot enzymatic mechanism for wood decay in the Basidiomycota genus Pycnoporus.

DNA Res 2020 Apr;27(2)

INRAE, UMR1163, Biodiversity and Biotechnology of Fungi, Aix Marseille University, 13009 Marseille, France.

White-rot (WR) fungi are pivotal decomposers of dead organic matter in forest ecosystems and typically use a large array of hydrolytic and oxidative enzymes to deconstruct lignocellulose. However, the extent of lignin and cellulose degradation may vary between species and wood type. Here, we combined comparative genomics, transcriptomics and secretome proteomics to identify conserved enzymatic signatures at the onset of wood-decaying activity within the Basidiomycota genus Pycnoporus.

Aims: Red yeast rice (RYR), produced by inoculating Monascus strains to steamed rice, contains many kinds of physiologically bioactive compounds, among which monacolin K can be used as an antihypercholesterolaemic agent. However, RYR can be polluted by the mycotoxin citrinin, which has nephrotoxic and hepatotoxic activities. To avoid the risk of citrinin contamination in Monascus fermented products, it is important to screen for Monascus strains that produce no or low citrinin. Read More

Ticks from diverse genera encode chemokine-inhibitory evasin proteins.

J Biol Chem 2017 09 4;292(38):15670-15680. Epub 2017 Aug 4.

From the Infection and Immunity Program, Monash Biomedicine Discovery Institute, and Department of Biochemistry and Molecular Biology and

To prolong residence on their hosts, ticks secrete many salivary factors that target host defense molecules. In particular, the tick has been shown to produce three salivary glycoproteins named "evasins," which bind to host chemokines, thereby inhibiting the recruitment of leukocytes to the location of the tick bite. Using sequence similarity searches, we have identified 257 new putative evasin sequences encoded by the genomes or salivary or visceral transcriptomes of numerous hard ticks, spanning the genera , , and of the Ixodidae family.
