Survey on macro fungi was made in Gajni forest, Sherpur, Bangladesh which is located in between 24°18' and 25°18' north latitudes and in between 89°53' and 90°91' east longitudes. It is bounded by Meghalaya state of India on the north, Mymensingh and Jamalpur districts on the south with a wide range of ecosystem. The survey was conducted on July to December, 2018 to identify and preserve wood-rot causal macro fungi for future industrial utilization. Morphology of basidiocarp and characteristics of basidiospore were recorded. A total of 20 samples were collected and identified to 12 species belonging 7 families. Dominant species was Ganoderma species. The identified four species were from Ganodermataceae family and these were G. applanatum, G. lucidum, G. tropicum and G. lobetum. Other dominant genus was Russula. Other recorded genera were Hebeloma, Boletus, Phlebopus and Entoloma. Among them the highest frequency (85.72%) was recorded for G. applanatum and lowest frequency (7.14%) was recorded for Phlebopus marginatus. Similarly highest density (20.25%) was recorded for Agaricus sp. followed by G. lucidum (15.85%). The lowest density was (2.14%) was recorded for Phlebopus marginatus. Collected specimens were preserved in Sher-e-Bangla Agricultural University Herberium of Macro fungi (SHMF) for further study.

Myasthenic Syndrome

Abstract Congenital myasthenic syndromes (CMS) are associated with defects in the structure and the function of neuromuscular junctions. These rare disorders can result from mutations in the collagenic tail of endplate acetylcholinesterase (COLQ) essentially associated with autosomal recessive inheritance.With the lowered cost of genetic testing and increased access to next-generation sequencing, many mutations have been reported to date. In this study we identified the first COLQ homozygous mutation c.1193T>A in the North African population. This study outlines the genetic and phenotypic features of a CMS patient in a Moroccan family. It also describes a novel COLQ missense mutation associated with CMS-5. COLQ mutations are probably underdiagnosed in these North African populations, this is an issue as CMS-5 may be treated with ephedrine, and albuterol. Indeed, patients can seriously benefit and even recover after the treatment that should be planned according to genetic tests and clinical findings.

Insect Toxicity

Various bioactive peptides have been identified in scorpion venom, but there are many scorpion species whose venom has not been investigated. In this study, we characterized venom components of the North African scorpion, Buthacus leptochelys, by mass spectrometric analysis and evaluated their insect toxicity. This is the first report of chemical and biological characterization of the B. leptochelys venom. LC/MS analysis detected at least 148 components in the venom. We isolated four peptides that show insect toxicity (Bl-1, Bl-2, Bl-3, and Bl-4) through bioassay-guided HPLC fractionation. These toxins were found to be similar to scorpion α- and β-toxins based on their N-terminal sequences. Among them, the complete primary structure of Bl-1 was determined by combination of Edman degradation and MS/MS analysis. Bl-1 is composed of 67 amino acid residues and crosslinked with four disulfide bonds. Since Bl-1 shares high sequence similarity with α-like toxins, it is likely that it acts on Na+ channels of both insects and mammals.

The new species Diabrotica wartensis Cabrera & Sosa-Gómez was found feeding on roots and leaves of sunflower and soybean in the north of the state of Paraná. A set of characters of diagnostic value: mouthparts, hind wing venation, binding patch, metendosternite, and details of male and female genitalia previously overlooked in the genus was provided. In addition to the morphological characterization, the molecular analyses of the COI mitochondrial gene and the ITS-1 rDNA nuclear region were included. The analysis of the ITS-1 nuclear region alone suggests proximity of D. wartensis to the Diabrotica fucata group, whereas molecular evidence based on combined analysis of COI and ITS-1 region suggest that this new species is distantly related to the Diabroticina with known sequences deposited in the GenBank.

Logarithmic Growth

Mycobacteriophage R1 was originally isolated from a lysogenic culture of M. butyricum. The virus was propagated on a leucine-requiring derivative of M. smegmatis, 607 leu−, isolated by nitrosoguanidine mutagenesis of typestrain ATCC 607. Growth was accomplished in a minimal medium containing glycerol and glucose as carbon source and enriched by the addition of 80 μg/ ml L-leucine. Bacteria in early logarithmic growth phase were infected with virus at a multiplicity of 5, and incubated with aeration for 8 hours. The partially lysed suspension was diluted 1:10 in growth medium and incubated for a further 8 hours. This permitted stationary phase cells to re-enter logarithmic growth and resulted in complete lysis of the culture.
