Through field studies on the campus grounds from June to October 2021, 60 samples were collected from which 40 species were identified by morphological characters, belonging to 33 genera, 26 families, and 10 orders. Most species were identified from the order Agaricales and the highest frequency (83.33%) from the orders Polyporales and Agaricales. The highest species abundance was 83.33% for Ganoderma spp., Crepidotus applanatus and the density was 70% for Marasmiellus candidus. The dominant species were Ganoderma spp., Coprinus disseminates, Marasmius spp., Schizophyllum commune, Calvulina coralloides. The wild mushrooms were prevalent in the natural forest areas of the Jahangirnagar University campus. As far as we are aware, this report is the very first work on wild mushrooms or macro-fungi on the campus of Jahangirnagar University.

The incidence of typhoid fever remains high in rural areas and the emergence of multidrug resistance has exacerbated the situation. The present study examined the antimicrobial susceptibility patterns of Salmonella typhi to the antibiotics commonly used in Bangladesh. This study also examined the status of prescription antibiotic use. From July 2016 to June 2017, a total of 40 bacterial pathogens were isolated from blood samples from 100 clinically suspected patients at a teaching hospital in Savar, Dhaka. The blood samples were subjected to analysis byWidal test, microscopy, culture and susceptibility testing using conventional bacteriological methods. A total of 40% of cases had an established bacterial etiology with S. typhi. The highest antimicrobial susceptibility to S. typhi was observed for meropenem (77.5%), gentamicin and imipenem (72.5%), and cefotaxime (70%), respectively. The maximum resistance was observed in the penicillin group, such as (80%) followed by cotrimoxazole (75%). Carbapenem-type beta-lactam antibiotics (meropenem, imipenem) and third-generation cephalosporins (cefotaxime, ceftriaxone, and ceftazidime) were the most effective drugs for typhoid fever. Prescription survey results in four cities in Bangladesh showed that typhoid patients were mainly prescribed third-generation cephalosporins such as cefixime (36.73%) and ceftriaxone (18.37%). The findings are important for an adequate identification of the pathogens and their antibiotic resistance for the correct selection of antibiotics in typhoid fever. The study has implications for the development of guidelines for prescribing antibiotics for typhoid fever in Bangladesh. \u0000Jahangirnagar University J. Biol.

The endophytic fungus-Daldinia eschscholtzii (Ehrenb.) Rehm. was identified based on the morphological and molecular characterization using the ITS-rDNA sequence. Various solid culture media were used to assess the fungal growth, and temperature regimes i.e., 15℃, 20℃, 25℃, 30℃, 35℃ were investigated. The fungal endophyte showed maximum mycelial growth on Potato Sucrose Agar followed by Potato Dextrose Agar and Carrot Agar media. Optimum growth and development of the endophyte was recorded at temperature 25 to 35℃. We observed the effect of five different pH conditions, viz., 5, 6, 7, 8, 9 on the mycelial growth of the fungus. However, the fungal endophyte was very insensitive to the pH of the substrate. To the best of our knowledge, this is the first known occurrence of D. eschscholtzii as an endophyte in Aloe vera in Bangladesh. \u0000Jahangirnagar University J. Biol.

Both cultivars have a simple chromocenter type of interphase nuclei and a gradient type of prophase chromosomes, indicating that they descended from a common ancestor. In addition, both strains were found to have 2n=18 chromosomes with an almost identical range of chromosome lengths. In terms of overall length, the white snow cultivar is almost 7 m shorter than the fresh market cultivar, indicating the presence of chromatin length diversification between specimens. In none of the cases was there a noticeable gradual decrease in chromosome length. The metacentric and submetacentric chromosomes were observed in both samples examined. Apart from other karyotypic features, TF, Syi and AsK % indicate the moderately symmetrical nature of the karyotype. As a result, the two cultivars of cauliflower were moderately primitive in nature.

Breeding activities of starling in JU campus started in late February and continued to early September. A total of 105 nests were recorded in two breeding seasons. The nests were loosely constructed out of straw into the shape of a dome with an entrance on the side. The average nest depth was 18±4.5 cm (n=21, range =12-29 cm) with a mean entrance diameter of 7.6±1.3 cm (n=21, range= 6-10 cm). Most of the nests (98%) were found in trees (98%), only 2% of them were found on the electric poles (2%). Overall, 17 tree species were utilized by the starlings for nesting and majority of the nests were found in Albizia procera (n=25), Gmelina arborea (n=17), and Swietenia mahagoni (n=13).

Result indicated that Pestalotiopsis sp. showed the highest radial mycelial growth on potato dextrose agar (PDA) medium. The utmost vegetative growth of the identified fungus was recorded at 25℃ on PDA medium, however, a range of temperature may be suitable for the fungal growth.
