One-Way Analysis and Correlation Analysis of Design Parameter’s Influence on the Work Condition of Vermifilter

Fatima Hamed, Meiyan Xing
Vermifilter, based on earthworm-microorganism synergistic action, could simultaneously achieve the reduction and stabilization of excess sludge environment-friendly. To make vermifilter work more efficiently and steadily, the diameter of ceramsite, filter height, and influent concentration were investigated in this study. The results showed that though larger ceramicite may decrease the rate of suspended solids (SS) reduction and volatile suspended solids (VSS) reduction slightly, it can improve...

Osteopetrosis Case Series from Tanzania

Lee Kapalisya Mwakalinga, Rogers Joachim Temu, Honest Massawe, Mathias Ncheye, Zawadi Mahumbuga, Octavian Allexander Shirima, Mubashir Jusabani, Regnald Shoo, Anthony Japhet Pallangyo
Osteopetrosis is a rare group of sclerosing bone dysplasia characterized by diminished skeletal resorption. Typical osteopetrosis has the hallmark symptom of increased bone mass with related symptoms resulting from increased bone density. The mainstay of diagnosis is clinical and largely depends on the radiographic appearance of the skeleton. In our case series, three adults were studied, presented with history of recurrent fractures on the extremities sustained after low energy injuries, histor...

Detection of blaVIM Gene in β-Lactam Resistant E. coli Isolated from Clinical Samples in Ouagadougou, Burkina Faso

Abdoul Karim Ouattara, Blandine Ouédraogo, Rahimatou Yasmine Wendkuni Tiemtoré, Amana Mètuor Dabiré, Serge Sougué, Jacques Simporé
Escherichia coli, a Gram-negative bacterium, is commonly associated community and hospital-acquired infections, with significant antibiotic resistance implications for public health. This study aimed to detect the blaVIM gene in E. coli strains isolated from the Centre Hospitalier Universitaire Pédiatrique Charles De Gaulle (CHUP-CDG) in Ouagadougou, Burkina Faso. E. coli strains were isolated from various biological samples (urine, pus, blood, stool, and c...

Melioidosis a Rare Cause of Infective Endocarditis: A Case Report

Chun Kiat Ng, Anuradha P. Radhakrishnan
Burkholderia pseudomallei is an unusual causative organism of infective endocarditis. We present a case of Melioidosis mitral valve endocarditis with dissemination to the liver and kidney in a young woman with underlying SLE with lupus nephritis. Despite the delay in reaching a diagnosis, the patient was successfully treated with intravenous Ceftazidime and oral trimethoprim-sulfamethoxazole and was discharged well. The identification of the specific aetiologic organism is important for t...

The Ancestors of Cryptococci Appeared on Earth 600 Million Years Ago

Petr Nikolayevich Kolosov
The purpose of the research is to study the early forms of life in the Neoproterozoic. To achieve this goal, the author has conducted the search for microfossils in stromatolites and has systematically identified the detected forms. In Eastern Siberia, 600-million-year-old Neoproterozoic rocks host columnar stromatolites. They were formed in the sublittoral areas of the warm sea and consisted almost entirely of mineralized (silicified) remains of yeast fungi that, during their life cycle, parasi...

Antibiotic Resistance and Phynotypic Detection of AmpC Beta-Lactamase Producing Escherichia coli from Urine of Students Attending Fulafia Clinic

Usman S. Okposhi, Kabiru A. Shuaibu, Chuku Aleruchi, Fatima A. Yusuf, Naja’atu S. Hadi
Escherichia coli also known as E. coli are gram-negative facultative anaerobic, rod-shaped, Coliform bacteria, commonly found in the lower intestine of warm-blooded organisms. This study was designed to determine the antibiotic susceptibility and the phenotypic detection of AmpC beta-lactamase producing Escherichia coli from the urine of students attending FuLafia Clinic, Nasarawa State, Nigeria. A total of 22 urine samples were collected from the students. Eleven (50%) E...

Taxonomy and Characterization of Fungi Isolated from Cocoa Beans during Fermentation in Saf’s Agroforestry System in the Amazon

Mateus Cardoso Barros, Jeferson Santana Quadros, Magnun Antonio Penariol da Silva, Raquel Soares Casaes Nunes
Agroforestry systems (SAFs) are an alternative for sustainable development as they enable the recovery of degraded areas and reduce deforestation, contributing to breaking the cycle of traditional family farming, so common in the Amazon region, which enables the recovery of soils, the increase of organic matter and soil fertility. Cocoa beans are grown and fermented in SAFs. According to the research, the significant appearance of endophytic microorganisms such as fungi in the cocoa bean can ben...

Resonant Absorption of Microwaves by Macromolecules

Boris L. Ikhlov
The objective of the study is to detect the resonant absorption of an ultrahigh-frequency electromagnetic field in the centimeter range by DNA molecules at a frequency corresponding to the natural frequency of torsional vibrations of the DNA helix. Instead of DNA solution, cultures of various bacteria containing DNA were used, for whose DNA spirals the resonant frequencies of torsional vibrations were calculated. The cultures were placed in test tubes or cuvette and irradiated by microwave gener...

A Novel Strain of Moderately Thermophilic Streptomyces from the Fenjiu-Flavor Daqu

Lihong Zhang, Baoyan Guo, Huiqing Yang, Caihui Wang
Fenjiu-flavour Daqu is an important starter to support growth of microorganisms in the fermented process of Fenjiu-flavor liquor. A novel thermophilic microorganism, designated strain gby1, was isolated from Fenjiu-flavour Daqu from Shanxi Xinghuacun Fenjiu Distillery Company Limited, Fenyang country, Shanxi province. The morphological, physiological, chemical taxonomic and phylogenetic characteristics of the strain were described in this paper. The isolate gby1 exhibited higher heat resistance....

Microbiological Control of Internal Surfaces of Appliances in the Butcher’s Cold Chain in Lubumbashi

Chadrack Kabeya Diyoka, Isabelle Kasongo Omba, Ghyslain Ngongo Lambo, Eric Kasamba Ilunga, Prosper Emmanuel Malangu Mposhy, Criss Koba Mjumbe
Introduction: Food contamination with microorganisms can occur at any stage of the process, from food production to consumption, and can be the result of environmental contamination. This study was carried out in order to identify the microorganisms forming the flora and to determine the level of microbial contamination of the internal surfaces of devices in the cold chain of butcher shops. Method: This is a comparative cross-sectional descriptive study of 30 internal surfaces of ten devices in ...
