A filamentous cyanobacterium, Trichormus sp. IMU26, capable of rapid growth and high phycobiliprotein (PBP) production under N2-fixing conditions was isolated. The strain has been maintained in N-free BG-11 medium for more than 20 months upon isolation. Nitrogen supply resulted in higher soluble protein and saccharide content but a lower growth rat...

They have conducted to test the efficiency of fat pomegranate extract supported by Silver nanoparticle (AgNp) to inhibit the growth of Staphylococcus aureus in the study, isolated from teeth decay from March to July 2020. Thirty isolates were purified and identified according to morphological, biochemical, Physiological tests and confirmed by the A...

Abstract: Cyanobacteria are considered as a sustainable feedstock for the production of biochemically active compounds such as phycobiliproteins (PBPs). In this study, impact of nitrogen (N) and phosphorus (P) availability on PBP production of “N-free acclimated” Anabaena variabilis sp. IMU8 was analyzed. Upon isolation and identification, the cyan...

Recently, a new Chlorella sp. has been isolated from Arctic sea and named ArM0029B. Compared to Chlorella vulgaris, this microalgae displays faster growth at a wider temperature range and accumulates higher levels of fatty acids under nitrogen starvation condition (1). Very little is about this known discovered Chlorella sp. but taken together,...

Medicinal plants are an ideal source of a wide range of natural medicines, playing an important role in traditional and modern treatments. Nigella sativa is a medicinal herb known for its antibacterial properties. Thymoquinone (TQ), the primary active compound in its seeds, exhibits antibacterial, antifungal, and antioxidant activities. Research ha...

Background The protozoan parasite Toxoplasma gondii is responsible for the most significant zoonotic illness in the world, Toxoplasmosis. It is possible for T. gondii to be transferred transplacentally from the mother to the fetus if it is contracted during pregnancy and causes abortion or congenital deformity. Objective To investigate the correla...

Background Toxoplasma gondii is an obligatory parasite that causes a zoonotic infection known as toxoplasmosis, which produces a wide range of clinical symptoms in humans and is considered the major cause of abortion in women. Immunocompromised patients are more likely to develop T. gondii infections due to parasite transmission over the placenta....

Asymptomatic Bacteriuria (ASB) is a pathological state distinguished by substantial urinary infection in the absence of any observable symptoms. ASB is a result of the presence of typical gut microorganisms that migrate via the urethra and potentially reach the bladder and kidneys. The diagnosis relies on urine culture, genetic analysis using The P...

The infection of the Urinary tract (UTI) represents the most health problem in the world affecting millions of people every year. E. coli is the most bacterium that causes urinary tract infections in humans. E. coli can because transitory damage of DNA followed by incomplete DNA repair during cell division, so this finally leading to chromosome def...

Cyanobacteria are a group of microorganisms that are known to produce a wide range of biologically active metabolites as well as a wide range of cyanotoxins such as anatoxins. In this study, the biosynthetic gene clusters (BGCs) that are responsible for bioactive secondary compounds production were genetically identified in the whole genome sequenc...

Background Cyanobacteria are a widely dominated group of microorganisms in nature that produce a diverse range of metabolites. Whilst the enormous number of bacterial genomes has deposited in the public databases, the number of cyanobacterial genomes remains limited. Aims This study aimed to sequence the whole genome of an Iraqi cyanobacterium iso...

Cyanobacteria resemble algae in that they contain chlorophyll and then photosynthesize and oxygen is released as a result. Cyanobacteria resemble bacteria in that they are Gram-negative bacteria and their wall consists of peptidoglycan and contain a primitive nucleus and do not contain chloroplasts but membranes called thylakoids that contain the c...

An antibiotic was originally a material created by one microorganism that selectively inhibits another’s development. Since then, synthetic antibiotics have been developed that perform comparable tasks, typically chemically similar to natural antibiotics. There are no effects of antibiotics on viral infections. Antibiotics are used to treat bacteri...

Timothy Syndrome, a rare multisystem disorder, causes various syndromic symptoms and requires a multiorgan approach. Timothy syndrome (TS) often manifests during the neonatal period. However, in many cases, it is diagnosed later, between the ages of 2-4 years. The objectives of our study were to investigate the relationship of Timothy Syndrome and...

Toxoplasma gondii, a parasite that can produce a wide range of clinical symptoms in humans, is the source of the zoonotic infection known as Toxoplasmosis. The goal of this study was to measure the serum levels of anticardiolipin (ACL) antibodies (ACL-IgM and ACL-IgG) in 200 women with T. gondii and recurrent abortions.Two hundred (200) blood sampl...

Epstein-Barr Virus (EBV), or Kissing Virus, is a member of the Herpes virus that can be a contributory factor for compromised pregnant, high-risk aborted women worldwide. The present study aimed to detect high-risk EBV by the Monospot test for pregnant, high-risk aborted women, to detect immunoglobulin IgM and IgG for EBV using Enzyme-linked immuno...

This research refers to the study effect of vibration resulting from the rock crushing device on human health by studying the effect on the blood parameters of workers on this device for a period ranging from ten years and above. Samples were collected from people working in rock breakers (Jackhammer) in several areas of the province on 10/5/2020 a...

This study examined the docking of two inhibition for SARS-Cov-2 virus (or COVID-19) these proteins are (6wtt and 6xa4) with nine pharmaceutical compounds (Aminoglutethimide, 4-Aminosalicylic acid, Felbamate, Hydroflumethiazide, Modafinil, Nepafenac, Oxcarbazepine, and Trichlormethiazide) which are used in the general human's life. These pharmaceut...

Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) or Coronavirus 2019 (COVID-19) has been involved in cases of moderate to severe respiratory system diseases. The World Health Organization "WHO" has reported that infections with COVID-19 are a global pandemic. Aim of our study was designed to study the relationship of some biochemical pa...

A sample of the bread yeast Saccharomyces cerevisiae strain was taken from the local markets in the city of Mosul and grown on the appropriate medium for it in order to test its ability to remove some heavy metals. Concentrations for each metal ph and three temperatures The grown bread yeast was able to remove both zinc and lead alone and remove th...

Biosensors especially DNA biosensors find use in diverse fields like clinical, food adulteration prevention, and in the monitoring of the environment. The DNA based biosensors have gained prominence in detection and monitoring and are the ultimate choice due to their high sensitivity and selectivity. Novel synthetic probes have been exploited for t...
