Background: Coronaviruses are large groups of viruses that cause illness in humans and animals. This virus has a higher degree of lethality than other endemic viruses Covid-19 diagnosis is based on viral detection, isolation, or serological changes. For cytopathic effects, sputum cytology is routinely performed for nearly all patients with chest symptoms. Objective: The study aimed to find Cytological change in sputum samples of COVID -19 patients in Shendi town. Materials and Methods: This study includes 45 subjects. Thirty were known as Covid 19 positive cases by PCR, and 15 were healthy subjects. Two sputum smears were collected from the study group then fixed in (95% Ethanol alcohol) and stained with Papanicolaou and Giemsa stains, then screening for any cytomorphological changes and microbes. Result: In cytology screening, intranuclear inclusion and inflammatory cells were observed in all sputum samples (100%) of patients infected with covid-19, other cytomorphological changes that appeared were nuclear atypia (96.6%), cytolysis (64.4%) and destructive change (fibrocytes) in (30%). None of the cytomorphological changes mentioned above were observed in the control sample. Co-infection with bacteria and fungi (aspergillus & Candida) exists in (66.6%) of Covid-19 patients. There was a statistically significant correlation between infection with covid-19 and the cytomorphological changes characterized in their sputum P. value was less than (0.05). Intranuclear inclusion in this study was a specific and sensitive indicator for Covid-19. There was no correlation between the period of infection and distractive change appearance or invasion with micro-organisms of the study group (P. value more than 0.05), But confections with microorganisms were statistically correlated to the age of the study group (P. value less than 0.05). Conclusion: Cellular changes and consistency of Sputum and saliva samples can provide inexpensive, rapid diagnostic, minimally invasive techniques for Covid-19, particularly in densely populated developing countries and areas.

Background: Operating room contamination is recognized as one of the most common life-threatening microbial contaminations in hospital environments, especially operating rooms and other specialty units, and is an ever- increasing cause of nosocomial infections. Objective: The purpose of this study was to isolate and identify bacterial contaminants in Shendi hospital operating room. Between July-September 2021. Materials and Methods: Sixty samples were collected from various locations in the operating room and all isolated bacteria were identified. The study isolated five types of bacteria from the Shendi Hospital operating room. Results: The results showed that Micrococcus was the most common bacterial contaminant isolated from the operating room. Leteus 21 (32.3%) Staphylococci. Epidermis 16 (24.6%), Staphylococci aureus 11 (16.9%), Bacillus sp. 9 (13.8%), Bacillus cereus 8 (12.3%)) and the lowest contaminants were isolated from soil 15 (23%), and focus lamp 5 (7.7%). This study may point to the fact that the Shendi Hospital operating room had bacterial contamination that could lead to postoperative wound infections (SSI). Reasons for contamination may be due to excessive attendance, personnel movement, and ineffective sterilization and disinfection procedures. Conclusions: Bacterial contamination was highest in operating room beds, followed by carts, floors, and focused lambs. Micrococcus spp, S. epidermidis, S. aureus, and Bacillus species have proven to be the most serious contaminants in the operating room, and are a dangerous cause of hospital-acquired infections, killing patients and hospital staff threatening. This may indicate that the sterilization method is not efficient enough, putting the patient at risk for postoperative infection. Some organisms were resistant to Gentamicin and highly sensitive to Imipenem, Ciprofloxacin, and Ceftriaxone.

Background: Urinary tract infections frequently occur in diabetic patients due to an impaired immune status and increased glucose content in the urine among other reasons. This makes UTIs very important to investigate. Complicated cases of UTI may be frequent but are more common in diabetics with more severe consequences. And so warrant further investigations. The proper management of UTI in diabetics is crucial as prompt diagnosis and correct use of antibiotics are vital for treatment. Finding alternative antimicrobial agents from plant extracts has received growing interest. Ginger (Zingiberofficinale) is a safe, non-toxic, cheap spice that has been reported to have antimicrobial effects against various pathogenic bacteria. Objectives: This study aimed to evaluate the effectiveness of ginger extract on different types of bacteria isolated from diabetic patients suffering from urinary tract infections. Methodology: A cross- sectional and hospital-based study has been conducted at the University of Shendi –faculty of medical laboratory sciences- department of microbiology from May to November 2018. Following informed consent, 100 diabetic patients suffering from UTI of different ages were enrolled in this study. Sixty-two bacteria were isolated, different Gram- positive and Gram-negative bacteria, in vitro sensitivity testing using a well diffusion technique against ginger extract. Results: The main causative agent of UTI in the study population was E. coli 32.3% then S. aureus 29%, S. saprophyticus 29%, and E. faecalis9.7%. The largest diameter of the inhibition zone appeared in Gram-positive S.saprophyticus (13.4mm). The concentrations of ginger extract used were 100, 50, 25, and 12.5 mg/ml. mean of inhibition zone of chloramphenicol for isolated bacteria S.aureus 31mm, S.saprophyticus 20.2 mm, E.coli 17.7mm, and faecalis24.6mm. Conclusion: The antimicrobial activity of the crude extract was compared with that of standard antimicrobial chloramphenicol based on the mean diameter of the inhibition zone. The extract exhibited maximum relative percentage inhibition against S.saprophyticus(42.3%) and minimum relative percentage inhibition against S. aureus (6.3%).
