The microbiology laboratory is one of the vital laboratories in Theodor Bilharz Research Institute. It is concerned in diagnoses of the most important infectious microbes and selection of the appropriate antimicrobial treatment for all patients attending the institute outpatient clinics in addition to inpatients. The lab clinic receives various clinical samples for the performance of culture and sensitivity tests for microbes. The lab also performs serological tests for diagnosis of hepatic viral diseases. The lab combines conventional and automated methods that allow rapid and accurate interventions to treat sepsis at early stage through culture followed by automated identification and sensitivity to isolated bacteria or fungi. In addition to reliable automated detection of important biomarkers of sepsis. It is also concerned in determining resistant infectious bacteria to various antibiotics and their resistance genes and conducting innovative scientific research addressing the global problem by using the most recent diagnostic techniques in molecular biology.
Microbiology department envisages a future where applied microbiology diagnostics and research policies contribute significantly in the community to overcome the emerging infectious diseases challenges including the uprising antimicrobial resistance crisis.
Service :The primary role of a microbiology laboratory is to identify causative agents of various infectious diseases and help and facilitate the justified use of antibiotics. This should be done in a cost-effective and timely manner that enable good and effective patient care.
Teaching :To teach appropriate use of diagnostic laboratory tests and resource utilization in the care of patients through upgrading of technical performance and scientific background of junior staff.
Research :To develop and to evaluate procedures and protocols that support, enhance and extend the ability of Microbiology lab to carry out effectively their primary service in diagnosis and combating antimicrobial resistance.

Current research work focuses on four main categories;
- Detection of multi-drug resistant (MDR) bacteria: Hot topics include researches on carbapenem resistant Enterobacteriaceae and Acinetobacter baumannii isolates as well as resistance among Helicobacter pylori(H. pylori).
- Effect of novel or old reviving therapeutic agents against MDR pathogens: Research work of fosfomycin, doripenem, tigecycline and ceftolozane/ tazobactam against ESBL-producing Enterobacteriaceae have been recently carried out. Running hot topics of colistin susceptibility in carbapenem resistant Enterobacteriaceae as well as carbapenem resistant Acinetobacter baumannii are in progress.
- Rapid diagnosis of septicemia and other life-threatening infections: Comparing various sepsis biomarkers (CRP- presepsin- procalcitonin) with blood culture results as well as with clinical methodology of APACHE score for septicemia is a hot running topic.
- Methods of detection of endemic and various emerging pathogens:Helicobacter pylori, Chlamydia, Mycoplasma, Candida spp as well as nano bacteria have been in our concern in our research work.
Our achievements are unfolding in the form of research projects whether already finalized or underway:
Studies of beta lactamases in Gram-negative bacteria:
- Detection and molecular characterization of various β-lactamases responsible for antimicrobial resistance in multidrug-resistant Gram-negative Egyptian bacterial clinical isolates. Reports of various types of beta-lactamases including extended spectrum beta-lactamases (ESBLs) and carbapenemases have arisen from our Microbiology lab. Reports for the emergence of the intercontinental ST131 coli as well as NDM producing Enterobacteriaceae (NDM-1 and NDM-5) have been released from our research laboratory work.
- Extended spectrum beta-lactamases (ESBLs), metallo-beta lactamases (MBLs) and plasmid mediated AmpC beta lactamase (pAmp-C), detected in our bacterial clinical isolates, both from hospital and community settings, justifies the need for screening Enterobacteriaceae for the production of those enzymes by the simple and accurate diagnostic phenotypic methods utilized in this study.
- A comparative epidemiologic study on the prevalence of faecal carriage of ESBL-producing Enterobacteriaceae in patients with liver disease in Egypt and in France revealed that the prevalence of ESBL in faecal carriers was very high in Egyptian patients (77.5%) compared to 6.5% from French patients within the same study period (May – June 2009). More than 50% of Egyptian patients did not have a history of previous hospitalization, suggesting a very high prevalence of ESBL in the community in Egypt.
- Ongoing projects are directed towards resistance to carbapenem, the most potent beta lactam antibiotic, in Enterobacteriaceae (CPE) and in Acinetobacter baumannii(A. baumannii) in clinical infections as well as in carrier stages. Studies for the detection of these superbugs as well as evaluation of the current available treatment options are in our priorities.
- A significant rate of carbapenemase producing Enterobacteriaceae in was recorded among clinical and colonized patients in TBRI hospital thus providing limited therapeutic options and suggests fast spread in the community.
- NDM-like gene was the main carbapenemase-producing gene found among clinical CPE isolates, whereas OXA-48-like was the predominant gene in colonized ones.
- Going more through more details in CPE isolates, we found IncR plasmids carrying blaNDM-1 and rmtF circulating among our isolates, thus raising concerns regarding this type of replicon and their role in the transmission of these resistance determinants.
Assessment of frequency of pylori virulent factors isolated from different dyspeptic patients:
- pylori infection is highly endemic in Egypt; among dyspeptic patients 53.1% were confirmed to be infected with H. pylori. H. pylori-induced functional dyspepsia is different type from functional dyspepsia. Whereas H. pylori gastric carcinoma is not a common complication may be due to the absence of the East Asian carcinogenic type of cagA in Egypt.
- The overall vacA, iceA1 and cagA virulence genes were revealed (61.6%, 38.8%, 26.6% respectively). Six different genotypic types were recognized; iceA1, vacA/ cagA, vacA/iceA1, vacA/cagA/iceA1 by PCR-based molecular testing. Mutant genes conferring antimicrobial resistance were observed in 25% for metronidazole (rdxA gene), in 18.3%for amoxicillin (pbp1A gene), in 6.7% for clarithromycin (23S rRNA gene) and in1.7% for tetracycline (16S rRNA).
Biofilms and device associated infections: bacteriological and morphological study:
- Associated infections were detected in 55% of patients with indwelling medical devices, culture being positive for 65% of all medical devices.
- Minimal inhibitory concentrations of different antibiotics against cells within biofilms were 10-fold higher than that against planktonic ones.
Emerging viral hepatitis agents in patients with chronic liver diseases and hepatocellular carcinoma:
- Occult HBV infection may increase the severity of chronic HCV infection, accelerate the evolution to cirrhosis and promote the development of HCC. The newly developed quantitative electro-spin-resonance-EIA technique represents a great evolution as alternative to molecular techniques for screening and diagnosis of occult HBV infection.
- Infection with hepatotropic viruses; TTV, GBV-C and SEN-V does not contribute to the severity of liver disease in patients infected with hepatitis C virus nor in causation of HCC.
- Lower HCV RNA levels in HGV coinfected patients raise the speculation of a possible beneficial role for HGV in HCV patients.
Role of viral infections in bladder carcinogenesis:The significant association of CMV, HSV-2 and HPV-16, -18, and -52 with bladder cancer in Egyptian bilharzial patients strongly supports the hypothesis of a viral synergistic action in bladder carcinogenesis.
A new approach for detection of antibodies to Human papilloma virus: Development of rapid, simple and accurate detection EIA kit for early non-invasive diagnosis of the two prevalent cancer bladder Human papilloma-viruses in Egypt (HPV 16, 18). Purified HPV-16 and 18 VLPs, produced by recombinant Baculo-virus, are used as antigens for detection of IgG antibodies in human sera.
