Interdependence of hepatitis B and C virus infection with M2BPGi marker / Эрүүл мэндийн лаборатори

Introduction@#Over 800,000 people in the world contract HCC each year and approximately 700,000 die from the disease. HCC is the 6th most common cancer in the world. HCC is the 3rd leading cause of cancer deaths in the world. 2/3 of liver cancer deaths are caused by hepatitis. In the U.S, HCV infection is the more common cause of HCC, while in Asia and Africa, HBV is more common. Mongolia ranks first in the world in mortality from liver cancer, indicating the need for early detection and treatment of cirrhosis. Sysmex Corporation has introduced for HISCL series analyser, a new cirrhosis marker M2BPGi of non-invasive, blood-testing. In 2016, the test was introduced at Medipas Hospital in Orkhon province. It is possible to study the advantages and significance of the marker for use in clinical practice.@*Materials and methods@#From a total of 385 patients who underwent M2BPGi marker testing in 2016-2017Medipas hospital laboratory, data from a total of 283 patients tested for hepatitis B and C virus and M2BRGi markers were selected. A comparison of age, sex, and test parameters of a total of HCVab and HBsAg positive 172 patients tested for Total bilirubin, GPT, GOT, GGT, AFP and M2BPGi. HCV Ab, HBsAg, AFP, M2BPGi markers were analyzed by SysmexHISCL-5000 fully automated immunological analyzer, Liver function tests were performed with a fully automatic biochemical analyzer JEOL Biomajesty BM6010/C.@*Results@#Of the M2BPGi marker tested 283 patients 94 (33%) were infected with the C virus, 78 (28%) were with the B virus,11 (4%) were co-infected with B and C viruses, 100 (35%) no any viral infection. Of the 172 patients diagnosed with hepatitis B and C virus infection, 97 (56%) were male, 75 (44%) were female. In terms of age, 72% of the population is over 45 years old.</br> Of the 172 patients, 115 (67%) had M2BPGi marker abnormal or > 1.0 COI. Of the M2BPGi marker abnormal patients, 47 (41%) were infected with the B virus and 68 (59%) with the C virus. In terms of age, 27.7% of hepatitis B patients and 10.3% of hepatitis C patients were under 45 years of age, 72.3% of hepatitis B patients and 89.7% of hepatitis C virus patients were over 45 years of age.</br> Hepatitis B and C viruses are slightly more common in men than in women. The majority of patients infected with the hepatitis virus over the age of 45. The majority of patients with hepatitis virus have abnormal liver function. Increased M2BPGi markers in people under the age of 45 with hepatitis B virus infection are relatively higher for hepatitis B virus infection than for C virus infection.@*Conclusions@#The M2BPGi marker was abnormal in 67% of hepatitis virus infected patients. It has been observed that the probability of an increase in M2BPGi marker is slightly higher in hepatitis C virus infection than in hepatitis B virus infection.

Detection of virulent of Klebsiella isolates from ñlinical samples / Монголын Анагаах Ухаан

IntroductionKlebsiella spp is a well-known opportunistic pathogen associated with nosocomial infections such asurinary tract, septicaemia and pneumonia number of multi-drug resistant strains and infections causedby Klebsiella has progressively increased, causing treatment limitations.GoalIdentify of phenotype of Klebseilla isolates from ñlinical samplesMaterials and MethodsA total of 112 Klebsiella strains were isolated from clinical samples in State Central First Hospital and StateCentral Third Hospital from July 2015 through December 2015. The bacterial isolates were identifi edaccording to cultural characteristics, biochemical test and API20E. The serum resistance, capsule andhypermucoviscosity, cell surface protein (curly), a-hemolysin and ability to form biofi lm were sought byphenotypic assays. Antimicrobial susceptibility was tested by diffusion method.ResultA total of 112 Klebsiella samples were collected. The bacterial isolates were identifi ed according tocultural characteristics, biochemical test and API20E, the results revealed that 16.1 percent isolateswere identifi ed as K.oxytoca all of them 83.9 percent isolates were belong to K.pneumonia. Therewere observed for ampicillin (99 percent), nitrofurantoin (53.6 percent), cepalotin (50.6 percent) and51 percent of isolates were considered as a multiple drug resistant. Serum resistance properties ofK.pneumoniae was resistance 89.4 percent, intermediately susceptible 4.3 percent, sensitive 6.4percent and for K.oxytoca resistance 88.9 percent, intermediately susceptible 5.6 percent, sensitive 5.6percent. The hemolysin àalpha was detected in 32.2 percent, and gamma, beta in 66.96 percent, 0.9percent respectively. The capsule was observed in 46.5 percent and hypermucoviscosity in 27.7 percentof isolates. The cell surface protein (curly) and biofi lm were detected in 100 percent.Conclusion:Both K.pneumoniae and K.oxytoca isolates from clinical samples have similar virulent properties, andthe a-hemolysin and hypermucoviscosity positive isolates were more resistance to antibiotics.

Relation between adherence factors and the phylogenetic group of extraintestinal pathogenic Escherichia coli / Шинэ санаа Шинэ нээлт

Extraintestinal pathogenic Escherichia coli (ExPEC), the specialized strains ofE.coli that cause most extraintestinal infections, represent a major but littleappreciated health threat. Phylogenetic analysis has shown that ExPEC is composedof four main phylogenetic groups (A,B1, B2, and D) and that virulent extraintestinalstrains mainly belong to groups B2 and D.In this study, we aimed to assess therelation between adherence virulence and phylogenetic groups of ExPEC.A total of 161 E.coli samples were collected. Out of these 17 (10.6%) werefrom pus, 66 (41 %) from urine, 78 (48.4%) from cervical swab. The phylogeneticgroups and 6 virulence genes (fimH, papC, papGII, papGIII, fa/draBC,andSfa/focDE) encoding adhesins were identified by triplex PCR. Phylogeneticgroups distribution was as follows: B1 10.5%, A 24.7%, B2 25.3%, and D 38.9%. Virulence genes prevalence was fimH 90.1%, papC 23%, papGII 16.8%, papGIII1.9%, Afa/draBC 11.8%, andSfa/focDE 5.6%. The cell surface protein (curli) wasdetected 50,3% by Congo red agar. In conclusion: The most isolated strainsbelonged to the phylogenetic group B2 and D. The phylogenetic groups weresignificantly associated with some genes encodingadhesins (fimH, papC) and cellsurface protein (curli).
