Diphtheria has been reported as an outbreak in some regions in Indonesia, most especially in East Java Province. Resistance to penicillin, erythromycin, and other antibiotics, single or multiple, has been reported in several studies. This study aims to evaluate the first-line antibiotic susceptibility pattern of toxigenic Corynebacterium diphtheriae isolates. This descriptive observational study was performed from August to November 2018. C. diphtheriae isolates were collected from diphtheria patients and carriers in East Java from 2012 to 2017 and kept at the Balai Besar Laboratorium Kesehatan Daerah Surabaya or the Public Health Laboratory of Surabaya. Sample selection was done by random cluster sampling. The sensitivity test by E-test®of the five antibiotics (penicillin, oxacillin, erythromycin, azithromycin, and clarithromycin) was done to determine the minimum inhibitory concentration (MIC). The Clinical and Laboratory Standards Institute M45A (2015) Corynebacterium spp. for penicillin and

BACKGROUND: The reemergence of epidemic diphtheria in Belarus in 1990s has provided us with important information on the biology of the disease and the diversity of the causative agent Corynebacterium diphtheriae. Molecular investigations were conducted with the aim to analyze the genetic variability of C diphtheriae during the post-epidemic period. METHODS: The biotype and toxigenicity status of 3513 C. diphtheriae strains isolated from all areas in Belarus during a declining period of diphtheria morbidity (1996-2005) was undertaken. Of these, 384 strains were isolated from diphtheria cases, 1968 from tonsillitis patients, 426 from contacts and 735 from healthy carriers. Four hundred and thirty two selected strains were ribotyped. RESULTS: The C diphtheriae gravis biotype, which was prevalent during 1996-2000, was replaced by the mitis biotype during 2001-2005. The distribution of toxigenic C. diphtheriae strains also decreased from 47.1% (1996) to 5.8% (2005). Changes in the distribution of the

Catalyzes the attachment of glutamate to tRNA(Glu) in a two-step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu).

In 2015, the Clinical and Laboratory Standards Institute (CLSI) updated its breakpoints for penicillin susceptibility in Corynebacterium species from <1 mg/L to <0.12 mg/L. We assessed the effect of this change on C. diphtheriae susceptibility reported at an inner city, tertiary care center in Vancouver, British Columbia, Canada, during 2015-2018 and performed whole-genome sequencing to investigate phenotypic and genotypic resistance to penicillin. We identified 44/45 isolates that were intermediately susceptible to penicillin by the 2015 breakpoint, despite meeting previous CLSI criteria for susceptibility. Sequencing did not reveal β-lactam resistance genes. Multilocus sequence typing revealed a notable predominance of sequence type 76. Overall, we saw no evidence of penicillin nonsusceptibility at the phenotypic or genotypic level in C. diphtheriae isolates from our institution. The 2015 CLSI breakpoint change could cause misclassification of penicillin susceptibility in C. diphtheriae

Four subspecies are recognized: C. d. mitis, C. d. intermedius, C. d. gravis, and C. d. belfanti. The four subspecies differ slightly in their colonial morphology and biochemical properties, such as the ability to metabolize certain nutrients, but all may be toxigenic (and therefore cause diphtheria) or not toxigenic. C. diphtheriae produces diphtheria toxin which alters protein function in the host by inactivating the elongation factor EF-2. This causes pharyngitis and pseudomembrane in the throat. The diphtheria toxin gene is encoded by a bacteriophage found in toxigenic strains, integrated into the bacterial chromosome. To accurately identify C. diphtheriae, a Gram stain is performed to show Gram-positive, highly pleomorphic organisms with no particular arrangement. Special stains like Alberts stain and Ponders stain are used to demonstrate the metachromatic granules formed in the polar regions. The granules are called polar granules, Babes Ernst granules, volutin, etc. An enrichment ...

We report an annotated draft genome of the human pathogen Corynebacterium diphtheriae bv. intermedius NCTC 5011. This strain is the first C. diphtheriae bv. intermedius strain to be sequenced, and our results provide a useful comparison to the other primary disease-causing biovars, C. diphtheriae bv. gravis and C. diphtheriae bv. mitis. The sequence has been deposited at DDBJ/EMBL/GenBank with the accession number AJVH01000000.. ...

Novel nontoxigenic Corynebacterium diphtheriae was isolated from a domestic cat with severe otitis.

In this study, different non-toxigenic C. diphtheriae and a toxin-producing strain were characterized in respect to adhesion to and invasion of epithelial cells. All strains were able to attach to host cells and immuno-fluorescence microscopy revealed internalization and growth of C. diphtheriae within epithelial cells. We could show that adhesion and invasion are not strictly coupled, indicating that different proteins and mechanisms play a role in these processes. Despite the fact that the number of internalized bacteria decreased over time for all investigated strains, a considerable number of bacteria survived prolonged internalization for more than 18 h. Furthermore, V-shaped division forms as well as formation of microcolonies were observed by fluorescence microscopy, suggesting that the epithelial cells might support growth of C. diphtheriae.. While proteins responsible for invasion and intracellular persistence are completely unknown for C. diphtheriae, for the sequenced strain NCTC13129 ...

Diphtheria toxin (DT) is produced by toxigenic strains of the human pathogen Corynebacterium diphtheriae as well as zoonotic C. ulcerans and C. pseudotuberculosis. Toxigenic strains may cause severe respiratory diphtheria, myocarditis, neurological damage or cutaneous diphtheria. The DT encoding tox gene is located in a mobile genomic region and tox variability between C. diphtheriae and C. ulcerans has been postulated based on sequences of a few isolates. In contrast, species-specific sequence analysis of the diphtheria toxin repressor gene (dtxR), occurring both in toxigenic and non-toxigenic Corynebacterium species, has not been done yet. We used whole genome sequencing data from 91 toxigenic and 46 non-toxigenic isolates of different pathogenic Corynebacterium species of animal or human origin to elucidate differences in extracted DT, DtxR and tox-surrounding genetic elements by a phylogenetic analysis in a large sample set. Sequences of both DT and DtxR, extracted from whole genome sequencing data,

Previous reports of the excellent correlation between MEE, ribotyping, and epidemiologic data prompted us to use these methods in our study (8, 17; A. De Zoysa, A. Efstratiou, R. C. George, A. McNiff, J. Vuopio-Varkila, I. Mazurova, G. Tseneva, W. Thilo, C. Andronescu, and C. Roure, Prog. Abstr. 2nd Int. Meet. Eur. Lab. Working Group Diphtheria, p. 22, 1995). The inclusion of the Canadian strains has expanded the previously documented ET 215 complex to include 21 ETs and 28 isolates (previously 12 ETs and 15 isolates) (16). Unlike the ET 8 complex, which is associated with the recent epidemic in Russia and the former Soviet Republics (New Independent States) and contains only biotype gravis strains (17), the ET 215 complex contains strains of biotypes gravis, mitis, and belfanti. The existence of toxigenic biotype belfanti strains is unusual because strains of this biotype are generally nontoxigenic (1). Interestingly, isolation of toxigenic strains of biotype belfanti was reported among the ...

For 2017, 39 cases of diphtheria due to toxigenic Corynebacterium diphtheriae or C. ulcerans were reported to ECDC. The highest proportion of C. ulcerans cases was among adults 45 years of age and above, whereas C. diphtheriae cases were more common in younger age groups. Among C. diphtheriae cases, 50% were reported as imported. High vaccination coverage is crucial to prevent diphtheria. ...

Classic diphtheria is characterized by the formation of a pseudomembrane on respiratory mucous membranes. Initial testing includes CBC and a rapid strep test. A diphtheria culture is usually diagnostic if disease symptoms are present.

An 11-year old child presented with a sore throat due to diphtheria, and died in hospital two days later from the disease. Only four cases of diphtheria have been reported in South Africa since 2000, and none since 2005. The clinical presentation, differential diagnosis, diagnosis, and management of diphtheria are discussed. Despite an established immunisation programme, isolated cases of diphtheria still occur in South Africa, and with international travel, should form part of the differential diagnosis of sore throats anywhere, as treatment has to be instituted promptly to ensure a favourable outcome.

During March-June 2015, a cluster of 15 respiratory diphtheria patients with a case-fatality ratio of 27% was reported from KwaZulu-Natal Province in South Africa (11). In 2014, before the outbreak, a KwaZulu-Natal official reported that the province had 96% coverage for the primary series of diphtheria vaccinations and 83% coverage for the 18-month booster (N. McKerrow, KwaZulu-Natal Department of Health, pers. comm., 2015 Jun 8). However, the tetanus-diphtheria booster coverage rates were 54% for 6-year-olds and 20% for 12-year-olds. In response to the outbreak of diphtheria, contact tracing was conducted and postexposure prophylaxis was given to family members and school and clinic contacts (11). Educational leaflets about social mobilization and health promotion activities were distributed in affected communities. The KwaZulu-Natal Department of Health embarked on a catch-up vaccination campaign for schoolgoing children 6-15 years of age in the affected districts. National guidelines for the ...

The essential lysine, Lys179 in SpaD, is in the floor of the groove and is mostly covered by the mobile β1-β2 loop. A similar β1-β2 loop is present in all major pilins for which full-length structures are available, except for Spy0128, which lacks an equivalent YPKN pilin motif. This β1-β2 loop flanks a similar groove in each case, but is usually disordered. In SpaD it is disordered in one molecule and ordered but with high B factors in the other. This flexibility may have a role in pilus polymerization, with the loop preventing unwanted inter-actions by covering the groove and then opening up to allow binding of the sortase-recognition segment of another molecule.. Our results showing a mixture of SpaD species, with the D1 internal isopeptide bond either formed or not formed, indicate that the bond in the N domain may not be fully formed in a SpaD monomer. An energy barrier clearly exists, possibly conformational in nature as shown for RrgB, and this can be overcome in vitro by warming. ...

Cells from your throat, nose, or skin may be collected for this test. Mucus from your throat also may be collected[1][2][3]. Throat cells/mucus: A throat culture is done to collect mucus and cells from the back of your throat. For a throat culture, you will need to open your mouth wide. The person doing the test will use a long, sterile cotton swab to swab the back of your throat, near your tonsils. The swab may be rubbed several times to obtain the sample. Do not close your mouth when the sample is being collected. After the sample has been collected, the swab will be taken out and tested. Nasopharyngeal cells: A nasopharyngeal swab, aspirate, or wash is done to collect cell samples from the upper part of your nose and throat. For a nasopharyngeal swab, you will be asked to tilt your head back. The person doing the test will use a special kind of swab and insert it into one of your nostrils. The swab will be rotated gently and then remain still for a few seconds before it is removed. This is to ...

The phosphoenolpyruvate (PEP)-dependent phosphotransferase system (PTS) is a major mechanism used by bacteria for uptake of carbohydrates, particularly hexoses, hexitols, and disaccharides, where the source of energy is from PEP. The PTS consists of two general components, enzyme I (EI) and histidine phosphocarrier protein (HPr), and of membrane-bound sugar specific permeases (enzymes II). Each enzyme II (EII) complex consists of one or two hydrophobic integral membrane domains (domains C and D) and two hydrophilic domains (domains A and B). EII complexes may exist as distinct proteins or as a single multidomain protein. The PTS catalyzes the uptake of carbohydrates and their conversion into their respective phosphoesters during transport. There are four successive phosphoryl transfers in the PTS. Initial autophosphorylation of EI, using PEP as a substrate, is followed by transfer of the phosphoryl group from EI to HPr. EIIA catalyzes the self-phosphoryl transfer from HPr after which the ...

The citrate cycle (TCA cycle, Krebs cycle) is an important aerobic pathway for the final steps of the oxidation of carbohydrates and fatty acids. The cycle starts with acetyl-CoA, the activated form of acetate, derived from glycolysis and pyruvate oxidation for carbohydrates and from beta oxidation of fatty acids. The two-carbon acetyl group in acetyl-CoA is transferred to the four-carbon compound of oxaloacetate to form the six-carbon compound of citrate. In a series of reactions two carbons in citrate are oxidized to CO2 and the reaction pathway supplies NADH for use in the oxidative phosphorylation and other metabolic processes. The pathway also supplies important precursor metabolites including 2-oxoglutarate. At the end of the cycle the remaining four-carbon part is transformed back to oxaloacetate. According to the genome sequence data, many organisms seem to lack genes for the full cycle [MD:M00009], but contain genes for specific segments [MD:M00010 M00011 ...

Diphtheria is caused by the bacteria Corynebacterium diphtheriae and mainly affects the nose and throat. The bacteria spreads through airborne droplets and shared personal items. C. diphtheriae creates a toxin in the body that produces a thick, gray or black coating in the nose, throat or airway, which can also affect the heart and nervous system. Even with proper antibiotic treatment, diphtheria kills about 10 percent of the people who contract it. The first diphtheria vaccine was unveiled in 1913, and although vaccination has made a major dent in mortality rates, the disease still exists in developing countries and other areas where people are not regularly vaccinated. The World Health Organization (WHO) estimates that worldwide there are about 5,000 deaths from diphtheria annually, but the disease is quite rare in the United States, with fewer than five cases reported each year.. ...

Toxin-producing Corynebacterium diphtheriae was identified in cutaneous wounds from four U.S. residents after return from international travel. Public health response for toxin-producing diphtheria includes treating patients, providing chemoprophylaxis to close contacts, testing patients and close contacts for C. diphtheriae carriage, and providing diphtheria toxoid-containing vaccine to incompletely immunized patients and close contacts.

The infectious disease hospital in Batumi, with the assistance of MSF, treated over 300 cases of diphtheria from 1993 to 1995 and recorded a case-fatality rate of about 8%.. Diphtheria is most common in areas where there is overcrowding, poor hygiene and low immunity owing to waning immunization in adults and gaps in universal vaccination coverage in children.1 Corynebacterium diphtheriae is transmitted directly or indirectly from a case or carrier through respiratory droplets or skin infections involving C. diphtheriae.2 Patients typically present, after a brief incubation period of 1 to 7 days, with a mild sore throat and low-grade fever. The characteristic thick, adherent, green-black pharyngeal or laryngeal membrane spreads rapidly, and the microorganisms invade the neck tissues, producing marked swelling and a bullneck appearance.3 In laryngeal diphtheria, primarily seen in children, the membrane may spread over the airway and result in severe respiratory obstruction. In addition, an ...

The symptoms of diphtheria are caused by toxins produced by the diphtheria bacillus, Corynebacterium diphtheriae (from the Greek for rubber membrane). In fact, toxin production is related to infections of the bacillus itself with a particular bacteria virus called a phage (from bacteriophage, a virus that infects bacteria). The intoxication destroys healthy tissue in the upper area of the throat around the tonsils or in open wounds in the skin. Fluid from the dying cells then coagulates to form the telltale gray or grayish green membrane. Inside the membrane, the bacteria produce an exotoxin, which is a poisonous secretion that causes the life-threatening symptoms of diphtheria. The exotoxin is carried throughout the body in the bloodstream, destroying healthy tissue in other parts of the body. The most serious complications caused by the exotoxin are inflammations of the heart muscle (myocarditis) and damage to the nervous system. The risk of serious complications is increased as the time ...

Diphtheria is a dangerous respiratory disease is caused by a potent toxin produced by certain strains of the bacterium Corynebacterium diphtheriae. Diphtheria is extremely contagious through coughing or sneezing. Risk factors include crowding, poor hygiene, and lack of immunization.. Symptoms usually appear within a week of infection. This infection is characterized by a sore throat, coughing and fever very similar to many common diseases like strep throat. Additional symptoms may be bloody, watery discharge from the nose and rapid breathing. However, a presumptive diagnosis can be made by observing a characteristic thick grayish patch (membrane) found in the throat. In more severe cases, neck swelling and airway obstruction may be observed. In the tropics, cutaneous and wound diphtheria is much more common and can be a source of transmission..

Löfflers medium is a special substance used to grow diphtheria bacilli to confirm the diagnosis. In 1887, Friedrich Loeffler devised a culture medium containing horse serum, meat infusion, and dextrose for use in the cultivation of corynebacteria and for differentiating them from other organisms. Perry and Petran suggested modification of the original formulation. Buck, in 1949, described a modified Loefflers medium for cultivating Corynebacterium diphtheriae. This medium has a variety of uses in microbiological investigations. The current formulation incorporated these later modifications: The primary value of Loeffler medium is in the growth and morphological characterization of members of the genus Corynebacterium. This formulation enhances the formation of metachromatic granules within the cells of the organisms. Due to its serum content, Loeffler medium can be used for the determination of proteolytic activities of microorganisms. The gray-white surface of the medium provides an ...

Diphtheria is caused by corynebacterium diphtheriae. Diphtheria may lead to neurological disturbance and myocardium disturbance due to the effects of toxin. The toxin is originated from the pseudomembrane consists of fibrin, bacteria and necrotic cells.

Diphtheria is disease that affects primarily the upper respiratory system and is caused by the bacterium Corynebacterium diphtheriae. The bacterium is most commonly spread through person-to-person contact. Diphtheria can be prevented by a vaccine. Canada has included diphtheria in its infant immunization schedule since the 1930s. The success of this program led to a dramatic decline in the number of cases, with very few occurring in Canada since the early 1950s. The National Advisory Committee on Immunization (NACI) recommends immunization against diphtheria ...

Background Diphtheria is an acute infectious disease caused by Corynebacterium diphtheriae affects primarily the upper respiratory tract with the formation of greyish white pseudomembrane. Diphtheria can lead to a characteristic swollen neck and throat, or Bull-neck. The swollen throat is often accompanied by a serious respiratory condition. Delay in treatment increases morbidity and mortality. Management consists of the use of specific antitoxins and elimination of the causative organism. Objective We report a case of tonsilopharyngeal and laryngeal diphtheria accompanied by bull neck in an 7 year 1 month old boy Case A 7-year 1 month old boy was referred to the Dr. Wahidin Sudirohusodo Hospital with a low-grade fever, sore throat due to painfull swallowing for 5 days. On examining the patient, we found his to be fever, tachypnea and in severe stridor. An examination of the oral cavity he had bilateral grade III tonsils covered by a dirty greyish white membrane. Removal of this membrane ...

This situation is highlighted in a case described in the January 13, 2017 issue of Science magazine. A three-year-old girl was admitted to a hospital in Antwerp, Belgium in March of 2016. She was diagnosed with having severe tonsillitis, but physicians noted an unusual thick layer of grey dead cells covering her throat. It was a hallmark symptom for diphtheria known as a pseudomembrane. Diphtheria is caused by the bacterium Corynebacterium diphtheriae. The initial symptoms present as a sore throat and fever, and can progress to blocking the lungs if left untreated. The exotoxin secreted by the bacteria can also cause damage to the heart and liver. ...

We have previously described sigma A and sigma B and their structural genes, mysA and mysB, respectively, in Mycobacterium smegmatis. We have now sequenced the corresponding regions in the M. tuberculosis and M. leprae chromosomes, and have found the two homologous genes. The chromosomal linkage and the deduced amino acid (aa) sequences of the two genes show very high similarity in the three species of mycobacteria. We also report the finding of two other open reading frames (ORF) in these clusters. orfX, which has an unknown function, is located between mysA and mysB. The other ORF, located downstream from mysB, encodes a homolog of DtxR, the iron regulatory protein from Corynebacterium diphtheriae (Cd).

Antisera prepared from hyperimmune horse blood are still used as drugs against diphtheria toxin (DT) in emergency situations. Since equine antisera could induce serious side effects such as serum sickness, there is a strong need to develop a human monoclonal antibody (Ab) against DT. DT excreted by Corynebacterium diphtheriae has been well characterized (12). It is a single polypeptide chain (Mr, 58,000) composed of two structurally distinct regions with three functional domains and contains a protease-sensitive site. The nicked toxin produced upon limited proteolysis consists of two polypeptides that are held together by a disulfide bond. The NH2-terminal region, fragment A, catalyzes the transfer of the ADP-ribose moiety from NAD to elongation factor 2 and thus blocks protein synthesis (4). The COOH-terminal region, fragment B, binds to a specific receptor on the cell surface and mediates transfer of fragment A to the cytoplasm (6, 11, 14). DT is lethal for susceptible animals, including ...

H. Fiss, Y. Yu, and W. R. Jacobs, Jr., Mol. Microbiol. 14:557-569, 1994). We investigated the regulation of fxbA by the mycobacterial IdeR, a homolog of the Corynebacterium diphtheriae iron regulator DtxR (M.P. Schmitt, M. Predich, L. Doukhan, I. Smith, and R. K. Holmes, Infect. Immun. 63:4284- 4289, 1995). Gel mobility shift experiments showed that IdeR binds to the fxbA regulatory region in ...

Corynebacterium pseudotuberculosis is a Gram-positive bacterium that belongs to the class Actinobacteria. This bacterium is a facultative intracellular pathogen that causes the disease caseous lymphadenitis (CL) in sheep and goats. During the process of infection by these bacteria are contained cells of the innate immune response, among which the main effectors defensives cells are neutrophils and macrophages. This work has been proposed with the aim of assessing the response of murine bone marrow monocyte-derived macrophages in in vitro infection with the CP13 strain of C. pseudotuberculosis - a knockout mutant for a gene related to the transportation of iron in Corynebacterium diphtheriae that generated good levels of protection against subsequent infections C. pseudotuberculosis - and observe the response profile generated by these cultures. This type of characterization allows the inference of the involvement of innate immune response against infections caused by this bacterium. So far, it ...

Cephalexin is attributed as antibiotic of cephalosporins group which acts against bacteria preventing formation of their cell walls. It is enough resistant to penicillinases of gram positive microorganisms but can be destroyed by beta-lactamases of gram negative ones. It shows broad spectrum activity against gram positive microorganisms such as Staphylococcus, Staphylococcus epidermidis; Streptococcus, Corynebacterium diphtheriae, Clostridium, Actinomyces israelii, Bacillus anthracis, gram negative microorganisms like Escherichia coli, Klebsiella, Proteus mirabilis, Neisseria gonorrhoeae, Neisseria meningitidis, Shigella, Salmonella. Common infections that are treated with Cephalexin include infections of the middle ear, tonsils, throat, larynx (laryngitis), bronchi (bronchitis) and pneumonia as well as in urinary tract, skin, and bones ...

C diphtheriae is comprised of irregularly staining gram-positive, nonspore-forming, unencapsulated slender rods. Branching and clubbed ends result in a cuneiform appearance. Metachromatic granules are common. There are three phenotypes of the organism: gravis, intermedius, and mitis, differentiated by colony morphology, growth characteristics, and biochemical reactions. All are capable of elaborating a cytotoxic exotoxin, which interferes with protein synthesis in host cells. The ability of a strain of C diphtheriae to produce toxin is conferred by a lysogenic bacteriophage that carries the gene for toxin production. The clinical signs and symptoms depend on the primary site of infection. Toxins produced by the three types are qualitatively similar, but the gravis and intermedius strains produce more toxin than does the mitis strain. ...
