Absztrakt:

A tracheobronchialis sérülések ritkák, de életveszélyes állapotot jelenthetnek. Leggyakoribb okaik a nyaki vagy mellkasi, nagy energiájú tompa trauma, a nehéz intubálás vagy az intratrachealis tubus és gyomorszonda együttes viselése. A korai diagnózis és a megfelelő kezelés életmentő lehet, e sérülések felismerése azonban az atípusos tünetek és a súlyos társsérülések miatt gyakran elhúzódik. Típusos esetekben a fizikális vizsgálat során progresszív, kiterjedt subcutan emphysema hívhatja fel rájuk a figyelmet. További nehézséget jelent, hogy a radiológiai jelek nem elég specifikusak, a komputertomográfiás felvételeken pedig a leggyakrabban csupán subcutan emphysema, pneumomediastinum vagy esetenként pneumothorax látható. Cikkünkben három eset kapcsán mutatjuk be a tracheobronchialis sérüléseket – egy baleseti, egy nehéz intubációs légúti sérülés, illetve egy tracheooesophagealis fistula kialakulása során. Az endotrachealis tubus ballonja a tracheafal rupturája mentén mindegyik esetben túlfújhatóvá vált, így a légút falán kívülre terjedt – ez a képalkotó vizsgálatokon láthatóvá is vált. Ez egy ritka, de direkt és egyértelmű jele a légúti sérüléseknek, mely alapján a trachea teljes falvastagságának szakadására lehet számítani. Cikkünkben a túlfújt ballon diagnosztikus jelentőségére szeretnénk rávilágítani. Orv Hetil. 2020; 161(25): 1063–1068.

Absztrakt:

Az új koronavírus által okozott COVID–19 tüdőgyulladással, heveny légzési elégtelenséggel vagy akár szepszissel járhat. Azoknál a betegeknél alakul ki gyakrabban súlyos állapot, akik valamilyen krónikus alapbetegségben szenvednek. Cikkünk célja felhívni a figyelmet azon esetekre, amelyek elemzése segíthet a COVID–19-tüdőgyulladás lefolyását és mortalitását befolyásoló faktorok felderítésében. Idős betegünk anamnézisében rectumexstirpatio szerepel intraoperatív reanimációval. 2020 januárjában egy időben igazolódott colon ascendens adenocarcinoma, illetve pulmonalis embolia. Hathetes, terápiás dózisú, kis molekulatömegű heparinos (LMWH-) kezelést követően elvégeztük a daganatos szegment reszekcióját. Intraoperatív sikeres reanimáció történt. A műtét után 15 nappal endoszkóposan nem csillapítható, spriccelő anastomosisvérzés miatt akut jobb oldali hemicolectomiát végeztünk. Ezt követően a lázas állapot hátterében COVID–19 igazolódott; tüneti kezelés mellett a beteg láztalanná vált. A továbbiakban anastomosisinsufficientia alakult ki, mely konzervatív terápia alkalmazása mellett szintén gyógyult. Három negatív SARS-CoV-2-vizsgálat után betegünket emittáltuk. Figyelemre méltó, hogy betegünk preoperatív tartós LMWH-kezelésben részesült; az aktív vérzés miatt gyógyszereléséből az angiotenzinkonvertálóenzim (ACE)-gátló elhagyásra került, majd ezt követően SARS-CoV-infekció alakult ki, de multimorbiditása ellenére is meggyógyult. A colorectalis carcinomák a lassan növekvő malignomák közé tartoznak ugyan, ám fontosnak tartjuk ezek megfelelő időben történő kezelését, még súlyos járványügyi helyzetben is. Nagy kihívás elé állít minden orvost a pandémia alatt a betegek megfelelő ellátása, de – mint esetünk is példázza – sikeres lehet a multimorbid betegek sebészeti ellátása is. További következtetésünk, hogy érdemes lenne vizsgálni a társbetegségek kezelésére használt gyógyszerek és a SARS-CoV-2 közötti azon interakciókat, amelyek befolyásolhatják a COVID–19-tüdőgyulladás kimenetelét.

Abstract

The aim of this study was to estimate the prevalence of antimicrobial resistance (AMR) in Escherichia coli from a dog population in Spain and assess specific virulence factors. Susceptibility to 22 antimicrobials was tested along with the production of extended-spectrum β-lactamases (ESBLs) and AmpC in faecal isolates from 100 dogs. Virulence-related genes associated with attaching and effacing E. coli (eae, Stx1, Stx2) and extraintestinal pathogenic E. coli – ExPEC – (papC, hlyA and cnf1) were detected by PCR. At least one kind of AMR was observed in 73% of the isolates. The highest prevalences corresponded to penicillin (45%), aminoglycoside (40%) and non-extended spectrum cephalosporin (39%) classes. Multidrug resistance (MDR) was observed in 53.4% of the resistant isolates. No resistance to colistin was found. Production of ESBL/AmpC enzymes was detected in 5% of E. coli. Shiga toxin-producing E. coli were not observed, enteropathogenic E. coli were identified in only 12% of them, and ExPEC were found in 25%. Dog faeces can be a source of E. coli strains potentially presenting a threat to humans through their virulence factors or AMR. The non-hygienic keeping of animals may increase the risk of colonisation of such pathogens in humans.

Abstract

This paper reports the detection of the myxozoan species Myxobolus elegans Kashkovsky 1966 in common dace (Leuciscus leuciscus) that has not been previously listed as its host. The problem of differentiation of phenotypically similar Myxobolus species is addressed. During parasitological survey of common dace from the desalinated part of the Gulf of Finland at the city of Sestroretsk, Russia, numerous oval-shaped plasmodia, 0.2–0.4 mm in size, filled with Myxobolus spores were found on the gills. Pear-shaped myxospores were 15.4 (14.8–16.0) × 10.2 (9.6–10.9) µm in size with a rib on each valve. On the basis of spore morphology, the species appeared to be similar to M. elegans and Myxobolus hungaricus Jaczó, 1940. In order to identify the species, molecular genetic analysis was performed, and the species was identified on the basis of morphological characteristics and 18S rDNA data. The results obtained indicate that the Myxobolus species observed on the gills of dace is M. elegans. Thus, common dace is another valid host of M. elegans besides the type host, ide (Leuciscus idus).

Abstract

The aim of the study was to assess the incidence, resistance, virulence, and genotypic characteristics of Staphylococcus spp. residing in the gastrointestinal tract of dogs and cats, as a group of animals causing potential contamination of the urban space. A high percentage of strains resistant to penicillin (58%), oxacillin (9%) and tetracycline (60%) were found. All isolates resistant to penicillin, kanamycin, or chloramphenicol carried genes responsible for individual resistance (blaZ, aph(3′)-IIIa, and cat (pC194)/cat (pC223), respectively. The mecA gene was detected in 45% of the oxacillin-resistant Staphylococcus pseudintermedius strains. The amplification of DNA fragments surrounding rare restriction sites analysis demonstrated high heterogeneity of genotypic profiles correlating with phenotypic resistance profiles. Multilocus sequence typing analysis classified the methicillin-resistant S. pseudintermedius strains as ST71, ST890, and the totally new ST1047. The presence of a high level of resistance among Staphylococcus strains may suggest a potential risk of transfer of these bacteria between companion animals and humans.

Abstract

Two adult barbels (Barbus barbus) with visible skin tumours were subjected to histopathological and molecular examinations. The fish were caught in the River Danube near Budapest. Papillomas were found around their oral cavity, at the operculum and at the pectoral fins, while epidermal hyperplasias were seen on the body surface. Cyprinid herpesvirus 1 (CyHV-1) was detected in the kidney of the specimens by polymerase chain reaction (PCR), and barbel circovirus 1 (BaCV1) was found in all internal organs and in the tissues of the tumours. The whole genome of BaCV1 and three conserved genes from the genome of CyHV-1 were sequenced. Previously, BaCV1 had been reported only once from a mass mortality event among barbel fry. The whole genome sequence of our circovirus shared 99.9% nucleotide identity with that of the formerly reported BaCV1. CyHV-1 is known to infect common carp and coloured carp (Cyprinus carpio), and has been assumed to infect other cyprinid fish species as well. We found the nucleotide sequences of the genes of CyHV-1 to be identical in 98.7% to those of the previous isolates from carp. To the best of our knowledge, this is the first molecular confirmation of the presence of CyHV-1 DNA in cyprinid fish species other than carp.

Abstract

Squamous cell carcinoma (SCC) is the most common malignant neoplasm of the skin in cats. Tumour angiogenesis is the pivotal event for tumour progression and metastasis. We assessed protein and gene expression of angiogenic growth factors including bFGF, VEGF-C, TGF-β, PDGF-A, PDGF-C and PDGFR-α that possibly contribute to the angiogenic phenotype of feline SCC (FSCC) and could, therefore, be a good target in the treatment of SCC. In the present study, a total of 27 FSCC cases were investigated. Tumour cases were histopathologically classified as well differentiated (10/27), moderately differentiated (5/27), and poorly differentiated (12/27). The expression levels of the growth factors were detected using immunohistochemistry and assessed semi-quantitatively. Growth factor expression levels were evaluated at different locations: in the oral region, in areas exposed to solar UV radiation including the ears, eyelids and nasal planum, and other miscellaneous locations. Our findings have revealed that FSCC arising from different anatomical sites of the body and showing differences in aggressiveness, metastasis, and prognosis may be angiogenesis dependent, and angiogenic key regulators could play a role in the development of FSCC.

Abstract

Recently, the occurrence of Ixodes (Pholeoixodes) kaiseri has been reported for the first time in several European countries, but data on the molecular analysis of this hard tick species are still lacking. Therefore, in this study DNA extracts of 28 I. kaiseri (collected from dogs and red foxes in Germany, Hungary and Romania) were screened with reverse line blot hybridisation (RLB), PCR and sequencing for the presence of 43 tick-borne pathogens or other members of their families from the categories of Anaplasmataceae, piroplasms, rickettsiae and borreliae. Rickettsia helvetica DNA was detected in one I. kaiseri female (from a red fox, Romania), for the first time in this tick species. Six ticks (from red foxes, Romania) contained the DNA of Babesia vulpes, also for the first time in the case of I. kaiseri. Molecular evidence of R. helvetica and B. vulpes in engorged I. kaiseri does not prove that this tick species is a vector of the above two pathogens, because they might have been taken up by the ticks from the blood of foxes. In addition, one I. kaiseri female (from a dog, Hungary) harboured Babesia sp. badger type-B, identified for the first time in Hungary and Central Europe (i.e. it has been reported previously from Western Europe and China). The latter finding can be explained by either the susceptibility of dogs to Babesia sp. badger type-B, or by transstadial survival of this piroplasm in I. kaiseri.

Abstract

This paper describes the first documented outbreak of haemorrhagic septicaemia (HS) caused by Pasteurella multocida type B in cattle in Spain. This acute, highly fatal septicaemia causes major economic losses in cattle and buffaloes in many areas of Asia and Africa. In other species and in European countries it is an infrequently reported disease. Acute septicaemic pasteurellosis occurred in a free-range farm of 150 cattle and 70 beef calves in Southern Spain. Twenty-one calves and one cow were affected, of which three calves and the adult cow died. Postmortem examination revealed characteristic oedema in the ventral area of the neck and the brisket region, and widespread haemorrhages in all organs. Pure cultures of P. multocida were obtained from all tissues and organs studied. The aetiological agent was further confirmed by molecular and biochemical analysis as P. multocida capsular type B, biovar 3. Although the source of infection could not be determined, wildlife may play an important role. The use of tulathromycin in the initial stage of the disease might be related to the low morbidity and mortality of this outbreak. After using an autogenous vaccine no more cases of HS were observed.

Abstract

In view of the enormous variability of dog breeds, breed-specific reference intervals (RIs) are recommended for use in veterinary clinical decision-making. The aim of this study was to determine whether RIs of the general canine population may be applied to the Italian Greyhound (Piccoli Levrieri Italiani or PLI), and to generate breed-specific RIs, where appropriate. Sixty-three privately owned clinically healthy fasted dogs were examined. Routine haematology and biochemistry were performed on 58 enrolled patients using the ADVIA 120 haematology analyzer and the Cobas Mira system, respectively. Changes in haematological and biochemical parameters depending on sex, age and attitude (resting vs. running dogs) were investigated. The results of PLI were compared with the RIs of the general canine population. In those cases in which these RIs were not validated, new RIs were generated according to the guidelines of the American Society of Veterinary Clinical Pathology. Pre-existing RIs were considered valid based on the recommendations by the Clinical & Laboratory Standards Institute (CLSI). RIs were higher for mean corpuscular haemoglobin (MCH), mean cell haemoglobin concentration (MCHC), cell haemoglobin concentration mean (CHCM) and lower for large unstained cells (LUC). A wider discrepancy between pre-existing and newly established RIs was found for some ADVIA parameters regarding red blood cell (RBC) or reticulocyte morphology. For total protein and cholesterol the new RIs were wider than the pre-existing ones, while albumin, calcium and iron were higher. This study suggests that most of the RIs published in veterinary textbooks cannot be validated for PLIs.
