Istraživanje prisutnosti proizvodnje sluzi, VanA gena i gena za rezistenciju na antiseptike u stafilokoka izoliranih iz goveđeg mastitisa u Alžiru

Staphylococcus strains are frequently associated with clinical and subclinical bovine intra-mammary infection. The virulence factors of staphylococcus have not been widely studied in Algeria. The objective of this study was to determine the frequency of slime production, VanA gene and antiseptic resistance genes in staphylococci strains isolated from bovine mastitis in Algeria. The study examined 35 Staphylococci strains obtained from the inflammatory secretion of mammary glands of cows with mastitis. Slime production was determined by detecting the icaA and icaD genes using the polymerase chain reaction (PCR) method and Congo red agar (CRA) method. The presence of qacAB and qac C antiseptic resistance genes and the VanA resistance gene in these isolates was investigated by PCR. The results of the current study revealed that of the 35 Staphylococci isolates, 42.85% (15/35) and 17.14% (6/35) of the isolates harboured the slime production gene by analysing icaA and icaD genes, respectively and 71.42% (25/35) by the CRA method. However, VanA and antiseptic resistance genes (qacAB and qac C) were not detected in any of the isolates. Therefore, the majority of Staphylococcus strains were capable of producing slime, and the CRA detection rate was higher than the PCR method for the biofilm-producing capacity of Staphylococcus strains. Thus, the presence of the ica genes in Staphylococcus strains confirms its role as a virulence factor in the pathogenesis of bovine mastitis.Sojevi stafilokoka često su povezani s kliničkim i supkliničkim intramamarnim infekcijama goveda. Faktori virulencije stafilokoka nisu dobro istraženi u Alžiru. Cilj ove studije bio je odrediti učestalost proizvodnje sluzi, VanA gena i gena za rezistenciju na antiseptike u sojevima stafilokoka izoliranih iz goveđeg mastitisa u Alžiru. Istraživanja su obuhvatila 35 soja stafilokoka dobivenih iz upalnog sekreta mliječnih žlijezda krava s mastitisom. Proizvodnja sluzi ustvrđena je metodom lančane reakcije polimeraze (PCR) istraživanjem ıcaA i ıcaD gena, odnosno metodom s Kongo crvenim agarom (CRA). Prisutnost qacAB i qac C gena za rezistenciju na antiseptike i VanA gena za rezistenciju u tim izolatima ispitana je pomoću PCR. Rezultati ove studije otkrili su da je od 35 izolata stafilokoka, 42,85 % (15/35) i 17,4 % (6/35) sadržavalo gen za proizvodnju sluzi putem analize ıcaA i ıcaD gena, odnosno 71,42 % (25/35) CRA metodom. Međutim, VanA i geni za rezistenciju na antiseptike (qacAB i qac C) nisu detektirani niti u jednom izolatu. Stoga se iz podataka može zaključiti da je većina sojeva stafilokoka bila sposobna proizvoditi sluz, a detekcija CRA metodom je bila više od PCR metode za kapacitet proizvodnje biofilma sojeva stafilokoka. Stoga, prisutnost ica u sojevima stafilokoka potvrđuje njegovu ulogu kao faktora virulentnosti u patogenezi goveđeg mastitisa

Pulmonary Rehabilitation Using Modified Threshold Inspiratory Muscle Trainer (IMT) in Patients with Tetraplegia

It is aimed to present the usefulness of inspiratory muscle trainer (IMT) in treatment of a 20-year-old male patient with diaphragmatic paralysis and tetraplegia due to spinal cord injury (SCI), and supporting effect of IMT in recovering from respiratory failure by rendering his diaphragm functions. The treatment was applied through the tracheostomy cannula by a modified IMT device. After applying IMT for three weeks, it was observed that the diaphragm recovered its functions in electromyography (EMG) test. As a result, in this study, we present a case where a patient could live without any respiratory device for the rest of his life with the help of modified IMT

New Mediterranean biodiversity records (October 2015)

The Collective Article “New Mediterranean Biodiversity Records” of the Mediterranean Marine Science journal offers the means to publish biodiversity records in the Mediterranean Sea. The current article has adopted a country-based classification and the countries are listed according to their geographic position, from west to east. New biodiversity data are reported for 7 different countries, although one species reported from Malta is new for the entire Mediterranean basin, and is presumably also present in Israel and Lebanon (see below, under Malta). Italy: the rare native fish Gobius kolombatovici is first reported from the Ionian Sea, whilst the alien jellyfish Rhopilema nomadica and the alien fish Oplegnathus fasciatus are first reported from the entire country. The presence of O. fasciatus from Trieste is concomitantly the first for the entire Adriatic Sea. Finally, the alien bivalve Arcuatula senhousia is reported for the first time from Campania (Tyrrhenian Sea). Tunisia: a bloom of the alien crab ortunus segnis is first reported from the Gulf of Gabes, where it was considered as casual. Malta: the alien flatworm Maritigrella fuscopunctata is recorded in the Mediterranean Sea for the first time, on the basis of 25 specimens. At the same time, web searches include possible unpublished records from Israel and Lebanon. The alien crab P. segnis, already mentioned above, is first formally reported from Malta based on specimens collected in 1972. Concomitantly, the presence of Callinectes sapidus in Maltese waters is excluded since based on misidentifications. Greece: the Atlantic northern brown shrimp Penaeus atzecus, previously known from the Ionian Sea from sporadic records only, is now well established in Greek and international Ionian waters. The alien sea urchin Diadema setosum is reported for the second time from Greece, and its first record from the country is backdated to 2010 in Rhodes Island. The alien lionfish Pterois miles is first reported from Greece and concomitantly from the entire Aegean Sea. Turkey: the alien rhodophyte Antithamnion hubbsii is first reported from Turkey and the entire eastern Mediterranean. New distribution data are also provided for the native fishes Alectis alexandrina and Heptranchias perlo. In particular, the former record consists of a juvenile measuring 21.38 mm total length, whilst the latter by a mature male. Cyprus: the rare native cephalopod Macrotritopus defilippi, and the alien crab Atergatis roseus, sea slug Plocamopherus ocellatus and fish Cheilodipterus novemstriatus are first recorded from the entire country. Lebanon: the alien crabs Actaea savignii and Matuta victor, as well as the alien fish Synanceia verrucosa, are first recorded from the entire country. In addition, the first Mediterranean record of A. savignii is backdated to 2006, whilst the high number of M. victor specimens observed in Lebanon suggest its establishment in the Basin. The Atlantic fishes Paranthias furcifer and Seriola fasciata, and the circumtropical Rachycentron canadum, are also first reported from the country. The P. furcifer record backdates its presence in the Mediterranean to 2007, whilst S. fasciata records backdate its presence in the eastern Mediterranean to 2005. Finally, two of these latter species have been recently ascribed to alien species, but all three species may fit the cryptogenic category, if not a new one, better.peer-reviewe

Bovine herpesvirus-1 (BHV-1), bovine leukemia virus (BLV) and bovine viral diarrhea virus (BVDV) infections in Algerian dromedary camels (Camelus dromaderius)

International audienceThis study was performed to investigate the presence of bovine herpesvirus-1 (BHV-1), bovine leukemia virus (BLV) and bovine viral diarrhea virus (BVDV) infections in dromedary camels (Camelus dromaderius) kept in mixed herds with sheep and goats in Algeria, since the prevalence of BHV-1, BVDV, and BLV infections among dromedary camels in Algeria is unknown. Totally, 111 camel sera were collected from two provinces (Laghouat and Ghardaia) in Algeria. The sera were analyzed for BHV-1 specific antibodies, BVDV specific antibodies and BVDV antigen using the ELISA, and BLV nucleic acid using PCR. The seropositivity rate was 9.0% for BVDV-specific antibody, although 41.4% of camels tested were positive for BVDV antigen. Moreover, there was no evidence of BHV-1 and BLV infections. The results indicated that camels might represent an important source for BVDV infection in all ruminants, including cattle, sheep, and goats bred in mixed herds in Algeria, since they had a higher BVDV prevalence rates. Therefore, the prevention and control measures for BVDV infection should put in place in camel populations to limit the spread of BVDV infection to ruminant populations in Algeria

Antimicrobial Susceptibility, Presence of Resistance Genes and Biofilm Formation in Coagulase Negative Staphlococci Isolated from Subclinical Sheep Mastitis

In this study, coagulase negative staphylococci (CoNS) (n = 70) isolated from subclinical sheep mastitis were screened for minimum inhibitory concentration (MIC) to antimicrobials used commonly in veterinary field in Turkey. In addition, plasmid profiling and biofilm production of CoNS isolates was investigated. All isolates were found to be susceptible to amoxycillin-clavulanic acid, cephalothin, gentamicin, enrofloxacin and oxacillin. The highest resistance was observed in 42.9% (n = 30) of the isolates against the beta-lactam antibiotics, penicillin and ampicillin. All beta-lactam resistant isolates produced beta-lactamase and carried blaZ. Tetracycline resistance was observed in 11.4% (n = 8) of the isolates, either alone or in combination with beta-lactams and macrolides. Of the tetracycline resistant 8 isolates, 5 carried the tetK gene, one carried the tetM and 2 isolates carried both genes together. Erythromycin resistance was observed in 5.7% of the isolates; msrA was detected alone (one isolate) or in combination with mphC (one isolate) and ermC (one isolate). ermA was observed only in one isolate. Most of the strains showed only a single plasmid band in size of 19.3 kb, but some had 2 to 3 plasmids ranging from >19.3 kb to 0.9 kb. Out of 70 CoNS isolates, 28 (40%) were identified as biofilm producer by Congo red agar (CRA) method, and 30 (42.9%) were positive for both icaA and icaD genes, which are known to be responsible for biofilm formation in CoNS

PCR assay with host specific internal control forStaphylococcus aureus from bovine milk samples

Staphylococcus aureus is considered as one of the most important and common pathogens of bovine mastitis. Polymerase Chain Reaction is frequently proposed in the diagnosis of S. aureus directly from milk samples instead of classical culture. However, false-negative results may occur in the polymerase chain reaction analysis performed directly from clinical material. For the purpose of disclosing the false negative results, the use of internal amplification controls can be beneficial. Therefore, in this study a new polymerase chain reaction technique with host specific internal amplification control was developed by optimizing S. aureus-specific primers in combination with bovine specific primers. The effectiveness of the developed technique in this study was attempted in milk samples from bovine subclinical mastitis. This technique has the potential to detect S. aureus from bovine milk samples or dairy products
