Aims: We determined the association between short-term neonatal morbidities, such as bronchopulmonary dysplasia (BPD) and intraventricular hemorrhage (IVH), Ureaplasma spp. in amniotic fluid, placental mem-brane of preterm infants.
Contamination of semen with bacteria arises during collection and handling. This bacterial contamination is typically controlled by adding antibiotics to extenders but intensive usage can lead the development resistance may be detrimental sperm quality. The objective this study was determine effects in a extender on quality investigate removal modified Single Layer Centrifugation (MSLC) through colloid. Semen collected from six adult pony stallions (three ejaculates per male). Aliquots...
Generally regarded as extracellular pathogens, molecular mechanisms of mycoplasma persistence, chronicity and disease spread are largely unknown. Mycoplasma agalactiae, an economically important pathogen small ruminants, causes chronic infections that difficult to eradicate. Animals continue shed the agent for several months even years after initial infection, in spite long antibiotic treatment. However, little is known about strategies M. agalactiae employs survive within immunocompetent...
The aim of this study was to detect the prevalence methicillin-resistant Staphylococcus sp. (MRS) in populations companion animals that either have previously been exposed or not antibiotic therapy veterinary facilities, and if owners' healthcare profession had an influence on colonization with MRS. In addition, antimicrobial resistance pheno- genotype were investigated risks for MRS assessed. During study, 347 nasal swabs (dogs n = 152; cats 107; rabbits 88) presence aureus (MRSA). 131 79;...
The objective of the present study was to examine diversity Staphylococcus aureus from mastitis milk samples cows in Rwanda.
Mycoplasma bovis is associated with pneumonia in calves characterized by the development of chronic caseonecrotic lesions agent persisting within lesion. The purposes this study were to characterize morphology lung lesions, examine presence M. variable surface protein (Vsp) antigens and local immune responses after infection strain 1067.Lung tissue samples from eight euthanased three weeks experimental examined bacteriology pathology. Lung evaluated immunohistochemical (IHC) staining for...
The consensus of the members International Committee on Systematics Prokaryotes' Subcommittee taxonomy Mollicutes is that recently proposed sweeping changes to nomenclature Mycoplasmatales , specifically involving introduction names Malacoplasma gen. nov., Mesomycoplasma Metamycoplasma Metamycoplasmataceae fam. Mycoplasmoidaceae Mycoplasmoidales ord. Mycoplasmoides Mycoplasmopsis and all species or subspecies comb. nov. placed therein, should be rejected because they violate one more...
Background Brown rats ( Rattus norvegicus ) are an important wildlife species in cities, where they live close proximity to humans. However, few studies have investigated their role as reservoir of antimicrobial-resistant bacteria. Aim We intended determine whether urban at two highly frequented sites Vienna, Austria, carry extended-spectrum β-lactamase-producing Enterobacteriaceae , fluoroquinolone-resistant and meticillin-resistant (MR) Staphylococcus spp. (MRS). Methods surveyed the...
Between 2001 and 2004, 14 Austrian free-ranging red deer (Cervus elaphus hippelaphus) infected by Mycobacterium avium species were observed. Eight of the cases from different geographical regions, six originated same hunting area. The affected animals had signs diarrhea, severe weight loss, emaciation. On post-mortem examination, lymphadenitis associated with grossly enlarged mesenteric lymph nodes as well multiple caseous or purulent nodular lesions in thickened wall intestines present all...
Mycoplasma agalactiae is the main cause of contagious agalactia, a serious disease sheep and goats, which has major clinical economic impacts. We have developed multilocus sequence typing (MLST) scheme using sequenced genomes M. strains PG2 5632. An MLST based on genes gltX, metS, gyrB, tufA dnaA was designed in total 3468 bp were analysed for each strain. offers highly discriminatory method capable subdividing 53 into 17 distinct types, largely according to geographical origin. detected...
Respiratory diseases in boid snakes are common captivity, but little information is available on their aetiology. This study was carried out to determine the occurrence of lung associated pathogens with and without respiratory signs and/or pneumonia. In total, 80 families Boidae (n = 30) Pythonidae 50) from 48 private zoo collections were included this survey. Husbandry conditions evaluated using a detailed questionnaire. All examined clinically grouped into or signs. Tracheal wash samples...
Respiratory infections, although showing common clinical symptoms like pneumonia, are caused by bacterial, viral or parasitic agents. These often reported in sheep and goats populations cause huge economic losses to the animal owners developing countries. Detection of these diseases is routinely done using ELISA microbiological methods which being reinforced replaced molecular based detection including multiplex assays, where different pathogens carried out a single reaction. In present...
The present study was conducted from July to August 2018 on milk samples taken at dairy farms in the Northern Province and Kigali District of Rwanda order identify Staphylococcus spp. associated with bovine intramammary infection. A total 161 staphylococcal isolates originating quarter 112 crossbred cattle were included study. Antimicrobial susceptibility testing performed examined for presence various resistance genes. aureus also analyzed virulence factors, genotyped by spa typing further...
In veterinary diagnostic laboratories, identification of mycoplasmas is achieved by demanding, cost-intensive, and time-consuming methods that rely on antigenic or genetic identification.
Information about livestock carrying methicillin-resistant coagulase-negative staphylococci and mammaliicocci (MRCoNS/MRM) is scarce. The study was designed to gain knowledge of the prevalence, phenotypic genotypic antimicrobial resistance genetic diversity MRCoNS/MRM originating from ruminants New World camelids. In addition, a multi-locus sequence typing scheme for characterization Mammaliicoccus (formerly Staphylococcus) sciuri developed. conducted April 2014 January 2017 at University...
Four coagulase-negative, novobiocin-resistant cocci, designated CW1(T), PM34, MM3 and RW78, were isolated from the respiratory tract of goats kept in Himalayan region. The four isolates assigned to a single species on basis almost identical biochemical physiological traits, protein profiles obtained after SDS-PAGE genomic fingerprints generated enterobacterial repetitive intergenic consensus (ERIC)-PCR. Strain CW1(T) showed highest 16S rDNA sequence similarities Staphylococcus cohnii subsp....
The present case is the first description of a triple infection with canine distemper virus (CDV), adenovirus (CAV) type 2, and Mycoplasma cynos in dog. 5-month-old female Miniature Pinscher was euthanized because dyspnea, croaking lung sounds, weight loss, lymphopenia. Pathologic examination revealed fibrinous necrotizing pneumonia large amphophilic intranuclear acidophilic intracytoplasmatic inclusion bodies different cells. Immunohistochemically, CDV antigen many other organs. In situ...
