In August 2015, a gopher tortoise ( Gopherus polyphemus) mortality event was documented on a 40-ha area of Lake Louisa State Park, Lake County, Florida, USA. To quantify the extent of the die-off and the seroprevalence of Mycoplasma agassizii and Mycoplasma testudineum, two causative agents of mycoplasmal upper respiratory tract disease (URTD), we conducted a tortoise shell survey on 25 and 26 August 2015 and collected blood samples from live tortoises on 2-4 September 2015 and 1-13 August 2016 within the area of documented mortality...

Little is known about the presence of mycoplasmas in the genital tracts of domestic and stray bitches or in the vaginas of ovariohysterectomized (OHE) bitches. Moreover, to our knowledge, there has been no research to investigate the presence of canine vaginal mycoplasmas during the different stages of the reproductive cycle. We investigated the occurrence of mycoplasmas in the vaginas of healthy domestic and stray intact bitches, to correlate their presence with specific stages of the reproductive cycle, and to compare them with those in OHE bitches...

In recent years, the morbidity of Mycoplasma pneumoniae pneumonia (MPP) has dramatically increased in China. An increasing number of studies indicate that an imbalance in the respiratory microbiota is associated with respiratory infection. We selected 28 hospitalized patients infected with M. pneumoniae and 32 healthy children. Nasopharyngeal (NP) and oropharyngeal (OP) swabs were collected from healthy children, whereas NP, OP and bronchoalveolar lavage (BAL) specimens were collected from patients. Microbiota analysis was performed on all microbial samples using 16 S ribosomal RNA (16 S rRNA) sequencing...

Mycoplasma gallisepticum infection can lead to major financial losses for poultry producers. Control of M. gallisepticum infection in the layer industry is generally obtained through vaccination due to the nature of the multi-aged flocks in the facilities. Live vaccines can provide significant protection from the pathogenic effects of M. gallisepticum infection. However, differing management practices, including vaccination procedures, can lead to significant variations in the efficacy of the same vaccine. The site of vaccine deposition has been shown to be one important factor significantly influencing the vaccination outcome...

Functional genomics studies in minimal mycoplasma cells enable unobstructed access to some of the most fundamental processes in biology. Conventional transposon bombardment and gene knockout approaches often fail to reveal functions of genes that are essential for viability, where lethality precludes phenotypic characterization. Conditional inactivation of genes is effective for characterizing functions central to cell growth and division, but tools are limited for this purpose in mycoplasmas. Here we demonstrate systems for inducible repression of gene expression based on clustered regularly interspaced short palindromic repeats-mediated interference (CRISPRi) in Mycoplasma pneumoniae and synthetic Mycoplasma mycoides, two organisms with reduced genomes actively used in systems biology studies...

PURPOSE: Etiological diagnosis of pediatric patients with community-acquired pneumonia is difficult. For therapy, one of the major problems is the difficulty in separating bacterial pneumonia which would benefit from antibiotics from non-bacterial pneumonia. Therefore, we sought to identify potential biomarkers for distinguishing non-bacterial pneumonia from bacterial pneumonia. EXPERIMENTAL DESIGN: Lectin microarray containing 91 lectins was used to screen serums from pediatric patients with pneumonia...

BACKGROUND: Porcine parvovirus 2 (PPV2) was detected in swine serum without showing any relationship with disease. The emergence of the virus seemed to be a unique event until other genetically highly similar parvoviruses were identified in China and, later in 2012, the presence of the virus was also described in Europe. PPV2 is widely distributed in pig populations where it is suspected to be involved in respiratory conditions, based on its frequent detection in lung samples. In order to investigate the potential pathogenic involvement of PPV2, 60 dead pigs were examined from two farms...

Mycoplasma bovis is an important pathogen causing disease and substantial economic losses in cattle. However, knowledge of the dynamics of antibody responses in individual cows in the face of an outbreak is currently extremely limited. The use of commercial antibody tests to support clinical decision-making and for surveillance purposes is therefore challenging. Our objective was to describe the dynamics of M. bovis antibody responses in 4 Danish dairy herds experiencing an acute outbreak of M. bovis-associated disease, and to compare the antibody dynamics between dairy cows with different disease manifestations...

REVIEW

Mycoplasma hyopneumoniae (M. hyopneumoniae) is the primary causative agent of enzootic pneumonia (EP), one of the most economically important infectious disease for the swine industry worldwide. M. hyopneumoniae transmission occurs mainly by direct contact (nose-to-nose) between infected to susceptible pigs as well as from infected dams to their offspring (sow-to-piglet). Since disease severity has been correlated with M. hyopneumoniae prevalence at weaning in some studies, and gilts are considered the main bacterial shedders, an effective gilt acclimation program should help controlling M...

In this study differences in the placental microbiota of term and preterm deliveries from a large UK pregnancy cohort were studied using 16S targeted amplicon sequencing. The impact of contamination from DNA extraction, PCR reagents, as well as those from delivery itself were also examined. A total of 400 placental samples from 256 singleton pregnancies were analysed and differences investigated between spontaneous preterm, non-spontaneous preterm, and term delivered placenta. DNA from recently delivered placenta was extracted, and screening for bacterial DNA was carried out using targeted sequencing of the 16S rRNA gene on the Illumina MiSeq platform...

Antimicrobial peptides (AMPs) are a diverse group of molecules which play an important role in the innate immune response. Bovine NK-lysins, a type of AMP, have been predominantly found in the granules of cytotoxic T-lymphocytes and NK-cells. Bovine NK-lysin-derived peptides demonstrate antimicrobial activity against various bacterial pathogens, including several involved in bovine respiratory disease complex (BRDC) in cattle; however, such studies are yet to be performed with one important contributor to the BRDC, Mycoplasma bovis...

RATONALE: Sometimes, pleural effusion accompanying an acute Mycoplasma pneumoniae infection or tuberculous pleurisy has similar analysis results. We report a case of tuberculous pleurisy which was initially diagnosed as acute M pneumoniae infection, which is of special interest because anti-Mycoplasma antibody results were positive, which served as a red herring. PATIENT CONCERNS: A 20-year-old woman visited the outpatient emergency romm of our hospital for chief complaints of high fever, dry cough, and pleuralgia persiting for 2 days...

Oral mucoceles are lesions arising mainly from the minor salivary glands and are thought to occur after excretory duct trauma. We report a case of multiple superficial oral mucoceles on a child's labial mucosa after Mycoplasma pneumoniae mucositis. Mucoceles can mimic persistent or recurrent stomatitis and lead to potential errors in management.

Periodontitis is a kind of infectious disease initiated by colonization of subgingival periodontal pathogens, which cause destruction of tooth-supporting tissues, and is a predominant threat to oral health as the most common cause of loss of teeth. The aim of this pilot study was to characterize the subgingival bacterial biodiversity of periodontal pockets with different probing depths in patients with different forms of periodontitis. Twenty-one subgingival plaque samples were collected from three patients with chronic periodontitis (ChP), three patients with aggressive periodontitis (AgP) and three periodontally healthy subjects (PH)...
