Mycoplasma capricolum subsp. capricolum is one of the causative agents of contagious agalactia (CA). Nevertheless, there is still a lack of information about its antimicrobial susceptibility and genetic characteristics. Therefore, the aim of this work was to study the antimicrobial and genetic variability of different Mycoplasma capricolum subsp. capricolum field isolates. For this purpose, the growth inhibition effect of 18 antimicrobials and a multilocus sequence typing (MLST) scheme based on five housekeeping genes (fusA, glpQ, gyrB, lepA and rpoB) were performed on 32 selected field isolates from Italy and Spain...

Infection with Mycoplasma gallisepticum induces severe lymphoproliferative lesions in multiple sites along the respiratory tract in chickens and turkeys. These immunopathological responses have been well-characterised in chickens, but have not been studied closely in turkeys. The aim of the studies described here was to examine the immune responses of turkeys after live vaccination and infection with M. gallisepticum. In a strain comparison study, the mean log10 antibody titre of birds exposed to an aerosol culture of M...

We performed a retrospective chart review for all cases of recurrent Stevens Johnson Syndrome (SJS) from March 2013 to March 2016. Nine children had 29 episodes of SJS or incomplete SJS; all children were male and 8 (88%) were white. Episodes affected mucus membranes with minimal skin involvement. Mycoplasma infections and HLA-B27/-B51 were common.

Ovine footrot is a highly prevalent bacterial disease caused by Dichelobacter nodosus and characterised by the separation of the hoof horn from the underlying skin. The role of innate immune molecules and other bacterial communities in the development of footrot lesions remains unclear. This study shows a significant association between the high expression of IL1β and high D. nodosus load in footrot samples. Investigation of the microbial population identified distinct bacterial populations in the different disease stages and also depending on the level of inflammation...

Previous studies showed the presence of Mycoplasma pneumoniae (M. pneumoniae) and membrane-shed microparticles (MPs) in vulnerable atherosclerotic plaques. H&S Science and Biotechnology developed PTCTS, composed by natural particles from medicinal plants (PTC) combined with trans-Sialidase (TS), to combat MPs and Mycoplasma pneumoniae. Our aim was to determine the effects of the different components of PTCTS in a rabbit model of atherosclerosis. Rabbits were fed with high cholesterol diet for 12 weeks and treated during the last 6 weeks with either vehicle, PTC, TS, or PTCTS...

BACKGROUND: Acute necrotizing encephalopathy (ANE) is a rare but rapidly progressing encephalopathy following a febrile illness, commonly a viral infection. It is characterized by the features of acute encephalopathy such as seizure, alteration of consciousness, and symmetric involvement of the bilateral thalamus on neuroimaging tests. Although most ANE cases have occurred sporadically, familial or recurrent ANE has been reported in Caucasian patients, with genetic susceptibility to ANE noted in some patients due to a RANBP2 mutation...

BACKGROUND: Tick-borne diseases are of substantial concern worldwide for animals as well as humans. Dogs have been a human companion for millennia, and their significant impact on human life renders disease in dogs to be of great concern. Tick-borne diseases in dogs represent a substantial diagnostic challenge for veterinarians in that clinical signs are often diffuse and overlapping. In addition, co-infections with two or more pathogens enhance this problem further. Molecular methods are useful to disentangle co-infections and to accurately describe prevalence and geographical distribution of tick-borne diseases...

Contagious bovine pleuropneumonia (CBPP) was recognised on Bako Agricultural Research Farm, in the Oromia Region of Ethiopia, for the first time on 5 May 2011. The outbreak was investigated by combining recognition of clinical signs, post-mortem examination, mycoplasma isolation and serological testing using competitive enzymelinked immunosorbent assay (c-ELISA). The clinical cases were monitored for eight months; sick animals were treated with a range of antibiotics and isolated if necessary. The outbreak of CBPP was confirmed both bacteriologically and serologically and had spread to almost the entire herd (96...

BACKGROUND: The nasopharyngeal (NP) microbiota plays an important role in bovine health, comprising a rich and diverse microbial community. The nasopharynx is also the niche for potentially pathogenic agents which are associated with bovine respiratory disease (BRD), a serious and costly illness in feedlot cattle. We used 14 beef heifers from a closed and disease-free herd to assess the dynamics of the NP microbiota of cattle that are transported to a feedlot. Cattle were sampled prior to transport to the feedlot (day 0) and at days 2, 7, and 14...

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are life-threatening blistering disorders. Few studies have addressed SJS/TEN in children. We sought to determine risk factors, comorbidities, inpatient burden and mortality in US children with SJS, SJS-TEN and TEN. We analyzed data from the 2009-2012 Nationwide Inpatient Sample (NIS), containing a representative 20% sample of all hospitalizations in the US. SJS, SJS-TEN and TEN were identified by a validated algorithm using ICD-9-CM codes...

The purpose of this study was to compare the acute phase reaction (APR) induced by different vaccination protocols used against Porcine Circovirus (PCV) type-2 and Mycoplasma hyopneumoniae (M.hyo), studying two acute phase proteins (APPs) and changes in rectal temperature (RT). In addition, the possible influence of the time of vaccination and breed were analysed. In the first experiment, 40 commercial crossbred piglets were vaccinated, on the day of weaning, with FLEXcombo® (group A, n=20) or Porcilis PCV® and Stellamune® One (group B, n=20)...

It is well known that the most important etiologies of acute pancreatitis are gallstones and alcohol consumption. Once these causes have been ruled out, especially in young adults, it is important to consider less frequent etiologic factors such as drugs, trauma, malformations, autoimmunity or systemic diseases. Other rare and less well studied causes of this pathology are infections, among which Mycoplasma pneumoniae has been reported to cause acute pancreatitis as an unusual extrapulmonary manifestation. Here, we report the case of a 21-year-old patient who had acute idiopathic pancreatitis associated with an upper respiratory tract infection...

Mycoplasma pneumonia is a major pathogen of primary atypical pneumonia and has been known to cause various kinds of extrapulmonary manifestations involving almost all organs of the human body. Optic neuritis associated with M. pneumoniae infection has rarely been described and mostly, it combined other neurological complications including meningitis, meningoencephalitis, myelitis, and peripheral neuropathy. We report two patients who presented with isolated optic neuritis due to M. pneumoniae infection, and reviewed the literatures on five additional patients...

1.Understanding both contact and probability of transmission given contact are key to managing wildlife disease. However, wildlife disease research tends to focus on contact heterogeneity, in part because probability of transmission given contact is notoriously difficult to measure. Here we present a first step toward empirically investigating probability of transmission given contact in free-ranging wildlife. 2.We used measured contact networks to test whether bighorn sheep demographic states vary systematically in infectiousness or susceptibility to Mycoplasma ovipneumoniae, an agent responsible for bighorn sheep pneumonia...
