| Abstract |
Paracoccidioidomycosis (PCM) is an endemic disease of humans from Latin America that is caused by Paracoccidioides brasiliensis and P. lutzii, with most cases of PCM in domestic animals being associated with P. brasiliensis. This study presents the clinical, cytological, mycological, serological, and molecular findings associated with P. brasiliensis in a dog from Southern Brazil. Fine needle biopsies were collected from the skin and several lymph nodes of a 5-year-old female Labrador dog that had enlargement of most superficial lymph nodes. Cytology of the skin and lymph nodes revealed pyogranulomatous dermatitis and lymphadenitis associated with fine-necked, budding fungal structures consistent with the Paracoccidioides genus of organisms; mycological culture derived from the lymph node aspirate demonstrated similar budding structures. Serological assays using exoantigens obtained from the fungal culture demonstrated that the fungal organisms derived from the lymph node were antigenically similar to P. brasiliensis by immunodiffusion and Western blot. A PCR assay, using the fungal culture as input, amplified a partial segment of the internal transcribed spacer 1 and 2 regions of P. brasiliensis; direct sequencing and phylogenetic analyses confirmed the PCR product as P. brasiliensis. The combined cytological, mycological, serological, and molecular findings confirmed a diagnosis of fungal dermatitis and lymphadenitis due to P. brasiliensis in this dog. This case represents the third description of clinical PCM in dogs and the first confirmation of mycotic dermatitis associated with P. brasiliensis in this species. The participation of dogs in the possible dissemination of PCM is reviewed, and it is proposed that dogs are probable accidental hosts in the epidemiological cycle associated with P. brasiliensis. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 16 March 2018.
All research outputs
#20,469,520
of 23,028,364 outputs
Outputs from Mycopathologia
#885
of 1,079 outputs
Outputs of similar age
#274,259
of 316,962 outputs
Outputs of similar age from Mycopathologia
#14
of 18 outputs
Altmetric has tracked 23,028,364 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,079 research outputs from this source. They receive a mean Attention Score of 3.6. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 316,962 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 18 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
