Urinary capillariosis in a cat from Rio de Janeiro, Brazil - Clinical, morphological and phylogenetic characterization

Pearsonema spp. (Family Capillariidae, Order Enoplida) Infection in Domestic Carnivores in Central–Northern Italy and in a Red Fox Population from Central Italy

“…In previous epidemiological studies evaluating Pearsonema spp. infection in domestic carnivores, only stray and shelter animals have been considered [19][20][21]23,24,37], while only reports of single or few animal clinical cases are available for dogs and cats kept as pets [6,9,10,[23][24][25][26][27][28][29][30][31]. Therefore, this is the first study evaluating the occurrence of Pearsonema spp.…”

“…However, few epidemiological studies have been conducted in domestic dogs [19] and cats [20][21][22][23][24], and worldwide reports of Pearsonema spp. infections in pet domestic carnivores mostly consist of scattered clinical cases [10,[25][26][27][28][29][30][31], also from Italy [8,11,32,33].…”

“…infections may be underestimated. Nevertheless, in dogs and cats, the infection can present with overt clinical signs, especially if complicated by the intervention of other factors, mainly concurrent bacterial infections [10,11,25,27,28,33,34]. Dysuria, pollakiuria, hematuria, pyuria, and urine incontinence are the most commonly observed clinical signs [8,10,25,32,33].…”

An unexpected cause of dysuria in a cat in Poland

“…In both species, it can be self-limiting with no clinical sign [2,3]; thus, the actual incidence of bladder capillariosis can be assumed to be underestimated. Severe infection can cause abdominal pain, fever, lethargy, reduced appetite, dysuria, periuria, pollakiuria and haematuria [3,5,6,17]. Feline capillariosis may be associated with painful obstruction caused by adult nematodes in the ureter or renal pelvis, or urethral inflammation with submucosal oedema, and may lead to acute renal failure or predisposition to the development of feline urinary tract disease [5].…”

“…Only a few cases of bladder infection caused by Capillaria spp. in domestic cats have been described [1,[4][5][6], although post-mortem surveys conducted in Germany and Australia have revealed that the incidence of infestation with this parasite in cats ranges from 6 to 18.3% [3,7]. Most described cases of symptomatic infestation in domestic cats are with C. (Pearsonema) plica, but Capillaria feliscati and Capillaria travassoi infestations also occur [8].…”
