“…Recently, it was suggested that P. plica might be a contributing factor in glomerular amyloidosis in dogs (Callegari et al 2010). However, urinary bladder pathology, microscopic in particular, associated with P. plica infection in foxes was rarely investigated.…”

Pearsonema plica is a widely distributed nematode parasite that occurs in the urinary tract of various domestic and wild carnivores. The aim of this study was to investigate the occurrence and geographical distribution of P. plica and associated urinary bladder pathology in 112 red foxes (70 males, 42 females; 87 adults >1 year, 25 juveniles <1 year) from six different geographical regions in Bosnia and Herzegovina. The urinary bladders of the red foxes were subjected to gross examination and histopathology. Urine content (n = 40) and mucosal smears (n = 71) of the urinary bladders were examined microscopically for the presence of P. plica. Overall, adults and eggs of P. plica were detected in 65 (58.0 %; 95% CI 48.9-67.2%) of the foxes. Out of the positive foxes, 42 were males (64.6%) and 23 females (35.3%). According to age, 49 adults (75.3%) and 16 juveniles (24.6%) were positive. There were no statistically significant differences in the infection prevalence between the geographical regions (p = 0.701), sex (p = 0.693), or age (p = 0.646) of the host. Also, no significant differences in the prevalence of parasites in urine content (48.7%; 20/41) and mucosal smears (63.3%; 45/71) were observed (p = 0.165). Eosinophilic cystitis characterized with mild to severe infiltrates of eosinophils in the propria of the bladder mucosa accompanied by hyperemia and edema was observed in 36 examined foxes, 24 of which were P. plica positive. Parasites attached and embedded into the mucosa and free in the lumen were recorded in both cystitis positive and negative foxes. Beside clear numerical differences, the influence of P. plica infection on the occurrence of cystitis was not significant (p = 0.309). The results of this study give the first insight into the distribution of P. plica infection among the red fox population in Bosnia and Herzegovina. Observed microscopic changes may contribute toward a better understanding of pathology caused by this widely distributed parasite in free-ranging red foxes.

“…P. plica infects the urinary tract of domestic and wild carnivores worldwide (Basso et al, 2013). The adult worms are thread-like, whitish nematodes that live superfi cially attached to or are buried within the bladder mucosa whereas the ureters and renal pelvis are seldom affected (Callegari et al, 2010). P. plica is considered to be of low pathogenic signifi cance and in most cases parasite establishes only asymptomatic infections (Fernández-Aguilar et al, 2010).…”

“…P. plica is considered to be of low pathogenic signifi cance and in most cases parasite establishes only asymptomatic infections (Fernández-Aguilar et al, 2010). However, in heavy parasite loads P. plica has been found to be responsible for urinary signs and lesions in both carnivore pets (Callegari et al, 2010;Rossi et al, 2011;Basso et al, 2013) and wild canids (Fernández-Aguilar et al, 2010;Bork-Mimm & Rinder, 2011;Alić et al, 2015). In wolves, P. plica infection has been previously reported in Belarus (Shimalov & Shimalov, 2000), Spain (Segovia et al, 2001) and Latvia (Bagrade et al, 2009).…”

Research Note. Pearsonema plica and Eucoleus böhmi infections and associated lesions in wolves (Canis lupus) from Italy

SummaryReports of Pearsonema plica and Eucoleus böhmi infections in wolves (Canis lupus) in Europe are limited and data on associated lesions are lacking. In the present study urinary bladders, nasal turbinates and faecal samples from 8 necropsied wolves were examined for P. plica and E. böhmi infections and associated lesions. P. plica was identifi ed in the bladder of four wolves. At histological examination, follicular chronic cystitis and eosinophilic cystitis were found. E. böhmi nematodes and eggs were identifi ed from the nasal turbinates and rectal faecal samples of three wolves. Worms and eggs were found embedded in the mucosa among the nasal bone laminae. Two wolves were found coinfected by P. plica and E. böhmi. This is the fi rst report of P. plica and E. böhmi infections in wolves from Italy and the fi rst description of pathological lesions associated with P. plica infection in wolves.

“…Severe symptoms in infected dogs have been known for decades (Senior et al 1980;Spillmann and Glardon 1989). Very recently, C. plica has also been suggested to be a contributing factor in glomerular amyloidosis in dogs (Callegari et al 2010). The most recent studies concerning the occurrence of C. plica in German foxes were carried out in 1988 and 1994, reporting prevalences of 36.65% and 98.3% in the States of Schleswig-Holstein and Lower Saxony, respectively (Table 1), both of which are located in the North of Germany.…”

The nematode Capillaria plica is an ubiquitous parasite of the urinary tract of Canidae and Felidae. It causes a wide spectrum of clinical symptoms, ranging from asymptomatic infections to urinary bladder inflammation, pollacisuria, dysuria, and hematuria. Foxes serve as reservoir hosts and are considered to be a potential source of infection for companion and hunting dogs as well as domestic cats which acquire the infection by ingestion of earthworms which are the intermediate hosts. Despite its importance, epidemiological studies on this parasite are scarce and almost entirely lacking altogether for Central Europe. Therefore, we examined 116 red foxes (Vulpes vulpes) for the infection of C. plica by pathologic examination of the urinary bladders and microscopy of mucosal smears and urine sediments. The parasite was detected in 90 (78%; 95% CI, 68.9-84.8%) of the foxes, originating from all administrative districts of Bavaria (Southern Germany). Since Bavaria is characterized by a high number of forests and wildlife sanctuaries that provide ideal living conditions for foxes, the corresponding risk of infection of companion and hunting dogs by oral ingestion of earthworms as the intermediate hosts can likewise not be excluded. Because of the scarcity of reports on prevalences of C. plica worldwide, we also include a brief review of the available literature.
