Abstract
Abstract
Background
Urinary tract infestation by Capillaria spp. in domestic cats is rather rare, but can cause clinical symptoms and affect behaviour. To our knowledge, this report is the first to describe a case of urinary capillariosis in a cat in Poland.
Case presentation
A female formerly stray cat aged about 1.5 years showing dysuria, stranguria, periuria and lethargy was presented at the veterinary clinic. Urinalysis revealed the presence of Capillaria plica eggs in the sediment. The cat was treated successfully with three topical doses of Broadline (Merial, Toulouse, France).
Conclusions
C. plica is a nematode whose definitive hosts are carnivores, which are infected by eating earthworms (the intermediate hosts). Thus, C. plica infestation is more frequent in wild carnivores and dogs, and rare in cats. Symptomatic bladder capillariosis in cats is very rarely diagnosed and described.

Pathology of Urinary Bladder in Pearsonema spp. Infected Wildlife from Central Italy. Pathogens 2021; 10:pathogens10040474. [PMID: 33919805 PMCID: PMC8070773 DOI: 10.3390/pathogens10040474] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 04/09/2021] [Accepted: 04/11/2021] [Indexed: 11/16/2022] Open
Abstract
The genus Pearsonema, in the nematode family Capillariidae, includes several species that parasitize the urinary bladders of wild and domestic carnivores. The infection has been reported worldwide from several wildlife species, including canids, mustelids, and felids, but the pathological aspects have seldom been investigated. In order to assess the presence and severity of the lesions in Pearsonema-infected wildlife, we performed a parasitological and pathological examination of urinary bladders from 72 animals, belonging to the families Canidae (red fox Vulpes vulpes, n = 28, and wolf Canis lupus, n = 29) and Mustelidae (beech marten Martes foina, n = 3; pine marten Martes martes, n = 2; and European badger Meles meles, n = 10). A greater prevalence of infection for canids (64.91%; 95% confidence interval (95% CI), 52.52–77.30%) than for mustelids (13.33%) (p < 0.001) was recorded. The prevalence of infection in red foxes was 75.0% (95% CI, 58.96–91.04%), in accordance with other reports from European countries, supporting the role of this species as a reservoir for infection. Eosinophilic cystitis was observed in 34 out of the 72 examined animals (47.22%). The influence of Pearsonema sp. infection on the occurrence of eosinophilic cystitis was statistically significant in wolves (p < 0.01), which were also affected by more severe histological lesions compared to foxes.

Abstract
Pearsonema (syn. Capillaria) plica is a nematode that resides in the urinary bladder of canids, felids and mustelids (definitive hosts) and is classified in the same class as Trichuris spp. Epidemiological and clinical data on Pearsonema plica infection in domestic animals are limited. The nematode has an indirect lifecycle that involves earthworms as intermediate hosts. A six-year-old crossbred dog from Greece, presented a history of intermittent pollakiuria and hematuria. At urine analysis, P. plica eggs were found in the urine sediment. The dog was successfully treated with a double dose of milbemycin. To the best of our knowledge this is the first case of urinary capillariasis diagnosed in a domestic animal in Greece.

Capillaria plica in Red Foxes (Vulpes vulpes) from Serbia: Epidemiology and Diagnostic Approaches to Urinary Capillariosis in Domestic Carnivores. Acta Parasitol 2020; 65:954-962. [PMID: 32601819 DOI: 10.1007/s11686-020-00244-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Accepted: 06/17/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE This study aimed to determine the presence of C. plica in red foxes and to point out the possibilities of different diagnostic methods, that could be used for diagnosis of urinary capillariosis in domestic carnivores. METHODS Seventeen red foxes from hunting grounds in the Kolubara District, Republic of Serbia, were examined in February 2019. Animals to be shot were selected based on the criteria of gamekeepers and the permission of the competent Ministry. After hunting, the foxes were examined by ultrasound and autopsied. After the necropsy, biochemical and sediment analysis of urine morphological identification of isolated adult parasites, and macroscopic/microscopic examination of the urinary bladder and kidney tissue were performed. RESULTS Adults of C. plica were detected in 3/17 foxes (17.6%) by ultrasound imaging and in 6/17 foxes (35.3%) by necropsy examination. Parasite eggs were found in the urinary sediment of 9/17 foxes (52.9%). The predominant histopathologic changes were amyloid degeneration of the renal glomeruli and proximal tubules (8/17 foxes-47%) as well as acute cystitis (7/17 foxes-41.2%). The occurrence of C. plica was determined in 12/17 (70.6%) of the examined foxes. DISCUSSION This study is the first record of the C. plica in red foxes in the Republic of Serbia. Diagnostic methods used in this study could make possible the early revealing of capillariosis in domestic carnivores and could provide reliable clinical and parasitological screening of suspect animals. CONCLUSION The study presents the first report of urinary capillariosis in a fox population in Serbia. The established high prevalence of C. plica in foxes could presume its higher prevalence in domestic and wild carnivores in the future.

Abstract
Nematodes of the urinary tract of domestic dogs and cats are a rare occurrence. The discovery of the eggs on urine sediment examination is usually an incidental finding. A twenty-one month old intact queen presented to the Veterinary Teaching Hospital with a history of a serosanguinous vaginal discharge and reddish colour urine for the last ten days. Complete blood count and biochemistry analysis revealed an inflammatory leukogram and a hyperproteinaemia. A urogenital tract infection was diagnosed as haematuria, pyuria, bacteriuria, proteinuria and alkaline urine were evident on urinalysis examination. Microscopic examination of the urine sediment also detected eggs with asymmetrical bipolar plugs characteristic for Pearsonema species. A distended uterus as well as a raised lesion in the mucosal layer of the urinary bladder were observed with ultrasonography. A routine ovariohysterectomy was performed. The cat was also treated with ivermectin and amoxicillin. The cat improved with the eventual resolution of the red colour urine and serosanguinous vaginal discharge.

Abstract
Simple Summary Pearsonema spp. nematodes live in the urinary bladder and sometimes in the ureters and renal pelvis of domestic and wild carnivores, in which they may be responsible for urinary capillariosis. While the red fox is considered a reservoir of Pearsonema plica, the occurrence of Pearsonema spp. infection in domestic carnivores is still poorly known. This study aimed to assess the occurrence of Pearsonema spp. infection in privately owned cats and dogs from central (Tuscany) and northern Italy (Piedmont and Lombardy) alongside its occurrence in a red fox population from central Italy (Tuscany). Among the examined animals, 2/26 cats (7.7%), 1/83 dogs (1.2%), and 38/42 foxes (90.5%) were found positive. Recurrent cystitis, pollakiuria, and hematuria were the main clinical signs in symptomatic dogs and cats. This is the first study on Pearsonema spp. infection of domestic carnivores examining a large number of privately owned pet animals. Obtained results confirm the role of the red fox as a reservoir for P. plica in Europe and suggest a possible high occurrence of Pearsonema spp. infection in domestic cats of central Italy. Abstract Pearsonema spp. nematodes infect the urinary bladder of domestic and wild carnivores. The red fox is considered a reservoir of Pearsonema plica, while the prevalence of Pearsonema spp. in domestic carnivores is still poorly known. This study aimed to assess the occurrence of Pearsonema spp. infection in privately owned cats (26) and dogs (83) from central and northern Italy alongside occurrence in red foxes (42) from central Italy. In positive dogs and cats, associated clinical signs were also evaluated. Urine samples were first examined under a stereomicroscope; then, they were centrifuged and microscopically examined after a flotation test. As for foxes, the urinary bladders were opened and urine was collected and processed as above, while collected nematodes were identified at the species level. Among examined animals, 2/26 cats (7.7%), 1/83 dogs (1.2%), and 38/42 foxes (90.5%) scored positive. Recurrent cystitis, pollakiuria, and hematuria were the main clinical signs in symptomatic dogs and cats. This is the first study on Pearsonema spp. infection in domestic carnivores examining a large number of privately owned pet animals. Obtained results confirm the role of the red fox as a reservoir for P. plica and suggest a possible high occurrence of Pearsonema spp. infection in domestic cats of central Italy.

Abstract
Three clinical cases of dogs with Pearsonema plica infection were detected in the western part of Slovakia. All cases were detected within five months. Infections were confirmed after positive findings of capillarid eggs in the urine sediment in following breeds. The eight years old Jack Russell Terrier, one year old Italian Greyhound, and eleven years old Yorkshire terrier were examined and treated. In one case, the infection was found accidentally in clinically healthy dog. Two other patients had nonspecific clinical signs such as apathy, inappetence, vomiting, polydipsia and frequent urination. This paper describes three individual cases, including the case history, clinical signs, examinations, and therapies. All data were obtained by attending veterinarian as well as by dog owners.

Abstract
Capillaria spp. infections of the urinary tract of domestic carnivores are uncommon worldwide. Infections are rarely diagnosed and are typically asymptomatic. This study aimed to evaluate a case of capillariosis in a cat from the state of Rio de Janeiro, Brazil. A seven-year-old female cat with apathy and reduced appetite was presented. Urine analysis revealed C. plica eggs in urine sediment, and cystitis was evidenced by the presence of bacteria, pyuria, proteinuria and hematuria. The subject was treated with 50 mg/kg fenbendazole for five days. Urine samples were frozen for molecular analysis and species confirmation. Polymerase chain reaction for amplification of the 18S rRNA gene followed by sequencing confirmed the occurrence of Capillaria sp. There has been limited phylogenetic study of Capillaria spp. in cats, so further studies are needed to identify the species present in different locations and associated with feline pathogenesis.

Abstract
Extraintestinal nematodes have been seldom investigated in the brown bear (Ursus arctos). In this study, a case of urinary capillariosis and bladder associated lesions is reported in a deceased free-ranging Marsican brown bear (Ursus arctos marsicanus) from Central Italy. Gross lesions in the urinary bladder consisted of scattered foci of mucosal hyperemia, while at histological examination mild cystitis was observed. At microscopic examination of urine and bladder lavage fluid, capillariid adult female nematodes and eggs were found, suspected of belonging to the genus Pearsonema based on their location in the urinary bladder. This is the first report of Pearsonema infection and associated bladder lesions in a brown bear. Capillariid nematodes were found in the urinary bladder of a Marsican brown bear. Based on morphology and location, a Pearsonema species was suspected. Scattered hyperemic foci in the bladder mucosa and mild cystitis were observed. This is the first report of cystitis associated with Pearsonema infection in a bear.

Abstract
Urinary bladder worm infection is relatively uncommon in pet dogs and cats in the Americas. This report describes the diagnosis of lower urinary tract infection by Pearsonema plica in two asymptomatic dogs and P. feliscati in a cat with lower urinary tract clinical signs diagnosed between 2002 and 2015, and the first report of this type of parasitism in domestic small animals in Mexico at an altitude above 2600 m above sea level. The studied cases demonstrate the need to consider a urinary bladder worm infection in domestic small animals, both stray animals and those with controlled access to the streets. Although a definitive host as foxes does not exist among the urban wildlife in cities of the Americas, stray dogs and cats should be considered as potential reservoir hosts of Pearsonema, which requires future epidemiological studies in these populations.

Abstract
Canine urinary capillariosis is caused by the nematode Pearsonema plica. P. plica infection is seldomly detected in clinical practice mainly due to diagnostic limitations. This report describes six cases of urinary capillariosis in dogs from Italy. Recurrent cystitis was observed in one dog, whereas another patient was affected by glomerular amyloidosis. In the remaining animals, the infection was considered an incidental finding. Immature eggs of the parasite were observed with urine sediment examination in 3/6 patients. Increased awareness of the potential pathogenic role of P. plica and clinical disease presentation could help identify infected animals.

Abstract
Worldwide, data on Capillaria (Pearsonema) plica infections of the urinary tract in domestic carnivores are limited. Nevertheless, cystitis with hematuria, dysuria or pollakiuria may suggest a C. plica infection. A three-year old dog from Poland showing pollakiuria and hematuria was presented. At urine analysis, C. plica eggs were found in the urine sediment. The dog was unsuccessfully treated with a daily oral dose of fenbendazole 50 mg/kg BW for 5 days, while a single subcutaneous administration of ivermectin 0.2 mg/kg BW once effectively eliminated C. plica infection.

Abstract
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.

Abstract
Background Capillaria plica (syn. Pearsonema plica) is a nematode that resides in the urinary bladder and rarely in ureters or in the kidney pelvis of various carnivores, especially foxes and dogs. Urine sedimentation technique is actually the only diagnostic tool that permits the identification of C. plica eggs, but its sensitivity is low and when an infection is suspected (or when it is necessary to confirm treatment efficacy) more than one examination of urine sediment should be performed. The present paper reports a clinical case of natural C. plica infection in a dog from southern Italy. In addition, two new techniques, FLOTAC and Mini-FLOTAC, were used for the diagnosis of C. plica in dog urine and compared with the technique of sedimentation. Results Using FLOTAC with fresh urine and sodium chloride as flotation solution, were obtained the best results for the diagnosis of C. plica in dog urine in term of eggs counted (mean eggs per 10 ml of urine = 70.3 FLOTAC vs 40.3 Mini FLOTAC vs 32.8 sedimentation) and coefficient of variation (CV%) (6.2 FLOTAC vs 13.4 Mini-FLOTAC vs 32.9 sedimentation). Conclusions The FLOTAC was the more sensitive method, but also the Mini-FLOTAC could be a valid alternative diagnostic method because gave better results than the classical sedimentation and can be used in place of the FLOTAC in laboratories where the centrifugation step cannot be performed.

Abstract
AbstractExtraintestinal nematodes of the red fox (Vulpes vulpes) are a wide group of parasites that infect wild and domestic carnivores and occasionally humans. Nematodes in the cardiopulmonary system, stomach, urinary apparatus and muscle tissue of 165 red foxes (Vulpes vulpes) from north-west Italy (Liguria and Piedmont) were investigated between 2009 and 2012. Of the cardiopulmonary nematodes, a high prevalence ofAngiostrongylus vasorumandEucoleus aerophilus(syn.Capillaria aerophila) was found, 78.2% and 41.8% respectively;Crenosoma vulpis(15.8%) andFilaroidesspp. (4.8%) were also found.Spirocerca lupi(23.5%),Aonchotheca putorii(syn.Capillaria putorii) (8.6%) andPhysalopteraspp. (2.5%) were detected in the stomach andPearsonema plica(syn.Capillaria plica) (56.8%) in the bladder.Eucoleus boehmi(syn.Capillaria boehmi)was also detected in the nasal cavities of one of the two foxes examined. A coprological examination revealed eggs ofE. aerophilus,A. putorii,S. lupi,Physalopteraspp. and eggs of intestinal parasites. Filarial worms were absent in all the 165 animals examined, nor was there evidence ofTrichinellaspp. in any of the foxes. The foxes were found to host a high prevalence of many species of extraintestinal nematodes. The prevalence ofA. vasorumin foxes found in the present study is among the highest in Europe. In addition, to the best of our knowledge,E. boehmiandFilaroidesspp. have never been reported before in this host in Italy.

Abstract
Several species of Trichuridae nematodes can infect dogs, cats and wild mammals. The diagnosis of these infections relies on the microscopic identification of eggs which are characterized by a similar "lemon" shape and polar plugs in all Trichuridae. Thus, morphological diagnosis to species level is challenging. The use of biomolecular diagnostic methods is desirable but very little genetic data are known from Trichuridae of carnivores and small mammals. The aim of this work was to genetically characterize several species of Trichuridae that can affect dogs, cats and wild mammals, as a basis to develop molecular diagnostic tests. Specimens (adult worms or eggs) of Eucoleus aerophilus (syn. Capillaria aerophila), Eucoleus boehmi (syn. Capillaria boehmi), Pearsonema plica (syn. Capillaria plica), Aonchotheca putorii (syn. Capillaria putorii), Calodium hepaticum (syn. Capillaria hepatica), Calodium splenaecum (syn. Capillaria splenaeca) and Trichuris vulpis were obtained from carcasses of red foxes, feces of dogs, the liver of a vole and from the spleen of Crocidura sp. Parts of the small subunit rRNA (18S rRNA) gene and of the mitochondrial cytochrome c oxidase subunit I (cox 1 mtDNA) gene were amplified from the above mentioned nematodes, yielding the first 18S rRNA gene sequences of all the capillariid nematodes and the first cox 1 mtDNA sequences of E. boehmi, P. plica, C. hepaticum, A. putorii and T. vulpis. The 18S rRNA gene is highly conserved among the different species and not suitable as a target for specific diagnostic oligonucleotides. However, these sequences contribute to a better understanding of the complex taxonomic relations among Trichuridae. Indeed, a dendrogram based on the 18S rRNA gene locus supports the latest taxonomic revision. Interspecies divergence was much higher at the cox 1 mtDNA gene locus, rendering it suitable for DNA barcoding and particularly valuable in resolving closely related species. Furthermore, the mitochondrial genetic markers defined in the present study are useful to develop Trichuridae species-specific primers.
