All cases were detected within fi ve months. Infections were confi rmed after positive fi ndings 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 nonspecifi c 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.

Urinary capillariosis in dogs. Veterinarski Glasnik, 2021. 75 (1): 20-32. https://doi.org/10.2298/VETGL191009003I Abstract Background. Urinary capillariosis in dogs is caused by Capillaria plica (syn. Pearsonema plica), a ubiquitous parasitic nematode resembling a string which belongs to the family Capillariidae. It parasitizes the feline, canine and musteline urinary bladder, and has been found in ureters and renal pelvises as well. C. plica has an indirect life cycle, with earthworms (Lumbricina) as intermediate hosts and domestic and wild animals (dog, cat, fox and wolf) as primary hosts. Infection of primary hosts occurs via ingestion of earthworms that contain infective first stadium (L1) larvae. An alternative path of infection for primary hosts is assumed to be ingestion of soil contaminated by infectious larvae derived from decomposed earthworms.

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.

    M. Pagnoncelli, R.T... França, D.B... Martins,,, et al., 2011. Capillaria sp. in a cat. sssssssssssssssssssssssssssssssssss Acta Scientiae Veterinariae. 39(3): 987. Acta Scientiae Veterinariae, 2011. 39(3): 987. CASE REPORT ISSN 1679-9216 (Online) Pub. 987 Capillaria sp. in a cat Marciélen Pagnoncelli, Raqueli Teresinha França, Danieli Brolo Martins,,, Flávia Howes,,, Sonia Teresinha dos Anjos Lopes & Cinthia Melazzo Mazzanti ABSTRACT Background: The family Capillariidae includes several species that parasite a wide variety of domestic and wild animals. Species such as Capillaria plica and Capillaria feliscati are found in the bladder, kidneys and ureters of domestic and wild carnivores. These nematodes are not still well known in Brazil, but have a great importance for studies of urinary tract diseases in domestic animals, mainly cats. The parasite’s life cycle is still unclear, may be direct or involve a paratenic host, such as the earthworm. Eggs are laid in the bladder and thus are discarded to the environment, where the larvae develop and are ingested by hosts. It is believed that the ingestion of soil and material contaminated with infective larvae derived from the decomposition of dead earthworms may be an alternative pathway for infection of animals. It has been reported in dogs a pre-patent period between 61 and 88 days. In Germany, the prevalence of C. plica in domestic cats was about 6%, with higher incidence in males, whereas in wild cats the prevalence of C. plica and C. feliscati was 7%, also with higher incidence in males. In Brazil, the first report of Capillaria sp. in a domestic cat was only done in 2008.

    Jpn. J. Infect. Dis., 58, 276-278, 2005 Original Article Is Aerobic Preputial Flora Age Dependent? Canan Aldirmaz Agartan*, Demet A. Kaya1, C. Elif Ozturk1 and Aynur Gulcan1 Department of Pediatric Surgery and 1Department of Microbiology, Medical School of Duzce, Abant Izzet Baysal University, Duzce, Turkey (Received April 4, 2005. Accepted July 1, 2005) SUMMARY: Urinary tract infection (UTI) is one of the most commonly encountered infections in childhood. It has been demonstrated that the preputial sac can act as a reservoir of organisms and is thus responsible for causing ascending UTIs. This study was performed to determine the presence of preputial flora in different age groups. Prepuce and urine samples were taken simultaneously from 92 uncircumcised and healthy male children aged between 0-12 years. The data were analyzed by age, with 47 subjects of 6 years of age or less, and 45 aged 7-12 years. Twenty-seven percent of the older patients had negative preputial cultures versus 8% of those under 6 years of age (χ2 = 5.27, P = 0.02). In addition, enteric bacteria were the most common pathogens isolated from the prepuce in younger children while skin flora bacteria were most common in the older group (χ2 = 9.18, P = 0.002). The urine was sterile in all cases. Preputial cultures change with age in uncircumcised boys. This change may be related to the development of immune status, to histological or anatomical changes in the prepuce, and/or to improved personal hygiene. born foreskins (12), but in the adult prepuce, Langerhans cells INTRODUCTION are easily identified in the mucosal epithelium.
