In the period 1980 to 1986, 127 free range koalas from the north coast of New South Wales were presented for necropsy. Thirty-three koalas had urogenital disease alone, 8 had respiratory disease alone, 2 had digestive tract disease alone, 12 had multiorgan disease, 48 had traumatic injuries, 6 had neoplasia, 3 had miscellaneous conditions, while 15 had no significant lesions. Common naturally occurring disease entities included cystitis, conjunctivitis, paraovarian cysts, metritis and pneumonia. Lymphosarcoma was the common neoplasm.  相似文献

Emphysematous cystitis unassociated with diabetes mellitus was diagnosed in two dogs. One dog had chronic recurring urinary tract infection with aerobic and anaerboic bacteria, and the other had urinary tract infection associated with renal glucosuria. In both dogs, the cystitis was resolved with appropriate antibacterial therapy.  相似文献

Forty three koalas in a captive colony were investigated for the presence of Chlamydia psittaci infection and associated disease. Swabs were taken from conjunctivae and urogenital sites for cell culture isolation of C psittaci and for cytological examination (direct smears) for chlamydial inclusions and evidence of inflammation. On the basis of cell culture isolation, 28 samples from 25 koalas were positive for C psittaci (that is, infected). Three koalas were positive from both sites, 5 from conjunctivae alone and 17 from urogenital sites alone. Seven of the 8 koalas with positive conjunctival swabs had overt signs of conjunctivitis, but only 3 of the 20 koalas with positive urogenital swabs had overt signs of 'wet bottom' (continual urine soiling due to cystitis) or purulent discharge. However, 5 of the 20 with positive urogenital swabs had past episodes of 'wet bottom'. Moreover, examination of direct cytological smears showed evidence of inflammation (neutrophils) in 7 of 8 koalas with positive conjunctival swabs and 17 of 20 with positive urogenital swabs. Chlamydial inclusions were rarely identified with surety on direct cytological smears. In the 18 koalas without chlamydia, one had overt conjunctivitis while 2 had past episodes of conjunctivitis. The koala with conjunctivitis at the time of sampling had a prior history of 'wet bottom'. Examination of direct cytological smears revealed 2 of the chlamydial negative koalas had high numbers of neutrophils in urogenital smears. It was concluded that C psittaci infection may cause overt or sub-clinical disease, with the former developing when the koalas were stressed through management procedures or concomitant disease.  相似文献

An abattoir survey of urinary bladder lesions in cattle   总被引：1，自引：0，他引：1       下载免费PDF全文
Postmortem examination of 21,340 cattle at an Ontario abattoir over a one-year period revealed macroscopic lesions in urinary bladders of 2,296 animals (10.8%). Chronic cystitis, the most frequent finding, was observed in 2,209 cases (10.4%); uroliths were found in 994 (4.7%) of the cattle with chronic cystitis. Other types of urinary bladder lesions included acute cystitis, developmental abnormalities, hyperplasia, neoplasia, emphysema, and a parasitic cystitis.  相似文献

Complex interactions between Chlamydia pecorum infection, the immune response and disease exist in the koala. We used quantitative polymerase chain reaction to investigate the relationship between C. pecorum infectious load and ocular and urogenital tract disease. Chlamydia pecorum shedding was generally higher in animals with chronic, active disease than in animals with inactive disease. The absence of ocular disease was generally associated with low levels of shedding, but relatively high levels of shedding in the urogenital tract were detected in some koalas without clinical disease signs. These results suggest a complex disease pathogenesis and clinical course in C. pecorum-infected koalas.  相似文献

Objective To describe proctitis associated with chlamydial infection in a koala.
Design A pathological study  

Animal


A free living, male koala aged 17 years.
Procedure Rectum was examined histologically and chlamydial organisms visualised using Giminez stain and an immunoperoxidase staining method using an anti- Chlamydia lipopolysaccharide (genus specific) antibody.
Results An aged koala presented for euthanasia was found to have asymptomatic chronic proctitis, cystitis, prostatitis, urethritis and conjunctivitis associated with chlamydial infection. Inflammation was severe in the terminal rectum and extended into the proximal common vestibule. Chlamydial organisms were visualised in the rectal surface epithelium using Giminez stain and an immunoperoxidase staining method. Organisms were also detected in the epithelium of the bladder, prostate and urethra.  

Clinical Implications


Possible modes of transmission for the rectal infection are direct sexual transmission or ascending infection by organisms shed from the urogenital tract into the common vestibule. Previously unreported chlamydial proctitis in the koala may represent a potential reservoir of infection for other koalas.  相似文献

SUMMARY Four female koalas were found to have pyometra and pyovagina at autopsy. All had soiling of fur around the cloaca and were in poor condition. One koala had cystic ovaries in addition to the pyometra while another had extensive peritonitis due to rupture of one of the uterine horns. Chronic cystitis was present in all koalas while one also had pyelonephritis. Microbiological examination revealed a mixed flora of both aerobes and anaerobes.  相似文献

A total of 500 streptococci from two indications of swine (beta-haemolytic streptococci from infections of the urinary/genital tract including strains from the mastitis metritis agalactia syndrome as well as S. suis from infections of the central nervous system and the musculoskeletal system), two indications of horses (S. equi from respiratory tract infections and beta-haemolytic streptococci from infections of the genital tract), as well as three indications of dogs and cats (beta-haemolytic streptococci from infections of the respiratory tract, the urinary/genital tract, and skin/ear/mouth) were investigated for their susceptibility to antimicrobial agents. Regardless of the animal origin and indication, the most frequently detected resistance properties were resistances against sulfamethoxazole (20-78%), tetracycline (17-93%) as well as gentamicin (14-79%). Resistance to penicillins or cephalosporins was very rarely detected - if at all.  相似文献

Mycoplasmas identified as Mycoplasma canis were isolated from nine dogs with clinical signs of urogenital disease in Norway over a period of 20 months. Some of the dogs had been treated unsuccessfully with antibiotics, and three were euthanased as a result of severe persistent disease. Seven of the dogs had a urinary tract infection, one had chronic purulent epididymitis and one had chronic prostatitis. Overt haematuria was frequently observed among the dogs with cystitis. M canis was isolated in pure culture from seven of the dogs and in mixed culture from the other two. In three cases the mycoplasma was cultivated only from urinary sediment, and it was typically obtained in smaller numbers than would be considered indicative of a urinary tract infection. In contrast with most mycoplasmas, the M canis isolated from all the dogs grew on ordinary blood agar plates used for routine bacteriological cultivation. Specific mycoplasma media were not used and the presence of other Mycoplasma or Ureaplasma species cannot be excluded.  相似文献

OBJECTIVE: To evaluate the outcome of urinary bladder marsupialization in male goats. STUDY DESIGN: Prospective, experimental study. ANIMALS: Six healthy mixed-breed male goats. METHODS: After experimentally induced urethral obstruction, 6 male goats had urinary bladder marsupialization. Renal ultrasonography, complete blood count, and serum biochemical analysis were evaluated preoperatively (day 0), at 7 postoperative days, and then at 30-day intervals until 180 days. Stomal diameter was recorded immediately postoperatively and at each postoperative interval. Necropsy examination was performed on day 180 or when stomal stricture or death occurred. RESULTS: Stomal stricture occurred in 1 goat at 120 days. Another goat was found dead at 150 days; severe, suppurative cystitis was identified on necropsy. All goats had mild urine scald dermatitis. Serum biochemical values remained within normal limits, but significant decreases in white blood cell count, serum creatinine concentration, and stomal diameter occurred. At necropsy, all bladders were tubular in shape. Histological evidence of chronic suppurative cystitis and chronic, mild lymphoplasmacytic pyelitis occurred in all goats. Bacterial culture of renal tissue yielded growth in 3 goats, and bladder mucosal swabs yielded bacterial growth in all goats. CONCLUSIONS: Although clinical signs of ascending urinary tract infection were not observed in goats with patent stomata, urinary bladder marsupialization may result in ascending urinary tract inflammation or infection. CLINICAL RELEVANCE: Based on our results, urinary bladder marsupialization should be recommended with caution as the primary method for management of urinary tract obstruction in clinical cases.  相似文献

Indwelling urinary catheters with a closed urine collection system were maintained in 30 male cats for 3 days after induction of irritant cystitis. All cats received subcutaneous fluids during the 3 days the catheters were in place. The effects of four different treatment regimens on urinary tract infection rates, incidence of urethral obstruction, and development of urinary tract lesions over a 10-day period were compared with results in a nontreated group. Treatments were 1) amoxicillin for 5 days PO; 2) prednisolone for 5 days PO; 3) both amoxicillin and prednisolone for 5 days PO; and 4) dimethylsulfoxide (DMSO) for 3 days intravesicularly. Euthanasia was done before the end of the 10-day experimental period if the cats had two bouts of urethral obstruction or if the cats became uremic for causes unrelated to urethral obstruction. Seven cats were euthanatized before the conclusion of the experiment. These cats had been treated with prednisolone, prednisolone and amoxicillin, or DMSO. All cats that received amoxicillin alone or no therapy survived the 10-day period. Mortality was due to repeated urethral obstruction or to uremia associated with pyelonephritis or papillitis. Urinary tract infection rate was similar in all groups. The group treated with prednisolone alone had the highest incidence of renal infection. Inflammatory lesions in the lower urinary tract were similar in all groups. In conclusion, persistent urinary tract infection often develops in cats with cystitis after indwelling urethral catheterization even when closed systems of urine drainage are used.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

Polypoid cystitis is a rare disease of the urinary bladder in dogs characterized by inflammation, epithelial proliferation, and development of a polypoid mass or masses without histopathologic evidence of neoplasia. Medical records of 17 dogs with polypoid cystitis were reviewed to determine the clinical and laboratory features of this disorder and to assess treatment and outcome. Most affected dogs (15/17) were female and presented for evaluation of hematuria or recurrent urinary tract infection (UTI). Proteus spp were the most common bacterial isolates (12/52 or 23.1%) identified when all urine samples obtained for culture at any time during the course study were considered. Other commonly isolated organisms included Escherichia coli , Staphylococcus spp, and Enterococcus spp. Several dogs (7/17) also had cystic calculi at some time during the course of their disease. Most of the masses (11/14) were located cranioventrally in the bladder as opposed to transitional cell carcinoma, which has a predilection for the bladder neck or trigone area. It is unknown whether persistent or recurrent UTI predisposes to polyp formation or if polyps predispose to UTI. Surgery and removal of all polyps was the most efficacious treatment in dogs of this study. The question of whether or not polyps represent preneoplastic lesions remains unanswered and constitutes an area for future investigation.  相似文献

Based on the findings of physical examination and on laboratory findings the urinary bladder of 23 cows was examined endoscopically in order to investigate the application of cystoscopy in cattle. The endoscopic findings of all examined cows were compared with the findings of physical examination and the results of macroscopic and microscopic urinalysis and the bacteriological culture of the urine. By physical examination only 3 cows were diagnosed to have urinary tract disease, whereas all other cows were suspected of having an urinary tract disease. Bacteriological culture of the urine revealed Corynebacterium renale and Escherichia coli infection in 18 cows, while the remaining 5 cows were negative. By cystoscopy catarrhal cystitis was diagnosed in 2 cases, haemorrhagic cystitis in 5 cases, and fibrinous-purulent and fibrinous-haemorrhagic cystitis in 13 cases. Three cows showed no pathological changes of the urinary bladder mucosa by endoscopic examination. Cystoscopy facilitates diagnosis through the direct visualisation of mucosal lesions and makes it possible to give a more accurate prognosis based upon the findings.  相似文献

The epidemiologic features of feline immunodeficiency virus (FIV) infection were evaluated in 2,765 cats from the United States and Canada. Of these cats, 2,254 were considered by veterinarians to be at high risk for the infection, and 511 were healthy cats considered to be at low or unknown risk. Of the cats in the high-risk group, 318 (14%) were found to be infected with FIV. The infection rate among low- or unknown-risk cats was 6 of 511 (1.2%). Male cats in the high-risk group were 3 times more likely to be infected than were females, similarly as were cats greater than 6 years old, compared with younger cats; domestic cats, compared with purebred cats; and free-roaming cats, compared with confined cats. Feline immunodeficiency virus and FeLV infections did not appear to be linked with each other; 16% of FeLV-infected cats in the high- and low-risk groups were coinfected with FIV. In contrast, there was a pronounced linkage between FIV and feline syncytium-forming virus (FeSFV) infections. Seventy-four percent of FeSFV-infected cats in the high-risk study group were coinfected with FIV, compared with a 38% FIV infection rate among cats that were not infected with FeSFV. The major clinical manifestations associated with FIV infection in cats that were surveyed included chronic oral cavity infections (56%), chronic upper respiratory tract disease (34%), chronic enteritis (19%), and chronic conjunctivitis (11%). Bacterial infections of the urinary tract (cystitis), skin, and ears were seen in a small proportion of cats.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

The urogenital system was involved in 92 (22.9 per cent) of 401 malformed lambs examined over a three year period; genital 69 (six males: one female) and urinary 23 (three males: one female). Ten lambs had both genital and urinary defects. Sixty-eight (73.0 per cent) of the 92 lambs had defects of other organs, the most common being atresia ani, various skeletal and central nervous system defects, and arthrogryposis. The most common external defect of the male genital system was partial to complete cleft of the scrotum and the most common internal defect was cryptorchidism (six unilateral and 12 bilateral). Both penile agenesis and diphallia were observed twice. Defects of the female genital system included two uterine agenesis, four atresia vaginam, and one freemartin. Male pseudohermaphroditism was found in three lambs. The most common external urinary defect was male hypospadias and the most common internal defect was renal agenesis (12 unilateral and one bilateral). Other urinary defects were hydronephrosis (two unilateral and two bilateral), cystic kidneys (four unilateral and two bilateral), one bilateral polycystic kidneys, one patent urachus and six dysgenic kidneys.  相似文献

Haematological and biochemical investigations were performed on 14 koalas with uncomplicated cystitis, 8 with complicated cystitis, 8 with conjunctivitis, 8 with lymphosarcoma, and 14 with miscellaneous diseases. Changes were limited and inconsistent in individual koalas with uncomplicated cystitis and conjunctivitis. In contrast, individual koalas with complicated cystitis were more likely to have anaemia, leukocytosis due to neutrophilia, hypoproteinaemia due to hypoalbuminaemia, and azotaemia due to elevated urea concentration. Although these changes were non-specific they did allow assessment of prognosis for survival and response to treatment. Koalas with lymphosarcoma were invariably anaemic, leukaemic, azotaemic and hypoalbuminaemic. Elevated enzymes (aspartate transaminase [AST]. lactate dehydrogenase [LD] and gamma glutamyl transferase [GGT]) were more common in koalas with lymphosarcoma. Koalas affected by miscellaneous conditions showed variable changes but once again anaemia, leukocytosis, azotaemia, elevated AST and LD, and hypoalbuminaemia were not uncommon. On the basis of these findings a minimal profile is suggested for the investigation of sick koalas and would include haematocrit, total and differential leukocyte counts, urea, total protein and albumin concentrations and AST, GGT and LD activities.  相似文献

Lower urinary tract disease occurs commonly in cats and is often associated with crystal-related disease. Dietary modification is beneficial in managing some of these diseases, including idiopathic cystitis, urolithiasis, and urethral matrix-crystalline plugs. Altering dietary formulation may result in decreasing urinary concentrations of crystallogenic compounds, increasing urinary concentrations fo crystallogenic inhibitors, and diluting urine composition.  相似文献

Improved nutrition and client education have decreased the incidence of certain urinary tract diseases in ferrets. Early neutering programs at commercial breeding farms in the United States have also led to a marked decrease in the incidence of reproductive tract disease, especially estrogen-induced bone marrow suppression. However, the increased incidence of adrenal disease and its secondary effects on reproductive and associated urinary tract tissue presents an ongoing challenge for the clinician working with pet ferrets. Acute and chronic renal failure remain important, though less common, disease entities. It is imperative that the veterinarian working with pet ferrets be aware of the clinical presentation and clinicopathologic abnormalities associated with these syndromes.  相似文献

Oxalate nephrosis is a prevalent renal disease in koalas (Phascolarctos cinereus) of the Mount Lofty Ranges population in South Australia. The symmetric dimethylarginine (SDMA) assay is widely used in companion animals to diagnose renal disease, particularly in the early stages. This study aimed to determine: (1) reference intervals for SDMA in koalas and (2) SDMA values of koalas with oxalate nephrosis. Blood samples were collected from 41 Mount Lofty Ranges koalas euthanased on welfare grounds. Koalas were necropsied and, based on renal histopathology, were classified as unaffected (n = 22) or affected (n = 19) by oxalate nephrosis. Serum or plasma samples were analysed for creatinine, urea and SDMA and urine samples for urine specific gravity (USG). The reference interval for SDMA in unaffected koalas was 2.4–22.9 μg/dL. In koalas with oxalate nephrosis, SDMA was elevated in 74% of cases above the upper limit of the confidence interval. SDMA was elevated in three affected koalas with normal creatinine values. A positive correlation was found between SDMA and creatinine (R = 0.775, P < 0.001) and SDMA and urea (R = 0.580, P < 0.001) and a negative correlation between SDMA and USG (R = −0.495, P = 0.027). In conclusion, SDMA correlates well with other commonly used tests of renal function in koalas and should be included as part of the standard diagnostic process to increase the accuracy of oxalate nephrosis diagnosis in koalas.  相似文献
