Background: Emphysematous pyelonephritis (EPN) is an acute, severe necrotizing infection of the renal parenchyma and surrounding tissues that results in gas formation in the kidney, collecting system, or surroundings. EPN is a rare condition in veterinary medicine and occurs most frequently in dogs with diabetes mellitus. Although the prognosis of medical management in animals is poor, the standardized treatment protocol according to EPN severity is unclear. This report describes the first case of a nondiabetic female cat with extensive EPN and good prognosis following direct nephroureterectomy (NU). Case: A 10-year-old spayed female cat presented with the chief complaint of an acute loss of weight within 1 week, vomiting, and disorientation including stumbling, discoordination, circling, wobbling, head tilting, and difficulties in standing. At presentation, the patient had a body condition score of 1/9 and weighed 2.6 kg. Blood examination revealed leukocytosis, anemia, and hypoproteinemia. Abdominal radiography revealed severely decreased serosal details. A massive gas silhouette observed in the peritoneal and retroperitoneal cavities, was diagnosed as abdominal free gas. Abdominal ultrasound showed an accumulation of moderately anechoic fluid mixed with gas and cyst-like capsules around the left kidney. Left partial ureteral obstruction and dilation were also observed. Computed tomography (CT) was performed without sedatives or anesthetic drugs. The findings showed severe inflammatory changes in the peritoneum and a loss of the normal inner structure in the left kidney. A pyelogram of the left kidney was not observed after injection of the contrast material. Diffuse fat stranding and free gas observed in the mesentery of the entire abdominal cavity and around the left kidney were considered septic peritonitis. Urinalysis revealed proteinuria and hematuria. Numerous neutrophils with rod-type bacteria were observed in the ascites. Following diagnostic examinations, the patient was diagnosed with extensive left EPN, including inflammatory ascites and abdominal free gas. Therefore, emergency NU of the nonfunctional left kidney and ruptured ureter and thorough abdominal lavage were conducted. Diffuse inflammation and a nephrolith were observed in the section of the harvested kidney. The nephrolith was composed of 100% calcium oxalate monohydrate. The realtime polymerase chain reaction (RT-PCR) test for feline infectious peritonitis (FIP) was negative. Escherichia coli was detected in the ascites, and antibiotic therapy was administered following the antibiotic sensitivity test. The histological findings from the left kidney and ureter included marked chronic inflammation and fibrosis. The patient was discharged 4 days after surgery. During the 8-month follow-up period, the patient's condition improved. Discussion: This was a unique case of EPN in a nondiabetic cat and the first reported case of EPN with a ruptured ureter, including abdominal free gas, inflammatory ascites, and peritonitis. This patient had a bacterial urinary tract infection with E. coli, which is the most frequently isolated pathogen in humans. This gas-forming bacteria produced a massive amount of gas and inflammation that were considered to have ruptured the urinary tract, so that the gas was released into the abdomen. This case corresponded to class 3B, with two risk factors according to the human EPN classification system. Direct NU and abdominal lavage were performed as emergency surgeries. The patient stabilized gradually and showed a good prognosis. Immediate surgical intervention is recommended in animal patients showing the extensive EPN stage.

Cecal dilatation and distention is an important disorder in early lactation dairy cows, however, reports describing the anatomical pathology findings of this condition are scarce in the literature. Etiopathogenesis of cecal dilatation and distention is often attributed to high concentrate feeds, but there is also evidence of myoelectrical dysfunction contributing to its occurrence. Diagnosis is often made based on physical exam findings, with the contribution of ancillary exams. This paper aims to describe a case of cecal dilatation with clinical, laboratorial and pathology findings of a 5-month-old Holstein calf that presented abdominal distension, positive succussion of the right flank and mild dehydration. Clinical pathology findings included neutrophilic leukocytosis with regenerative left shift and elevated ruminal chloride. Ultrasonographic examination of the right abdomen showed distended and hypomotile intestinal loops. Despite that, due to the patient’s age, which prevented rectal palpation, and lack of some characteristic clinical and clinical pathology findings, diagnosis was only possible post mortem. Macroscopical and microscopical findings demonstrated cecum dilatation with edema, hemorrhage and thrombi. Despite being well known by large animal clinics, anatomical pathologists must be aware of this condition.

Background: The ingestion of foreign bodies in parrots has already been described and associated with the curious behaviorof the birds or with stressful conditions. Foreign bodies in the gastrointestinal tract are usually diagnosed through clinicalsigns, laboratory tests, and radiographic findings in the historical data. Foreign bodies are usually metallic and can lodgein any segment of the gastrointestinal tract, commonly found in the proventricle and gizzard. This study investigated acase of necrotizing hepatitis due to a foreign body in Ara ararauna (Linnaeus, 1758).Case: An approximately 9-month-old specimen of caninde macaw, had sudden death and was referred for autopsy. Themacroscopic examination revealed a fibrous, thick, reddish membrane involving the left hepatic lobe and partially the gizzard in continuity with the peritoneum. Inside the capsule, the liver had a friable and necrotic appearance and the gizzardhad a focal perforation area containing a foreign body (gavage tube feeding). We performed the histopathological examination of the liver and gizzard and observed that the membrane surrounding the liver and partially the gizzard had a chronicinflammatory process with a marked proliferation of fibrous tissue and fibrin deposition. The hepatic parenchyma of theleft lobe showed diffuse and marked necrosis, with signs of ischemic necrosis. In the region of transmural perforation ofthe gizzard, the mucosa showed a focal area of extensive necrosis accompanied by the presence of intralesional bacteria.The lesions observed are attributed to the perforation of the organs by the foreign body. It is not known whether the birdingested the object accidently during food handling as a young or due to the curious behavior of the bird or even the stressit may have been exposed to. The post mortem examination revealed localized peritonitis...

Salmonellosis is a bacterial disease that affects several domestic animal species, and is commonly diagnosed in cattle, horses, and pigs. This study aimed to describe the epidemiological and pathological findings of eleven cases of enteric salmonellosis and two cases of salmonellosis with pulmonary involvement in cattle in Rio Grande do Sul State, Brazil. Clinical signs included fever, yellow diarrhea, sometimes with blood streaks, and dyspnea, with a clinical course ranging from 1 to 30 days. Eight cases occurred as outbreaks, whereas five cases occurred individually. Risk factors included inadequate handling practices, such as overcrowded facilities and comorbidities, including anaplasmosis. The main gross finding of the enteric presentation was fibrinonecrotic enterocolitis, occasionally associated with button ulcers, mesenteric lymphadenomegaly, splenomegaly, cholecystitis and hepatomegaly. In addition, one steer with a chronic clinical progression presented severe segmental thickening of the ileum, associated with intestinal rupture and peritonitis. In the respiratory system, the main findings were reddened, non-collapsed lungs, with multifocal areas of atelectasis. The main microscopic findings were observed in the small and large intestines, and these were characterized by severe necrosis and mucosal ulceration, associated with marked inflammatory infiltrate of neutrophils and fibrin deposition intermixed by rod-shaped bacterial aggregates, and fibrosis, as well as interstitial pneumonia. Seven cases yielded positive bacterial cultures for Salmonella spp. and three serovars, namely Typhimurium, Dublin, and Panama were identified. All cases exhibited immunolabeling for Salmonella spp. using immunohistochemistry.(AU)


Salmonelose é uma doença bacteriana que afeta inúmeras espécies animais, especialmente os bovinos, os equinos e os suínos. O presente estudo teve como objetivo descrever os aspectos epidemiológicos e patológicos de onze casos de salmonelose entérica e dois de salmonelose pulmonar em bovinos no estado do Rio Grande do Sul, Brasil. Os sinais clínicos incluíram febre, diarreia amarelada, por vezes com estrias de sangue, anorexia, perda de peso e dispneia, com curso clínico que variou de um a 30 dias. Em oito casos, a doença ocorreu em forma de surtos e cinco foram individuais. Identificou-se fatores de risco relacionados ao manejo inadequado com os bovinos, como alta lotação, além de comorbidades associadas, como anaplasmose. Os principais achados macroscópicos da forma entérica consistiram em enterocolite fibrinonecrótica, por vezes associada a formação de úlceras botonosas, linfonodos mesentéricos e baço aumentados, colecistite e hepatomegalia. Ainda, um bovino com quadro clínico crônico apresentou acentuado espessamento segmentar da parede do íleo associado a ruptura intestinal e peritonite. Na forma respiratória, os principais achados incluíram pulmões não colabados, avermelhados, com áreas multifocais de atelectasia. Os principais achados microscópicos foram observados no intestino delgado e grosso e foram caracterizados por acentuada necrose e ulceração da mucosa, associada a acentuado infiltrado inflamatório de neutrófilos e deposição de fibrina entremeada por agregados bacterianos cocobacilares e fibrose, além de pneumonia intersticial. Sete casos foram positivos para Salmonella sp. no cultivo bacteriano, com identificação dos sorovares Typhimurium, Dublin e Panama. Ao exame imuno-histoquímico para Salmonella sp. todos os casos apresentaram marcação positiva nos órgãos avaliados.(AU)

Feline infectious peritonitis (FIP) is one of the most prevalent viral diseases of wild and domestic cats. Despite of its multisystemic character, cutaneous lesions of FIP have been rarely described. A skin biopsy from a 14-month-old maleneutered domestic shorthaired cat with a slightly raised, 5 mm in diameter ulcer on the dorsal cervical area and apresumptive clinical diagnosis of FIP was submitted for histological examination. Histological changes consisted of ulcerative dermatitis with perivascular, periadnexal, and interstitial accumulations of neutrophils, macrophages, lymphocytes, and plasma cells with areas of vasculitis. Immunohistochemistry for feline coronavirus revealed intralesional clusters of antigen within macrophages. FIP should be considered in cases of papular to nodular or ulcerative skin lesions in cats when occurring in conjunction with clinical signs of systemic disease consistent with FIP.

Purpose: Comparing survival rates of rats subjected to spleen procedures after fecal peritonitis induction. Assessing changes in TCD4 and CD8 lymphocyte rates before and after the procedures. Correlating animal survival with CD4 and CD8 lymphocytes. Methods: Thirty male Wistar rats were distributed into 3 groups of ten: spleen manipulation (SM); total splenectomy (TS); subtotal splenectomy with preservation of the inferior pole (IP). Rats were subjected to surgical procedure depending on the group. Seven days after surgery they underwent induction of peritonitis and survival time was recorded. All animals were subjected to two blood collections: before surgery and 70 days after it for TCD4/TCD8 lymphocyte counting. Results: Mean survival time was longer in the IP and SM groups and shorter in the TS group; there was significant difference between them. The comparison of the median number of CD4 did not present changes, whereas the comparison of the median number of CD8 decreased in the SM and IP groups. The correlation between the median number of TCD4 and TCD8 lymphocytes and the animals survival was not significant. Conclusion: The maintenance of splenic tissue contributed to increase the survival of rats and there was a change in the number of TCD8 lymphocytes.(AU)

An 11-year (2007-2018) survey of epidemiological, clinical and pathological findings of horses with primary gastric rupture (PGR) was conducted. Twenty horses presented PGR, nine (45%) horses were clinically evaluated, eleven (55%) were sent dead, and all animals were necropsied. PGR contributed to a prevalence of 0.31% (9/2,868) of all equid attendances, 1.83% (9/491) of colic cases, and 4.1% (20/487) of all equid necropsies. Highly fermentable feed (n=7), gastric impaction (n=4), and perforating gastric ulcer (n=1) were the main causes of PGR; whilst eight horses presented idiopathic gastric rupture. Clinically evaluated horses were tachycardic, tachypneic, febrile, dehydrated, with increased abdominal tension, abnormal mucous membranes and reduced to absent intestinal borborygmi. Improper dietary management, such as the ingestion of low-quality roughage and highly fermentable feedstuffs were detected as the main factors associated with PGR in Midwestern Brazil. It is important to raise awareness in horse owners about proper feed management to minimize PGR.(AU)


Foi realizado um levantamento de 11 anos (2007-2018) dos achados epidemiológicos, clínicos e patológicos de equinos com ruptura gástrica primária (RGP). Vinte equinos apresentaram RGP, dos quais nove (45%) foram avaliados clinicamente e 11 (55%) foram enviados mortos, sendo todos os animais necropsiados. A RGP contribuiu com prevalência de 0,31% de todos os atendimentos de equídeos (9/2.868), 1,83% (9/491) dos casos de cólica, e 4,1% (20/487) das necropsias em equídeos. Alimentos altamente fermentáveis (n=7), compactação gástrica (n=4) e perfuração de úlcera gástrica (n=1) foram as principais causas de RGP, enquanto oito equinos tiveram ruptura gástrica idiopática. Os equinos avaliados clinicamente apresentaram-se taquicárdicos, taquipneicos, febris, desidratados, com mucosas anormais, aumento da tensão abdominal e motilidade intestinal reduzida. O manejo inadequado da dieta, como a ingestão de forragens de baixa qualidade e alimentos altamente fermentáveis, foi o principal fator de risco associado à RGP no Centro-Oeste do Brasil. É importante aumentar a conscientização dos proprietários de equinos sobre o manejo alimentar adequado para minimizar a RGP.(AU)

O objetivo deste estudo foi avaliar simultaneamente biomarcadores no sangue e no líquido peritoneal (LP) de bovinos com enfermidades intestinais (GI n=14) e reticulites traumáticas (GII n=13). O exame clínico e a coleta de sangue e de LP foram realizadas e, posteriormente, análise física e citológica do LP, bem como as determinações bioquímicas no sangue e no LP. Empregou-se a análise de variância ao nível de 5% de probabilidade comparando os grupos e comparando o sangue e o LP. Em ambos os grupos foram evidenciados sinais de apatia, desidratação e hipomotilidade reticuloruminal, porém os animais do GI apresentaram alterações clínicas mais expressivas. À análise citológica do LP No sangue as concentrações de PT, globulina, colesterol e GGT foram superiores no GII (P<0,05), e a relação A/G foi maior no GI (P<0,05). No LP a albumina e a CK foram superiores no GI (P<0,05). Na comparação entre o sangue e LP, destacou-se o aumento significativo do lactato L no LP de ambos os grupos (P<0,05), caracterizando a gravidade das alterações presentes na cavidade abdominal. Recomendase a avaliação simultânea no sangue e no LP do lactato L como informação de auxílio diagnóstico e prognóstico das enfermidades digestivas dos bovinos.


The objective of this study was to simultaneously evaluate biomarkers in the blood and peritoneal fluid (PF) of cattle with intestinal diseases (GI n=14) and traumatic reticulitis (GII n=13). A clinical examination and blood collection and PF were performed and subsequently, physical and cytological analysis of PF, as well as biochemical determinations in blood and PF. The analysis of variance was used at a 5% probability level comparing the groups and comparing blood and PF. In both groups, signs of apathy, dehydration and reticuloruminal hypomotility were evidenced, but the GI animals presented more expressive clinical alterations. In the cytological analysis of PF, a predominance of polymorfhonuclear was observed in both groups. Blood TP, globulin, cholesterol and GGT concentrations were higher in GII (P<0.05), and the A/G ratio was higher in GI (P <0.05). In PF, albumin and CK were higher in GI (P<0.05). In the comparison between blood and PF, the significant increase of L-lactate in the PF of both groups (P<0.05) was observed, characterizing the severity of the alterations present in the abdominal cavity. It is recommended the simultaneous evaluation of L-lactate in the blood and PF, as a tool for diagnosis and prognosis of bovine digestive diseases.

Feline Infectious Peritonitis (FIP) is a progressive and fatal disease in domestic and wild cats, caused by Feline Infectious Peritonitis Virus (FIPV). The disease is characterized by an immunomediated reaction against the virus in various organs. This work described a case report of fibrinous epicarditis caused by FIPV. A male cat, three years old, died and was received to be necropsied. Grossly, soft, multifocal to coalescing, whitish fibrinous exudate, measuring up the 2 centimeters of thickness, was observed in the epicardium, mostly at the apex of the heart. Microscopically, severe, multifocal to coalescing inflammatory infiltrate was observed in the epicardium, composed mainly by macrophages, plasmocytes and lymphocytes, associated with fibrin deposition. Immunohistochemistry was performed for FIPV and was positive in the areas of inflammation in the epicardium. To the author´s knowledge, this is the second report of epicarditis due to FIPV in a cat. Therefore, epicarditis should be considered a differential diagnosis of cardiac diseases in Feline Medicine.(AU)


A Peritonite Infecciosa Felina (PIF) é uma doença progressiva e fatal de felinos domésticos e selvagens, causada pelo vírus da Peritonite Infecciosa Felina (FIPV). A doença é caracterizada por uma reação imunomediada contra o vírus em vários órgãos. Este trabalho descreveu um relato de caso de epicardite fibrinosa causada pelo FPIV. Um gato macho, com três anos de idade, veio a óbito e foi recebido para necropsia. Macroscopicamente, foi observado exsudato fibrinoso esbranquiçado, friável, multifocal, medindo até 2 centímetros de espessura, no epicárdio, principalmente no ápice cardíaco. Microscopicamente, foi observado no epicárdio um infiltrado inflamatório misto, multifocal, composto por macrófagos, plasmócitos e linfócitos, associado a deposição de fibrina. A imuno-histoquímica foi positiva para o FIPV nas áreas de inflamação no epicárdio. Os autores descrevem o segundo relato de caso na literatura científica de epicardite causada pelo FIPV em um gato. Portanto, a epicardite deve ser considerada como diagnóstico diferencial em doenças cardíacas em Medicina Felina.(AU)

In the comparison between blood and PF, the significant increase of L-lactate in the PF of both groups (P<0.05) was observed, characterizing the severity of the alterations present in the abdominal cavity. It is recommended the simultaneous evaluation of L-lactate in the blood and PF, as a tool for diagnosis and prognosis of bovine digestive diseases.(AU)

Resumo

Feline Infectious Peritonitis (FIP) is a progressive and fatal disease in domestic and wild cats, caused by Feline Infectious Peritonitis Virus (FIPV). The disease is characterized by an immunomediated reaction against the virus in various organs. This work described a case report of fibrinous epicarditis caused by FIPV. A male cat, three years old, died and was received to be necropsied. Grossly, soft, multifocal to coalescing, whitish fibrinous exudate, measuring up the 2 centimeters of thickness, was observed in the epicardium, mostly at the apex of the heart. Microscopically, severe, multifocal to coalescing inflammatory infiltrate was observed in the epicardium, composed mainly by macrophages, plasmocytes and lymphocytes, associated with fibrin deposition. Immunohistochemistry was performed for FIPV and was positive in the areas of inflammation in the epicardium. To the author´s knowledge, this is the second report of epicarditis due to FIPV in a cat. Therefore, epicarditis should be considered a differential diagnosis of cardiac diseases in Feline Medicine.(AU)


A Peritonite Infecciosa Felina (PIF) é uma doença progressiva e fatal de felinos domésticos e selvagens, causada pelo vírus da Peritonite Infecciosa Felina (FIPV). A doença é caracterizada por uma reação imunomediada contra o vírus em vários órgãos. Este trabalho descreveu um relato de caso de epicardite fibrinosa causada pelo FPIV. Um gato macho, com três anos de idade, veio a óbito e foi recebido para necropsia. Macroscopicamente, foi observado exsudato fibrinoso esbranquiçado, friável, multifocal, medindo até 2 centímetros de espessura, no epicárdio, principalmente no ápice cardíaco. Microscopicamente, foi observado no epicárdio um infiltrado inflamatório misto, multifocal, composto por macrófagos, plasmócitos e linfócitos, associado a deposição de fibrina. A imuno-histoquímica foi positiva para o FIPV nas áreas de inflamação no epicárdio. Os autores descrevem o segundo relato de caso na literatura científica de epicardite causada pelo FIPV em um gato. Portanto, a epicardite deve ser considerada como diagnóstico diferencial em doenças cardíacas em Medicina Felina.(AU)

Resumo

Nocardiose é causada por bactérias do gênero Nocardia do subgrupo Actinomycetos, que são Gram-positivas aeróbicas, filamentosas e podem apresentar ramificações. O diagnóstico baseia-se na presença de lesão inflamatória, com o microrganismo morfologicamente compatível, associada ao isolamento e à identificação microbiológica e molecular. Este trabalho tem por objetivo relatar um caso de nocardiose em canino, que desenvolveu inflamação piogranulomatosa peritoneal seis meses após ovariossalpingo-histerectomia. O animal apresentava hipertermia, distensão abdominal, taquipneia, polidipsia, hiporexia, mucosas hipocoradas e fezes pastosas. Os achados laboratoriais evidenciaram anemia leve e leucocitose por neutrofilia com desvio à esquerda e hipoalbuminemia. Uma massa na região mesogástrica e efusão peritoneal foram evidenciadas por meio da ultrassonografia abdominal. O líquido foi classificado como exsudato piogranulomatoso, e o animal submetido à laparotomia exploratória para lavagem abdominal e remoção da massa. Após procedimentos terapêuticos, ocorreu piora clínica e óbito. Peritonite piogranulomatosa foi a principal alteração anatomopatológica a qual foi associada à Nocardia spp. Molecularmente, a espécie isolada se aproxima da N. concava, por meio da análise filogenética. Essa espécie já foi descrita como causa de infecção em humanos na Ásia, no entanto não há registros na literatura na espécie canina, sendo este o primeiro relato.(AU)


Nocardiosis is caused by an aerobic, gram-positive, ramificated and filamentous bacteria of the Nocardia genus, subgroup Actinomycetos. The diagnosis is based on the presence of the inflammatory lesions with the morphologically compatible microorganism associated with microbiological and molecular isolation and identification. The objective of this work is to report a case of nocardiosis in a canine that developed peritoneal pyogranulomatous inflammation six months after ovariosalpingohisterectomy. The animal had hyperthermia, abdominal distention, tachypnea, polydipsia, hyporexia, hypocorous mucosae and pasty feces. The laboratory findings revealed mild anemia and leukocytosis due to neutrophilia with left deviation and hypoalbuminemia. A mass in the mesogastric region and peritoneal effusion were evidenced by abdominal ultrasonography. The fluid was classified as pyogranulomatous exudate and the animal underwent exploratory laparotomy for abdominal lavage and mass removal. Despite the therapeutic procedures and clinical alterations the dog died. Piogranulomatous peritonitis was the main anatomopathological alteration which was associated with Nocardia spp. Molecularly, the isolated species approaches the N. concava species through phylogenetic analysis. This specie was described as a cause of infection in humans in Asia; however, there are no records in literature on the canine species, being this the first report.(AU)

Splenic abscess is an uncommon condition in humans and animals. The present report describes a rare case of suppurative splenitis in a 14-month-old filly, presented with signs of mild colic, depression and hyporexia. After clinical and laboratorial evaluation, a suppurative process of undetermined location was suspected. Medical therapy and supportive care were initiated, general condition has degraded in few days, and a paracentesis was performed diagnosing peritonitis. Given the poor prognosis, euthanasia was elected. At necropsy, multiple splenic abscess and diffuse peritonitis were identified. The etiology was not determined.

Purpose: To investigate cardiac changes in young rats, whose mothers underwent autogenic fecal peritonitis, during organogenesis phase and to evaluate the role of intravenous administration of moxifloxacin and dexamethasone in preventing infection-related cardiac changes. Methods: A prospective histomorphometric study was performed on 29 hearts of Wistar four-month old rats. Animals were divided into three groups: Negative Control Group (NCG) included 9 subjects from healthy mothers; Positive Control Group (PCG) included 10 subjects from mothers with fecal peritonitis (intra-abdominal injection of 10% autogenic fecal suspension in the gestational period) and did not receive any treatment; and Intervention Group (IG), with 10 animals whose infected mothers received moxifloxacin and dexamethasone treatment 24 hours after induction of fecal peritonitis. Results: Nuclear count was higher in the IG group as compared to PCG (p = 0.0016) and in NCG as compared to PCG (p = 0.0380). There was no significant difference in nuclear counts between NCG and IG. Conclusion: Induced autogenic fecal peritonitis in pregnant Wistar rats determined myocardial changes in young rats that could be avoided by the early administration of intravenous moxifloxacin and dexamethasone.(AU)
