Neospora caninum is an apicomplexan protozoan responsible for abortion in ruminants. The present study aimed to diagnose an abortion from an Anglo Nubian goat from a dairy herd located in Buenos Aires province, Argentina. The goat delivered a fetus of approximately 3 months gestation that was studied by indirect fluorescent antibody test (IFAT), Immunoblot (IB), histopathology (HP), immunohistochemistry (IHC), and molecular assays (PCR, sequencing and microsatellite genotyping). Interferon gamma knock-out mice were inoculated with a pool of tissues for isolation attempts...

Effacement of normal lung parenchyma by cavities is an important sequela of pulmonary tuberculosis. Despite its clinical significance, the pathogenesis of tuberculous cavitation is poorly understood, with controversy as to whether the fundamental mechanism involves matrix depletion, lipid pneumonia, or mechanical factors. In this study, a repetitive aerosol infection model using Mycobacterium tuberculosis was used to generate cavities in 20 New Zealand White rabbits. Serial computed tomography was performed to monitor cavity progression over 14 weeks...

Anti-neutrophil cytoplasmic antibody (ANCA) -associated vasculitis (AAV) and cryoglobulinemic vasculitis (CV) rarely coexist. An 83-year-old woman was admitted with rapidly progressive renal failure, gastrointestinal hemorrhage and purpura with myeloperoxidase (MPO) -ANCA positivity and cryoglobulinemia. Despite intensive immunosuppressive treatment, she died of aspergillus pneumonia. Autopsy revealed necrotizing crescentic glomerulitis in the majority of the glomeruli, accompanied by partially membranoproliferative-like glomerular changes...

BACKGROUND: Toxoplasma gondii (T. gondii) is an intracellular protozoan parasite that can infect warm-blooded animals including humans. New World monkeys, such as squirrel monkeys, are more susceptible to T. gondii than Old World monkeys, often developing fatal disease. METHODS: In this study, seven of thirteen dead squirrel monkeys at Seoul Grand Park were tested to find the cause of sudden death. RESULTS: The main histopathological findings included interstitial pneumonia, necrotizing hepatitis, and splenitis...

Chromobacterium violaceum is a rare, potentially serious pathogen. Most clinicians have no experience with its clinical appearance or treatment. We describe a case of a child presenting with necrotizing pneumonia caused by C. violaceum . We describe case complexities, including the need for a multidisciplinary approach to diagnosis and treatment.

Methicillin-resistant Staphylococcus aureus (MRSA) in prisons can result in serious morbidity and death. We reviewed rates and risk factors for MRSA infection in custody, searching Medline, EMBASE, and CINAHL databases. Between 1997 and 2015, 17 studies reported MRSA skin and soft tissue infections (SSTIs), with four case reports of MRSA non-SSTI (necrotizing pneumonias, brain abscess, and epiduritis). Significant associations with MRSA SSTI were found: MRSA colonization, previous skin infection, sharing soap or personal items, SSTI presenting as an abscess or furuncle, younger age, non-Caucasian, overweight, communal laundering, infrequent handwashing, lower hygiene score...

Case: Necrotizing enterocolitis (NEC) caused by Clostridium butyricum is common in neonates; however, a case of NEC in adults has not been previously reported. An 84-year-old Japanese man developed C. butyricum -related NEC during hospitalization for treatment of stab wounds to the left side of the neck and lower abdomen, without organ damage, and concomitant pneumonia. Outcome: The patient developed acute onset of emesis accompanied by shock during his admission; partial resection of the small intestine was carried out due to necrosis...

Extracerebral toxoplasmosis, with pulmonary involvement and shock, is a rare form of toxoplasmosis in patients with advanced AIDS. It can mimic pneumocystosis, histoplasmosis, and disseminated tuberculosis, and should be considered in the differential diagnosis of causes of respiratory failure and fulminant disease in this group of individuals, especially in areas where the Toxoplasma gondii infection is highly prevalent and in those without proper use of antimicrobial prophylaxis. We report the case of a 46-year-old male patient who presented to the emergency department with uremia, requiring urgent dialysis...

Human adenovirus (HAdV) is a common respiratory pathogen in children, with no safe and effective treatment currently available. HAdV type 7 (HAdV-7), in particular, causes severe pediatric pneumonia with a high incidence of sequelae and mortality. Clinical data and animal experiments suggest that HAdV-7-induced pneumonia promotes cell necrosis, releasing a large number of inflammatory mediators. In recent years, the high mobility group box-1 (HMGB1) protein, released by necrotic cells, has been shown to play important roles in several viral infections...

We report the case of a 47-year-old man with chronic obstructive pulmonary disease who was referred to our hospital for acute dyspnea. The radiologic findings revealed consolidation with a cavity in the left upper lobe of the lung. Blood/sputum cultures detected Pseudomonas aeruginosa. Despite intensive care, the patient died from respiratory failure. Autopsy revealed multiple small necrotizing cavities that had coalesced. Although P. aeruginosa is a known causative pathogen of community-acquired pneumonia in patients with structural lung disease, the radiologic findings were non-specific...

Methicillin-resistant S taphylococcus aureus (MRSA) was previously considered a purely nosocomial pathogen. However, community-acquired MRSA has recently emerged as an important cause of severe necrotizing community-acquired pneumonia (CA-MRSA) in previously healthy individuals. This new pathogen exhibits antibiotic resistance and is linked to extended hospital stay and higher mortality. CA-MRSA has presented new therapeutic challenges due to high vancomycin treatment failure and lack of specificity of clinical findings...

Cavities occasionally are encountered on thoracic images. Their differential diagnosis is large and includes, among others, various infections, autoimmune conditions, and primary and metastatic malignancies. We offer an algorithmic approach to their evaluation by initially excluding mimics of cavities and then broadly classifying them according to the duration of clinical symptoms and radiographic abnormalities. An acute or subacute process (< 12 weeks) suggests common bacterial and uncommon nocardial and fungal causes of pulmonary abscesses, necrotizing pneumonias, and septic emboli...

OBJECTIVES: The knowledge about pathogens and their antibiotic susceptibility patterns is essential to select an appropriate antibiotic. METHODS: We investigated the microbiological profile in pancreatic and extrapancreatic infections, and antibiotic sensitivity pattern in patients with acute pancreatitis. RESULTS: Of 556 patients with acute pancreatitis, only 189 developed bacterial infection; however, bacteremia was present in 42 patients (7...

Following the introduction of 7-valent pneumococcal vaccine (PCV7), while overall rates of invasive pneumococcal disease and pneumococcal pneumonia in children declined, rates of empyema increased. We examined changes in the incidence of hospitalization for pediatric complicated pneumonia (PCOMP) in Eastern Ontario, Canada, particularly since the introduction of the 13-valent vaccine (PCV13). A retrospective chart review was carried out evaluating previously healthy children admitted with PCOMP, which included empyema, parapneumonic effusion, necrotizing pneumonia, and lung abscess between 2002 and 2015...

BACKGROUND: Cytomegalovirus (CMV) enterocolitis is rare in term neonates. CASE CHARACTERISTICS: A term newborn with persistent pneumonia from birth developed enterocolitis on day 18 of life. OUTCOME: Polymerase chain reaction (PCR) for CMV DNA was positive in urine sample. Antiviral therapy for six weeks resulted in successful treatment without any stricture formation. MESSAGE: CMV enterocolitis should be considered as a differential diagnosis in atypical cases of necrotizing enterocolitis in neonates...

BACKGROUND: Descending necrotizing mediastinitis is a common and progressive polymicrobial infection involving the neck and chest with a high death rate (10 to 40%). From a microbiological point of view, descending necrotizing mediastinitis is sustained by Gram-positive bacteria (43-62%), anaerobes (46-78%), and, rarely, Gram-negative bacteria. Data collected during the Antibiotic Resistance-Istituto Superiore di Sanità project confirmed that Italy is positioned among the countries with the highest levels of resistance in most pathogenic species under surveillance...
