3-Hydroxy-3-methylglutaric aciduria (OMIM 246450) is an autosomal recessive inborn error of the final step of leucine catabolic and ketogenic pathways, caused by deficiency of the enzyme 3-hydroxy-3-methylglutaryl CoA lyase (HL, HMGCL, EC 4.1.3.4). Clinically, deficiency of the enzyme results in metabolic acidosis, hyperammonemia, and infantile hypoketotic hypoglycaemia usually presenting during the first year of life with vomiting, lethargy, hypotonia, and sometimes with respiratory distress and coma. HL deficiency is relatively common in Arabic populations but seems to be rare in Europe. Our recent experience suggests that HL deficiency is the most frequent organic aciduria in the Portuguese population. We herein report on the molecular study of the HMGCL gene in 11 cases originated from the Northern area of Portugal. We detected the E37X (c.109G > T) mutation, in 84.1% of the alleles, one allele carried the V168fs(-2) (504_505delCT) and other allele the novel D204N (c.610G > A) mutation. The mutation of the last allele remained unidentified. The relatively high frequency of the "common" HMGCL Portuguese mutation makes useful the development of a rapid and specific molecular confirmation of new cases with HL deficiency in our country.

A 21-month-old, male Pembroke Welsh corgi was referred for investigation of respiratory distress and progressive lethargy. Cardiac evaluation revealed a grade 4 pansystolic murmur over the left and right heart base. A heart murmur, dyspnoea, cyanosis, prolonged capillary refill time and ascites led to the tentative diagnosis of a cardiac malformation with a right-to-left shunt, with likely additional pulmonary disease. Pulmonary hypertension became evident during echocardiography, when the estimated systolic pulmonary artery pressure was over 70 mmHg. Angiography revealed abnormal pulmonary vascular markings consistent with pulmonary hypertension and a small right-to-left shunting patent ductus arteriosus (PDA). The diagnosis of PDA was confirmed at postmortem examination. Histology of the pulmonary arteries showed lesions of plexogenic pulmonary arteriopathy. The question of whether both conditions were separate or part of the same clinical syndrome is discussed in this report.

A male fennec fox (Fennecus zerda) kit was examined for lethargy, inappetence, and weight loss. Clinical findings included respiratory distress, a gallop rhythm, and retinochoroiditis. Radiography indicated pleural effusion and cardiomegaly. Echocardiographic findings included left ventricular dilatation, low left ventricular ejection fraction, and atrioventricular valvular regurgitation. Necropsy findings were compatible with a diagnosis of congestive heart failure caused by myocarditis. Histopathology showed a disseminated infection with Toxoplasma gondii causing myocarditis, skeletal polymyositis, gastrointestinal myositis, and panuveitis. Toxoplasma-induced myocarditis should be included in the differential diagnosis of heart failure and retinochoroiditis in the fennec fox.

Four groups comprising 16 broiler birds each were given benzalkonium chloride (BC) at 100, 300, 500 and 700 ppm in drinking water for 40 days and one group of 16 birds (control) was kept on plain water. Clinical signs in higher dose groups were respiratory distress, drooling of saliva, difficulty in deglutition, inappetence, apathy, lethargy and loss of body weight. Better body weight gain was recorded in 100 ppm dose rate. At 300 ppm, no significant body weight variation was recorded, whereas, at 500 and 700 ppm dose rates, significantly poor body weight gain was recorded. Major pathological changes were seen in 500 and 700 ppm groups, which exhibited formation of yellow diphtheritic plaques in the buccal cavity, swollen and pale commissures of beak and shortening of tongue. Minute necrotic and ulcerative foci were seen in oesophagus and crop. Hyperplastic and hypertrophic alterations were seen in mucosa of the upper digestive tract. Crop of 300 ppm group revealed formation of well developed epithelial nest with pseudoepitheliomatous hyperplasia at the margin of the lesion. Serum alanine transaminase, urea and uric acid in 500 and 700 ppm groups were elevated whereas no significant variations were observed in the 100 and 300 ppm groups. BC could enhance performance of broiler birds at 100 ppm dose rate. It should not be used beyond 300 ppm.

I report the case of an infant girl who was exposed to lithium during gestation and her follow-up at the age of 1 year. She presented with transient neurodevelopmental deficits including lethargy, hypotonia, and poor oral feeding ability in the neonatal period. She required supportive treatment and made gradual improvement in neurologic functioning. On examination at the age of 1 year, physical findings and psychomotor development were normal. The English literature from 1978 to 2004 is reviewed. A total of 30 patients who were exposed to lithium during gestation with adequate clinical description were identified. A significant number of these babies presented with neurodevelopmental deficits and depressed neurological status including hypotonia, respiratory distress syndrome, cyanosis, lethargy, and weak suck and Moro reflexes in the neonatal period. The majority of these abnormalities resolved and most babies made full recovery. Other abnormalities were structural as well as functional involvement of the cardiovascular system, macrosomia, prematurity, jaundice, diabetes insipidus, and involvement of the thyroid gland. While the use of lithium during pregnancy does not appear to significantly increase the risk of congenital anomalies, it is frequently associated with perinatal complications and reversible neonatal toxicity. Suggested guidelines for appropriate monitoring of infants and breast-feeding of exposed babies are presented. In addition, prenatal surveillance of women with bipolar disorders who are being treated with lithium is briefly discussed.

Seven captive eastern box turtles (Terrapene carolina carolina) from a large collection of North American chelonians in North Carolina became acutely ill in the fall of 2002. Five of the turtles died. Clinical signs included cutaneous abscessation, oral ulceration or abscessation (or both), respiratory distress, anorexia, and lethargy. The predominant postmortem lesion was fibrinoid vasculitis of various organs, including skin, mucous membranes, lungs, and liver. No inclusion bodies were detected by histopathology or electron microscopy of formalin-fixed tissue. An iridovirus was isolated from tissues obtained postmortem from two of the box turtles that died. The virus was characterized by electron microscopy, polymerase chain reaction, and sequence analysis of a portion of the major capsid protein as a member of the genus Ranavirus.

A 3-month-old female Arabian horse was evaluated because of fever, respiratory distress, lethargy, and decreased appetite of 5 days' duration. Pleural effusion was diagnosed on the basis of ultrasonographic and radiographic examinations. Cytologic examination of pleural fluid collected via thoracocentesis revealed septic inflammation; bacteriologic culture of a sample of that fluid yielded Rhodococcus equi. A large intra-abdominal mass adjacent to the body wall was identified ultrasonographically. A specimen of the mass was collected via aspiration; the specimen was identified cytologically as purulent exudate that contained large numbers of rod-shaped bacteria, which confirmed abdominal abscess formation. Bacteriologic culture of a sample of the exudate also yielded R. equi. The foal was treated with azithromycin (10 mg/kg [4.5 mg/lb], PO, q 24 h for 5 days then q 48 h) and rifampin (5 mg/kg [2.3 mg/lb], PO, q 12 h) for 8 weeks and metronidazole (15 mg/kg [6.8 mg/lb], PO, q 8 h) for 3 weeks. Clinically, the foal responded to antimicrobial treatment within 2 weeks. At 8 weeks after the initial evaluation, ultrasonographic examination of the foal revealed resolution of the pleural effusion and abdominal abscess. In foals, R. equi infection typically results in pyogranulomatous pneumonia, and pleural effusion is an uncommon clinical sign. The combination of azithromycin and rifampin appears to be an effective treatment for R. equi infection in foals.

In a population of spotted hyenas (Crocuta crocuta) monitored between 1996 and 2005 in the Ngorongoro Crater, Tanzania, 16 individuals from five of eight social groups displayed clinical signs of an infection, including severe unilateral swelling of the head followed by abscess formation at the mandibular angle, respiratory distress, mild ataxia, and lethargy. Two (12.5%) of these 16 individuals died within days of developing signs. Clinical signs in hyenas were first noted in 2001, and most cases occurred between September 2002 and February 2003, suggesting an outbreak of infection during this period. Histopathological examination of internal organs from one hyena that died with signs revealed morphological changes consistent with severe bacterial infection. Phenotypic examination and phylogenetic analysis of the 16S rRNA gene of the causative agent of infection revealed a Lancefield group C Streptococcus with a high level of homology to S. equi subsp. ruminatorum, a subspecies of S. equi recently described in domestic sheep (Ovis aries) and goats (Capra hircus) with mastitis in Spain. Strains similar to this bacterium were also isolated from two hyenas without obvious clinical signs, suggesting that hyenas may be 'carriers' of this bacterium, and from a sympatric Burchell's zebra (Equus burchelli), a herbivore species often consumed by hyenas. To our knowledge this is the first report of a Streptococcus infection in these two wildlife species. The high genetic similarity between the hyena and zebra isolates indicates that inter-specific transmission may occur, possibly when hyenas consume infected zebra carcasses.

Clinical observations of Babesia canis infection in 63 dogs during a 1-year period are summarised, demonstrating the pathogenicity of the Babesia strain endemic in Hungary. Most patients had babesiosis in the spring and autumn, correlating with the seasonal activity of ticks. Male animals appeared in higher numbers, probably due to an overrepresentation of outdoor dogs. Uncomplicated babesiosis was diagnosed in 32 cases. The disease affected dogs of any age in this study. Symptoms were similar to those published from other parts of the world: lethargy, fever, splenomegaly, pallor, icterus, haemoglobinuria and presence of ticks were the most common observations. Thrombocytopenia, lymphopenia and neutropenia were frequent haemogram changes. Imidocarb appeared to be highly effective in eliminating the Babesia infection. Thirty-one animals demonstrated babesiosis with complications. Most Rottweilers (7/9) developed complicated disease. Old age was a risk factor for multiple complications. Multiple organ manifestations had poor prognosis. Hepatopathy (44%), pancreatitis (33%), acute renal failure (ARF; 31%) and disseminated intravascular coagulation (DIC; 24%) were frequent complications, while immune-mediated haemolytic anaemia (IMHA; 10%), acute respiratory distress syndrome (ARDS; 6%) and cerebral babesiosis (3%) were rarely observed. There was a significant difference between the mean age of dogs having uncomplicated disease, babesiosis with a single complication and babesiosis with multiple complications (3.4, 4.8 and 8.6 years, respectively, p < 0.001). The recovery rate (78, 68 and 25%, respectively, p = 0.005) and mortality rate (3, 21 and 67%, respectively, p < 0.001) also tended to differ significantly in these groups. Systemic inflammatory response syndrome (SIRS) and DIC are two possible pathways leading to multiple organ dysfunction syndrome (MODS) in babesiosis. DIC was found to predict MODS more sensitively in this study than SIRS: there were 6 animals developing MODS out of 11 identified with DIC, while only 5 dogs developed MODS out of 22 having SIRS.

A male mallard duck (Anas platyrhynchos) presented for examination for acute respiratory distress and lethargy. The duck had experienced recurrent episodes of respiratory distress since being attacked by a raccoon the previous year, resulting in neck lacerations. Diagnostic tests, including a complete blood count, plasma biochemical analysis, radiography, and tracheoscopy, revealed a collapsed trachea. Surgical correction of the collapsed tracheal segment resulted in resection of 9% of the total tracheal length and subsequent anastomosis. Tracheoscopy performed 2 and 3 months after surgery revealed a healthy mucosa, minimal reduction of the tracheal lumen in the area of anastomosis, and minimal suture granuloma formation.
