Lung lobe torsion, although rare in cats, can be seen as a sequela to chronic respiratory disease. Clinical signs may include lethargy, coughing, hemoptysis, and respiratory distress. Lung lobe torsion may be diagnosed using radiography, ultrasonography, contrast bronchography, bronchoscopy, or thoracoscopy. Stabilization with fluids, oxygen, and supportive care followed by thoracotomy and lobectomy of the affected lobe(s) are necessary for a successful outcome. Diagnosis and treatment of lung lobe torsion is described in a 12.5-year-old cat with a history of feline asthma.

Abstract Background Bovine respiratory disease (BRD) is the main cause of mortality among 1-to-5 month old calves in Ireland, accounting for approximately one-third of deaths. Despite widespread use of clinical respiratory signs for diagnosing BRD, lung lesions are detected, using thoracic ultrasonography (TUS) or following post-mortem, in calves showing no clinical signs. This highlights the limitation of clinical respiratory signs as a method of detecting sub-clinical BRD. Using 53 purchased artificially-reared male dairy calves, the objectives of this study were to: (i) characterise the BRD incidence detected by clinical respiratory signs and/or TUS, (ii) investigate the association between clinical respiratory signs and lung lesions detected by TUS, and (iii) assess the effect of BRD on pre-weaning growth. Results Clinical BRD (based on Wisconsin clinical respiratory score and/or rectal temperature > 39.6 ºC) was detected in 43 % and sonographic changes (lung lesions) were detected in 64 % of calves from purchase (23 (SD; 6.2) days of age) until weaning, 53 days post-arrival. Calves with clinical BRD were treated. Sixty-one per cent calves affected with clinical BRD had lung lesions 10.5 days (median) before detection of clinical signs. Moderate correlations (rsp 0.70; P < 0.05) were found between cough and severe lung lesions on arrival day, and between rectal temperature > 39.6 ºC and lung lesions ≥ 2 cm2 on day 7 (rsp 0.40; P < 0.05) post-arrival. Mean average daily live weight gain (ADG) of calves from purchase to weaning was 0.75 (SD; 0.10) kg; calves with or without clinical BRD did not differ in ADG (P > 0.05), whereas ADG of those with severe lung lesions (lung lobe completely consolidated or pulmonary emphysema) was 0.12 kg/d less (P < 0.05) than calves without lung lesions. Conclusions Thoracic ultrasonography detected lung consolidation in calves that did not show signs of respiratory disease. The presence of severe lung lesions was associated with reduced pre-weaning growth. These findings emphasise the importance of using TUS in addition to clinical respiratory scoring of calves for an early and accurate detection of clinical and sub-clinical BRD.

During an 18-month oncogenicity study using rats, approximately 10% of the animals developed a form of respiratory distress very similar to that seen in the terminal stages of chronic respiratory disease, commonly associated with Mycoplasma pulmonis infection. Investigation of the lungs of the affected rats revealed not only that they did not have the consolidation usually associated with chronic respiratory disease, but they also appeared macroscopically normal. Further investigation of a number of cases revealed systemic intravascular thrombus formation of the type usually referred to as disseminated intravascular coagulation. Using an antiserum to fibrin we have demonstrated the presence of intravascular fibrin deposits in the lungs of the affected rats and have shown them to be the same as experimentally induced intravascular fibrin deposits induced in rat lungs by the administration of thrombin after blocking the fibrinolytic system. This is the first example of such a phenomenon being recorded in aging rats.

Respiratory disease is common in avian species. Rapid diagnosis and treatment are essential as birds tend to hide clinical signs of illness until disease is advanced and cases can deteriorate rapidly. Risk factors are frequently related to diet and environment, and include hypovitaminosis A and inhaled irritants. Birds presenting with respiratory signs should initially be stabilised with oxygen supplementation and supportive care before further diagnostics are pursued. Work up of these cases includes blood sampling for biochemistry and haematology, imaging including radiography and rigid endoscopy, and culture and polymerase chain reaction testing of respiratory secretions. Chlamydia and aspergillosis are common diagnoses encountered in practice. Treatment includes systemic antimicrobials, non-steroidal anti-inflammatory drugs and inhaled medications administered via nebulisation. Correction of underlying risk factors is also essential for a successful outcome. This article gives an overview of avian respiratory disease and describes a systematic approach to the investigation and treatment of these cases, achievable in general practice.

Previous in vitro studies showed that nanoparticle extract of turmeric, zedoary, and garlic exhibit antibacterial activity against Mycoplasma gallisepticum (M. gallisepticum) which causes chronic respiratory disease (CRD) in chicken. This research aimed to determine the antibacterial activity of nanoparticles of Curcuma longa, Curcuma zedoaria, and Allium sativum extract to CRD infected chicken. In vivo test of antibacterial activity of turmeric, zedoary, and garlic nanoparticle in combination was conducted on chicken infected by M. gallisepticum and Escherichia coli (E.coli). Antibiotic control used was enrofloxacin. As many as 75 chickens were divided into 5 groups containing 15 chickens each. Group one consisted of healthy chickens (positive control); group two consisted of chickens that have been inoculated by bacteria (negative control); group three (treatment) were chickens inoculated by bacterium and given extract nanoparticle combination on day 7 of infection for 7 days; group four (prevention) were chickens inoculated by bacterium and given combination of extract nanoparticles on day 5 before infection for 14 days; group five were chickens inoculated with bacterium and given enrofloxacin antibiotics for 7 days. In vivo research results showed increased body weight and performance indicated by improvements in clinical signs, and gross pathology changes. The combination of three extract nanoparticles showed the best activity in controlling CRD in chicken, both as preventive and curative means.

BackgroundNon-communicable respiratory diseases are important contributors to morbidity and mortality in sub-Saharan African countries such as Malawi. AimTo conduct a systematic review of the available literature relating to chronic respiratory disease in Malawi. MethodsWe conducted a systematic protocol-driven literature search of key scientific databases including Scopus and Medline. Papers were independently assessed for eligibility by two authors and included if they reported objective measures (including self-reported standard symptoms) of chronic respiratory disease and were conducted in Malawi. A meta-analysis of available estimates was then conducted. We re-analysed data from three of these studies in a secondary data analysis to allow for between-study comparisons. ResultsOur search identified 393 papers of which 17 (5 involving children and 12 involving adults) met the inclusion criteria. Wheeze was the symptom most frequently reported in children in the community (12.1%), hospital (11.2%) and HIV clinic (8.1%) settings. Cough was the symptom most frequently reported by adults in the community (3–18%). Spirometric abnormalities varied substantially between studies. For example, in adults, airflow obstruction varied between 2.3% and 20% and low forced vital capacity (FVC) varied between 2.7% and 52.8%. ConclusionWe identified a high burden of chronic respiratory symptoms and abnormal spirometry (particularly low FVC) within paediatric and adult populations in Malawi. The estimates for country-wide burden related to this disease were limited by the heterogeneity of the methods used to assess symptoms and spirometry. There is an urgent need to develop a better understanding of the determinants and natural history of non-communicable respiratory disease across the life-course in Malawi.

Intoxication with clozapine in a dog, suspected from history and clinical signs at presentation, was confirmed by demonstration of decreasing serum levels of this drug. Clozapine is a tricyclic dibenzodiazepine used for treatment of human schizophrenia, and clinical signs of intoxication in humans include tachycardia, seizures, muscle fasciculations, agitation, and sialorrhea. This dog showed ptyalism, hyperthermia, tachycardia, and was easily excited by tactile or auditory stimulation. The calculated peak concentration of clozapine in this dog was approximately 6,000 ng/mL, and the elimination half-life (t1/2) was 5 hours. Charcoal administration and supportive care led to a successful outcome in this patient.

An 18-month-old, spayed female Australian terrier cross was presented with a 10-month history of chronic large bowel diarrhea. Ulceration and two proliferative masses in the rectum were seen on colonoscopy. Surgical resection was performed to remove the masses, and the dog recovered without complications related to surgery. Histopathology was consistent with the diagnosis of ganglioneuroma. The dog had no clinical signs of disease within three months of surgery and was completely normal 2.5 years after diagnosis. This is the first report providing follow-up and successful outcome of a ganglioneuroma in the gastrointestinal tract of a dog.

A 12-year-old, neutered male Rough Collie was referred because of a 5-day history of lethargy and respiratory distress. A pneumothorax was detected on a right lateral radiography at the referring veterinary surgeon. Contrast-enhanced CT of the thorax was performed and a severe bilateral pneumothorax with a collapse of the left cranial lung lobe was observed. The underlying cause of the pneumothorax could not be found at that point and an exploratory thoracotomy was performed. The left cranial lung lobe had several perforations and a lobectomy was achieved. A thrombus obliterating a medium calibre artery and associated severe surrounding pulmonary necrosis were detected histologically.
