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.

Bovine respiratory disease (BRD) is an important viral and/or bacterial disease that mainly affects feedlot calves. The involvement of Mycoplasma bovis in BRD can lead to chronic pneumonia poorly responsive to antimicrobial treatment. Caseonecrotic bronchopneumonia is a pulmonary lesion typically associated with M. bovis. In Spain, M. bovis is widely distributed in the feedlots and circulating isolates are resistant to most antimicrobials in vitro. However, the role of this species in clinical respiratory disease of feedlot calves remains unknown. Furthermore, available data are relative to a fixed panel of antimicrobials commonly used to treat BRD, but not to the specific set of antimicrobials that have been used for treating each animal. This study examined 23 feedlot calves raised in southeast Spain (2016–2019) with clinical signs of respiratory disease unresponsive to treatment. The presence of M. bovis was investigated through bacteriology (culture and subsequent PCR), histopathology and immunohistochemistry. The pathogen was found in 86.9% (20/23) of the calves, mainly in the lungs (78.26%; 18/23). Immunohistochemistry revealed M. bovis antigens in 73.9% (17/23) of the calves in which caseonecrotic bronchopneumonia was the most frequent lesion (16/17). Minimum inhibitory concentration assays confirmed the resistance of a selection of 12 isolates to most of the antimicrobials specifically used for treating the animals in vivo. These results stress the importance of M. bovis in the BRD affecting feedlot calves in Spain.

Abstract BackgroundAn outdoor pig herd was affected by severe respiratory disease in one out of three pastures. At necropsy, Mycoplasma hyopneumoniae and Pasteurella multocida were detected in the lungs, as well as the lung worm Metastrongylus apri. The life cycle of Metastrongylus spp. includes earth worms as an intermediate host, and since domesticated pigs mainly are reared indoors lungworms has not been diagnosed in domestic pigs in Sweden for decades, not even in pigs reared outdoors. Therefore, this disease outbreak was scrutinised from the view of validating the impact of Metastrongylus spp..ResultsAt the time of the disease outbreak, neither eggs of Metastrongylus spp. nor Ascaris suum were detected in faeces of pigs aged ten weeks. In contrast, five-months-old pigs at the pasture with respiratory disease shed large amounts of eggs from Ascaris suum, whereas Ascaris suum not was demonstrated in healthy pigs aged six months at another pasture. Low numbers of eggs from Metastrongylus spp. were seen in faecal samples from both these age categories.At slaughter, seven weeks later, ten normal weighted pigs in the preceding healthy batch were compared with ten normal weighted and five small pigs from the affected batch. Healing Mycoplasma-like pneumonic lesions were seen in all groups. Small pigs had more white spot liver lesions, and all small pigs shed eggs of Ascaris suum in faeces, compared to around 50% of the pigs in the normally sized groups. Metastrongylus spp. were demonstrated in 13 of the 25 pigs (52%), %), representing all groups included.ConclusionAs Metastrongylus spp. were demonstrated regardless of health status, and in another healthy outdoor herd, the impact of Metastrongylus spp. on the outbreak of respiratory disease was depreciated. Instead, Metastrongylus spp. was suggested to be common in outdoor production, although rarely diagnosed. The reason for this is because they will escape detection at routine inspection at slaughterhouses, and that they appeared to generally not induce clinical signs of respiratory disease. Instead, a possible association with a high burden of Ascaris suum was suggested to have preceded the severe outbreak with respiratory disease.

Background: Cerebral cavernous hemangioma is a rare neoplasm of vascular origin in the brain, characterized by abnormally dilated vascular channels surrounded by endothelium without muscle or elastic fibers. Presumptive diagnosis is performed by magnetic resonance or computed tomography (CT) scanning and can be confirmed by histopathology. The prognosis of intracranial cavernous hemangioma is poor, with progression of clinical signs culminating in spontaneous death or euthanasia. The purpose of this paper is to report a case of cerebral cavernous hemangioma in a dog, presenting the clinical findings, tomographic changes, and pathological findings.Case: This case involved a 2-year-old medium sized mixed breed female dog presenting with apathy, hyporexia, ataxia, bradycardia, dyspnea, and seizure episodes for three days. Hemogram and serum biochemistry of renal and hepatic function and urinalysis did not reveal any visible changes. CT scanning was also performed. The scans revealed a hyperdense nodule of 15.9 x 14 mm, with well defined borders, and a hypodense halo without post-contrast enhancement and mass effect in the right parietal lobe was observed in both transverse and coronal sections. Based on the image presented in the CT scans, the nodule was defined as a hemorrhagic brain lesion. The animal died after a seizure. The right telencephalon was subjected to necropsy, which revealed a reddish-black wel-defined nodule 1.7 cm in diameter extending from the height of the piriform lobe to the olfactory trine at the groove level and extending towards the lateral ventricle, with slight compression and deformation of the thalamus but no other macroscopic alterations in the other organs. The histopathology indicated that this nodular area in the encephalus contained moderate, well-delimited but unencapsulated cellularity, composed of large vascular spaces paved with endothelial cells filled with erythrocytes, some containing eosinophilic fibrillar material (fibrin) and others with organized thrombus containing occasional neutrophil aggregates. The endothelial cells had cytoplasm with indistinct borders, elongated nuclei, scanty crust-like chromatin, and cellular pleomorphism ranging from discrete to moderate, without mitotic figures.Discussion: The histological findings characterized the morphological changes in the brain as cavernous hemangioma, and the growth and compression of this neoplasm were considered the cause of the clinical signs of this dog. The main complaint was seizures, although ataxia and lethargy were also noted. These clinical signs are often related to changes in the anterior brain and brainstem. The literature does not list computed tomography as a complementary diagnostic method in cases of cerebral cavernous hemangioma in dogs, but CT scanning was useful in confirming cerebral hemorrhage. The main differential diagnosis for cerebral cavernous hemangioma would be a hamartoma, but what differentiates them histologically is the presence of normal interstices between the blood vessels, since no intervening neural tissue occurs in the case of cerebral hemangioma. Therefore, even in the absence of immunohistochemistry to more confidently confirm a cavernous hemangioma, the clinical signs, CT scans and especially the pathological findings were consistent with a case of cerebral cavernous hemangioma, a benign neoplasm with a poor prognosis due to the severe neurological changes it causes and its difficult treatment.

Abstract: Patients of post therapy lung tuberculosis (TB) that still have permanent or worsened clinical signs might be caused by chronic pulmonary aspergillosis (CPA). Diagnosis of CPA is difficult to confirmed without complete supporting tests. This study was aimed to establish whether Saint George’s Respiratory Questionnaire (SGRQ) could be used as diagnostic tool and predictor of the occurence of CPA in post therapy lung TB patients. This was an analytical observational study with a cross sectional design. There were 72 patients who had negative Gene Xpert sputum; 34.7% with positive Aspergillus-specific IgG. Their clinical signs were evaluated with SGRQ. The results showed that there was a very significant relationship between clinical score and CPA (p<0.0001). The lower the clinical score the less the probability of CPA. In this analysis we determined the diagnosis value of clinical score with a probability cut-off point = 0.5 which led to clinical score cut-off point of 45.6 with further results, as follows: sensitivity 68.0%; specificity 95.7%; positive predictive value 89.5%; negative predictive value 84.9%; OR 47.8, and CI 95% (9,2-248,2). In conclusion, SGRQ could be used as diagnostic tool and predictor of the occurence of CPA in post therapy lung TB patients.Keywords: post therapy lung TB; chronic pulmonary aspergillosis; Saint George’s Respiratory Questionnaire (SGRQ)  Abstrak: Pasien TB paru pasca terapi yang masih memperlihatkan gejala klinis menetap atau bahkan memberat dapat disebabkkan oleh adanya chronic pulmonary aspergillosis (CPA). Diagnosis CPA sulit ditegakkan tanpa adanya pemeriksaan penunjang yang lengkap. Penelitian ini bertujuan untuk menentukan apakah Saint George’s Respiratory Questionnaire (SGRQ) dapat menjadi alat bantu diagnostik serta prediktor terjadinya CPA pada pasien TB paru pasca terapi. Jenis penelitian ialah analitik observasional dengan desain potong lintang. Hasil penelitian mendapatkan 72 pasien dengan sputum Gene Xpert negatif (34,7% dengan positif IgG Aspergillus) dilakukan penilaian skor klinis menggunakan SGRQ. Hasil uji menunjukkan terdapat hubungan sangat bermakna antara skor klinis dengan terjadinya CPA (p<0,0001). Makin rendah skor klinis makin kecil peluang terjadinya CPA. Melalui analisis ini dapat ditentukan nilai diagnosis skor klinis SGRQ dengan mengambil titik potong peluang = 0,5. Nilai peluang = 0,5 memberikan titik potong skor klinis = 45,6.  Dengan titik potong skor klinis SGRQ = 45,6 diperoleh nilai-nilai diagnosis sebagai berikut: Sensitivitas = 68,0%; Spesifisitas = 95,7%; Nilai Prediksi Positif = 89,5%; Nilai Prediksi Negatif = 84,9%; OR = 47,8 dengan CI 95% (9,2-248,2). Simpulan penelitian ini ialah SGRQ dapat menjadi alat bantu diagnostik serta prediktor terjadinya CPA pada pasien TB paru pasca terapi.Kata kunci: tuberkulosis paru pasca terapi; chronic pulmonary aspergillosis; Saint George’s Respiratory Questionnaire (SGRQ)

A late summer outbreak of illness involving newborn infants and mothers is described. Seven infants and five mothers were studied. Although three enterovirus types were recovered from the infants, the outbreak was associated with infection by a variant of ECHO 11. Clinical signs included fever, diarrhea, upper respiratory disease, and aseptic meningitis. In three infants the antibody response significantly exceeded that of the mother. The evidence for an etiologic association of ECHO 11 infection with disease is reviewed.
