- Abstract
Modern portable ultrasound scan machines provide the veterinary clinician with an inexpensive and noninvasive method to further examine sheep on farms, which should take no more than 5 minutes with the results available immediately. Repeat examinations allow monitoring of the disease process and assessment of therapy. 5 MHz linear array scanners can be used for most organs except the heart and right kidney. Transthoracic ultrasonography is particularly useful for critical evaluation of lung and pleural pathologies. Transabdominal ultrasonographic examination can readily identify distended urinary bladder and advanced hydronephrosis., (Copyright © 2016 Elsevier Inc. All rights reserved.)

- Abstract
The utility of routine auscultation to detect and characterise the nature of a range of superficial lung and pleural pathologies in domestic sheep was assessed using ultrasonographic examination to indicate and localise pathologies pre-mortem. Necropsy examination was then used to fully characterise the nature and extent of the lesions. Auscultation recordings were made from 10 normal sheep with no clinical evidence of respiratory disease and with absence of significant superficial lung pathology, which was confirmed initially by ultrasound examination and subsequently at necropsy examination. A further two sheep with endotoxaemia and 30 sheep with well-defined lung lesions were also examined. Increased audibility of normal lung sounds in 4/10 normal sheep was associated with tachypnoea as a consequence of handling and transport during hot weather and was also observed in the two sheep with endotoxaemia. Moderate to severe coarse crackles detected in all advanced cases of ovine pulmonary adenocarcinoma (n=16) were audible over an area larger than the lesion distribution identified during ultrasound examination, and confirmed later at necropsy. Auscultation did not detect abnormal sounds in any of the five sheep with focal pleural abscesses (up to 10 cm diameter). Unilateral pyothorax caused attenuation of sounds relative to the contra-lateral normal lung in all three sheep with this condition. Marked fibrinous pleurisy caused attenuation of sounds relative to normal areas of lung in six sheep. No sounds resembling the description of pleural frictions rubs were heard in the sheep with marked fibrinous pleurisy (n=6) or associated with focal pleural abscesses (n=5). Routine interpretation of auscultated sound did not allow the presence of superficial lung pathology or its distribution to be accurately defined in the respiratory diseases represented in this study., (Copyright © 2009 Elsevier Ltd.

Vertebral body infections (variously described as vertebral body empyema or vertebral osteomyelitis) are an important differential diagnosis for paresis and paralysis in lambs. This article aims to outline the clinical signs, differential diagnoses, diagnostic techniques and pathological changes associated with this condition and to illustrate these with a case series.

Most Sarcocystis spp. infestations are asymptomatic and the cysts in various muscles are only discovered at slaughter. Sheep of all ages may be affected by sarcocysts but neurological signs originating from spinal cord disease are believed to be the most common disease presentation and are reported in 6 to 12-month-old lambs. These clinical signs are easily mistaken for vertebral empyema, therefore the prevalence of neurological disease caused by Sarcocystis spp. in the UK is probably under estimated. Lesions involving the brain result in a range of clinical signs from reduced mentation to hyperexcitability and seizure activity. Cerebrospinal fluid (CSF) collection and analysis may prove the most useful ancillary test in establishing a likely diagnosis in practice, with an increased lumbar CSF white cell count and elevated eosinophil percentage being consistent with parasitic infestation.

Examination of the lungs of adult sheep with chronic respiratory diseases was readily achieved using both 5MHz linear and sector scanners. Superficial lung abscesses in eight sheep appeared as anechoic areas containing multiple hyperechoic dots bordered distally by a broad hyperechoic capsule. Unilateral fibrinous pleurisy (2 sheep) appeared as an anechoic area containing a hyperechoic latticework. Ovine pulmonary adenocarcinoma (OPA) lesions appeared as sharply demarcated hypoechoic areas in the lung parenchyma initially in the cranioventral lung lobes (21 sheep) with lesions also present in the caudodorsal diaphragmatic lobe (11 sheep); abscesses and areas of calcification within the OPA tumour mass were also identified. Daily treatment with procaine penicillin for 30 consecutive days was successful in both sheep with unilateral fibrinous pleurisy and six sheep identified with superficial lung abscesses measuring 2-8 cmin diameter; only one of two sheep with more extensive lesions recovered. Auscultation of the chest failed to detect adventitious sounds in any of the ten sheep with lung abscesses; normal breath sounds were reduced over the area of fibrinous pleurisy; no pleuritic rubs were heard. Wheezes and crackles auscultated in some OPA cases and did not correlate well with lesions detected ultrasonographically. [ABSTRACT FROM AUTHOR]

Ovine pulmonary adenocarcinoma (OPA) is a contagious tumour of the lungs of sheep. It is also commonly known as Jaagsiekte, ovine pulmonary carcinoma or sheep pulmonary adenomatosis. OPA is generally considered a chronic wasting disease with progressive respiratory distress leading to emaciation, but it may be that early lung lesions predispose to secondary bacterial pneumonia causing sudden death despite antibiotic treatment. OPA is common in the UK and most other countries where sheep are farmed, but the disease may be grossly under-reported because few deaths are investigated on sheep farms. Disease transmission is facilitated by close confinement such as indoor housing. Effective control, and possible disease eradication, has been hampered by the lack of a suitable diagnostic test or vaccine. This article describes the clinical features of OPA and outlines current methods of diagnosis. Issues surrounding the development of improved diagnostic tests are discussed. INSET: Clinical signs.

ABSTRACT: Marked urinary bladder distension, hydroureters, bilateral hydronephrosis and peri-renal fluid accumulation were identified ultrasonographically in two rams from the same farm over two years. One ewe also showed urine staining, bladder distension and incontinence for six months. There were normal tail and rectal muscle tone, and normal perineal and pelvic limb reflexes in all sheep. A presumptive diagnosis of pelvic nerve dysfunction causing detrusor atony and bladder distension, with secondary, pressure-induced hydronephrosis, is suggested. Detailed dissection at necropsy found no evidence of urethral obstruction in either ram; the ewe was sold fat after six months' observation. Pelvic nerve dysfunction may readily be confused with partial urethral obstruction and this condition may be more widespread than previously considered. [ABSTRACT FROM AUTHOR]

ABSTRACT: Important recent developments in ovine footrot detail the importance of prompt parenteral antibiotic treatment and no foot trimming either as a curative or preventive procedure. The best treatment for individual sheep with footrot is reported to be an injection of long acting antibiotic (10 mg/kg of oxytetracycline) together with removal of all debris from the interdigital space and application of an antibacterial spray although tilmicosin was not included in these studies. Whole flock antibiotic injection with tilmicosin has been reported to greatly reduce the incidence of footrot for 1-3 years and eradicate contagious ovine digital dermatitis from flocks.

ABSTRACT: The presumptive clinical diagnosis of acute respiratory disease caused by Mannheimia haemolytica and Bibersteinia trehalosi ('pasteurellosis') in adult sheep is based upon findings of sudden severe illness, inappetence, pyrexia, marked toxaemia, and tachypnoea consistent with endotoxaemia. Gram-negative infections of other body systems present with broadly similar clinical signs but accurate diagnosis is not important because there is a good response to intravenous oxytetracycline and non-steroidal anti-inflammatory drug (NSAID) therapy despite the organ system involved. However, it is essential to identify and eliminate the initiating cause, most commonly infection with ovine pulmonary adenocarcinoma. Chronic bacterial infection of the lungs causes weight loss and poor appetite over several weeks/months. Auscultation alone fails to identify/define specific lesions and an accurate diagnosis is only achieved using ultrasonography. Arcanobacterium pyogenes is the most common isolate from lung abscesses and a good response is achieved with procaine penicillin administered daily for 4-6 weeks. Debility following the breeding season exacerbated by inadequate nutrition and housing during the winter months are likely to be important factors in the sex bias of such chronic respiratory tract infections.
