Management of traumatic ulcerative keratitis in a Red Serow

Red Serow Capricornis rubidus is an elusive herbivore native to the montane forests of the Himalaya. Currently it is categorized as ‘Vulnerable’ in the IUCN Red List and placed under Schedule I species of the Wildlife Protection Act, 1972. A serow was presented with complaints of mild inappetence, irritability, sporadic scratching of head over the enclosure barrier and serous ocular discharge from the left eye. Based on detail clinical examination, the animal was diagnosed with unilateral conjunctivitis, corneal oedema, and ulcerative keratitis. A combination of Xylazine @ 1.5mg/ kg body weight and Zolatile® (zolazepam and tiletamine) @ 2.5 mg/kg body weight was used to chemically restrain the animal, followed by auriculo-palpebral nerve block using 1 ml of 2 % lignocaine hydrochloride. The affected eye was adequately cleaned with isotonic sterile Normal Saline solution (NSS). Combination of 0.5 ml of ceftriaxone and 0.5 ml of flubiprofen was injected into upper and lower palpebral conjunctiva. The cornea and the third eyelid flap were carefully sutured using 5-0 and 3-0 Vicryl, respectively. Finally, tarsorrhaphy was done using 2-0 nylon. Post-operative care consisted of an antibiotic regimen of Cephalaxin @ 20 mg/ kg body weight b-i.d-twice in a day for seven days along with probiotic supplement (Vizylac®) and Vitamin A capsules (Aquasol A®) orally once daily for the next 30 days. The animal showed complete recovery within 30 days of proper treatment, monitoring, care and management.

Corneal stromal abscess and anterior uveitis in a pet goat

A 3-year-old non-lactating pet goat was referred to our clinic due to advanced ocular lesions and blindness of the left eye (Figure 1). According to the case history, two weeks ago, a grass awn penetrated and injured the eye. The awn was removed by the owner immediately. The following day, the goat had serous ocular discharge and photophobia and was referred to a private veterinarian. The veterinarian did not find any remaining piece of the awn and prescribed tetracaine eye drops to be administered twice a day for the next 4 days. The treatment was not successful and the eye’s condition deteriorated the following days.

CLINICAL AND PATHOLOGICAL STUDY OF THEILERIOSIS IN CATTLE AND BUFFALOES IN AL-GHANIEM REGION, ASSIUT GOVERNORATE, UPPER-EGYPT

A detailed Clinico-pathological profile of clinically diseased cattle and buffaloes with Theileriosis located in Al-Ghaniem region, Assiut Governorate, was aimed. Theileria annulata was confirmed by the presence of T. annulata piroplasms in blood smears and/or lymph smears followed by polymerase chain reaction (PCR). During the period of investigation (April 2015 to August 2018), out of the clinically inspected cattle (n= 300) and buffaloes (n= 100), 80 (26.67%) and 15 (15 %) cases were clinically suspected to have Theileriosis, respectively. The positive cases were molecularly identified (PCR). The general observed signs were anorexia, fever, swelling of superficial lymph nodes. ocular lesions were white cloudiness were more obvious in the center of cornea rather than the borders (yellowish colored corneoscleral opacity surrounded by hyperemic band). a watery discharge from the eyes. Serous ocular discharge (watery lacrimation) was remarkable, however in severe cases the ocular discharges was accumulated in the medial canthus. Some newly born calves of less than one month exposed to ocular symptoms mainly protruding of eye ball with ictric conjunctiva. The clinical examination of conjunctivae of the clinically suspected cases with Theileriosis indicated that icteric appearance of conjunctivae in some cases. Three cases showed petechiated conjunctivae. In our study some animals showed up--word visible bulging of temporal fossa. visible protrusion of hemorrhagic conjunctiva with apparently exophthalmia (ocular edema) were observed. Bloody diarrhea and tarry like diarrhea, change in feeding behavior or habit like depraved appetite by eating mud ,soil were noticed. On the other side, the most prominent necropsy features the recently succumbed animals: Gross changes in various organs including heart lungs, trachea, stomach, liver, spleen, kidneys superficial lymph nodes, mesenteric lymph nodes, small and large intestine. All mucous membranes and conjunctivae, peritoneum and abdominal fatty tissues were icteric. On external observation. Jaundice, petechial hemorrhages involving mucosal and serosal surfaces of many organs as well as body fat. In the thoracic cavity, the most prominent autopsy findings were obviously extra edematous swelling of all lobes of the lung, hydrothorax and the lung was distended, discolored, solid in texture, and filled with exudate by palpation, The liver was friable, yellowish, and larger than normal, with the gall bladder being markedly distended with dark olive-green or brownish green bile. The abomasum was the most severely affected organ in the alimentary canal, it contains numerous ulcers about 3 mm. in diameter .a few linear ulcers were present on the leaves. There were prominent hemorrhagic ulcers and petechial hemorrhages were seen in the abomasum of the most cases. There were remarkable enlargement of spleen (splenomegaly) were also recorded. The kidneys were congested or dark brown in color and their perirenal fat were yellowish in color. The heart had petechial and hemorrhages on the outer and inner surface of the auricles.

Recovered case of sheep‐associated malignant catarrhal fever in a gravid cow

A four‐year‐old Brown Swiss cow was referred to the University Clinic for Ruminants in Vienna. At the first clinical examination the cow showed the following clinical signs: body condition score 2 out of 5, respiratory rate of 38 per minute, body temperature of 38.1°C, moderate hyperaemia of the conjunctival mucous membranes with severe serous ocular discharge, injection of the scleral vessels and bilateral opacity of the cornea were present. The nasal mucous membranes were pink and a moderate amount of mucopurulent nasal discharge was present. Harsh lung sounds were audible at auscultation and all teats presented with multiple erosions. Definitive diagnosis was the eye form of malignant catarrhal fever with additional pathological changes at the teats. The cow was treated intensively with antibiotics, NSAID, intravenous infusion (sodium chloride and glucose) and rumen fluid, and was discharged from the clinic seven days after admission. The offspring was clinically healthy.

Dyspnea in a Degu (Octodon degu) Associated with Maxillary Cheek Teeth Elongation

An adult, 2-year-old, 173g, intact male degu (Octodon degus) was presented to the authors’ clinic with a 2-week history of reduced food intake, weight loss, epiphora, and dyspnea. Physical examination revealed lethargy, cachexia, bilateral serous ocular discharge, dehydration, inspiratory dyspnea, and severe dental disease. Diagnostic investigation showed extensive apical elongation of premolars causing partial nasal cavity obstruction by masses of increased opacity, and loss of conchal detail. The animal was euthanized due to general poor condition and the severity of disease. Postmortem micro–computed tomography showed marked reserve crown elongation of all premolars and molars. All cheek teeth were abnormally curved and had widened interdental spaces. The apex of the maxillary left premolar nearly penetrated the left nasal bone. Both maxillary premolars penetrated into the nasal cavity and caused complete left and partial right nasal cavity obstruction. Apices of all premolars were dysplastic.

Surto de ceratoconjuntivite infecciosa bovina e hemoncose causando mortalidade em bezerros

É descrito um surto de ceratoconjuntivite infecciosa bovina (CIB) e hemoncose intercorrente afetando um grupo de 116 bezerros de 1-2 anos de idade na região central do Rio Grande do Sul. Vinte bezerros foram afetados e nove morreram. Os sinais clínicos incluíam perda de peso, marcada palidez da mucosa oral, lacrimejamento, opacidade focal da córnea e avermelhamento da conjuntiva. Sinais mais avançados incluíam lacrimejamento copioso, opacidade da córnea, ceratocone, ceratomalacia e cegueira. O diagnóstico de CIB foi baseado nos achados epidemiológicos e clínico-patológicos e confirmado pela cultura de uma cepa hemolítica de Moraxella bovis dos olhos de dois terneiros afetados. O alto coeficiente de letalidade (45%) neste surto foi atribuído a grave hemoncose intercorrente.

Baccharis megapotamica var. weirii poisoning in water buffalo (Bubalus bubalis)

An outbreak of an acute disease in buffalo (Bubalus bubalis) caused by the ingestion of Baccharis megapotamica var. weirii occurred in the southern region of Brazil. Ten out of 50 buffalo died 24-48 hr after being introduced into a pasture containing abundant amounts of the plant. Factors influencing the ingestion of the plant and consequent toxicosis included hunger, stress caused by shipment, and unfamiliarity with the plant. Clinical signs included serous ocular discharge, incoordination, mild bloat, and muscle trembling. One buffalo was necropsied. Gross findings included dehydration, abundant liquid in the rumen, reddening of the mucosa of forestomachs, abomasum, and intestine, and edema of the wall of the rumen. The main histologic lesions were superficial to full thickness degeneration and necrosis of the stratified epithelium lining the forestomachs, necrosis of the intestinal mucosa, and widespread lymphoid necrosis. A calf (Bos taurus) was fed a single dose of 5 g/kg/body weight of B. megapotamica var. weirii harvested from the same site where the buffalo died. Twenty hours after the administration of the plant this calf died with clinical signs and lesions similar to those observed in the naturally poisoned buffalo.

LIGNEOUS CONJUNCTIVITIS IN A HORSE: A CASE OF ELEVEN MONTHS DURATION

A six months old throughbred female race horse was received presenting events of mucous purulent discharge from the right eye for two days. Close examination of both eyes revealed bilateral mucous purulent conjunctivitis, more severe on the left eye where discharge was more profuse, with tarsal and bulbar chemosis and blepharospasm. This animal also had a fluoresceine fixing superficial linear ulcer on the left eye. It was performed culture of material from the botton of conjunctive sack, which revealed an infection by Pseudomonas spp, sensitive to tobramycine. Based upon microbiological tests, tobramycine eye drops (15 mg/ml) and ophtalmic ointment (15 mg/g) was given for three weeks, and a two percent atropine and one percent dichorphenac eye drops were given for five days. At the end of the treatment, the right eye was calm and without alterations while the left eye displayed a tarsal membranous conjunctivitis with minimal serous ocular discharge. The presence of an allergic conjunctivitis was suspected and four percent dissodium chromoglicate eye drops were given. In spite of the decrease of inflamation observed, the conjunctive membranes remained. Surgical debridement of the membranes was performed and representative material was collected and sent for histological examination. Based upon human and canine reports and histological findings, the most probable diagnosis was ligneous conjunctivitis. After biopsy, the drug chromoglicate was replaced by one percent prednisolone eye drops for three weeks. After this, the eye showed a discreet dorsal tarsal chemosis and hyperemia but no membranous conjunctivitis. As supporting therapy a daily morning instillation of corticoid for 30 days was ordered. Five months later, a recurrence of the membranous conjunctivitis was verified and these membranes invaded the cornea, causing temporal pigmentary keratitis. A two percent cyclosporine ointment was then given and a new biopsy asked. The diagnosis of recurrent severe ligneous conjunctivitis was evident, and a wide surgical resection of the membranes and vascular cauterization was decided. Postoperative treatment was composed by one percent prednisolone, one and a half percent tobramicine eye drops together with 5,000 IU /ml heparin. Treatment proceeded for 30 days when the antibiotic was taken off, corticoid frequency was reduced and topic heparin kept. Ligneous conjunctivitis is a chronic membranous conjunctivitis with presence of membranes mainly in the tarsal superior conjunctives, of ignored etiology. Up to the present, two months after the surgical resection of the membranes, the topical use of corticoid and heparin satisfactorily controls the case, now eleven months old.

Infecção natural pelo Vírus Sincicial Respiratório Bovino (BRSV) no Estado de Alagoas

Descreve-se a ocorrência de infecção pelo vírus sincicial respiratório bovino (BRSV) em bezerros descendentes de animais das raças pardo-suíça e holandesa importados da Alemanha, Áustria, Suíça e Uruguai, na qual morreram em Alagoas, Brasil, pelo menos 220 cabeças, de 1995 até a presente data. O quadro clínico caracterizou-se por hipertermia, tosse seca, mais tarde dispnéia acentuada e por vezes lacrimejamento; à auscultação havia estertores secos, depois úmidos, com sibilos, muitas vezes audíveis à distância. O exame histológico revelou pneumonia intersticial com formação de células sinciciais, infiltração predominantemente linfocitária com presença de eosinófilos e de corpúsculos de Russel, proliferação de pneumócitos tipo II e leve metaplasia escamosa. Células epiteliais de bronquíolos e células sinciciais marcaram-se positivamente com o anticorpo anti-BRSV. A ocorrência da enfermidade no Sul e agora no Nordeste do Brasil indica a necessidade de se promover um amplo levantamento epidemiológico para se avaliar o grau de perdas e a proporção de animais infectados no país. Lembramos que parte dos animais importados, ao que tudo indica, já estavam infectados nos países de origem, quando desembarcaram em Belém, Pará.

Conjunctival lipid granulomas in a cat

A 12-year-old, neutered male cat was examined because of a persistent serous ocular discharge from the left eye. Three, pale cream, 1-4 mm lesions were detected in the palpebral conjunctivae of the left eye. The surgical excision of the lesions resulted in complete resolution of the epiphora. Histological examination confirmed that the lesions were lipid granulomas but the aetiology and pathogenesis of them were not determined. No disease conditions which result in primary or secondary hyperlipoproteinaemia were detected.

White liver disease in lambs.

An outbreak of white liver disease in lambs in Western Australia is described. The disease affected 2- to 3-month-old lambs and was characterised by liver damage, severe ill-thrift, depression, serous ocular discharge, photosensitization, and a high mortality rate. Transient central nervous system signs occurred. A positive response to vitamin B12 therapy was demonstrated.

Viruses associated with feline respiratory disease in Dunedin.

Abstract Extract In Dunedin, feline respiratory infections with a high morbidity, but a low mortality except in very young animals, commonly occur in epizootics and appear to be enzootic between these outbreaks. The affected animals develop a serous ocular discharge which later becomes mucoid, and a mucoid nasal discharge associated with sneezing especially after handling. While these signs of infection are present, the animals are anorexic and listless. The disease may last for two weeks or more and sometimes affected cats develop a chronic snuffle lasting for months despite treatment. The disease is usually referred to as “snuffles”, although it is probably identical with the syndrome called “rhinotracheitis”. In the summer time, it commonly occurs in boarding establishments where large numbers of pets collected from a wide area are left by summer vacationers. In breeding catteries, infections occur most often in the spring and especially at the time of the first warm weather. Young kittens about 5 to 1...
