SHORT COMMUNICATION: Normal aerobic bacterial conjunctival flora in the Crab‐eating raccoon (Procyon cancrivorus) and Coati (Nasua nasua) housed in captivity in pernambuco and paraiba (Northeast,Brazil)

Objective To determine the normal aerobic bacterial conjunctival population of the Coatis and the Crab‐eating raccoons housed in captivity in the Pernambuco and Paraiba states of Brazil. Animals studied Ten healthy Coatis and 10 healthy Crab‐eating raccoons were selected for this study. Animals are from three zoos situated at the Pernambuco and Paraiba States in the north‐east of Brazil. Procedures After ophthalmologic examination, swabs from healthy animals were carefully collected in order to avoid contamination. Samples were identified and submitted to the laboratory. Swabs were plated for culture on ovine blood agar (8%) and agar Levine and incubated at 37 °C and observed 24 and 48 h. Results Staphylococcus spp. was the most common microorganism isolated from conjunctival sac. Shigella spp. comprised the Gram‐negative genera isolated. Escherichia coli were isolated from the right eye of one Coati that had no growth at contralateral eye. Nine eyes from coatis and 10 from Crab‐eating raccoons had no microorganisms isolated. Conclusion Our results were in accordance with previous studies indicating Staphylococcus sp., followed by Corynebacterium spp. as the most common inhabitant of the eyes of most mammalian species.     

Eosinophilic pulmonary granulomatosis in a young dog with prolonged remission after treatment

A two‐year‐old Jack Russell terrier was presented for evaluation of chronic cough and exercise intolerance. Previous treatment with antibiotics and glucocorticoids had only partially ameliorated the clinical signs. During investigation, hypoxaemia, peripheral eosinophilia and an eosinophilic bronchoalveolar lavage fluid were noted. Thoracic radiographs revealed two ovoid clearly delineated soft‐tissue opacities, one in the caudal segment of the left cranial lung lobe (diameter 26 mm) and the other in the right cranial lung lobe (diameter 20 mm). These findings were verified by computed tomography, which identified an additional smaller lesion (diameter 16 mm) dorsally in the right caudal lobe. Ultrasound‐guided fine‐needle aspiration samples confirmed the diagnosis of eosinophilic pulmonary granulomatosis and treatment with prednisolone and azathioprine was initiated. Within 1 month, granulomas were no longer detectable radiographically. All medication was discontinued after 7 months and currently, after 2·5 years, the dog remains free of clinical signs. To the authors’ knowledge this is the first case report to describe prolonged remission from idiopathic canine eosinophilic pulmonary granulomatosis.     

The New Zealand meat industry

Extract

At the outset, some idea might be given of the size and scope of the industry, the various types of business involved and the roles played by the Meat Producers' Board, the government, and the trade.     

Simultaneous resistance to two or more broad-spectrum anthelmintics by gastrointestinal nematode parasites of sheep and goats

The detection, by means of faecal egg count reduction tests and larval cultures, of two cases of multiple anthelmintic resistance in goats and two in sheep, is reported. The former cases appeared to involve resistance to all three broad-spectrum drench groups (benzimidazole, levamisole, ivermectin) by mainly Ostertugia spp., the latter resistance to two of them (benzimidazole, levamisole) bv Trichostrondus spp. (New Zealand Veterinary Journal 38, 114–117, 1990)

Treatment of cervical oesophageal rupture in horses

Oesophageal rupture in horses has only been previously described in detail in isolated case reports. The objectives of this study were to describe the clinical findings, specific treatment and outcome of oesophageal rupture in horses. Medical records of horses diagnosed with oesophageal rupture between 1994–2008 were reviewed. Clinical findings, treatment and outcome were recorded. Seven horses with cervical oesophageal perforations were included in the study. Two horses were subjected to euthanasia without treatment and 5 were treated surgically. Treatment involved a fasciotomy of the cervical musculature and oesophageal tube placement. Three of 5 horses survived long‐term (>one year). Our study showed that surgical treatment of cervical oesophageal rupture involving fasciotomy and oesophagostomy tube placement can be successful with 3/5 of treated horses surviving more than one year.     

Hydrothermal Assessment of Temporal Variability in Seedbed Microclimate

The microclimatic requirements for successful seedling establishment are much more restrictive than those required for adult plant survival. The purpose of the current study was to use hydrothermal germination models and a soil energy and water flux model to evaluate intra- and interannual variability in seedbed microclimate relative to potential germination response of six perennial grasses and cheatgrass. We used a 44-yr weather record to parameterize a seedbed microclimate model for estimation of hourly temperature and moisture at seeding depth for a sandy loam soil type at the Orchard Field Test Site in southwestern Ada County, Idaho. Hydrothermal germination response was measured in the laboratory for two seed lots of cheatgrass (Bromus tectorum L.), four seed lots of bluebunch wheatgrass (Pseudoroegneria spicata [Pursh] Löve), three seed lots of bottlebrush squirreltail (Elymus elymoides [Raf] Swezey), and one seed lot each of Sandberg bluegrass (Poa secunda J. Presl.), big squirreltail (Elymus multisetus [J.G. Smith] M.E. Jones), thickspike wheatgrass (Elymus lanceolatus [Scribn. And J.G. Smith] Gould) and Idaho fescue (Festuca idahoensis Elmer). Germination response models were developed to estimate potential germination rate for 13 subpopulations of each seed lot for every hour of the 44-yr simulation. Seedbed microclimate was assessed seasonally and for each day, month, and year, and germination rate-sum estimates integrated for a numerical index of relative site favorability for germination for each time period. The rate-sum favorability index showed a consistent pattern among seed lots for different years, and provides a relatively sensitive indicator of annual and seasonal variability in seedbed microclimate. This index could be used with field data to define minimum weather thresholds for successful establishment of alternative plant materials, in conjunction with weather forecast models for making restoration and fire-rehabilitation management decisions in the fall season, for evaluation of potential climate-change impacts on plant community trajectories, and in optimization schemes for selecting among alternative restoration/rehabilitation management scenarios.
