Abstract
Fifteen cows with milk fever were treated with 500ml of 40 % calcium borogluconate (group A) administered intravenously. Fifteen other cows with milk fever received the same treatment, supplemented with 500ml of 10 % sodium phosphate administered intravenously, and 80g calcium as calcium lactate and 70g inorganic phosphorus as sodium phosphate administered orally in drinking water. The cows were monitored and blood samples collected for 3 days to measure the concentrations of total and ionized calcium, inorganic phosphorus and magnesium and the activity of creatine kinase. The two groups did not differ significantly with respect to the course of the disease. In each group 14 cows were cured. A rapid and significant increase in serum calcium concentration from the hypo- to the hypercalcaemic range occurred in both groups within 10min of the start of treatment, followed by a slow and steady decrease to the hypocalcaemic range. Calcium lactate did not prevent the calcium concentration from returning to the hypocalcaemic range, and the calcium profiles of the two groups did not differ significantly. As expected, treatment had little effect on the concentration of inorganic phosphorus in group A. In group B, treatment caused a rapid increase in the concentration of inorganic phosphorus to a maximum 20min after the start of treatment. This was followed by a slow decrease in the phosphorus concentration to the normophosphataemic range. Our findings confirmed that combined intravenous and oral administration of sodium phosphate in cows with periparturient paresis attributable to hypocalcaemia and hypophosphataemia results in a rapid and sustained increase in serum phosphorus, but not in serum calcium concentration. This modified therapy did not improve the success rate of milk fever treatment and further studies are needed to improve treatment of periparturient paresis.

Abstract
Eight cows underwent Doppler sonographic examinations of the milk vein and musculophrenic vein from 9 days prepartum to 300 days postpartum. A 7.5-MHz linear transducer was used to determine the inner diameter of the veins and blood flow velocities and volumes on the left side in standing, non-sedated animals. Cows were weighed and milk yield measured at all examination times. The milk vein appeared as a vessel with an inner diameter of 2.01-2.30 cm immediately beneath the skin. The maximum blood flow velocity ranged from 23.84 to 35.76 cm/s before parturition, increased markedly on the day of calving (day 0), peaked at 61.14 cm/s on day 1 and slowly decreased to 23.84 cm/s by day 300. The profiles of the minimum and mean maximum flow velocities and flow volume were similar. The musculophrenic vein had an inner diameter of 0.76-1.07 cm and its distance from the surface of the skin was 1.15-1.31 cm. The profiles of the blood flow variables were irregular and did not resemble those of the milk vein. The maximum blood flow velocity ranged from 87.35 to 114.41 cm/s, the minimum velocity from 5.47 to 7.60 cm/s, the mean maximum velocity from 48.55 to 78.74 cm/s and the blood flow volume from 1.02 to 2.44 l/min. The milk vein had a larger diameter (2.16 versus 0.90 cm; P<0.01), smaller maximum, minimum and mean maximum blood flow velocities (P<0.01) and a larger blood flow volume than the musculophrenic vein (P<0.01).

Abstract
This report describes an 8.8-year-old Simmental cow with squamous cell carcinoma of the reticulum and liver. The cow had calved recently and was referred to our clinic because of intractable fever, anorexia and progressive indigestion. The general condition and mental status were moderately affected and rectal temperature and respiratory rate were significantly elevated. There were no ruminal sounds and pinching of the withers consistently elicited a grunt. Serum activities of gamma glutamyl transferase, glutamate dehydrogenase and sorbitol dehydrogenase were elevated. Radiographic examination of the reticulum and ultrasonographic examination of the reticulum, liver and abdominal cavity revealed multifocal, poorly demarcated, heterogeneous and echogenic changes in the liver. Biopsy of these lesions yielded a diagnosis of squamous cell carcinoma. The cow was euthanized and a postmortem examination confirmed the diagnosis. A 15 by 15 cm neoplasm was found in the reticular wall, and histological examination showed squamous cell carcinoma. It was assumed that the reticular mass was the primary tumour, which metastasized to the liver via the portal vein.

Abstract
A monographic revision of the hyphomycete genus Cladosporium s. lat. (Cladosporiaceae, Capnodiales) is presented. It includes a detailed historic overview of Cladosporium and allied genera, with notes on their phylogeny, systematics and ecology. True species of Cladosporium s. str. (anamorphs of Davidiella), are characterised by having coronate conidiogenous loci and conidial hila, i.e., with a convex central dome surrounded by a raised periclinal rim. Recognised species are treated and illustrated with line drawings and photomicrographs (light as well as scanning electron microscopy). Species known from culture are described in vivo as well as in vitro on standardised media and under controlled conditions. Details on host range/substrates and the geographic distribution are given based on published accounts, and a re-examination of numerous herbarium specimens. Various keys are provided to support the identification of Cladosporium species in vivo and in vitro. Morphological datasets are supplemented by DNA barcodes (nuclear ribosomal RNA gene operon, including the internal transcribed spacer regions ITS1 and ITS2, the 5.8S nrDNA, as well as partial actin and translation elongation factor 1-α gene sequences) diagnostic for individual species. In total 993 names assigned to Cladosporium s. lat., including Heterosporium (854 in Cladosporium and 139 in Heterosporium), are treated, of which 169 are recognized in Cladosporium s. str. The other taxa are doubtful, insufficiently known or have been excluded from Cladosporium in its current circumscription and re-allocated to other genera by the authors of this monograph or previous authors.

Abstract
The oral administration of calcium lactate for prophylaxis of bovine parturient paresis has been promoted for a number of years. The goal of the present study was to investigate the effect of this treatment on the serum concentrations of calcium, inorganic phosphorus and magnesium in parturient cows. Five fresh calved cows were given a drench containing calcium lactate and 5 control cows received the same drench but without calcium lactate. There were no significant differences in the serum concentrations of total and ionised calcium and magnesium between treated and control cows within 24 hours of treatment. Because the calcium lactate drench did not significantly affect calcium concentrations in the blood of fresh cows, it appears highly questionable whether the administration of calcium lactate decreases the risk of bovine parturient paresis. Based on our results, the oral administration of calcium lactate can not be recommended for prophylaxis of bovine parturient paresis.

Abstract
A five-year-old Brown Swiss bull was referred to the Department of Farm Animals, University of Zurich, because of bilateral epiphora that was unresponsive to treatment. Clinical examination revealed a fistulous opening medial to the medial canthus of both eyes and mucopurulent discharge from both openings. Attempts to flush the nasolacrimal duct via the lacrimal points resulted in the fluid exiting via the fistulous opening. Retrograde flushing of the nasolacrimal duct from the nasolacrimal opening resulted in the flush fluid flowing back out the nasolacrimal opening. Bilateral lacrimal fistula medial to the medial canthus of the eye was diagnosed based on the findings. The same anomaly was diagnosed a year later in 4 related female animals referred to our Department for other reasons. Three of the cases were sired by the bull described above and one was sired by his half-brother. Therefore, an autosomal recessive mode of inheritance of this anomaly was assumed. Clinical, epidemiological and molecular studies of the offspring of both bulls are underway to further investigate this anomaly.

Abstract
BACKGROUND Blind insertion of endotracheal tubes through the intubating laryngeal mask airway (ILMA) is unsuccessful in almost 50% of cases on the first attempt, with an overall success rate of approximately 90%. We used a portable fiber optic device (Foley Airway Stylet Tool® FAST) to detect the reasons for failed intubations and tested its use in facilitating endotracheal tube placement. METHODS Thirty patients without anticipated intubation difficulties participated in the study. The fiber optic device was fastened with its tip at the end of the endotracheal tube, and both instruments were advanced through the previously inserted ILMA past the lifting bar. The view was scored in the following manner: I, full view of laryngeal inlet; II, partial vocal cords, arytenoids, epiglottis; III, epiglottis; IV, no laryngeal structures identifiable. The ILMA was adjusted for the best obtainable view, which was scored, and the endotracheal tube was inserted. RESULTS The initial laryngeal view was I in four patients, II in eighteen patients, III in one patient and IV in seven patients. The best view after corrective maneuvers was I in twenty-seven patients, II in two patients and IV in one patient. First attempt tracheal intubations were successful in twenty-seven (90%) patients; two patients required a second attempt. CONCLUSION A grade II view or worse indicated misalignment of the ILMA with the glottis. An endotracheal tube inserted blindly through the misaligned ILMA will impinge on and potentially damage laryngeal structures. The use of a portable fiber optic device can help reduce the failure rate of endotracheal intubations by utilizing ILMA in emergent situations.

Abstract
The genus Cladosporium is restricted to dematiaceous hyphomycetes
with a coronate scar type, and Davidiella teleomorphs. In the present
study numerous cladosporium-like taxa are treated, and allocated to different
genera based on their morphology and DNA phylogeny derived from the LSU nrRNA
gene. Several species are introduced in new genera such as
Hyalodendriella, Ochrocladosporium, Rachicladosporium,
Rhizocladosporium, Toxicocladosporium and
Verrucocladosporium. A further new taxon is described in
Devriesia (Teratosphaeriaceae). Furthermore, Cladosporium
castellanii, the etiological agent of tinea nigra in humans, is
confirmed as synonym of Stenella araguata, while the type species of
Stenella is shown to be linked to the Teratosphaeriaceae
(Capnodiales), and not the Mycosphaerellaceae as formerly
presumed.

Abstract
The phylogeny of the genera Periconiella, Ramichloridium,
Rhinocladiella and Veronaea was explored by means of partial
sequences of the 28S (LSU) rRNA gene and the ITS region (ITS1, 5.8S rDNA and
ITS2). Based on the LSU sequence data, ramichloridium-like species segregate
into eight distinct clusters. These include the Capnodiales
(Mycosphaerellaceae and Teratosphaeriaceae), the
Chaetothyriales (Herpotrichiellaceae), the Pleosporales, and
five ascomycete clades with uncertain affinities. The type species of
Ramichloridium, R. apiculatum, together with R. musae,
R. biverticillatum, R. cerophilum, R. verrucosum, R. pini, and three new
species isolated from Strelitzia, Musa and forest soil,
respectively, reside in the Capnodiales clade. The human-pathogenic
species R. mackenziei and R. basitonum, together with R.
fasciculatum and R. anceps, cluster with Rhinocladiella
(type species: Rh. atrovirens, Herpotrichiellaceae,
Chaetothyriales), and are allocated to this genus. Veronaea
botryosa, the type species of the genus Veronaea, also resides
in the Chaetothyriales clade, whereas Veronaea simplex
clusters as a sister taxon to the Venturiaceae (Pleosporales), and is
placed in a new genus, Veronaeopsis. Ramichloridium
obovoideum clusters with Carpoligna pleurothecii (anamorph:
Pleurothecium sp., Chaetosphaeriales), and a new combination
is proposed in Pleurothecium. Other ramichloridium-like clades
include R. subulatum and R. epichloës (incertae sedis,
Sordariomycetes), for which a new genus, Radulidium is
erected. Ramichloridium schulzeri and its varieties are placed in a
new genus, Myrmecridium (incertae sedis, Sordariomycetes).
The genus Pseudovirgaria (incertae sedis) is introduced to
accommodate ramichloridium-like isolates occurring on various species of rust
fungi. A veronaea-like isolate from Bertia moriformis with
phylogenetic affinity to the Annulatascaceae (Sordariomycetidae) is
placed in a new genus, Rhodoveronaea. Besides
Ramichloridium, Periconiella is also polyphyletic.
Thysanorea is introduced to accommodate Periconiella papuana
(Herpotrichiellaceae), which is unrelated to the type species, P.
velutina (Mycosphaerellaceae).

Abstract
Cladosporium chlorocephalum (= C. paeoniae) is a common, widespread leaf-spotting hyphomycete of peony (Paeonia spp.), characterised by having dimorphic conidiophores. During the season, one stage of this fungus causes distinct, necrotic leaf-blotch symptoms on living leaves of Paeonia spp. In late autumn, winter or after overwintering, a second morphologically distinct conidiophore type occurs on dead, blackish, rotting stems. Conspecificity of the two morphs, previously proposed on the basis of observations in culture, was supported by DNA sequence data from the ITS and LSU gene regions, using cultures obtained from leaf-blotch symptoms on living leaves, as well as from dead stems of Paeonia spp. Sequence data were identical, indicating a single species with two morphs. On account of its distinct conidiogenous loci and conidial hila, as well as its sequence-based phylogenetic position separate from the Davidiella/Cladosporium clade, the peony fungus has to be excluded from Cladosporium s. str., but still belongs to the Davidiellaceae (Capnodiales). The leaf-blotching (cladosporioid) morph of this fungus morphologically resembles species of Fusicladium, but differs in having dimorphic fruiting, and is phylogenetically distant from the Venturiaceae. The macronematous (periconioid) morph resembles Metulocladosporiella (Chaetothyriales), but lacks rhizoid conidiophore hyphae, and has 0-5-septate conidia. Hence, C. chlorocephalum is assigned to the new genus Dichocladosporium.

Abstract
The Cladosporium herbarum complex comprises five species for which Davidiella teleomorphs are known. Cladosporium herbarum s. str. (D. tassiana), C. macrocarpum (D. macrocarpa) and C. bruhnei (D. allicina) are distinguishable by having conidia of different width, and by teleomorph characters. Davidiella variabile is introduced as teleomorph of C. variabile, a homothallic species occurring on Spinacia, and D. macrospora is known to be the teleomorph of C. iridis on Iris spp. The C. herbarum complex combines low molecular distance with a high degree of clonal or inbreeding diversity. Entities differ from each other by multilocus sequence data and by phenetic differences, and thus can be interpreted to represent individual taxa. Isolates of the C. herbarum complex that were formerly associated with opportunistic human infections, cluster with C. bruhnei. Several species are newly described from hypersaline water, namely C. ramotenellum, C. tenellum, C. subinflatum, and C. herbaroides. Cladosporium pseudiridis collected from Iris sp. in New Zealand, is also a member of this species complex and shown to be distinct from C. iridis that occurs on this host elsewhere in the world. A further new species from New Zealand is C. sinuosum on Fuchsia excorticata. Cladosporium antarcticum is newly described from a lichen, Caloplaca regalis, collected in Antarctica, and C. subtilissimum from grape berries in the U.S.A., while the new combination C. ossifragi, the oldest valid name of the Cladosporium known from Narthecium in Europe, is proposed. Standard protocols and media are herewith proposed to facilitate future morphological examination of Cladosporium spp. in culture, and neotypes or epitypes are proposed for all species treated.

Abstract
This report describes a 2.8-year-old Swiss Braunvieh heifer with conjunctival changes as the lead clinical signs of malignant lymphoma. The heifer was referred to our clinic because of conjunctivitis that did not respond to treatment with antibiotics. The patient had bilateral lacrimation, severe swelling of the third eyelids and prolapse of the conjunctivae, which were erythematous and covered with haemorrhagic crusts. A clinical examination revealed enlarged prescapular and prefemoral lymph nodes. Based on cytological examination of a fine needle aspirate from a prescapular lymph node, a tentative diagnosis of malignant lymphoma was made. The heifer was euthanased and a postmortem examination carried out. The conjunctival lesions consisted of diffuse multifocal nodules of varying size. There was generalised lymphadenopathy and beige nodules were seen in several internal organs. Histological and immunohistological examinations confirmed the diagnosis of multicentric leukosis characterised by T-cell lymphoblasts, which had also infiltrated the conjunctivae. Examination of a blood sample for enzootic bovine leukosis virus yielded a negative result.

Abstract
Ultrasonography is a very useful technique for diagnosing the cause of colic in cows. It allows visualisation of abnormal reticular contour and occasionally of abnormal contractility in cows with reticuloperitonitis. In right-displaced abomasum, the dilated abomasum can be detected between the right abdominal wall and the liver. Fluid ingesta are seen ventrally and a gas cap of varying size dorsally. Dilated loops of small intestines that are almost always static are the main diagnostic criterion for ileus of the small intestine, but the cause of the ileus can only rarely be determined. Cholestasis can almost always be diagnosed by imaging a dilated biliary system. With obstruction at the level of the hepatic portal, only the intrahepatic biliary ducts are dilated, while a dilatation of the entire biliary tract, including the gallbladder, occurs in the case of an obstruction near the duodenal papilla. Urinary tract diseases cause colic in cows when concrement or inflammatory products become lodged in a ureter. The importance of ultrasonography in the diagnosis of diseases causing colic in cows varies. For example, with colic attributable to ileus of the small intestines, cholestasis or urinary tract disease, ultrasonography is a very useful diagnostic tool. On the other hand, for diagnosis of left or right displacement of the abomasum or caecal dilatation, ultrasonography is generally not required, but it is helpful in difficult cases to confirm or rule out a tentative diagnosis and to avoid an unnecessary exploratory laparotomy.

ZusammenfassungDie Ultraschalluntersuchung eignet sich sehr gut zur diagnostischen Abklärung von Koliken beim Rind. Bei einer Reticuloperitonitis traumatica finden sich Veränderungen der Haubenkontur und eventuell der Haubenmotorik. Bei der rechtsseitigen Labmagenverlagerung ist der Labmagen zwischen die rechte Bauchwand und die Leber eingeschoben. Im ventralen Bereich des sonographischen Bildes stellt sich flüssiger Futterbrei und im dorsalen Bereich eine unterschiedlich große Gasansammlung dar. Für die Diagnose eines Dünndarmileus sind die dilatierten Därme und die meist aufgehobene Darmmotorik die wichtigsten sonographischen Kriterien, während die eigentliche Ileusursache nur selten dargestellt werden kann. Eine Cholestase lässt sich fast immer anhand des dilatierten Gallengangsystems nachweisen. Bei einer Obstruktion im Bereich der Leberpforte sind nur die intrahepatischen, bei einer solchen im Bereich der Papilla duodeni auch die extrahepatischen Gallengänge und die Gallenblase dilatiert. Erkrankungen des Harnapparats führen beim weiblichen Rind dann zur Kolik, wenn Konkremente oder entzündliche Produkte aus den Nieren in den Ureteren stecken bleiben. Die Ultraschalluntersuchung weist nicht bei jeder Krankheit die gleiche diagnostische Wertigkeit auf. Während ihr beim Dünndarmileus, bei der Cholestase und den vom Harnapparat ausgehenden Koliken große diagnostische Bedeutung zukommt, ist ihr Einsatz bei der Diagnostik der links- und rechtsseitigen Labmagenverlagerung sowie der Blinddarmdilatation viel seltener, nämlich bei unklaren klinischen Befunden, erforderlich. In solchen Fällen stellt sie sich aber als besonders wertvoll heraus, da mit ihrer Hilfe eine Verdachtsdiagnose bestätigt oder verworfen und die Zahl der lediglich aus diagnostischen Gründen durchgeführten Laparotomien stark vermindert werden kann.

Abstract
This report describes the findings in a bull with severe inflammation of the muzzle and nose attributable to a nose ring. The most striking finding was that the bull continually licked the right side of the upper lip. The muzzle and right upper lip were swollen, hard, reddened and partially depigmented. Mucopurulent nasal discharge and salivation were also noted, and palpation of the right upper lip was extremely painful. Based on the findings, purulent infection of the right side of the muzzle, right naris and external nasal passage was diagnosed. After removing the nose ring the affected areas were washed daily for four days with a camomile-containing solution after which a chlorhexidine and dexpanthenol salve was applied. The bull also received ceftiofur and ketoprofen. The general condition and appetite of the bull normalised within a few days, and the inflammatory lesions resolved with the exception of the areas of depigmentation. After ten days of treatment, the bull was considered healthy and discharged from the clinic.

Abstract
This case report describes the clinical, ultrasonographic and pathological findings in a five-year-old Swiss Braunvieh cow with extraskeletal chondroblastic osteosarcoma of the neck region. The cow was referred because of a firm, non-painful swelling, approximately 25 cm in diameter, which was situated mainly on the lower left side of the neck but extended to the right. Ultrasonographic examination of the mass revealed a chambered structure containing echoic material that was separated by hyperechoic septa. Chondroblastic osteosarcoma was diagnosed based on histological evaluation of a biopsy sample, and the diagnosis was confirmed by postmortem examination.

Abstract
This case report describes the clinical, ultrasonographic and cystoscopic findings and treatment in a two-year-old Swiss Braunvieh heifer with rupture of a patent urachus. The lead signs in the seven-month-pregnant heifer were markedly abnormal general condition and demeanour and a pear-shaped abdomen. The heifer had severe azotaemia, and abdominal ultrasonography revealed ascites, which was diagnosed as uroperitoneum based on an elevated creatinine level in the fluid. A patent urachus was identified during cystoscopy; the endoscope could be advanced beyond the apex of the urinary bladder into the urachus. Based on all the findings, a diagnosis of uroperitoneum attributable to rupture of a patent urachus was made. The urachus was ligated twice via a left-flank laparotomy. The general condition normalised within a few days of surgery, and the patient calved normally and was in good health at follow-up evaluation.
