Urachal abscess without pathologic changes in the extra-abdominal navel in a cow. Case report

A rarely diagnosed case of urachal abscessation without any signs of inflammation of the extra-abdominal navel in a seven-month-old Braunvieh heifer is described. The symptoms of this disease, its diagnosis by the means of ultrasonographic examination and its therapy are explained. The technique of ultrasonographic examination is supposed to be a facilitation of presurgical diagnosis of umbilical disease. Nevertheless the value of this diagnostic procedure should be checked up on more patients.     

Dermoid sinus in a Rhodesian ridgeback. Case report]

The dermoid sinus, which occurs mainly in Rhodesian Ridgeback dogs, is discussed. One case of infected dermoid sinus in the sacrococcygeal region of a female Rhodesian Ridgeback is described. Although the dermoid sinus communicated with the subarachnoid space, the dog walked normally and had no neurologic deficits. The radical excision of the dermoid sinus was only possible by removing the laminae of the second and third sacral vertebrae. Surgical dissection was successful.     

Nephrolithiasis as a cause of colic in horses. Case report]

The results of clinical, ultrasonic, post mortem examinations and concrement analysis of a case with nephrolithiasis in a horse are described. Problems of diagnosis, etiology and occurrence of nephroliths in the horse are discussed.     

Abscess of the cervix uteri and uterine wall in a cow of German red-spotted breed

This report concerns a 5-year-old "Deutsche Rotbunte" cow, which was brought into the clinic because of fertility problems 5 months after its fourth calving. A medicine-ball-sized abscess extending from cervix and corpus uteri into the abdominal cavity was diagnosed. A presumable cause of the abscess could have been an uterine treatment carried out prior to insemination.     

Disseminated candidiasis in a calf. Case report

The pathological-anatomical and histological examinations of different organs from a calf that died at the age of 9 weeks indicated a disseminated candidiasis. Candida albicans was isolated from brain, lung, liver, spleen, kidney, intestinal lymph nodes and small intestinal contents. The antibiotics administered to the calf by the owner probably initiated the disseminated candidiasis.     

Recurrent, atypical uterine prolapse after the end of early puerperium in a cow of the German black pied breed (clinical case report)

A case of a recurrent incomplete uterine prolapse in a two year-old cow of the German Black Pied breed delivered into the clinic at the 16th day after parturition is described. An inversio uteri that possibly relapsed very soon following reposition of an uterine prolapse post partum is presumably the reason of the prolapsus uteri beyond the early puerperal period. The prolapsed left uterine horn was enclosed tightly by the cervix. Due to severe inflammatory changes a reduction was not practicable.     

Oral cavity diverticulum in a deer. Case report

The paper describes a deer with sacculation of the oral cavity floor. The diverticulum had no influence on ingestion and physical development.     

Chronic active or aggressive hepatitis and liver cirrhosis with copper accumulation in a Dobermann. Case report]

Clinical signs, haematological and biochemical abnormalities as well as the pathomorphological and electronmicroscopic findings observed in a 7 1/2 year old spayed female Dobermann suffering from chronic active hepatitis and cirrhosis are described. During almost the whole period of observation the clinical signs were nonspecific. The laboratory findings indicated a progressive liver disease. Gross findings revealed an atrophic cirrhosis. Histopathologically characteristic features of chronic active hepatitis were also seen together with a moderate copper accumulation localized in the periphery of the hepatic lobules. There was no evidence of cholestasis.     

Abscess in the heart septum of a cow. Necropsy findings

There is a case-report of an abscess in the septum of the heart of a thirteen-year-old cow in an advanced state of pregnancy.     

Enzootic abortion in a goat herd, caused by mixed infection with Coxiella burnetii and Chlamydia psittaci. Case report]

We report on an outbreak of enzootic abortion in a herd of goats with high losses caused by mixed infection with Coxiella burnetii and Chlamydia psittaci. Both agents could be detected by microscopic investigation of smears from afterbirths by Giménez staining and by a capture enzyme-linked immunofluorescence assay (Capture ELIFA). Additionally, Coxiella burnetii was isolated from the same tissues in BGM cell cultures. Serological investigations with CF, indirect ELIFA, and IF tests revealed high antibody titers against both agents in most animals. Coxiella antigen was still detected 91 days later in milk samples of two infected goats by Capture ELIFA.     

Neonatal thrombocytopenic purpura in a black and white male calf. Case report

A report is given on a newborn calf showing mucosal hemorrhage and melena. All blood clotting tests, except for prothrombin time (which proved to be initially prolonged), had normal results. The striking recurrent thrombocytopenia was successfully treated with prednisolone. Autoimmune idiopathic thrombocytopenia is suspected as a possible cause.     

Small intestine obturation and perforation in a calf caused by a foreign body. Case report

Obturation and perforation of the jejunum by an ingested fir branch was diagnosed in a 3 months old male German Fleckvieh calf. Following resection of the altered segment of intestine an end-to-end anastomosis was performed. The abdominal cavity was flushed with a 0.4% solution of polyvidon-iodine in normal saline, and an antibiotic preparation was instilled. Systemic antibiotic therapy was maintained for 6 days. Recovery was uneventful, and the animal was discharged 9 days after admission.     

Elasmobranch pericardial function. 3. The pericardioperitoneal canal in the horn sharkHeterodontus francisci

The pericardial and peritoneal spaces of elasmobranch fishes are connected by the pericardioperitoneal canal (PPC), which allows pericardial fluid to escape when pressures exceed 0.1–0.3 kPA. Using the horn shark (Heterodontus francisci), we tested the hypothesis that the PPC functions to increase cardiac stroke volume by lowering pericardial pressure during activity. We also assessed the role of the PPC during coughing, feeding, or burst swimming and examined the effects of PPC occlusion. Increases in heart size were not prevented following augmented venous return in sharks with undisturbed or occluded PCP, evidence that argues that pericardial fluid loss through the PPC is a cause of increased cardiac stroke volume and not the result. Coughs, feeding, and burst swimming led to discharge of pericardial fluid. Chronic PPC occlusion resulted in an increased pericardial pressure, fluid volume, and frequency of coughing, and a decreased survival time compared to shams. Thus, in the horn shark the PPC likely compensates for constraints that may be imposed by the pericardium, provides a route for pericardial drainage, and regulates cardiac stroke volume during periods of activity.     

Clitoral massage as a supporting measure in manipulation of the bovine uterus

A method of exciting the clitoris is described. After such a massage or stimulation of the clitoris, the cervix lumen enlarges and allows an easier passage. Thus one can assume that a reflex arc exists. Directions on how to arouse the "clitoris-cervix-reflex" can be requested by sending an international self addressed stamped envelope to the author.     

Ovarian hematoma and hemorrhage in a cow due to the manual rupture of cysts

The case of a German Black Pied cow at the age of about six years which died in consequence of an abdominal haemorrhage caused by the manual rupture of ovarious cysts is described. Based on this event, the legal aspects of manual surgical procedure on the bovine ovary are discussed.     

An unusual complication after the partial resection of the ascending duodenum of a cow

In a heifer portions of the ascending duodenum, which had been perforated by an obstructing phytobezoar, were resected. This resulted in an unexpected complication. The shortened ligamentum duodenocolicum exerted steady traction on the descending colon. This traction caused a kink and finally resulted in a total obstruction of the colon. The pathogenesis of this complication is illustrated. Surgical--possibly preventive--procedures are discussed.     

Intensive polyculture of fish in freshwater ponds. I. Substitution of expensive feeds by liquid cow manure

In 1974 and 1975 nine experimental treatments of fish polyculture in stagnant water ponds without aeration were conducted at Dor. The polyculture was composed of common carp, silver carp, white amur (grass carp) and Tilapia. The treatments differed in stocking densities, feeding and manuring levels. The most productive treatment of the experiment, in which the fish were fed with protein-rich pellets, produced 50 kg/ha per day, probably a record for unaerated ponds of stagnant water. Two treatments (low and high stocking densities) fed exclusively with liquid cow manure produced an average yield of around 32 kg/ha per day. The yields of the treatments receiving high-protein pellets exceeded those of the treatments receiving grain pellets by 20 and 9.6 kg/day per ha, at high and low stocking densities, respectively, and in both cases the yield increments justified the extra cost of high-protein feed. The responses of the four fish species to the different levels of feeding and stocking densities were widely different. The common carp and white amur showed the greatest responses to increased feeding inputs while the silver carp and Tilapia, even at high densities, have done equally well at low feeding levels. Total body fat contents of the common carp were 20%, 15% and 6.2% when fed with high-protein pellets, grains pellets and liquid cow manure, respectively. Intermittent harvesting did not result in increased yields.
