Dirofilaria repens is a parasitic nematode in the subcutaneous tissue of carnivores, including dogs and cats, transmitted by mosquitoes. Human beings may be accidental hosts. Infection of a dog with D repens was first reported in Palestine in 1934, and 2 additional cases were reported in dogs in Israel to date. This report describes D repens infection in 4 dogs in Israel that presented with subcutaneous masses, which were cytologically characterized by marked mast cell and eosinophil infiltration. In 3 cases, multiple microfilariae were present in the lesions; rare microfilariae were present in the 4th case. In all 4 dogs, PCR of fine‐needle aspirates from the lesions were positive for D repens. The mast cells observed in all lesions were uniform and highly granulated, and with the presence of the microfilariae, a mast cell tumor was considered less likely. This report suggests that D repens infection‐associated subcutaneous lesions, characterized cytologically by massive mast cell and eosinophil infiltration, should be considered a differential diagnosis for mast cell tumor, especially in geographic locations endemic for this nematode. Notably, all 4 dogs were infected with D repens despite a routine prophylactic doramectin therapy administered every 3 months, probably due to the relatively long time interval between treatments. 相似文献

This report describes an 11‐year‐old Percheron mare that presented with signs of colic and was ultimately diagnosed with bacterial peritonitis of unknown origin. Bacterial culture of a peritoneal fluid sample isolated 2 Clostridial species, one of which was strongly suspected to be Clostridium haemolyticum. The horse was markedly hypoalbuminaemic at presentation, leading to the development of low oncotic pressure and ventral oedema. The mare was administered a low molecular weight/low molar substitution hydroxyethyl starch solution in conjunction with other therapies that resulted in marked improvement of clinical signs. The purpose of this report is to describe the clinical findings associated with equine peritonitis associated with C. haemolyticum, a rarely identified pathogen in the horse. Secondly, this report serves to describe the beneficial effects of tetrastarch administration in a clinical case with severe hypoalbuminaemia and ventral oedema. 相似文献

This report concerns a collection of parasitic worms from South Africa, and contains a new species of monogenean, Gyrodactylus transvaalensis, six species of adult trematodes, including a new species of Phyllodistomum.P. van der waali, two metacercariae of the Family Clinostomidae and three of the Order Strigeida, as well as two species of cestodes, and larvae of the nematode genus Contracaecum. The adults of previously-known helminths are redescribed, with some remarks on their systematics and biology. Accompanying the material of the new gyrodactylid monogenean there is a specimen which is thought to be a giant of the new form, and this appears to be the first recorded suggestion of the occurrence of gigantism in the Monogenea, and in fact in any kind of helminth. 相似文献

Mycobacterial infections are rare in equines. Mycobacterium bovis (M. bovis) is an important zoonotic bacterial pathogen causing disease in a wide range of animal species and sporadically causes severe disseminated disease in horses. This report describes the clinical, gross post‐mortem examination and histopathological findings in a case of disseminated M. bovis infection in a donkey which to the authors’ knowledge has not been previously documented in the scientific literature. 相似文献

Abstract This communication is the first report of the nematode Eustrongylides ignotus from Panama. The parasite was collected mainly from the lateral musculature and intestinal mesenteries of peacock bass (cichlid) Cichla ocellaris, caught by sport fishermen. The nematode showed a preference for larger female fish. 相似文献

This case report describes the treatment and outcome of a 3.5-month-old lame foal, with a history of pneumonia associated with Rhodococcus equi. Clinical examination identified osteomyelitis of the scapulohumeral joint. The unusual location of the Rhodococcus equi osteomyelitis unresponsive to prevention and adequate treatment led to euthanasia of the patient. Post-mortem findings confirmed bronchopneumonia due to Rhodococcus equi as well as the osteomyelitis of the scapulohumeral joint. This case highlights that Rhodococcus equi should be considered as a pathogen in extrapulmonary locations such as septic arthritis and osteomyelitis in foals with history of bronchopneumonia. Early and aggressive treatment should be considered. 相似文献

This case report describes the investigation and treatment of an adult horse with purulent, malodorous exudate originating from a large intermandibular mass. Microbial culture of fluid aspirated from a draining tract yielded Peptostreptococcus and Prevotella species which are usually considered to originate from the oral cavity. Computed tomography (CT) was used to aid in the diagnosis and to allow careful presurgical planning, and the horse underwent successful debridement of the abscess cavity under general anaesthesia. Post-operatively, the horse developed trismus (reduced opening of the jaws) but repeat CT identified that the surgery site was healing appropriately. It was recommended to continue feeding the horse hay to act as physiotherapy and the masticatory action of the horse subsequently returned to normal. 相似文献

A five‐year‐old, entire female mixed‐breed dog was presented with corneal oedema and episcleral hyperaemia in the left eye. The ophthalmological examination revealed the presence of a free‐swimming nematode in the anterior chamber. Circulating microfilariae were not observed by a modified Knott test nor were adult antigens detected in serum by a commercial ELISA. The parasite was surgically removed from the dog's eye, but its anterior end was damaged during the surgery. Based on the morphology of the posterior end, the nematode was preliminarily identified as a male Dirofilaria immitis. The species identification was confirmed by PCR amplification and sequencing of the mitochondrial coxI and 12S rDNA genes, using a DNA barcoding approach. Although other cases of ocular dirofilariosis by D. immitis have been previously recorded in Australia and the United States, the case reported herein is the first in a dog from Europ. 相似文献

This report describes the clinical, biochemical and histopathological findings of a case of disseminated, primary mycobacterial infection with Mycobacterium bovis in a pony presenting with neurological signs and weight loss. This report revisits tuberculosis as a potential differential diagnosis in horses at a time of relatively strong tuberculosis control in the UK and iterates the importance of post‐mortem examination as a diagnostic tool for clinicians. Key public health questions following exposure to mycobacterial pathogens are also discussed. 相似文献

Scrotal enlargement is a problem in stallions that often leads to poor semen quality. Although there are many causes for scrotal enlargement, testicular neoplasia is often high on the differential list, especially in an aged stallion. This case report describes a stallion with scrotal enlargement caused by a rare neoplasia located in the tunica vaginalis, and not in the testicular parenchyma. Diagnosis of mesothelioma was made following hemicastration. Prognosis in other species is variable, but this stallion returned to his successful breeding career following treatment and has remained healthy one year following the diagnosis. 相似文献

Primary peritonitis in horses attributable to Actinobacillus equuli has been reported in Australia, New Zealand and North America. Published reports describe a rapid response to treatment with appropriate antimicrobial and supportive treatment and an excellent prognosis for survival. To our knowledge, this is the first reported case of Actinobacillus capsulatus in the horse. The case was complicated by the development of an idiopathic chylous abdominal effusion. The report highlights the importance of molecular methods in the correct identification of bacterial species. Prognosis for horses diagnosed with Actinobacillus peritonitis may be guarded given the atypical response to appropriate antimicrobial treatment in this case. 相似文献

Habronemiasis, otherwise known as summer sores, is a parasitic disease of horses, donkeys and other equids, commonly encountered in subtropical and tropical regions. It occurs as a result of nematode infestation of the skin and typically manifests as ulcerative granulating lesions or masses. Habronema muscae, Habronema microstoma and Draschia megastoma are the usual invaders, usually transmitted by house flies, face flies and stable flies. In this case report, an eosinophilic granuloma on the urethral process of a 15-year-old gelding is presented, followed by successful surgical excision without further medical treatment. To the authors’ knowledge, equine eosinophilic granuloma on the urethral process associated with habronemiasis has not previously been documented in southern Europe and should be considered as a potential differential diagnosis for penile masses. 相似文献

This report describes the first isolation of Moellerella wisconsensis from the lung of a goat in Italy and represents the fourth isolation of this rare enterobacterial species from non-human sources reported in the literature. In fact, since its first isolation, M. wisconsensis has only been described in a few other occasions and often in clinical samples associated with cases of human enteritis. 相似文献

This report describes the use of thoracoscopy in 2 horses to obtain an antemortem diagnosis of thoracic lymphoma. The first horse in this report presented for assessment of weight loss and fever of unknown origin. The second presented with a history of upper respiratory tract noise and coughing during exercise. Although a strong clinical suspicion of neoplasia existed, a definitive antemortem diagnosis of thoracic lymphoma was not made in either case until biopsy samples obtained during standing thoracoscopy were examined. 相似文献

Nematode infections are a serious constraint to pig production, especially where free range pig keeping is practiced. This
study investigated the epidemiology of nematodes in free range pigs in Busia District, Kenya. Three hundred and six pigs from
135 farms were sampled for faeces that were analysed for nematode eggs per gram (EPG) of faeces using the McMaster technique.
The nematode eggs were also identified to genus and species based on morphology. A questionnaire on risk factors was also
administered to the pig owners. The overall prevalence and mean nematode EPG were 84.2% and 2,355, respectively. The nematode
eggs were identified as those belonging to Oesophagostomum spp. (75%), Strongyloides ransomi (37%), Ascaris suum (18%), Metastrongylus spp. (11%), Trichuris suis (7%) and Physocephalus sexalatus (3%). The prevalence of nematodes was positively correlated (p < 0.05) with the amount of rainfall in the division of the pigs' origin (all nematodes except S. ransomi). The prevalence of nematodes was also associated with the age of the pigs. A lower burden of nematodes was associated (p < 0.05) with a history of deworming (A. suum) and the provision of night housing (S. ransomi and Metastrongylus spp.). In conclusion, this study has provided information on nematode infections and the associated risk factors for free
range pigs in Busia District, which can be used when implementing integrated control measures. 相似文献

Chlamydia gallinacea is a recently described bacterial species in a genus known to infect and cause disease in animals and humans. Our report describes the identification of C. gallinacea infection in free‐range laying chickens (Gallus gallus) in Australia, and the identification of C. gallinacea infection in a parrot, a wild Australian galah (Eolophus roseicapillus). There is currently little knowledge of the effects of C. gallinacea infection on avian hosts, but it has been linked to respiratory disease in humans and could potentially cause similar disease in other species. Our report highlights the need for further study and surveillance of Chlamydia species in both wild and domestic hosts in Australia. 相似文献

From September 2008 to April 2009 several cases of spontaneous bleeding and nodules from the back and withers area of cattle otherwise considered as healthy have been reported from several farms in south-western and southern Germany. Successive investigation of these cases gave strong evidence of Parafilaria (P.) bovicola infections due to their seasonal occurrence and specific pathological lesions. There was no history of animal import from endemic countries for the affected cattle herds. In one case, a nodule containing nematode fragments and an intact female nematode were recovered from a slaughtered White Galloway bull. This sample was identified as P. bovicola and is the first report of bovine parafilariosis in Germany. 相似文献

This case report describes suspected electrocution in a juvenile female Great Horned owl (Bubo virginianus) with subsequent bilateral cataract formation. The bird flew into a high‐voltage power line and was immediately rescued. Burn wounds of the head and ataxia with apparent blindness were noted. Initial ophthalmic examination 5 days after the incident revealed bilaterally symmetrical anterior subcapsular vacuolar cataracts with absence of intraocular inflammation and a predominantly clear view to the normal appearing fundus. The bird appeared to be nonvisual. No ophthalmic medications were prescribed at initial examination. Subsequent recheck examination at 8 weeks revealed moderate resolution of the cataracts and improved vision. To the authors’ knowledge, this is the first published report of suspected electric cataracts in an avian species. 相似文献
