A 5-hour-old, premature alpaca cria was presented with failure to nurse, weakness, hypoglycemia, hypercapnia, and respiratory distress. The cria was treated with 3 doses of fresh, crude equine surfactant, positive pressure ventilation, and supplemental intranasal oxygen. Recovery to discharge was uneventful, and the cria regained apparently normal respiratory function. Three years after hospital discharge, the alpaca was a healthy adult. 相似文献

A 3-day-old male alpaca cria was presented for lack of vigor and failure to urinate since birth. Based on the history, laboratory data, ultrasonographs, surgical findings, and postmortem examination, the cria was diagnosed with bilateral renal agenesis and hypoplastic bladder, a congenital condition rarely seen in veterinary medicine. 相似文献

A 5-day-old Huacaya alpaca cria (Vicugna pacos) was euthanized due to deteriorating health. At birth, the cria had ophthalmologic abnormalities, but had appropriate mentation. At 2 days of age, the cria gradually stopped suckling and began to circle. At 5 days old, the owner elected euthanasia due to declining clinical condition. Grossly, the right iris had a scalloped pupillary margin, and the right olfactory bulb was malformed. Histopathology revealed persistent hyperplastic primary vitreous bilaterally and iridal abnormalities, as well as aplasia of the olfactory ventricle, olfactory tract, and olfactory foramen on the right side. 相似文献

Listeria monocytogenes was found to be the cause of fatal suppurative meningoencephalomyelitis in a 3.5-month-old cria. The cria initially had clinical signs of unilateral peripheral vestibular disease, but on the following day, the cria developed progressive signs of encephalitis. Treatment with antibiotics, flunixin meglumine, and anticonvulsant drugs failed to stop progression of the disease, and the cria was euthanatized. Post-mortem examination revealed otitis media-interna and diffuse suppurative meningoencephalomyelitis. Listeria monocytogenes was isolated from CSF and brain tissue. 相似文献

This is the first German case report of an alpaca cria suffering from a congenital vulvahypoplasia. Symptoms, diagnostics and therapy are described. The 24-hours-old cria was referred to the hospital due to reduced general condition and colic. The existent vulvahypoplasia led to impaired urination, causing further complications such as urovagina and urinary stasis up to the renal pelvis. Surgical construction of the rima vulvae cured the cria. As indicated by several cases published on the clinical picture of vulvahypoplasia during recent years, this congenital deformation could become an increasing problem in the alpaca population. 相似文献

A 4-day-old alpaca cria presented for inappetence that responded to symptomatic treatment. The cria re-presented with acute signs of inappetence and azotaemia. The azotaemia persisted despite intravenous fluid therapy. There was no right kidney on ultrasound and there appeared to be perirenal oedema around the left kidney. A diagnosis of right renal agenesis and acute renal failure of the left kidney was made. The cria failed to improve and was euthanased. Necropsy examination confirmed right renal agenesis and agenesis of the right ureter and right renal artery. A section of left kidney submitted for histological examination revealed diffuse, acute, marked tubular degeneration and nephrosis. The cause of the renal failure in the left kidney was not determined. 相似文献

A 5-month-old alpaca cria was examined for chronic poor growth and repeated episodes of diarrhea. Examination of feces for parasites yielded negative results. Serum bile acid and blood ammonia concentrations were high. Subsequent examination by ultrasonography, percutaneous splenic portography, and colonic scintigraphy did not reveal evidence of a portosystemic vascular anomaly. Exploratory celiotomy with mesenteric vein portography revealed a colonic vein shunt in the caudal portion of the abdomen from the caudal vena cava to the portal vein. The shunt vessel was ligated without incident. Following surgery, the cria began to gain weight and was more alert. Eighteen months after surgery, the cria was doing well, although it had loose feces and was slightly small for its age. Portosystemic shunts are rare in cattle and horses but should be considered in alpacas with chronic poor growth when parasitism has been ruled out. 相似文献

A 6‐month old female alpaca cria presented to The Ohio State University for evaluation of a cardiac murmur. Echocardiography revealed a left‐to‐right shunting patent ductus arteriosus, a restrictive left‐to‐right shunting perimembranous ventricular septal defect, and secondary moderate left atrial and ventricular dilation. Aortic root angiography demonstrated a type IIA patent ductus arteriosus (PDA). Interventional closure of the PDA was successfully performed, without complication, using an Amplatz canine duct occluder. This case report describes the materials and methods used for interventional closure of a PDA in an alpaca cria. 相似文献

Meningoencephalitis and brain abscessation due to Escherichia coli in a 2 week old alpaca cria 总被引:1,自引:0,他引:1
An alpaca cria which received insufficient colostrum, presented with lethargy, anorexia, no passage of faeces and neurological signs. Differential diagnosis included neonatal septicaemia, meningitis and gastrointestinal obstruction. The cria died despite treatment. Necropsy revealed brain abscesses with Escherichia coli in pure culture. The importance of the amount and timing of colostrum intake is discussed. 相似文献

An alpaca and a llama in late stages of gestation were evaluated for lethargy, anorexia, and recumbency. Both camelids had cloudy, white, turbid serum, elevated serum triglyceride (1564, 5658 mg/dL, respectively) and cholesterol (158, 297 mg/dL, respectively) concentrations, and ketonuria. Signs of fetal stress were evident ultrasonographically in the alpaca, and a live cria was delivered by Cesarean section performed under general anesthesia. The alpaca developed severe metabolic acidosis, hepatic lipidosis, and acute renal failure secondary to renal lipidosis and died 36 hours after admission despite medical therapy. Histopathology revealed renal and hepatic lipidosis and neutrophilic pancreatitis. The cria died 72 hours after birth. The llama responded to IV electrolyte, dextrose, and regular crystalline insulin therapy. The pregnancy was maintained, and the llama was discharged from the hospital 20 days after admission. Two months after discharge, the llama gave birth to a live, 5 kg cria. Findings of hypertriglyceridemia, hypercholesterolemia, elevated sorbitol dehydrogenase activity, metabolic acidosis, azotemia, and ketonuria occurred in these two camelids. Based on this report, camelids appear to be similar to both horses and cattle in their response to severe energy imbalances in late gestation. 相似文献

Cryptosporidiosis was investigated on two alpaca (Lama pacos) holdings in the South-West of England. Diagnosis was initially confirmed in a cria with diarrhoea from each holding. Cohort faeces samples were subsequently collected and examined for presence of Cryptosporidium oocysts by immunofluorescence microscopy. On the first holding, 30 samples (24 adults, 6 crias) were tested, and oocysts were detected in three of the cria samples but in none of the adults. On the second holding, 14 floor faeces samples representing apparently healthy crias and one faeces sample from a cria with diarrhoea were collected. Oocysts were detected in four of the "healthy" faeces samples and the sample of diarrhoeic faeces. All isolates were confirmed as Cryptosporidium parvum using polymerase chain reaction restriction fragment length polymorphism of the cryptosporidium oocyst wall protein (COWP) and ssu rRNA genes. Sequence analysis of a 741bp region of ssu rDNA was carried out on nine of these and revealed high sequence homology with previously reported C. parvum isolates. This investigation highlights the possibility of alpaca crias subclinically shedding oocysts, which has implications for epidemiology and transmission in animals as well as raising zoonotic concerns for human contacts. Gene sequencing of UK isolates from South American camelids is also described for the first time. 相似文献

A 12-week-old female alpaca cria weighing 10 kg presented with a 2-month history of left hindlimb lameness associated with osteomyelitis and sequestration of the shaft and wing of the left ilium. The affected segment of the ilium was surgically removed. Bacteriological culture revealed a small number of mixed aerobic and anaerobic bacteria. The cria recovered well, was discharged from the hospital 8 days after surgery and was paddock sound without complications 8 months later. Osteomyelitis and sequestration of long bones has been reported in alpacas, but further investigation is necessary to define the prevalence and pathogenesis and to develop specific recommendations for prevention and treatment. 相似文献

Blood smear examination in a 4-day-old alpaca revealed massive erythrocyte parasitism by Mycoplasma haemolamae. Blood collected from both the nonparasitemic dam and the cria were positive for M. haemolamae by polymerase chain reaction (PCR) analysis. These findings suggest in utero transmission of M. haemolamae in camelids, even when the dam is not parasitemic. 相似文献

Obstetrical care of the llama is very similar to other food animal and equine obstetrics. Understanding the few unique llama characteristics such as birthing from a standing position, no licking of the neonate by the mother, and the epidermal membrane covering the newborn, help give confidence when treating llamas. Dystocia is rare in the llama but when veterinary assistance is required, understanding the shape of the female pelvis aids in manipulations. Llama neonatal care is minimal for the healthy cria, but intensive care of a compromised cria is extremely demanding, and not always rewarding. The suggestions presented in this article are the result of 4 years' experience in providing care to many ill neonatal llamas. Several methods have been adapted from equine neonatal medicine used at the Veterinary Medical Teaching Hospital at the University of California. Basic physiological information concerning llama neonates, healthy and ill, is still being investigated. It is judicious to identify and discuss congenital problems in neonates prior to intensive support. 相似文献

A 6-hour-old alpaca cria was admitted for evaluation of respiratory distress since birth. Contrast radiography confirmed the presence of bilateral choanal atresia, and computed tomography (CT) evaluation was planned to aid in the surgical treatment. Due to deterioration in the cria's condition, euthanasia was performed prior to the CT examination. Postmortem CT examination was performed to determine the appearance of choanal atresia. The embryology and CT appearance of choanal atresia is discussed. 相似文献

A 3-mo-old male llama was examined because of a 4-wk history of lethargy and ill thrift. Clinical examination revealed subcutaneous masses in the left prescapular and right inguinal regions, mild ataxia, a slight head tilt to the right, and right ear droop. The cria died before clinical workup was complete. At autopsy, there was generalized lymphadenomegaly, a hepatic nodule, a midbrain mass causing rostral compression of the cerebellum, and internal hydrocephalus. Microscopic findings included pyogranulomatous lymphadenitis, meningoencephalitis, hepatitis, and bronchopneumonia. Intralesional fungal spherules, most consistent with Coccidioides spp., were identified in the lymph nodes, lung, and brain. Fungal culture, single-nucleotide variation genotyping real-time PCR, and DNA sequencing confirmed Coccidioides posadasii. The dam of the cria was native to Arizona and had been moved to Missouri ~2.5 y previously. Agar gel immunodiffusion assay of the herd revealed that only the dam was positive for Coccidioides spp.; 6 herdmates were negative. Computed tomography of the dam revealed multiple nodules within the lungs and liver, which were presumed to be an active coccidioidomycosis infection. This case of systemic coccidioidomycosis in a llama native to Missouri was presumably acquired by vertical transmission from the dam. 相似文献
