J D White, N J Cave, A Grinberg, D G Thomas, C Heuer
BACKGROUND: Bacterial urinary tract infections are uncommon in cats in general but the prevalence increases to 29% in older cats with comorbidities (Veterinary Clinical Pathology 2008, 37, 317; Journal of Feline Medicine & Surgery 2007, 9, 124; Veterinary Microbiology 2009, 136, 130). Frequently, the infections are subclinical. The clinical relevance of subclinical bacteriuria (SB) is uncertain, and the optimal treatment requires clarification. OBJECTIVE: Prospective, observational study to: (i) identify the prevalence and incidence count of SB in older (≥7 years), nonazotemic cats, (ii) evaluate specific risk factors for SB, and (iii) investigate the potential relationship between untreated SB and survival...

Fungi in the genus Aspergillus are some of the most common fungal pathogens in veterinary species, primarily affecting the respiratory tract. In both human and veterinary cases, calcium oxalate crystals have been documented in sites of Aspergillus infection. Cases in multiple species (16 birds, 15 horses, 5 dogs, 1 ox, and 1 dolphin) were identified that had either positive cultures for Aspergillus sp., or had conidiophores present that could be identified as belonging to the genus Aspergillus Histologic slides were examined to confirm the presence of oxalate crystals and how often they were identified on the original report...

In human obstetrics, placental vascularisation impairment is frequent as well as linked to severe pathological events (preeclampsia and intra-uterine growth restriction) and there is a need for reliable methods allowing non-invasive evaluation of placental blood flow. Uteroplacental vascularisation is complex and animal models are essential for the technical development and safety assessment of these imaging tools for human clinical use but these techniques can also be applied in the veterinary context. This paper reviews how ultrasound based imaging methods such as 2D and 3D Doppler can provide valuable insight for the exploration of placental blood flow both in humans and animals and how new approaches such as the use of ultrasound contrast agents or ultrafast Doppler may allow to discriminate between maternal (non-pulsatile) and fetal (pulsatile) blood flow in the placenta...

BACKGROUND: Rats (Rattus norvegicus) are increasingly kept as pets, thus more and more requiring veterinary care. Important differences exist between pet and laboratory rats, but little information is available on pet rats. Diagnosis and treatment of pet rat diseases would benefit from RIs specific for this animal population. OBJECTIVES: The aim was to establish RIs for biochemical blood variables, PCV, and body temperature in pet rats. Additionally, influences of sex and feed rationing method (ad libitum, restricted) on these variables were determined...

BACKGROUND: Lactate dehydrogenase (LDH) activity is often measured in human effusions to help in differentiating between transudates and exudates. Few studies have been performed using effusion samples from animals. OBJECTIVES: The purpose of the study was to determine whether LDH can be used to differentiate between transudative and exudative effusions in dogs and cats (including postmortem samples), and whether there is a difference between different laboratory methods of LDH measurement...

Bovine Respiratory Disease is the most costly disease that affects beef and dairy cattle industry. Its etiology is multifactorial, arising from predisposing environmental stress conditions as well as the action of several different respiratory pathogens. This situation has hindered the development of effective control strategies. Although different type of vaccines are available, many currently marketed vaccines are based on inactivated cultures of the main viral and bacterial agents involved in this pathology...

The expression of tyrosine kinase receptors is attracting major interest in human and veterinary oncological pathology because of their role as targets for adjuvant therapies. Little is known about tyrosine kinase receptor (TKR) expression in canine liposarcoma (LP), a soft tissue sarcoma. The aim of this study was to evaluate the immunohistochemical expression of the TKRs fibroblast growth factor receptor 1 (FGFR1) and platelet-derived growth factor receptor-β (PDGFRβ); their ligands, fibroblast growth factor 2 (FGF2) and platelet-derived growth factor B (PDGFB); and c-kit in canine LP...

Haemorrhagic diathesis (HD) in cattle is a relatively rare syndrome that can have many different causes. With the occurrence of bovine neonatal pancytopenia (BNP) in 2007, the number of cases of HD in cattle has increased. This led to an enhanced interest in diseases presenting with bleeding disorders. The possible causes of HD in cattle, the clinical findings, and the course of various diseases are described and evaluated. Furthermore, we determined whether cases of BNP occurred before the introduction of the vaccine Pregsure BVD since its widespread use was associated with the syndrome...

REVIEW
Luca Aresu
Diffuse large B-cell lymphoma (DLBCL) is the most common canine aggressive B-cell lymphoma worldwide, and new recent molecular approaches have shown that DLBCL constitutes a heterogeneous tumor that cannot be unraveled by morphology and immunophenotype. DLBCL behaves aggressively, typically progressing over a short period of time, and the therapy response may be difficult to be predicted. Recently, the rate of bone marrow infiltration by flow cytometry has been demonstrated to be prognostic, but more sensible markers are needed...

BACKGROUND: Arthritis is an economically significant disease in lambs and is usually the result of a bacterial infection. One of the known agents of this disease is Chlamydia pecorum, a globally recognised livestock pathogen associated with several diseases in sheep, cattle and other hosts. Relatively little published information is available on the clinical, diagnostic and pathologic features of C. pecorum arthritis in sheep, hindering efforts to enhance our understanding of this economically significant disease...

BACKGROUND: The blood transcriptome can reflect both systemic exposures and pathological changes in other organs of the body because immune cells recirculate through the blood, lymphoid tissues, and affected sites. In human and veterinary medicine, blood transcriptome analysis has been used successfully to identify markers of disease or pathological conditions, but can be confounded by large seasonal changes in expression. In comparison, the use of transcriptomic based analyses in wildlife has been limited...

OBJECTIVE: Following traumatic brain injury, disruption of blood-brain-barrier and consequent brain edema are critical events which might lead to increasing intracranial pressure (ICP), and nerve damage. The current study assessed the effects of aqueous date fruit extract (ADFE) on the aforementioned parameters. MATERIALS AND METHODS: In this experimental study, diffused traumatic brain injury (TBI) was generated in adult male rats using Marmarou's method. Experimental groups include two pre-treatment (oral ADFE, 4 and 8 mL/kg for 14 days), vehicle (distilled water, for 14 days) and sham groups...
