Nonsyndromic Cleft Lip and Palate in Boxer Dogs: Evidence of Monogenic Autosomal Recessive Inheritance

Four newborn boxer dogs with bilateral cleft lip and palate were examined in search of further abnormalities, but no other type of congenital defect was found. These data, along with the pedigree inspection regarding the clinical phenotype, led to the conclusion that the affected dogs had a nonsyndromic monogenic autosomal recessive cleft lip and palate.

Clinical, biochemical and haemathological effects in Rhamdia quelen exposed to cypermethrin

The acute intoxication of Cypermethrin in Silver Catfish (Rhamdia quelen) was evaluated. Animals weighing 56.67±4.43g and measuring 18.92±1.16cm were exposed to sublethal concentrations of Cypermethrin for the species in hydrological conditions during 96 hours. A total of 52 fish divided into three groups were used and received the following concentrations of Cypermethrin: 0 (n=12); 1.5 (n=20) and 2.5 (n=20)mg/L. The intoxicated animals suffered behavioral changes such as loss of balance, swimming alteration, dyspnea, upright swimming and sudden spiral swimming movements. As soon as the 96-hour period was over, a blood collection for hematological and biochemical analyses was performed. A complete haemogram test, plasmatic protein test, albumin, alanine transaminase (ALT), aspartate aminotransferase (AST), gamma glutamyltransferase and alkaline phosphatase (ALP) were studied. The values of erythrocytes, hematocrits, haemoglobin, total number of leukocytes, thrombocyte, ALT, AST and ALP changed according to the groups. The results have shown that the environmental contamination by Cypermethrin is toxic to the species.

Intratracheal therapy with autologous bone marrow-derived mononuclear cells reduces airway inflammation in horses with recurrent airway obstruction.

This research evaluated the effects of bone marrow-derived mononuclear cells (BMMCs) on the inflammatory process in the equine recurrent airway obstruction (RAO). Eight horses in RAO clinical score were divided into cell therapy group (Gcel) treated with a single intratracheal dose of BMMCs, and dexamethasone group (Gdex) treated with 21days of oral dexamethasone. The horses were clinically revaluated on days 7 and 21, together with cytological evaluation of the BALF, and detection of inflammatory markers (interleukins [IL]-10, -4, and -17, and interferon γ and α). There were decreases in respiratory effort and clinical score on days 7 and 21(p<0.05) for both groups. The percentage of neutrophils decreased and macrophages increased on days 7 and 21 (p<0.005) in both groups. IL-10 levels increased in the Gcel group on day 21 compared to days 0 and 7 (p<0.05), but this was not observed in the Gdex group. The quantification of IL-4, IL-17, IFN-γ, and IFN-α did not change between evaluations in both groups. These preliminary results suggest that BMMCs may ameliorate the inflammatory response of RAO.

Evaluation of Toxicity in Silver Catfish

The pollution of rivers and lakes with chemicals of anthropogenic origin may have adverse consequences: the waters become unsuitable for drinking and other household purposes, ir‐ rigation, and fish cultivation, and the animal communities living in them may suffer serious‐ ly. Massive fish kills are recorded rather frequently, and changes in the population of the fauna as a consequence of sublethal effects on ecologically important species have also been described (Koprocu; Aydin, 2004).

Comparison of two surgical techniques for creating an acute myocardial infarct in rats

OBJECTIVE To perform a comparative assessment of two surgical techniques that are used creating an acute myocardial infarc by occluding the left anterior descending coronary artery in order to generate rats with a left ventricular ejection fraction of less than 40%. METHODS The study was completely randomized and comprised 89 halothane-anaesthetised rats, which were divided into three groups. The control group (SHAM) comprised fourteen rats, whose left anterior descending coronary artery was not occluded. Group 1 (G1): comprised by 35 endotracheally intubated and mechanically ventilated rats, whose left anterior descending coronary artery was occluded. Group 2 (G2): comprised 40 rats being manually ventilated using a nasal respirator whose left anterior descending coronary artery was occluded. Other differences between the two techniques include the method of performing the thoracotomy and removing the pericardium in order to expose the heart, and the use of different methods and suture types for closing the thorax. Seven days after surgery, the cardiac function of all surviving rats was determined by echocardiography. RESULTS No rats SHAM group had progressed to death or had left ventricular ejection fraction less than 40%. Nine of the 16 surviving G1 rats (56.3%) and six of the 20 surviving G2 rats (30%) had a left ventricular ejection fraction of less than 40%. CONCLUSION The results indicate a tendency of the technique used in G1 to be better than in G2. This improvement is probably due to the greater duration of the open thorax, which reduces the pressure over time from the surgeon, allowing occlusion of left anterior descending coronary artery with higher accuracy.

Mycotoxins in dry-cured meats: A review

Dry-cured meats products are consumed in various regions of the world and, consumers are increasingly demanding better quality and safety of these products. Some fungal species can produce mycotoxins in drycured meats, such as aflatoxins and ochratoxins, which, when ingested, can produce carcinogenic and mutagenic effects in humans. Contamination of these products can occur at different points of the production chain, from the field (animal contaminated with feed) to the production or storage of the final product. Although the presence of mycotoxins in drycured meats has been reported in several regions of the world, the presence of these contaminants are not legislated in most countries. Therefore, it is important to put in place methods to identify and reduce the contamination of dry-cured meats, minimizing the consumption and deleterious effects caused by mycotoxins. This review aimed to describe mycotoxin-producing fungi, mycotoxins, the relationship between human food and animal feed; legislation; incidence, identification and control methods for mycotoxins in dry-cured meats intended for human consumption.

Use of Staphylococcus aureus Phage Lysate Staphage Lysate (SPL)® for the Control of Recurrent Pyoderma Eczema in Dogs with Atopic Dermatitis

Background: Recurrent staphylococcal infections are frequent in dogs with atopic dermatitis (AD). Many factors seem to contribute to making bacterial pyoderma refractory to treatment. Short-term systemic antibiotic therapy is effective for the treatment of acute symptoms, and may, along with pulsatile therapy, contribute to the long-term control of the disease. However, microbial resistance has become a growing and alarming problem. The aim of this study was to evaluate whether the use of Staphylococcus aureus Phage Lysate Staphage Lysate (SPL)®, can minimize the symptoms of recurrent pyoderma and increase the interval between acute atopic manifestations in dogs. Materials, Methods & Results: Thirteen dogs with a history of Canine Atopic Dematitis (CAD) and recurrent bacterial pyoderma received SPL at increasing intervals for 23 weeks. The contents of an intact pustule of each dog was collected and submitted to microbiological analysis. Systemic antibiotic therapy was established for the first 4-6 weeks of SPL protocol, based on the antibiotic sensitivity tests. The animals included in the study underwent a therapeutic protocol receiving shots of 0.5 mL of SPL subcutaneously (SC) twice a week for the first 12 weeks; 1.0 mL of SPL (SC) once a week for four weeks; 1.0 mL of SPL (SC) once every 15 days; 1.0 mL of SPL (SC) after a three-week interval from the last dose on week 20, until final observation at week 26, with no application. The animals underwent clinical examination every week and the evaluation of pruritus was used according Rybnicek et al. During the therapeutic protocol with SPL, a significant decline in the pruritus was observed in the treated dogs (P < 0.05). In week 1, the mean pruritus index was 7.33 on the Rybnicek scale; in weeks 12 and 23, the mean indices were 2.41 and 1.91. An effectiveness of 83.33% for the control of pruritus along with regression of the lesions was observed. Discussion: Before treatment, the selected animals presented worsening of the pruritus during the pyoderma eczema episodes (pruritic), resulting in the emergence of a vicious cycle where the pruritus induced the appearance of new lesions, requiring the use of antibiotics for a long period. During the therapeutic protocol with SPL, a significant decline in the pruritus was observed in the treated dogs. The control of pruritus associated with pyoderma eczema of the dogs in this study before the vaccination protocol with SPL was satisfactory when they were subjected to antibiotic therapy; however, after suspending therapy, the bacterial infections recurred, on average, after 2-4 weeks. On the other hand, with the use of SPL, the animals were recurrence-free until the end of the experimental protocol. This was attributed to the antibiotic therapy administered at the beginning of the protocol, as this led to a regression of the bacterial pyoderma and involution of the lesions. However, after suspending antibiotics, it was observed that, by the end of the study, 83.33% of the dogs still had a low level of pruritus, few or no lesions, which were considered acceptable to most owners. At this moment none of these patients needed to be subjected to antibiotic treatment. The sums of the scores for the dogs on weeks 1, 12, and 23 were 53.33, 4.41, and 3.5, respectively, indicating significant improvements of the lesions, showing that the proposed protocol with SPL was able to prevent new episodes of pyoderma.

Cleft Lip and Palate in the Dog: Medical and Genetic Aspects

The same types of cleft lip and/or cleft palate (CL/P) that affects humans also naturally affect dogs. Therefore, the dog has become an important spontaneous animal model for the study of human oral clefts. In order to provide an overview of CL/P in dogs to people with an interest in this area, we present in this chapter the main medical aspects, ranging from the etiology to the prevention, and also the main genetic aspects, including inheritance mechanisms and highlighting the homology between the two species, and the most recent molecular findings.

Percepção e atitudes de amostra populacional sobre guarda responsável, zoonoses e cães em vias públicas

This study aimed to evaluate the perception of responsible custody, zoonosis, population control of cats and dogs and the situation of stray dogs in a sample of people belonging to the Pontifical Catholic University of Parana. For this online questionnaires with 22 questions was sent. 239 people participated in this survey, the majority were female, aged between 25-35 years with complete living mainly in Curitiba / PR higher education. They had a dog or cat as a pet, 57% of respondents, and relative to the amount of animals responding by, the average number of dogs was 2.62 ± 1.35 and 1.56 ± 1.07 for cats. Both dog owners like cats, practicing regularly said vaccination administration of wormers and vet care for their animals. The access of the street dogs was held with collar and leash by 50.53% of respondents. Regarding zoonosis, 62% claimed to know what it is and managed to cite an example. About the presence of loose animals in your neighborhood, 78% of respondents said yes, 49% noted that there stray dogs that are kept by someone, and 71% stated that the responsibility for controlling these animals should be the government and society. Given the responses, we found that this sample population recognized six types of zoonosis, realized the importance of responsible dog guard and cats and stated that there is no single responsible for stray dogs.

Pierre Robin Sequence: A Familial, Clinical, and Pathoanatomical Record of an Affected Dachshund

This study describes a spontaneous case of Pierre Robin sequence in a nonhuman animal species. A miniature dachshund with micrognathia developed glossoptosis, respiratory distress, dysphagia, temporomandibular ankylosis, and a misaligned upper jaw. The severity of this condition resulted in death by obstructive apnea at the age of 8 mo. Dogs with Pierre Robin sequence can provide further knowledge and a greater understanding of this abnormality, leading to better management of affected individuals and improvement of therapeutic methods.
