Background: Although the etiology of hepatogenous photosensitization has not yet been fully elucidated, it is known that hepatotoxic substances (saponins) present in grasses of the genus Brachiaria spp. are responsible for intoxication of several species, causing great economic losses in the whole world. Since this grass is the source of food for the herd in Brazil, and other countries of the world, the aim of this paper is to describe the epidemiological, clinical, laboratory and anatomopathological aspects of a steer with this disease.Case: A 3-year-old Nellore steer was referred to veterinary care at a property in Bahia, with a 3-week history of swelling, loss of cutaneous tissue in the ear and scrotum region, and dry faeces. The animal was raised in pasture with Brachiaria decumbens along with five animals of different age and sex; however, it was the only one to present symptoms. Although the animal had been treated at the farm, there was no clinical improvement. On clinical examination, the steer was apathetic with jaundiced mucous membranes, nasal and ocular discharge, epiphora, and ulcers on the labial and gum commissure. The steer had leukocytosis with neutrophilia, anemia, and hyperfibrinogemia. The body condition score (BCS) was 3 (BCS ranges from 1 to 9), and the skin lesions observed were bedsores, necrosis and scabs in several regions. The increase in liver enzymes (GGT, AST) indicated hepatic impairment, suggesting a case of hepatogenous photosensitization. The therapeutic protocol instituted was enteral hydration, electrolyte replacement, topical application of ointment in the injured areas. In addition, it was recommended to maintain the animal in the shade, supply of good quality grass, and a new clinical evaluation in seven days. On new examination, it was observed that there was no satisfactory clinical improvement of the animal, and persistence of laboratory changes. Despite the poor prognosis, treatment was continued for another month with the same recommendations. However, in view of the severe clinical condition and unfavorable prognosis, the animal was submitted euthanasia. Necropsy revealed extensive areas of bedsores, erythema, severe jaundice in the mucous membranes, eyeballs and opaque corneas. The liver had an enlarged volume with bulging edges and a greenish color. The kidneys had a pale brownish color, with an irregular and mottled subcapsular surface, with blackened and depressed spots. Histologically, the cytoplasm of the hepatocytes was finely vacuolated, sometimes refringent and with an abundant presence of bile pigment. It was also observed in the middle of the liver parenchyma, multiple foci of accumulation of macrophages filled with vacuoles of different sizes containing saponins and crystals of saponins inside bile ducts. Furthermore, it was possible to observe hypertrophy and hyperplasia of Kupffer cells, disarrangement of hepatocytes with individual necrosis of hepatocytes.Discussion: The diagnosis of hepatogenous photosensitization was based on history, clinical, laboratory and anatomopathological findings. Serum biochemistry was important to measure hepatic impairment and possible secondary lesions, which were confirmed by the necropsy. Although hepatogenous photosensitization is less common in adult cattle, it must be considered in the differential diagnosis of skin lesions, reduced appetite, and jaundice. Since it was a sporadic case, individual predisposition is probably a preponderant factor. Keywords: cattle, photodermatitis, intoxication, liver injury, skin lesions.

Abstract Background Scabies, caused by infestation of the mite Sarcoptes scabiei, is one of the most severe ectoparasitic diseases in rabbits. Scabies seriously affects the commercial rabbit breeding, causing severe economic losses. Host resistance to S. scabiei is an important factor in further development of the rabbit industry. In the present study, we compared the host resistance to S. scabiei var. cuniculi of a new breed of domestic rabbit propagated by the Sichuan Animal Sciences Academy (QiXing rabbit, QX) compared with that of a traditional rabbit breed in the domestic rabbit industry (IRA rabbit, IRA). Methods Both QX and IRA rabbits were experimentally infested with live S. scabiei var. cuniculi mites for 48 h. Then, during the course of four-week experimental infestation period, the body weight of rabbits was recorded every two weeks for calculating body-weight variations in comparison to the non-infested control rabbits. Skin lesions in the foot area were assessed on weekly basis and serum samples were tested weekly for the estimation of changes in the total antibody levels (IgG, IgE and IgM). Moreover, DNA extracted from the blood samples was amplified for analysis of the genetic diversity in the major histocompatibility complex, class II, DQ Alpha (MHC-DQA) gene. Results Compared to the IRA rabbits, the QX rabbits showed a significantly higher (P < 0.05) relative body weight gain compared to the non-infested control rabbits and significantly lower (P < 0.05) scores for foot skin lesions and higher levels of IgG, IgE and IgM at weeks 1 to 4, week 2 and week 1 post-infestation, respectively. Furthermore, a polymorphism site at position 103 bp of exon two of MHC-DQA gene and a different gene frequency were found between two rabbit breeds, suggesting the genetic basis for the differential host resistance to the S. scabiei var. cuniculi between two rabbit breeds. Conclusions The QX rabbits showed higher host resistance to S. scabiei var. cuniculi compared to the IRA rabbits at the clinical, immunological and genetic levels. These results provide a reference for the breeding of rabbits with adequately improved and sustained host resistance to scabies in the domestic rabbit industry.

Sir, Saccharomyces cerevisiae is a ubiquitous yeast used as a probiotic for antibiotic-associated diarrhea prophylaxis. It is part of the normal flora of the oral, gastrointestinal, and respiratory tracts and the vaginal lining. Severe opportunistic infections due to S. cerevisiae have been reported in patients with immunosuppression with fungemia, endocarditis, pneumonia, and urinary tract infection [1–3]. Herein, we describe the first case in the literature of a skin infection with S. cerevisiae in an immunocompetent patient. A 72-year-old patient with no particular history had had pruriginous skin lesions for five years in the context of general state preservation and apyrexia. A skin examination revealed erythematous and maculopapular lesions diffused throughout the body (Figs. 1a−1d). The phaners and mucous membranes were without abnormality, and there was no adenopathy. The rest of the examination was unremarkable. The patient had been treated several times with topical and oral antifungals and dermocorticoids but without any improvement.

Detection of Orf Virus and Papillomavirus Out of Samples from Goats and Cattle which were Gathered by Multiplex PCR RomaniaThe lesions which appear on the skin and are caused by parapoxvirus, herpesviruses and papillomavirus, depending on they're gravity, can produce large economic losses. The identification of viral species with different laboratory methods can facilitate making a correct diagnostic in identifying the infectious entity. The most common encountered injuries, especially on goats and kids, have an oral location, breasts, eyes and genital and podal. On the other side on cattles infected with papillomavirus the lesions are multiple and spread all over the body. To identify the etiologic agent from goats and cattle with skin lesions, tissue samples were collected and scabs. The virus identification was made with molecural biology techniques. The PCR method revealed the viral DNA, thus identifying a portion of the B2L preserved gene which is then amplified using primers PPP1-PPP4. For papillomavirus detection, primers FAP59 and FAP 64 were used to conserve the L1 human gene, primers that can help detect other types of papillomavirus from other species. The PCR results showed that lesions from goats were made by Orf virus, a virus that belongs to the papillomavirus gene, as for cattles the bovine papillomavirus. Studies have shown that PCR is a rapid laboratory method which can be used to identify the viral agent that causes severe skin lesions.

Background: Neurosarcoidosis manifests symptomatically in 5% of patients with sarcoidosis and diagnosis can be challenging if not clinically suspected. Cerebral mass-like presentation of neurosarcoidosis rarely reported in the literature. We presented a woman with neurosarcoidosis who had a cerebral mass-like lesion which completely disappeared after medical treatment. Discussion: A 37-year-old woman with history of pulmonary sarcoidosis referred to the emergency service of our hospital with a one-month history of progressive dizziness, nausea and seeing flashing lights. At neurologic examination, numbness and weakness on the left side of the body, deviation of uvula toward the right side was seen. Cranial MRI demonstrated a 2.5x2 cm in size mass lesion which hypointense on T1 WI, heterogeneous hyperintense on T2 and FLAIR sequence with peripheral vasogenic edema and heterogeneous, irregular contrast enhancement simulating brain tumor. Also, leptomeningeal and nodular contrast enhancement was seen on brainstem, cerebellar vermis, perimesencephalic cistern and left frontal, bilateral parietooccipital sulcus. In laboratory tests; The level of serum angiotensin-converting enzyme (ACE) was 53 IU/mL (N:8-52 IU/mL) and cerebrospinal fluid (CSF) ACE was 23 IU/mL (N:0-2.6 IU/mL). CSF cytology analysis was normal. Pattern 2 oligoclonal bands were present. With these clinical, laboratory and radiological findings, cerebral involvement of sarcoidosis was suspected. Biopsy was not performed due to the high risk of morbidity caused by the deep location of the lesion.Patient was treated with methylprednisolone and Azathioprine for a month.On post-treatment control imaging; lesion disappeared completely without residual leptomeningeal and nodular contrast enhancement.Also, neurologic symptoms were decreased remarkably. Conclusion: Multi-system inflammatory disorders like sarcoidosis, can present with mass-like lesion in the brain parenchyma. While early diagnosis is important to prevent unnecessary interventions like biopsy and surgery, it is crucial to initiate the necessary treatment with the aim of recovery without sequelae. Radiological and clinical follow-up are fundamental in differential diagnosis.

Body-temperature elevations are multifactorial in origin and classified as hyperthermia as a rise in temperature due to alterations in the thermoregulation mechanism; the body loses the ability to control or regulate body temperature. In contrast, fever is a controlled state, since the body adjusts its stable temperature range to increase body temperature without losing the thermoregulation capacity. Fever refers to an acute phase response that confers a survival benefit on the body, raising core body temperature during infection or systemic inflammation processes to reduce the survival and proliferation of infectious pathogens by altering temperature, restriction of essential nutrients, and the activation of an immune reaction. However, once the infection resolves, the febrile response must be tightly regulated to avoid excessive tissue damage. During fever, neurological, endocrine, immunological, and metabolic changes occur that cause an increase in the stable temperature range, which allows the core body temperature to be considerably increased to stop the invasion of the offending agent and restrict the damage to the organism. There are different metabolic mechanisms of thermoregulation in the febrile response at the central and peripheral levels and cellular events. In response to cold or heat, the brain triggers thermoregulatory responses to coping with changes in body temperature, including autonomic effectors, such as thermogenesis, vasodilation, sweating, and behavioral mechanisms, that trigger flexible, goal-oriented actions, such as seeking heat or cold, nest building, and postural extension. Infrared thermography (IRT) has proven to be a reliable method for the early detection of pathologies affecting animal health and welfare that represent economic losses for farmers. However, the standardization of protocols for IRT use is still needed. Together with the complete understanding of the physiological and behavioral responses involved in the febrile process, it is possible to have timely solutions to serious problem situations. For this reason, the present review aims to analyze the new findings in pathophysiological mechanisms of the febrile process, the heat-loss mechanisms in an animal with fever, thermoregulation, the adverse effects of fever, and recent scientific findings related to different pathologies in farm animals through the use of IRT.

1. In a series of non-nephritic individuals the total non-protein nitrogen of the blood, determined by Folin's method, was found to lie between 15 and 43 milligrams per 100 cubic centimeters. From 50 to 60 per cent. of this was in the ammonia-urea fraction. 2. In cardiovascular disease with renal congestion, but without other renal lesion, there was no evidence of increase of non-protein nitrogen in the blood, nor of alteration of the ammonia-urea percentage. 3. In chronic nephritis with marked albuminuria and edema there was very little, if any, increase or alteration. 4. In chronic nephritis with hypertension the non-protein nitrogen was definitely increased, ranging from 40 to 180 milligrams per 100 cubic centimeters of blood. The percentage of the ammonia-urea fraction was usually higher than in non-nephritic cases. 5. Cases showing high non-protein nitrogen values were subject to rapid fluctuations in these values in the course of a few days. As a rule, clinical improvement was associated with a fall of the non-protein nitrogen figures to nearer the normal range. 6. Uremia was almost always accompanied by an increase of non-protein nitrogen in the blood, but no constant relation could be established between the degree of increase and the tendency to uremia. 7. Our cases have not yet been followed for a long enough period to admit of conclusions as to the possible relation between the degree of non-protein nitrogen retention and ultimate prognosis. 8. We believe this method to be a valuable aid in the clinical study of nephritis and that it can be readily carried out in any well equipped clinical laboratory.

ABSTRACT Norwegian or crusted scabies (N/CS) is a rare skin disease with very few cases reported in the dog or the cat. Two adult, stray dogs were admitted in our clinic with a generalized, multifocal to diffuse and nonpruritic dermatitis that was characterized by severe crusting, scaling, and ulceration. In both instances, leishmaniosis and N/CS were diagnosed by immunofluorescent antibody test serology, lymph node cytology, and skin scrapings in which high numbers of Sarcoptes mites were found. The combination of miticidal and antileishmanial treatment, supported by topical treatment and nutritional support, resulted in the complete resolution of the skin lesions and spectacular improvement of the body condition in both cases. Dog 1 eventually died from end-stage kidney disease attributed to leishmaniosis-associated glomerulonephritis, whereas the also proteinuric dog 2 remains clinically healthy. The manifestation of the rare type of N/CS in these dogs could be attributed to cell-mediated immunosuppression, which was most likely induced by leishmaniosis and malnutrition. The necessity of searching for leishmaniosis in those scabietic cases, especially in the endemic areas of leishmaniosis, is strongly recommended.

A 26-year-old male patient presented to our rheumatology clinic with pain, swelling and limitation of movement in his right ankle, and also purpuric skin lesions in the lower extremity pretibial region. He was asked questions, and he said that he had been having chronic low back pain and morning stiffness for the last few years. His physical examination revealed that he had arthritis in his right ankle, purpuric skin lesions in pretibial regions of both legs, and bilateral FABERE/FADIR positivity. The sacroiliac joint imaging and MRI revealed bilateral sacroiliitis findings, and the lateral heel imaging revealed enthesitis. HLA-B27 was positive. Skin biopsy from lower skin lesions was reported to be consistent with leukocytoclastic vasculitis. Based on clinical, laboratory, radiological, and pathological examinations, the patient was diagnosed with ankylosing spondylitis and leukocytoclastic vasculitis. Administration of corticosteroid, salazopyrin, and nonsteroid anti-inflammatory medications was started. Notable clinical and laboratory regression was observed during his checks 3 months later.

Cutaneous Cryptococcosis

Crytococcosis is the most common deep mycosis in cats, despite its rarity in the medical practice of small animals. The infectious agent of the disease is Cryptococcus sp, an opportunistic fungus that can spread throughout the body. An approximately two-year-old mixed breed cat, weighting 3 kg was presented to a private practice in the city of São Paulo, Brazil. Physical examination relealed pyogranulomatous skin lesions, mainly on the nasal planum and the second digit of the left thoracic lim. The animal presented no neurological or respiratory signs. The response to antifulgal on cutaneous lesions was favorable, but the animal did not resist a second sedation and died within twenty-eight days after starting treatment. This report shows an atypical case of cryptococcosis due to the lack of immunodeficiency.

The article presents the results of laboratory studies to assess the toxicological parameters of montmorillonite clay from the Pogadaevskoye deposit in the West Kazakhstan region in order to use them as an aluminosilicate sorbent in the composition of feeds that reduce the negative effects of mycotoxins on the body of animals and birds. The relevance of research is associated with the cultivation of healthy and highly productive animals and poultry in order to ensure the food security of the Republic of Kazakhstan.The studies carried out to assess the toxicological parameters of montmorillonite clay in order to use them as an aluminosilicate sorbent in experimental animals (rabbits and white rats) allowed the following results to be obtained: Visual study of the intensity of erythema when exposed to the test substance on the skin of rabbits showed their absence (0 points). The study of the intensity of edema (an increase in the thickness of the skin clutch of rabbits) when exposed to the test substance on the skin of rabbits showed no reaction (0 points). Studies evaluating the irritating effect of the test substances on the mucous membranes of the eyes of rabbits by symptoms of damage showed the absence of hyperemia (0 points). Weak eyelid edema (1 point), the minimum amount of discharge in the corner of the eye (1 point). The results of studies on the classification assessment of the test substance for the severity of the irritant effect on the eyes of rabbits showed that the average total score of the severity of the irritative effect corresponds to 1 point. A comprehensive analysis of the results obtained on the basis of scientific and experimental studies to assess the toxicological indicators of montmorillonite clay from the Pogadaevskoye deposit in relation to irritating effects on the skin and mucous membranes of experimental animals (rabbits) showed their harmlessness.
