Background: Snakebites occur frequently among humans and animals. In Brazil, about 23,000 cases of snakebite involving humans were recorded in 2016, 11% of them caused by venomous snakes. In the region of Cuiabá, capital of Mato Grosso, the highest occurrence is of snakes of the genus Bothrops (81%), followed by Crotalus (4%). Bothrops venom has proteolytic, coagulant and hemorrhagic effects, whereas Crotalus venom is neurotoxic, myotoxic and nephrotoxic. This paper reports on three cases of Bothrops snakebites in dogs treated at the Veterinary Hospital of the Federal University of Mato Grosso in 2017.Cases: Three dogs were treated showing clinical signs of snakebite, possibly by Bothrops, since their owners reported that these are the snakes most frequently found where they live. This information is consistent with the known geographic distribution of snakes of the genus Bothrops in the state of Mato Grosso, Brazil. In the first report (Case 11), the patient was bitten on two different occasions in a five-month interval, and died presumably due to anaphylactic shock caused by the venom injected by a second snakebite (Case 12). In both episodes, the animal presented a swollen face and neck, dyspnea and eye bleeding, and these signs were more severe in the second episode. Case 2 was a dog with severe neck and chest swelling and pain. The owner of this dog reported that he had taken his dog for a walk in the countryside, along with the dog of Case 1, and had returned home with both dogs about three hours before the consultation. Case 3 was a Rottweiler living at a small family farm located 67 km from Cuiabá. The animal presented with slight swelling and pain in the left forelimb, and puncture wounds on the lower limb. Neutrophilic leukocytosis was observed in cases 1 and 3.  In addition, Case 12 (the second episode of Case 1) presented with thrombocytopenia and increased prothrombin time and activated partial thromboplastin time. The dog of Case 2 presented no hematological or biochemical alteration. All the dogs received antivenom serum and supportive care.Discussion: Based on the clinical signs of local swelling with bleeding and absence of neurological signs, the snakebites were attributed to the genus Bothrops. In Case 12, blood clotting tests showed non-coagulation. The greater severity of Case 1, which culminated in death, was attributed to anaphylaxis due to prior exposure or the larger amount of venom than that injected in Case 2, since the two injuries were inflicted in the same environment on the same day, probably by the same snake. Neutrophilic leukocytosis may be indicative of an inflammatory reaction, while thrombocytopenia and clotting changes are associated with the hemorrhagic activity of Bothrops venom. Death by snakebite is directly linked to the amount of venom injected, the envenomation site, and the time between the bite and the beginning of treatment. This explains the moderate signs presented by Cases 2 and 3, whose injuries were inflicted on the neck and forelimb, unlike the dog of Case 1, which was bitten on the head on two occasions. It was concluded that Bothrops venom causes systemic and local alterations characterized by pain, swelling, necrosis and bleeding. Early access to antivenom treatment is essential to neutralize clinical signs and prevent worsening of systemic poisoning. The determining factor in snakebite deaths is the amount of injected venom and the time elapsed between the injury and the beginning of treatment.

Dermatophyte Infection

Dermatophytosis, commonly known as ringworm, is a zoonotic disease caused by complex fungi that grow as hyphae and attach to the skin, hair and nails or claws. About 40 species of fungi of the genera Microsporum spp., Trichophyton spp. and Epidermophyton spp. are considered dermatophytes, and Microsporum canis is the genus most commonly isolated from cats. This study investigated the occurrence of dermatophytes in cats without clinical signs of skin diseases. The study involved the physical examination of 50 clinically healthy cats and the collection of samples for direct examination and fungal culture at a university veterinary hospital. The resulting data were evaluated by the chi-square association test. Of the 50 cats, 11 (22%) presented dermatophytes, with a predominance of Microsporum spp. The other 39 animals were diagnosed for non-dermatophytic fungi. Sex, breed and the presence of contactants showed no statistical difference, although there was a predominance of adult animals. The high dermatophyte infection rate confirms that cats without clinical signs can harbor these fungi, acting as asymptomatic carriers, contaminating the environment and increasing the infection rate. This study confirms that cats without clinical signs can be carriers of ringworm, which underscores the importance of the adoption of control methods even for clinically healthy animals.

Abstract Background Cutaneous and renal glomerular vasculopathy (CRGV) is a condition of unknown aetiology involving microvascular thrombosis. It has recently been described in over 160 dogs in the United Kingdom and usually has a grave prognosis. To date, this condition has not been described in dogs residing in the Republic of Ireland. Case presentation Three dogs presented to University College Dublin Veterinary Hospital (UCDVH) for investigation of rapidly progressive skin lesions. All dogs were diagnosed with CRGV on post-mortem examination. All three dogs had azotaemia on presentation or rapidly developed azotaemia, and all were euthanased because of progression of clinical signs and likelihood of CRGV. One dog was affected by seizure-like episodes and had thrombotic microangiopathy evident within the cerebrum. Conclusions CRGV occurs in dogs residing in the Republic of Ireland and is a differential for cases presenting with skin lesions and azotaemia. The histopathological lesions of CRGV can also affect the brain leading to neurological signs such as seizures. Owners and veterinarians should be aware that this condition can occur in dogs in Ireland.

Background: The uterine horn agenesis or aplasia is a rare anomaly consisting of absence or incomplete development of the paramesonephric ducts that origin the uterine horns. This change occurs during fetal formation and may occur concomitantly to agenesis of the ovary and/or ipsilateral kidney. The extra-uterine pregnancy consists of fetal growth outside the uterine cavity and can occur as a tubal or abdominal pregnancy. We report here the case of a 7-years-old mix breed dog, attended at the Veterinary Hospital of the Federal University of Mato Grosso, with accidental diagnosis of agenesis of uterine horn and ovaries and ectopic fetal mummifcation.Case: A 7-years-old mix breed dog, not spayed, was attended at the Veterinary Hospital of the Federal University of Mato Grosso (HOVET-UFMT), complaining of mucous bloody vaginal discharge. The patient had regular estrus and was multiparous. There was no mating history in the last estrus neither trauma over the past months. In previous pregnancies the patientpresented eutocic labors. On physical examination the dog showed apathy although it was alert, pale mucous membranes, presence of perivulvar blackish secretion and discreet abdominal enlargement. As preoperative exams, a complete blood count, liver and renal function (serum creatinine and alanine aminotransferase) were performed. It has also performedthe abdominal ultrasound examination, which revealed the presence of uterus flled with hypoechoic luminal content and a thickened and irregular wall. The patient was referred to therapeutic ovariohysterectomy (OHE). After anesthesia and antisepsis, the access to the abdominal cavity was made, where there was a mummifed fetus with approximately 15.5 cmfrom neck to tail set, equivalent to 57 days of gestation. After removal of the papyraceus fetus, the uterus was found and then, when exposed, there was only the left uterine horn flled by content and ovarie, both were removed. After inspection, the synthesis of the abdominal cavity was carried out as the routine. During the postoperative period, the patient had no complications or other clinical signs similar to those observed in the initial presentation. Antibiotic (enrofloxacin 5 mg/kg every 12h), analgesic (dipyrone 20 mg/kg every 8 h) and non-steroidal anti-inflammatory (meloxicam 0.2 mg/kg every 24 h) were prescribed. The fetus and uterus were sent to the Veterinary Pathology UFMT Laboratory (PVL-HOVET).The fetus was covered by omentum and fat. After the initial incision, there was a hard fbrous capsule surrounding the mummifed fetus. There were no recent signs of rupture or scarring resulting from previous trauma in the uterus. Its size was 15x4.8x2.8 cm and it was flled out with mucus bloody brownish secretion (pyometra). Microscopically, had purulent inflammatory infltrate, diffuse and severe in mucosa and submucosa associated with cell debris and moderate hyperplasia glands containing microabscesses inside.Discussion: Reports of extra-uterine fetal mummifcation in dogs and cats are scarce. Even being reported infrequently in dogs if congenital uterine and ovarian abnormalities are found during surgery, a detailed inspection of the abdominal cavity should be performed in order to rule out the possible presence of the ipsilateral ovary. Even with the lack of specifc clinical signs, fetal ectopy can be diagnosed through a detailed clinical examination and image exams. Exploratory laparotomy can be used as a diagnostic and therapeutic tool, since the treatment is the excision of ectopic tissue and OHE in cases of uterine rupture.Keywords: aplasia, fetus, mummifcation, unicornuate uterus.

ABSTRACT The population of wild animals is regulated by many biotic and abiotic factors, and parasites are a biotic factor that affects the dynamic and density of host populations. From 2002 to 2014, 62 wild animals from the biomes Pantanal, Amazon, and "Cerrado" (or Savanna), which died in attendance in the veterinary hospital or have been road-killed, underwent necropsy for parasitological examination. Overall, 36 species of parasites were identified from 24 host species. Among the parasites, the most prevalent order was Oxyurida (29.1%), followed by Strongylida (20.9%), Spirurida (19.4%), Ascaridida (16.2%), Pentastomida (3.2%), Echinostomida (3.2%), Gygantorhynchia (3.2%), Rhabditida (1.6%), Plagiorchiida (1.6%), and Monilimorfida (1.6%), especially nematodes, which have more biotic potential and is more easily adapted to the environment than other classes. The occurrence of endoparasites was observed more frequently in endothermic than ectothermic animals, and herein is reported eleven new host occurrences for endoparasites in wild animals. The study has contributed to the knowledge on the biodiversity of parasites in wild animals from three biomes in central-western Brazil.

ABSTRACT: The increasing expansion of visceral leishmaniasis (VL) in the Brazilian territory evidences the need for studies focused on the main reservoir of this parasite: the dog. This study aimed to conduct an epidemiological survey in the municipality of Barão de Melgaço, Pantanal region of the state of Mato Grosso (MT), Brazil. Conventional polymerase chain reaction (PCR) and qualitative SYBR®Green real-time PCR (qPCR) were used to diagnose canine VL (CVL) and characterize the factors associated with this infection. Of the 402 dogs that had blood samples collected, 31 presented the parasite DNA, representing a prevalence of 7.71% in the population studied. Positivity indices for PCR and qPCR were 3.48 (14/402) and 7.21% (29/402), respectively. Comparison of the results obtained by both techniques showed moderate agreement (Kappa = 0.5364). Of the independent variables analyzed, presence of clinical signs (p≤0.05) was the only one associated with CVL. Based on this study, we conclude that VL is a circulating disease, with relatively low prevalence, in dogs of Barão de Melgaço/MT, and that the presence of clinical signs is the only variable associated with canine infection.

The occurrence of hypocalcemic tetany in seven newly born infants is described. Six of the infants were born to mothers with a history of diabetes mellitus. The mother of the seventh infant was obese and had a prediabetic type of glucose tolerance curve. Clinical signs of tetany appeared within 24 hours of birth. They were severe in five infants and mild in two. Chemical findings in the blood are summarized. All seven infants were born prematurely. Diagnosis and differential diagnosis are discussed. It is considered that hypocalcemic tetany probably occurs with a significant frequency in babies newly born to diabetic mothers. It is suggested that the occurrence of hypocalcemic tetany is favored by the temporary decline which normally occurs soon after birth in the concentration of calcium in the serum, more particularly in premature babies; and that disturbance of the normal maternal hormonal adjustments of pregnancy and especially of adrenopituitary function in diabetic mothers, may be a determining factor.

ABSTRACT: Poisoning of cattle by plants of the Senecio genus represents an important cause of death in cattle and has important economic repercussions in southern Brazil. This review is intended to provide a detailed review of Senecio spp. intoxication in cattle and addresses issues regarding the toxic principle and pathogenesis of the disease caused by these plants and the epidemiology, clinical signs, diagnosis, control and prophylaxis of the disease. Senecio brasiliensis is the main species associated with natural intoxication of livestock in Brazil, and the number of cases associated with the ingestion of S. madagascariensis is increasing. The toxic principle of Senecio spp. comprises the hepatotoxic alkaloids of the pyrrolizidine group (pyrrolizidine alkaloids, PAs). The resulting liver lesions are chronic and irreversible and result from the inhibition of hepatocellular mitosis. Deaths of adult cattle may occur both sporadically and in larger outbreaks over an extended period of time. In cattle raising, Senecio spp. are consumed mainly during the winter, when there is a dearth of forage; at this time the poisonous Senecio species are budding and contain high concentrations of PAs. Spontaneous Senecio spp. intoxication in cattle is a chronic condition that frequently involves acute clinical manifestations. Affected cattle may present ascites, emaciation, intermittent dark diarrhea, tenesmus, rectal prolapse, and neurological signs resulting from hepatic encephalopathy. Hepatogenous photosensitization may be observed but is uncommon. Necropsy findings include dependent subcutaneous edema, ascites, and edema of the mesentery, abomasal folds, and gallbladder. The liver is firm, normal or reduced in size with a white, thick capsule. Microscopically, the hallmarks of Senecio-associated disease are varying degrees of hepatocellular megalocytosis, bile duct hyperplasia and fibrosis. Sheep are significantly more resistant to Senecio intoxication than are cattle and avidly ingest Senecio plants; therefore, the use of sheep for grazing infested pasture is recommended for preventing the associated disease in cattle.

In many electroconvulsive therapy centres atropine is used to mitigate adverse effects resulting from stimulation of the parasympathetic nervous system, while the violence of muscular contractions is controlled with a muscle relaxant. It is customary to secure hypnosis with a short acting barbiturate prior to administration of the relaxant. The first report of the use of thiopentone for E.C.T. was by Rubinstein (1945), and methohexitone (Lilly 25398) was introduced by Friedman (1959). The use of succinylcholine (iodide) for E.C.T. was first reported by Holmberg and Thesleff (1951). The neurological signs during unmodified E.C.T. have been well documented (e.g. Klein and Early, 1948a, 1948b, 1949; Kalinowsky and Hoch, 1952). There is as yet no comparable detailed clinical description of E.C.T. when modified by atropine and a short acting muscle relaxant preceded by a barbiturate. This discussion is limited to some of those signs which may be of assistance in the management of therapy.

The aim of this research was to investigate natural hemoplasma infection in cats treated at the Veterinary Hospital of the Federal University of Mato Grosso, and the factors associated with infection. Blood samples from 151 cats of different sexes, breeds, and ages were analyzed by PCR and blood count. The overall occurrence of hemoplasma was 25.8%. Mycoplasma haemofelis (Mhf), ‘Candidatus Mycoplasma haemominutum (CMhm)’, and ‘Candidatus Mycoplasma turicensis’ (CMt) were observed in 15.2%, 14.6% and 2.6% of cats, respectively. In 6.6 % of cases, co-infection was observed. Male felines or mixed breed cats were associated with infection by CMhm (P = 0.02 and 0.04, respectively). The data obtained demonstrated an occurrence of 25.8% for hemoplasma infection in felines coming from clinical care in the city of Cuiabá, where males were at higher risk of acquiring the infection by these agents, in addition to a higher risk for CMhm in felines with no specific breed.

A 12 yr old female neutered Carthusian crossbreed cat was presented due to progressive neurological signs. Clinical signs included dehydration, stupor, and anisocoria. Laboratory examination revealed severe hypernatremia, azotemia, hyperglobulinemia, and an erythrocytosis. Clinical signs and hypernatremia suggested an intracranial process. Imaging studies revealed a loss of structure in the cerebrum, hypothalamus, and pituitary gland. Due to a poor prognosis, the cat was euthanatized. Histopathological examination revealed a subacute granulomatous and necrotizing panencephalitis with Toxoplasma-typical protozoa. The Toxoplasma-induced dysfunction of the hypothalamus and pituitary gland led to diabetes insipidus, which was, in combination with insufficient water intake, the most likely cause for the hypernatremia.
