Cantharis dissolves calculus in the ureter of a kitten: case repor

Urolithiasis is a disease thatcan occur alone or together, obstruct the urinary flow, and even progress to the animal's death. Objective:The present study is to report the dissolution of calculus in the ureter in a kitten. Methodology: a feline, SRD, male, started at 3 months old with the signs of vomiting, constipation,and hematuria, presenting leukocytosis and increased serum urea. Two abdominal ultrasounds were performed 30 days apart and the third at 3 months. Results:Inthe first ultrasound there was hydronephrosis in the right kidney and dilation of the ureter and microlithiasis in the urinary bladder. The animalhad already been treated with antibiotic therapy and did not improve. Given these characteristics, Cantharis Vesicatoria30cH was administered, there was no more hematuria and when the drug was discontinued, the symptom returned. After 30 days of startinghomeopathic treatment, we repeated the ultrasound which showed 2 kidney stones, and a urinary bladder with cystitis associated with sandy lithiasis. BerberisVulgaris30cH was then administered for 15 days, after which both drugs were discontinued and theanimal remained asymptomatic. After 3 months the ultrasound was repeated which showed 2 kidney stones, Causticum6cH was inserted for 14 days to dissolvekidney stones, thus preventing the return of the initial symptoms. Conclusion:the treatment was beneficial for the patient, who was asymptomatic after the use of Causticum.Considering the natural history of the disease in cats and the high chance of recurrence of the disease, the recommendation was to monitor the organs through an annual ultrasound examination, in addition to encouraging water intake.

Immunomodulatory effect of Bacillus toyonensis BCT-7112 supplementation in puppies vaccinated against canine parvovirus / Efeito imunomodulador da suplementação de Bacillus toyonensis BCT-7112 em cachorros vacinados contra o parvovírus canino

Bacillus toyonensis is a probiotic microorganism that for decades has been used in animal nutrition around the world. The objective of this work was to evaluate the immunomodulatory effect of oral B. toyonensis supplementation in dogs vaccinated against canine parvovirus. Puppies were randomly selected and divided in two groups, one received B. toyonensis at a concentration of 2x10 8 viable spores per day and another group without supplementation was left as control. The puppies were vaccinated against canine parvovirus type 2. B. toyonensis supplementation was efficient in stimulating specific IgG for parvovirus with titers of 2, 3, and 2.5-fold higher than controls at 7, 21, and 35 pos-vaccination days respectively. Peripheral blood mononuclear cells (PBMCs) from dogs were cultured and stimulated with B. toyonensis DNA, vegetative cell and spores. The mRNA transcription of cytokines IL-4, IL-17, and IFN-γ up modulated by the stimuli. Thus, we conclude in this study that B. toyonensis supplementation may amplify the vaccine immune response against canine parvovirus.(AU)

Bacillus toyonensis é um micro-organismo probiótico que há décadas é utilizado na nutrição animal em todo o mundo. O objetivo deste trabalho foi avaliar o efeito imunomodulador da suplementação oral de B. toyonensis em cães vacinados contra o parvovírus canino. Os filhotes foram selecionados aleatoriamente e divididos em dois grupos, um recebeu B. toyonensis na concentração de 2 × 10 8 esporos viáveis por dia e outro grupo sem suplementação como controle. Os filhotes foram vacinados contra o parvovírus canino tipo 2. A suplementação com B. toyonensis foi eficiente em estimular IgG específica para parvovírus com títulos de 2, 3 e 2,5 vezes maior que os controles aos 7, 21 e 35 dias pós-vacinação, respectivamente. Células mononucleares do sangue periférico (PBMCs) de cães foram cultivadas e estimuladas com DNA de B. toyonensis, células vegetativas e esporos. A transcrição do mRNA das citocinas IL-4, IL-17 e IFN-γ foi modulada pelos estímulos. Assim, concluímos neste estudo que a suplementação com B. toyonensis pode amplificar a resposta imune da vacina contra o parvovírus canino.(AU)

Status of Maternal Derived Antibody Against Rabies in Naive Puppies in Chennai

Thirty-six blood samples were collected randomly from puppies [18 puppies each from vaccinated (Group I) and unvaccinated (Group II) dam] brought to Immunization Unit, Madras Veterinary College Teaching Hospital, Chennai. The samples were subjected to functional antibody assay (RFFIT) to know the kinetics of maternal derived antibody (MDA) against rabies. The mean MDA titre in group I and II puppies were found as 1.07 ± 0.18 IU/mL and 0.30 ± 0.037 IU/mL respectively. The statistical analysis (Student “t” test) revealed a highly significant difference (P<0.01) between MDA of two groups. Thus, this study strongly suggests that the dogs less than three months of age in endemic regions needs to be immunized against rabies in view of maintaining the population immunity and to reduce the bioburden of rabies risk.

Vitality evaluation methods for newborn puppies after cesarean section performed under general inhalation anestesia / Métodos de avaliação da vitalidade neonatal de cães após cesariana sob anestesia geral inalatória

This study aimed to demonstrate and to correlate possible methods for neonatal assessment in dogs born by elective cesarean surgery using inhalation anesthesia, enhancing its advantages and disadvantages as well as proposing lactate measurement as an adjunctive method of evaluation. After elective cesarean surgery of four bitches subjected to morphine premedication followed by propofol induction and sevoflurane anesthesia, 30 neonates were evaluated through blood sampling from the umbilical cord for lactate measurement and blood gas analyses, as well as neurological and cardiorespiratory assessment at birth and at 10 minutes of age. The neonates presented respiratory acidosis and acidemia at birth related to blood lactate values (4.98±1.39mmol/L). Neurological and cardiorespiratory depressions were present at birth with recovery at 10 minutes and no complications were observed during the first 30 days of life. The methods for neonatal assessment used in this study are safe when appropriately interpreted and the effects of general anesthesia on neonates were transient. Blood lactate obtained from the umbilical cord can be an option for the evaluation of these patients.(AU)

Objetivou-se demonstrar e correlacionar os possíveis métodos de avaliação neonatal de filhotes de cães nascidos de cesarianas eletivas com a utilização de anestesia inalatória, apontando suas vantagens e desvantagens e propor a dosagem de lactato sanguíneo como prática auxiliar. Após a cesariana eletiva em quatro cadelas submetidas ao protocolo anestésico composto de morfina, propofol e sevofluorano, foram avaliados 30 neonatos com exames de sangue do cordão umbilical para dosagem de lactato e gases sanguíneos, avaliação neurológica e cardiorrespiratória realizadas no nascimento e aos 10 minutos de vida. Os animais apresentaram acidose respiratória com acidemia ao nascimento, associados a altos valores de lactato sanguíneo (4,89±1,39mmol/L). Ocorreu depressão neurológica e cardiorrespiratória no nascimento, com recuperação após 10 minutos, sem complicações nos primeiros 30 dias. Pode-se concluir que os métodos de avaliação neonatal utilizados são seguros quando interpretados adequadamente e os efeitos da anestesia nos neonatos foram transitórios. O lactato do sangue umbilical pode ser opção na avaliação desses pacientes.(AU)

Pharmacokinetics and clinical evaluations of gentamicin-induced nephrotoxicity in puppies.

Background: The study was aimed at investigating the effect of dosing intervals on gentamicin nephrotoxicity in puppies. Methods: Local puppies were assigned to Groups A and B (n=6) and administered gentamicin intramuscularly once (6 mg/kg) or twice (3 mg/kg) daily, respectively, for 5 consecutive days. Biochemical parameters such as urine protein, creatinine, ɤ-glutamyl transferase, as well as serum creatinine (SCR) and urea nitrogen were determined spectrophotometrically using specific kits before and after treatment. Peak and trough serum concentrations of gentamicin were determined by immunoassay on 1st and 5th day treatment. Thereafter, elimination rate constants and corresponding half-lives were calculated. Results: No significant increase in SCR concentrations in both groups was observed, but values on day 7 were slightly above normal. Conversely, there was a significant increase above normal in serum urea nitrogen on days 4 and 7 in Group A, whereas this was observed only on day 7 in Group B. Even though all other biochemical parameters assayed for were within normal, an increasing trend was noticed as the length of treatment days increased in both groups. In both groups, peak serum concentrations of gentamicin did not differ significantly. There was a 4- and 16-fold significant increase in trough levels after the last treatment in Groups A and B, respectively. Although peak and trough concentrations increased with increasing length of treatment, all the values were well below 10 μg/ml and 2 μg/ml, respectively, as required. Conclusion: These suggest the risk of nephrotoxicity following treatment with gentamicin beyond 5 consecutive days irrespective of the dosing interval in puppies.

Antígenos de secreción-excreción de Toxocara canis reconocidos por cachorros del área metropolitana de la Ciudad de México / Secretory-excretory antigens of Toxocara canis recognized by puppies of the Mexico City metropolitan area

The aim of the study was to determine the Toxocara canis larvae secretory-excretory antigens (SETc-Ag), which are most often recognized by puppies infected naturally from the metropolitan area of Mexico City. At necropsy, adult phases of T. canis were found in the intestine of 20 puppies (64.6%), and 11 had no parasites (35.4%). Sera of all animals with T. canis in the intestine and seven animals without worms were positive to ELISA (X = 0.683 ± 0.184 OD) and recognized several SETc-Ag by Western blot (WB). Sera from four puppies with no T. canis did not recognize any type of antigen by WB and were negative to ELISA-IgG (X = 0.078 ± 0.045 OD). Sera from the puppies recognized three antigen groups. The first one included seven low molecular weight antigens (16, 20, 23, 24, 28, 32 and 38 kDa); the second one, three high molecular weight antigens (400, 200 and 120 kDa) and the third one, four antigens of intermediate molecular weight (86, 74, 66 and 47 kDa). The most frequently recognized SETc-Ag were of 32, 38, 66, 120 and 200 kDa, which makes them good candidate antigens to develop immunodiagnosis tests in dogs.

El propósito del presente trabajo fue determinar los antígenos de secreción-excreción de larvas de Toxocara canis (Ag-SETc) que son más frecuentemente reconocidos por cachorros infectados naturalmente del área metropolitana de la Ciudad de México. A la necropsia, 20 cachorros presentaron fases adultas de T. canis en el intestino (64.6%) y 11 no presentaron (35.4%). El suero de todos los animales con T. canis en el intestino y de siete animales, sin gusanos a la necropsia, fueron positivos a ELISA (X = 0.683 ± 0.184 DO) y reconocieron, por Western blot (WB), varios Ag-SETc. El suero de cuatro cachorros sin T. canis en el intestino no reconoció ningún antígeno por WB y fueron negativos a ELISA-IgG (X = 0.078 ± 0.045 DO). Los sueros de los cachorros reconocieron tres grupos de antígenos. El primero incluyó siete de bajo peso molecular (16, 20, 23, 24, 28, 32 y 38 kDa); el segundo, tres de alto peso molecular (400, 200 y 120 kDa) y el tercero antígenos de peso molecular intermedio (86, 74, 66 y 47 kDa). Los Ag-SETc más frecuentemente reconocidos fueron de 32, 38, 66, 120 y 200 kDa, por lo que éstos son candidatos para pruebas de inmunodiagnóstico en perros.
