Prevalence and Progression of Gingivitis in Domestic Cats in Subtropical Mexico.

With the objective to characterize the gingival index (GI) and its progression, 218 domestic cats in a subtropical region of Mexico were studied. All teeth of each cat were examined with a periodontal probe to determine the GI; in addition, the absence of teeth was recorded. Six months later, the teeth of the 38 cats were again examined to assess any progression of the GI and loss of teeth.

Anatomical landmarks for a proximal paravertebral thoracolumbar block in sheep: Cadaver and study.

The objective of this study was to describe the anatomy of the spinal nerves, specifically the last thoracic nerve (T13) and the first to third lumbar nerves (L1 to L3), in order to safely carry out an accurate proximal paravertebral block (PPVB) in sheep. This study consisted of 2 phases. In Phase 1, 7 sheep cadavers were dissected to identify the path and relevant anatomical landmarks of spinal nerves T13 and L1 to L3.

Evaluation of the effectiveness of fluralaner against adult stages of Rhodnius prolixus in dogs.

Triatomines are vectors of American Trypanosomiasis also known as Chagas´ disease where several reservoirs including dogs are involved in the transmission cycle of the causal agent (Trypanosoma cruzi). Considering that the prevalence of American trypanosomiasis in dogs is higher than in humans and that dogs in addition are susceptible of this disease, and are involved in peridomestic transmission to humans, the search for new alternatives for vector control of the triatomines responsible for transmission in dogs is required. Over the 20 weeks the study lasted, 600 individual female, adult of Rhodnius prolixus were offered to the 15 dogs treated with a single oral dose of Fluralaner (Bravecto®, MSD).

Comparison of Propofol or Isoflurane Anesthesia Maintenance, Combined with a Fentanyl-Lidocaine-Ketamine Constant-Rate Infusion in Goats Undergoing Abomasotomy.

This study aimed to compare, first, the anesthetic and cardiopulmonary effects of propofol or isoflurane anesthetic maintenance in goats receiving a fentanyl-lidocaine-ketamine infusion undergoing abomasotomy and, secondly, to compare the quality of the recovery from anesthesia. Two groups were used: propofol (TIVA) and isoflurane (PIVA). Goats were premedicated with fentanyl (10 μg/kg intravenously [IV]), lidocaine (2 mg/kg, IV), and ketamine (1.

Presence of congenital anomalies in three dog litters.

This report describes multiple congenital malformations found in three dog litters delivered by emergency caesarean section. In all of the litters, some puppies were born alive but were euthanized because of the seriousness of their malformations and low probability of survival. In two litters, gastroschisis was associated with amelia of the right anterior limb.

A fatal case of canine cutaneous leishmaniosis in a dog.

A 10-year-old intact female Chihuahua, 2.5 kg of weight and BCS 2 (range 1–5) was taken in for medical consultation due to the presence of four skin lesion, two in the ventral thoracic region and two in the dorsal region. The dog was receiving medication due to congestive heart failure.

in Captive Wild Felids of Mexico: Its Frequency and Capability to Eliminate Oocysts.

There is little information about in wild felids, even when these species have been associated with cases of toxoplasmosis in humans. In this study, samples of serum and whole blood were collected from 42 felids from 10 different species, in 4 Mexican zoos. Stool samples from 36 animals were also collected, corresponding to 82% of the felids included in the study.

Stray Dog Population in a City of Southern Mexico and Its Impact on the Contamination of Public Areas.

To assess the risk of zoonotic pathogen transmission as function of stray dog presence and health status, a cross-sectional study was carried out in a large city of southern Mexico that lacks comprehensive strategies for the control of stray canine populations. The photographic capture-recapture method was used to estimate the density of dogs/km. In the same way, dog feces from 14 public parks of the city were collected to determine the prevalence and intensity of infection with gastrointestinal parasites.

Quantitative and histological assessment of maternal-fetal transmission of Trypanosoma cruzi in guinea pigs: An experimental model of congenital Chagas disease.

Objective: We evaluated the effect of Trypanosoma cruzi infection on fertility, gestation outcome, and maternal-fetal transmission in guinea pigs (Cavia porcellus).

Methods: Animals were infected with T. cruzi H4 strain (TcI lineage) before gestation (IBG) or during gestation (IDG).

Prevalence of gastrointestinal nematode infections in goat flocks on semi-arid rangelands of northeastern Mexico.

The objective of this study was to determine the prevalence of gastrointestinal nematode (GIN) infection in goat flocks on semi-arid rangelands of northeastern Mexico (25° N, 350-400 mm annual precipitation). The study included 668 pluriparous goats from 18 herds in five municipalities of Coahuila and Nuevo Leon, Mexico. Five genetic groups were considered (predominance of Boer, Nubian, Alpine, Saanen, and Toggenburg).

Associated Factors to Seroprevalence of spp. in Dogs of Quintana Roo, Mexico.

The objective of this study was to determine the seroprevalence to spp. in dogs from Xcalak, Quintana Roo, Mexico, and the associated factors. Serum samples were obtained from 118 dogs and used in an indirect immunofluorescent assay test for the detection of antibodies against spp.

Parasitic Zoonoses in Humans and Their Dogs from a Rural Community of Tropical Mexico.

A cross-sectional study was made on 89 inhabitants and their dogs from a rural community of Yucatan, Mexico, to determine the serological prevalence of some zoonotic parasitic agents. Samples were taken to monitor the presence and intensity of infection with gastrointestinal parasites in dogs. In humans, the serological prevalence of T.

Lidocaine, dexmedetomidine and their combination reduce isoflurane minimum alveolar concentration in dogs.

The effects of intravenous (i.v.) lidocaine, dexmedetomidine and their combination delivered as a bolus followed by a constant rate infusion (CRI) on the minimum alveolar concentration of isoflurane (MACISO) in dogs were evaluated.

Postoperative analgesic effects of either a constant rate infusion of fentanyl, lidocaine, ketamine, dexmedetomidine, or the combination lidocaine-ketamine-dexmedetomidine after ovariohysterectomy in dogs.

Objective: To evaluate the postoperative analgesic effects of a constant rate infusion (CRI) of either fentanyl (FENT), lidocaine (LIDO), ketamine (KET), dexmedetomidine (DEX), or the combination lidocaine-ketamine-dexmedetomidine (LKD) in dogs.

Study Design: Randomized, prospective, blinded, clinical study.

Effects of lidocaine, dexmedetomidine or their combination on the minimum alveolar concentration of sevoflurane in dogs.

The aim of this study was to determine the effects of lidocaine (LIDO) and dexmedetomidine (DEX) or their combination (LIDO-DEX), administered by constant-rate infusion (CRI), on the minimum alveolar concentration (MAC) of sevoflurane in dogs. Seven healthy mongrel dogs were used with a 2-week washout interval between treatments in this study. Anesthesia was induced with propofol and maintained with sevoflurane in oxygen, and MAC of sevoflurane was determined after 90 min equilibration period in the dogs (SEV-MACBASAL).

Study Design: Randomized, prospective, blinded, clinical study.

Animals: Fifty four dogs.

Common lesions in the female reproductive tract of dogs and cats.

Reproductive lesions are commonly seen in small animal practice. Lesions in the ovaries, uterus, and vagina may seriously influence normal reproductive capacity of dogs and cats and may put at risk the general health of the patients. The objective of this article is to give the veterinary practitioner a current and concise guide to the clinical signs, intraoperative changes, diagnosis, and treatment/management of lesions in the reproductive tract of the bitch and queen commonly seen in practice.

Effects of papaya seeds extract on the sperm characteristics of dogs.

The effect of chloroform extracts from seeds of the papaya plant (Carica papaya) on the spermatic characteristics of dogs was evaluated at doses of 50, 100 and 150 mg/kg, Groups 1, 2, and 3, respectively. Structural and ultrastructural changes in sperm cells and testicular parenchyma were also evaluated, and possible side effects were noted. Significant reductions in sperm concentration and motility were observed starting from Days 60 and 75, respectively, in all treated groups (P<0.
