To assess the risk of zoonotic pathogen transmission as function stray dog presence and health status, a cross-sectional study was carried out in large city southern Mexico that lacks comprehensive strategies for control canine populations. The photographic capture-recapture method used to estimate density dogs/km 2 . In same way, feces from 14 public parks were collected determine prevalence intensity infection with gastrointestinal parasites. population estimated between 65 80 thousand...
With the objective to evaluate prevalence of periodontal disease (PD) and monitor most affected teeth in dogs under subtropical conditions Mexico, 184 randomly selected underwent a examination. Of evaluated dogs, 78.8% showed some degree gingivitis them (76.6%) with moderate index, 30.4% presented PD being mild degree. Old age small size were more prone develop as reported elsewhere. Higher mobility index furcation seen maxillary 108 208 mandibular 308 408, but other involved less...
The effects of intravenous (IV) lidocaine, dexmedetomidine and their combination delivered as a bolus followed by constant rate infusion (CRI) on the minimum alveolar concentration isoflurane (MACISO) in dogs were evaluated. Seven healthy adult included. Anaesthesia was induced with propofol maintained isoflurane. For each dog, baseline MAC (MACISO/BASAL) determined after 90-minute equilibration period. Thereafter, dog received one following treatments (loading dose, CRI): lidocaine 2 mg...
The aim of this study was to determine the effects lidocaine (LIDO) and dexmedetomidine (DEX) or their combination (LIDO–DEX), administered by constant-rate infusion (CRI), on minimum alveolar concentration (MAC) sevoflurane in dogs. Seven healthy mongrel dogs were used with a 2-week washout interval between treatments study. Anesthesia induced propofol maintained oxygen, MAC determined after 90 min equilibration period (SEV-MACBASAL). Then, again 45 one following treatments: an intravenous...
The aim of this study was to determine the frequency and type renal lesions associated with positive titers against Leptospira sp. in a stray dog population. Three hundred fifty pairs kidneys an equal number serum samples were collected from dogs captured by pound Merida, Yucatan, Mexico. Euthanasia performed following regulations Official Mexican Health Ministry (NOM-033-ZOO-1995). Serum evaluated microscopic agglutination test, tissue processed fixed paraffin. After staining hematoxylin...
A cross-sectional study was made on 89 inhabitants and their dogs from a rural community of Yucatan, Mexico, to determine the serological prevalence some zoonotic parasitic agents. Samples were taken monitor presence intensity infection with gastrointestinal parasites in dogs. In humans, T. canis , gondii spiralis 29.2%, 91.0%, 6.7%, respectively. No associations found between positive cases studied variables. From total blood samples dogs, 87 (97.6%) seropositive ; only 52 viable fecal...
To characterize the clinical features of chronic kidney disease in dogs with serological evidence Leptospira spp. from an endemic region, thirty-three were clinically evaluated March 2019 to 2020, all also serologically tested for Ehrlichia canis and Anaplasma phagocytophilum . Seroprevalence was 39.4%. The most frequent serovars found Pyrogenes, Canicola, Bratislava Australis titters between 1:100 1:800. signs detected fever, depression, decreased body condition, vomiting, hematuria....
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. H4 strain (TcI lineage) before (IBG) or during (IDG). Tissue sera samples dams fetuses obtained near parturition. Results All IBG IDG seropositive by two tests, exhibited blood parasite load 1.62±2.2 50.1±62 parasites/μl, respectively, quantitative PCR. Histological evaluation showed muscle...
Contents A Burdizzo castrator was evaluated for the neutering of dogs. Histological and morphological changes spermatic cells peripheral serum testosterone after challenge with a GnRH‐analogue (gonadorelin) were assessed. There control group (G1), surgically castrated (G2) (G3) divided in two, G3a receiving two crunches each cord G3b one crunch cord. Sixteen days application blood samples taken from dogs at 30 min interval during 2 h; second sample treated 1 μ g/kg body weight gonadorelin...
Introducción. El tumor venéreo transmisible (TVT) es una neoplasia específica del perro que ocurre generalmente en la mucosa de los genitales. Éste transmitido principalmente durante el coito y se encuentra ampliamente distribuido ámbito mundial, donde perros callejeros tienen un papel importante diseminación. objetivo este trabajo fue determinar prevalencia TVT capturados concentrados perrera municipal ciudad Mérida Yucatán, México su frecuencia acuerdo al sexo edad animales. Materiales...
There is little information about Toxoplasma gondii in wild felids, even when these species have been associated with cases of toxoplasmosis humans. In this study, samples serum and whole blood were collected from 42 felids 10 different species, 4 Mexican zoos. Stool 36 animals also collected, corresponding to 82% the included study. used for search oocysts by light field microscopy PCR. Serum analyzed indirect immunoglobulin G (IgG) enzyme-linked immunosorbent assay (ELISA) fluorescent...
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 euthanized because seriousness their and low probability survival. two gastroschisis was associated with amelia right anterior limb. Other such as anencephaly also among different litters. morphological findings affected puppies, discusses most appropriate terminologies for each case highlights importance an...
The objective of this study was to determine the seroprevalence Ehrlichia spp. in dogs from Xcalak, Quintana Roo, Mexico, and associated factors. Serum samples were obtained 118 used an indirect immunofluorescent assay test for detection antibodies against A questionnaire obtain information about possible variables with seroprevalence. These analyzed through Chi 2 logistic regression. Dog 64% (75/118). Fifty-two percent (61/118) had tick infestation which identified as Rhipicephalus...
The natural exposure of domestic cats to Leptospira spp. and some associated risk factors were studied in a large city from tropical Mexico. Two hundred sixty blood samples collected clinically healthy Merida Yucatan, Mexico, tested for 13 leptospira serovars by using the microscopic agglutination test (MAT). Forty-six (17.7%) serologically positive antigens seven serovars, particularly australis (54.3%), pyrogenes (15.3%), gryppotyphosa (13%) others. Titters recorded within 1:100 1:200. No...
