Induction of estrus in suckled female yaks (Bos grunniens) and synchronization of ovulation in the non-sucklers for timed artificial insemination using progesterone treatments and Co-Synch regimens.

The objectives of the present study were to evaluate the induction of estrus and fertility in yak cows treated with Co-Synch regimens or progesterone (P(4)). In Experiment 1, postpartum suckled yaks were assigned to three treatments: (1) A (n=28), insertion of an intravaginal device containing P(4) (CIDR) on Day 0, PGF(2alpha) (i.m.) on Day 6 and PMSG (i.m.) at the time of CIDR removal on Day 7 (P(4)-PGF(2alpha)-PMSG); (2) B (n=21), PGF(2alpha) (i.m.) on Day 6 and PMSG on Day 7; (3) C (n=26), control group. Seven yak bulls were grazed with the cows for natural breeding. Rate of estrus within 9…

The Ultimate Buzzkill: When Dengue Hits Hard.

Dengue cases have been rising globally in recent years. In the United Arab Emirates (UAE) specifically, weather conditions have created an ideal breeding ground for the Aedes aegypti mosquito, the primary vector of the disease. We report the case of a 62-year-old South Asian male residing in the UAE who initially experienced vague flu-like symptoms. His condition progressively worsened, ultimately resulting in an unexpected out-of-hospital cardiac arrest and, tragically, death.

Anthropogenic effects on changing Q fever epidemiology in Russia.

In the northwestern region of Russia (Leningrad province) cattle is proved to be the main source of C. burnetii infection in humans, both in menaced professionals and in formally nonmenaced groups. Liquidation of specialized cattle-breeding complexes (with their well-organized veterinary surveillance) and broadening of the circle of non-professionals that contact with agriculture or domestic animals infected with C. burnetii provide the prerequisites to Q fever spreading among various groups of population.

Hereditary polydactyly in Simmental cattle.

Five breeding trials were conducted in an attempt to clarify the mode of inheritance of bovine polydactyly. Two trials involved polydactylous females, superovulation, embryo transfer, and early fetal recovery. The other three trials were father-daughter mating, mother-son mating, and polydactylous X polydactylous matings. The results suggest that the mode of inheritance of bovine polydactylism is polygenic, requiring a dominant gene at one locus and two recessive genes at another locus.

The Potential to Address Disease Vectors in Favelas in Brazil Using Sustainable Drainage Systems: Zika, Drainage and Greywater Management.

Residents of informal settlements, the world over, suffer consequences due to the lack of drainage and greywater management, impacting human … the mosquito in infecting residents. This inhibits recommendations made by professionals to reduce breeding opportunities for the disease vector. Whilst unrest is an issue in favelas, it is not the only issue preventing the human right to reliable, safe sanitation, including drainage. In "pacified" favelas which may be considered safe(r), the infrastructu …

PCR-RFLP molecular confirmation of color dilution alopecia in dogs in Brazil.

Color dilution alopecia (CDA) is a dermatopathy observed exclusively in animals having a diluted coat color. In dogs, color dilution occurs as a result of a single-nucleotide variation (SNV) c.-22G > A in the melanophilin gene. We standardized a PCR-restriction-fragment length polymorphism (PCR-RFLP) technique to identify this mutation and determine its frequency in dogs in Brazil. The standardized PCR-RFLP technique could efficiently identify the SNV c.-22G > A in the melanophilin gene, with mutated allele frequencies of 0.1, 0.1, and 0.0875 in Dachshund, Miniature Pinscher, and Yorkshire Ter

Serological study of brucellosis in Argentine Creole sheep.

Ovine cattle was introduced into America during the Spanish conquest with the second journey of Columbus to the Antilles and was disseminated throughout the region. In 1587, sheep were introduced into Argentina, later developing into the "Creole" breed. We selected 486 animals from different Argentine provinces with the aim of determining the serological status of brucellosis caused by Brucella melitensis and Brucella ovis. For the detection of antibodies against smooth Brucella spp., the Rose Bengal test (RBT) was performed as screening test while the serum agglutination test (SAT) and 2 merc

Causes of death and the impact of histiocytic sarcoma on the life expectancy of the Dutch population of Bernese mountain dogs and Flat-coated retrievers.

Bernese mountain dogs and Flat-coated retrievers are predisposed to hereditary oncological diseases. Since 1986 several authors have reported a high prevalence of tumours in both breeds, especially malignant histiocytosis/histiocytic sarcoma, which has a negative influence on life expectancy. However, many earlier reports included relatively low numbers of dogs, distributed over a small number of broad categories, often using outdated disease criteria. The aim of this study was to provide new data on causes of death, and the relative role of tumours, especially histiocytic sarcoma, collected a

Occurrence of Hepatozoon sp. in dogs in the urban area originating from a municipality in southeastern Brazil.

The occurrence of Hepatozoon sp. infection in dogs was evaluated in the urban area of Uberlândia, Minas Gerais, Brazil. The study involved 300 animals, 120 from the Veterinary Hospital of the Federal University of Uberlândia's Faculty of Veterinary Medicine, 80 from private clinics, and 100 from the Animal Protective Association (APA).
