Con el fin de dar un aprovechamiento a los lodos cloacales en Costa Rica y realizar primer co-compostaje su clase país, se realizó ensayo por 150 días la provincia Heredia. Objetivo: Comparar tratamiento una mezcla con dos tipos estructurantes, sin pulpa café, evaluando las diferencias proceso calidad del producto final. Metodología: Los tratamientos pilas aireadas aeróbicas consistieron tres t...

Currarino syndrome is a rare congenital malformation characterised by the triad of: an anorectal malformation, sacral bony defect and presacral mass. One but possible anal canal duplication, anomaly which not only most distal also rarest form of digestive tract duplication. We present case four-year-old female who had complete including

Twenty populations of Radopholussimilis from three countries and different hosts (19 populations from ornamental plants and one population from ginger) were compared using morphological characters, morphometrics and karyotype between progeny from both single females and 30 females of each population. Morphological diversity existed in and among the populations, even within the progeny nematodes...

Costa Rica has a significant number of snakebites per year and bacterial infections are often complications in these animal bites. Hereby, this study aims to identify, characterize, and report the diversity of the bacterial community in the oral and cloacal cavities of venomous and nonvenomous snakes found in wildlife in Costa Rica. The snakes where captured by casual encounter search between A...

In mammalian embryos, male and female external genitalia develop from the genital tubercle. Outgrowth of the genital tubercle is maintained by the urethral epithelium, and it has been reported that Fgf8 mediates this activity. To test directly whether Fgf8 is required for external genital development, we conditionally removed Fgf8 from the cloacal/urethral epithelium. Surprisingly, Fgf8 is not ...

Beak and feather disease virus- (BFDV-) positive (naturally infected) but clinically healthy budgerigars (Melopsittacus undulatus) were inoculated with two isolates of Mycobacterium avium subsp. avium isolated from naturally infected golden pheasant (Chrysolophus pictus) and peafowl (Pavo cristatus). During a period of more than two months after inoculation, samples of cloacal and crop swabs, f...

The effects of events which occur prior to slaughter, such as loading, transport, and holding at an abattoir, on the prevalence of Campylobacter species, including Campylobacter jejuni and Campylobacter coli, were examined. Cloacal swabs from market-weight turkeys in each of five flocks were obtained on a farm prior to loading (time 1; 120 swabs per flock) and after transport and holding at the...

This study presents an interconnected approach for circumventing two inherent limitations associated with studies defining the natural history of influenza A viruses in wild birds. The first limiting factor is the ability to maintain a cold chain from specimen collection to the laboratory when study sites are in more remote locations. The second limiting factor is the ability to identify all in...

This paper represents the first ultrastructural descriptions of the cloacal glands of a male salamander. All male salamanders in the suborder Salamandroidea possess these glands, which are required for internal fertilization. These glands are responsible for producing spermatophores and, in some species, certain glands produce female-attracting pheromones. Both scanning and transmission electro...
