Odontogenesis is guided by a complex signaling cascade in which several molecules, including FGF2-4, ensure all dental groups development and specificity. Most of the data on odontogenesis derives from rodents, which does not have all dental groups. Didelphis albiventris is an opossum with the closest dentition to humans, and the main odontogenesis stages occur when the newborns are in the pouch. In this study, D. albiventris postnatals were used to characterize the main stages of their molars development; and also to establish FGF2, FGF3 and FGF4 expression pattern...

The patient was a 32-year-old woman who presented with infertility secondary to uterine didelphys. Hysteroscopic metroplasty was chosen as the corrective surgical procedure for this anatomical defect. During the surgical repair, the patient developed a massive air embolism (MAE) leading to hypotension, arrhythmia, and cardiogenic shock. Resuscitation was started by placing the patient in the right-side up position, and emplacement of central venous catheter, but it was unsuccessful. The decision was then made to bypass the patient's cardiopulmonary system to effectively treat the MAE...

Direct and indirect contacts among individuals drive transmission of infectious disease. When multiple interacting species are susceptible to the same pathogen, risk assessment must include all potential host species. Bovine tuberculosis (bTB) is an example of a disease that can be transmitted among several wildlife species and to cattle, although the potential role of several wildlife species in spillback to cattle remains unclear. To better understand the complex network of contacts and factors driving disease transmission, we fitted proximity logger collars to beef and dairy cattle (n=37), white-tailed deer (Odocoileus virginianus; n=29), raccoon (Procyon lotor; n=53), and Virginia opossum (Didelphis virginiana; n=79) for 16 months in Michigan's Lower Peninsula, USA...

BACKGROUND: The classical theory of Müllerian origin of upper vagina fails to explain complex urogenital malformations like OHVIRA syndrome; the Acien's hypothesis, however, unravels the hidden embryopathogenesis. As per Acien, Wolffian (mesonephric) ducts instead of Müllerian ducts and sinovaginal bulbs, give rise to the vagina. The new hypothesis, however, retains the concept of origin of the ureters (with ureters inducing renal development) by the former and the uterus by Müllerian ducts...

The infection by S. falcatula is commonly associated with respiratory disease in captive psittacine birds, with a few case reports of this protozoan causing encephalitis in wild birds. We describe the clinical, pathological, and molecular aspects of an infection by S. falcatula in a bare-faced ibis (Phimosus infuscatus). Clinically, wing paralysis and mild motor incoordination were observed. At necropsy, the telencephalic cortex showed multifocal to coalescing yellowish soft areas. Histologically, multifocal to coalescent nonsuppurative necrotizing meningoencephalitis of telencephalic cortex, cerebellum, and brainstem was observed...

INTRODUCTION: Road-killed wild animals host zoonotic pathogens such as Toxoplasma gondii, offering a new opportunity for the epidemiological study of these infectious organisms. METHODS: This investigation aimed to determine the presence of T. gondii and other apicomplexan parasites in tissue samples of 64 road-killed wild animals, using polymerase chain reaction (PCR). Positive samples were then typed by PCR-restriction fragment length polymorphism (RFLP) using 7 markers: SAG1, 5'-3'SAG2, SAG3, BTUB, c29-6, PK1, and Apico...

Nematode parasites of the cardiopulmonary system of livestock and pet animals have been receiving attention due to the pathogenic effects they produce in the course of the infection. However, parasitism in wild animals by metastrongilid nematodes has been neglected, resulting in potential risk to wildlife. Heterostrongylus heterostrongylus is the etiological agent of bronchial pneumonia in the black-eared opossum, Didelphis aurita, a widely distributed marsupial frequently reported to inhabit areas from wild environments to peri-urban spaces...

The synanthropic behavior of marsupials of the genus Didelphis in endemic areas of leishmaniasis suggests that these animals may play an important role in the epidemiology of this infection. The aim of the present study was to detect Leishmania spp. DNA in Didelphis albiventris (white-eared opossum) and Didelphis aurita (big-eared opossum) living in forested and peridomestic areas of northeastern Brazil. Blood samples were collected from 25 animals (23 D. albiventris and 2 D. aurita ) by cardiac puncture and then analyzed via PCR...

OBJECTIVE: Müllerian anomalies are associated with increased risk of miscarriage, intrauterine growth restriction (IUGR) and preterm birth. While a commonly implicated cause is restricted expansion of endometrial cavity, alternatively it could be due to abnormal placentation. We sought to examine clinical and histopathologic factors associated with preterm delivery in women with Müllerian anomalies. STUDY DESIGN: One hundred and eleven singleton pregnancies in 85 women were analyzed retrospectively...

There is a growing concern about the participation of wild hosts and reservoirs in the epidemiology of leishmaniasis, particularly within the context of increasingly frequent environmental changes and the expansion of the One Health concept. This work is a molecular research of infection by Leishmania spp. among the wildlife of an environmentally protected area located in the municipality of Campinas, São Paulo, Brazil. The studied area has a history of intense environmental changes, with notifications of human cases of cutaneous leishmaniasis in the 1990s, and a focus of canine visceral leishmaniasis since 2009...

Bobcats (Lynx rufus) are wide-ranging mammals found throughout the continental USA. As carnivores near the top of their food chain, bobcats would seem to be a useful bioindicator of metal pollution in terrestrial environments. However, there is very limited research on bobcats in toxicology studies. Here, we offer the first analysis of metal (copper, selenium, silver, and zinc) contaminants in the livers of wild bobcats. Liver tissues from 120 adult bobcats (i.e., estimated to be ≥1 year old) were collected from 2003 to 2006 at four sites in Georgia and Florida, USA that experienced relatively similar levels of human disturbance...

Due to a resurgence of flea-borne rickettsioses in Orange County, California, we investigated the etiologies of rickettsial infections of Ctenocephalides felis, the predominant fleas species obtained from opossums (Didelphis virginiana) and domestic cats (Felis catus), collected from case exposure sites and other areas in Orange County. In addition, we assessed the prevalence of IgG antibodies against spotted fever group (SFGR) and typhus group (TGR) rickettsiae in opossum sera. Of the 597 flea specimens collected from opossums and cats, 37...

BACKGROUND: In a uterine didelphys with two cervices, cervical screening may not reveal the same abnormalities. CASE: We present a patient with a uterine didelphys with two cervices in a single vagina after resection of a longitudinal vaginal septum at age 12. She presented with abnormal Pap test results with the right and left cervices discordant from each other. Despite both cervices sharing stroma in the midline, her right cervix was negative for human papillomavirus (HPV) and dysplasia, while her left cervix was HPV positive with high-grade cervical dysplasia on an excisional specimen...

BACKGROUND: Herlyn-Werner-Wunderlich Syndrome (HWWS) is a rare Müllerian anomaly characterized by uterus didelphys coexisting with an obstructed hemivagina and ipsilateral renal agenesis. CASE: A 13-year-old female presented one-year after menarche with severe dysmenorrhea and a right-sided pelvic mass. Imaging identified a right uterus with hematometra, hematocolpos, absent right kidney, normal left kidney, ureter, left uterus, and vagina compressed to the left by right hematocolpos...

The Virginia opossum (Didelphis virginiana) is a highly active scavenger whose behavior has significant impacts on rates of decomposition and skeletonization, which have previously not been addressed. In this study, scavenging by the opossum led to the skeletonization of carcasses in half of the accumulated degree days (ADD) of a comparable non-scavenged control carcass. Opossums used body orifices, as well as natural tears caused by the decomposition process, to access internal tissues and consume them. This activity resulted in little movement of the carcass and the retained appearance of natural undisturbed decomposition...

BACKGROUND: Müllerian tract anomalies have been reported in 2-3% of females. Uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis (OHVIRA) syndrome is a rare condition, with only a few cases of the syndrome occurring during pregnancy having been reported. CASE: A 35-year-old, nulli-gravid woman at 18 weeks of gestation was referred due to cervical incompetence. Her first symptom was genital bleeding. Ultrasonography and MRI led to the diagnosis of OHVIRA syndrome, and pregnancy was confirmed on the affected side with the amniotic sac found to be protruding from the cervix into the vaginal cavity...

We present a 33-year-old woman with an array of congenital abnormalities. She has been diagnosed with polycystic kidney disease (PCKD) with no detectable mutations in PKD1 or PKD2, spina bifida occulta, thoracic skeletal abnormalities, a uterus didelphys and a patent foramen ovale (PFO). There are several associations reported in the literature that include abnormalities similar to the patient's, but none describe her presentation in its entirety. The MURCS association is characterised by (MU)llerian duct aplasia, (R)enal dysplasia and (C)ervical (S)omite anomalies and goes some way in explaining these condition...
