Ehrlichia chaffeensis is a bacterium belonging to the Anaplasmataceae family. In Mexico, only 2 species have been recorded in association with tick species and humans. The objective of the present study was to detect the presence of bacteria of the genus Ehrlichia in ticks collected from the Chamela-Cuixmala Biosphere Reserve, Jalisco, Mexico. The collected ticks were identified and analyzed individually by polymerase chain reaction to amplify a fragment of the Anaplasmataceae 16S rRNA gene and the Ehrlichia-specific dsb gene...

BACKGROUND: Uterine didelphys (UD) develops from failure of fusion of the paired Müllerian ducts, resulting in two noncommunicating uteri. We present a 31-year-old pregnant woman whose UD anomaly had not been detected during two previous cesarean sections and her presentation to a health-care clinic for her fifth pregnancy. CASE PRESENTATION: She was referred to our obstetrics clinic due to suspicion of abdominal pregnancy and a complaint of severe lower abdominal pain...

BACKGROUND: There is wide variation in the language used to describe Mullerian structures. To standardize terminology, the American Society of Reproductive Medicine (ASRM) created the Mullerian Anomalies Classification (MAC) in 2021. The objective of this study was to evaluate the applicability of the MAC nomenclature to pediatric patients with cloaca. METHODS: A retrospective review of all patients with cloaca was performed at a single institution. Descriptions of Mullerian structures were evaluated and compared to the ASRM MAC categories...

Didelphis albiventris is considered the most common marsupial in Rio Grande do Sul. With omnivorous and synanthropic habits, it can serve as a host to various parasites, playing an important role in maintaining their biological cycle. Despite being a widespread and abundant species, it has a relatively little-known parasitic fauna. Therefore, the aim of this study was to report the diversity of parasites in a fecal sample from D. albiventris in Rio Grande do Sul, Southern Brazil. Modified Centrifugal-flotation and Spontaneous sedimentation techniques were used, revealing a high taxonomic diversity of parasites...

BACKGROUND: Congenital uterine anomalies (CUA) can be associated with impairments of early and late pregnancy events. OBJECTIVE: To assess the impact of CUA on reproductive outcomes in pregnancies conceived spontaneously or after assisted reproduction. MATERIALS AND METHODS: Systematic review and meta-analysis of cohort studies comparing patients with CUA versus women with normal uterus. A structured literature search was performed in leading scientific databases to identify prospective and retrospective studies...

We record and analyze the movement patterns of the marsupial Didelphis aurita at different temporal scales. Animals trajectories are collected at a daily scale by using spool-and-line techniques and, with the help of radio-tracking devices, animals traveled distances are estimated at intervals of weeks. Small-scale movements are well described by truncated Lévy flight, while large-scale movements produce a distribution of distances which is compatible with a Brownian motion. A model of the movement behavior of these animals, based on a truncated Lévy flight calibrated on the small scale data, converges towards a Brownian behavior after a short time interval of the order of 1 week...

INTRODUCTION AND IMPORTANCE: Longitudinal vaginal septum is usually associated with uterine anomalies, such as septate uterus and didelphys uterus. Normal uterus and cervix found in longitudinal vaginal septum is a rare case but can affect sexual activities and reproductive outcomes. CASE PRESENTATION: We present a case of a 42-year-old woman with a history of primary infertility for 7 years was referred by the endocrinology division due to the presence of a longitudinal vaginal septum and difficulty in performing intrauterine insemination...

INTRODUCTION: Herlyn-Werner-Wunderlich syndrome is a rare complex congenital disorder, presenting with obstructed vagina, uterus didelphys and ipsilateral renal agenesis. Hemivaginal obstruction firstly asymptomatic, leads to symptoms after menarche such as dysmenorrhea, pelvic pain or infertility. CASE PRESENTATION: A 15-year-old patient presenting with few symptoms, transvaginal ultrasound reveals an hematocolpos, we report also typical findings of this disorder on magnetic resonance imaging...

The genus Dracunculus contains numerous species of subcutaneous parasites of mammals and reptiles. In North America, there are at least three mammal-infecting species of Dracunculus . Reports of Dracunculus infections have been reported from river otters ( Lontra canadensis ) since the early 1900s; however, little is known about the species infecting otters or their ecology. Most reports of Dracunculus do not have a definitive species identified because females, the most common sex found due to their larger size and location in the extremities of the host, lack distinguishing morphological characteristics, and few studies have used molecular methods to confirm identifications...

A review of an unusual twin type-twins born to women with two uteri (uterus didelphys)-is presented. This review is followed by summaries of recent research and perspectives concerning prenatal aneuploidy screening for twin pregnancies, twin conceptions by same-sex male couples, legal personality of conjoined twins, and a twin study of cannabis use. Interesting information about twins that has appeared in the media is also presented, namely how being taken for twins saved a pair of sisters; twin children of a jailed Nobel Prize winner, British 'biracial' twins, triplets born at the start of Russia's attack on Ukraine, and twins born in different years...

Bicornis unicollis uterus is a rare congenital uterine abnormality that occurs due to the failure of Mullerian duct fusion early in the development of the female internal genitalia system. In this case report, we present a woman with bicornis unicollis uterus who had preterm birth. A 30-year-old female patient with two caesarean sections history with premature babies was presented to the hospital with a complaint of regular contractions for twelve hours in her third preterm pregnancy. The patient has no particular symptoms besides acute abdominal pain...

Herlyn-Werner-Wunderlich syndrome (HWWS), also known as OHVIRA syndrome (obstructed hemivagina and ipsilateral renal anomaly) is a complex congenital malformation characterized by a triad including uterine didelphys, hemivaginal obstruction, and ipsilateral renal agenesis. In this case report, we present a case of HWWS along with the challenges in diagnosis and multi-step treatment processes. A 25-year-old woman presented to Dr. Zainoel Abidin Hospital in Banda Aceh, Indonesia with a chief complaint of lower back pain for the past six months (two months after the marriage)...

Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome, a rare genetic condition of the urogenital system, is characterized by distinctive features such as ipsilateral renal agenesis, obstructed hemivagina, and uterus didelphys. It is also referred to as Herlyn-Werner-Wunderlich (HWW) syndrome. Its clinical manifestations include dysmenorrhea, consistent abdominal pain, and infrequent periods. It is typically diagnosed after menarche. We report a case of a 20-year-old female who was admitted to the casualty ward following a road accident...

The Herlyn-Werner-Wunderlich syndrome (HWWS) is a very rare congenital anomaly of the urogenital tract. It is characterized by a combination of didelphys uterus, unilateral vaginal obstruction, and ipsilateral renal agenesis. MRI imaging is usually used for diagnosis; however, the authors present a case of HWWS diagnosed by ultrasonography (HSG) and hysterosalpingography (HSG) in a 22-year-old lady who has undergone an imaging workup of infertility.

Crocodilians are considered to be "ecosystem engineers" because their modification of habitats provides opportunities for feeding, drinking, breeding, and other vital life activities to a wide variety of other animals. One such habitat modification is the construction of nest mounds during the breeding season by most crocodilian species, including American alligators ( Alligator mississippiensis ). While many reports exist describing wildlife associated with alligator nests, no studies have quantified faunal associates and their corresponding behaviors while visiting nests...

BACKGROUND: Chagas disease, affecting approximately eight million individuals in tropical regions, is primarily transmitted by vectors. Rhodnius prolixus, a triatomine vector, commonly inhabits in ecotopes with diverse palm tree species, creating optimal conditions for vector proliferation. This study aims to explore the transmission ecology of Trypanosoma cruzi, the causative parasite of Chagas disease, by investigating the feeding patterns and natural infection rates of R. prolixus specimens collected from various wild palm species in the Colombian Orinoco region...

Angiostrongylus costaricensis is a metastrongyloid nematode that primarily infects the mesenteric arteries of wild rodents. This parasite is endemic in several regions of the American continent, and in humans, causes a disease known as abdominal angiostrongyliasis. Despite the important health implications of this nematode, there are limited studies investigating the involvement of wild animals in its life cycle. In this study, we present the clinical manifestations, pathologic findings, and molecular diagnosis, to the best of our current knowledge, of the first documented onset of cerebral angiostrongyliasis because of A...

Ticks are hematophagous arthropods and, during feeding, may transmit pathogens to vertebrate hosts, including humans. This study aimed to investigate the presence of Rickettsia spp. in ticks collected between 2010 and 2013 from free-ranging capybaras (Hydrochoerus hydrochaeris) and opossums (Didelphis albiventris) that inhabit Sabiá Park in Uberlândia, Brazil. Overall, 1,860 ticks were collected: 1,272 (68.4%) from capybaras (487 of the species Amblyomma sculptum, 475 adults and 12 nymphs; 778 Amblyomma dubitatum, 727 adults and 51 nymphs; and seven larva clusters of the genus Amblyomma); and 588 (31...
