En una madre competente en tйrminos inmunolуgicos, por lo general los estudios aceptan que el Toxoplasma se transmite al feto a partir de una infecciуn adquirida justo antes o durante el embarazo, es decir, antes del inicio de la fase latente de la infecciуn. Sin embargo, se han informado casos raros de infecciуn a travйs de la placenta en los cuales la madre habнa tenido una infecciуn anterior latente. El riesgo de la infecciуn transplacental aumenta con el embarazo, pero el riesgo de enfermedad grave o muerte del feto disminuye. Los sнntomas que normalmente se asocian con una infecciуn transplacental incluyen aborto espontaneo, muerte del feto, dilataciуn ventricular y calcificaciуn intracraneal (Guy, Dubey & Hill, 2012). Los fetos infectados en las ъltimas etapas del embarazo suelen ser asintomбticos o presentan solo complicaciones moderadas. Una vez mбs, hay variaciones dependiendo de la cepa de Toxoplasma, donde los sнntomas mбs graves aparentemente estбn asociados con la toxoplasmosis congйnita en Amйrica del Sur (Gуmez-Marin et al. Importancia para el comercio e impacto en las poblaciones econуmicamente vulnerables Puesto que la distribuciуn de la toxoplasmosis es mundial, la importancia para el comercio generalmente se considera mнnima. Sin embargo, la importaciуn y exportaciуn de carne helada (no congelada), incluido vacuno y equino, pueden permitir la propagaciуn de los diferentes genotipos de Toxoplasma, donde una preocupaciуn especнfica es la importaciуn de cepas mбs virulentas en zonas nuevas (Pomares et al. Por lo tanto, la principal preocupaciуn parece ser que las poblaciones vulnerables a la toxoplasmosis clнnica estбn aumentando, mientras que las cepas mбs virulentas tienen la posibilidad de extenderse con el comercio de frutas, verduras, carne y animales.

Genetic analyses of atypical Toxoplasma gondii strains reveal a fourth clonal lineage in North America. El ciclo silvestre estб generalizado en todos los continentes, de zonas glaciales a tуrridas, salvo en la Antбrtica, y se mantiene por las conductas canнbales y carroсeras de animales carnнvoros y omnнvoros. Solo los humanos presentan la enfermedad clнnica, triquinelosis, mientras que los animales son por lo general asintomбticos y solo aquellos infectados experimentalmente con una enorme cantidad de larvas pueden desarrollar los sнntomas de la enfermedad. Los humanos adquieren la infecciуn con la ingesta de carne cruda o poco cocida de cerdos domйsticos y salvajes, osos, morsas, caballos, tejones, perros, pumas, chacales y tortugas. La carne y los derivados de todos los animales sensibles a la Trichinella constituye un riesgo para los humanos si se consume cruda o semi-cruda (Pozio and Murrell, 2006). Distribuciуn geogrбfica Los parбsitos de la Trichinella tienen una distribuciуn mundial, salvo en la Antбrtica, con prevalencias variables segъn las condiciones ambientales (temperatura baja y humedad alta versos temperatura alta y humedad baja), la vida silvestre y la conducta humana. Por ejemplo, el hбbito comъn de los cazadores de dejar el cadбver del animal tirado en el campo luego de sacarle la piel o retirar y descartar las entraсas aumenta la probabilidad de transmitir el parбsito a nuevos hospederos (Pozio & Murrell, 2006). En 1998, se estimу que la prevalencia mundial de la triquinelosis era de alrededor de 11 millones (Dupouy-Camet, 2000). Esta estimaciуn se basу en el supuesto de que la cantidad de casos de triquinelosis era similar al nъmero de personas afectadas por la teniasis/cisticercosis, puesto que ambas enfermedades se transmiten con el consumo de carne de cerdo. Esta cifra se calculу sumando la tasa de incidencia mбs alta informada en todos los paнses durante un perнodo de 10 aсos (Pozio, 2007). Esta revisiуn de la bibliografнa disponible en todo el mundo desde 1986 hasta 2009 encontrу informes de 65. La mayor parte de las infecciones (87%) ha sido documentada en Europa, y la mitad de ellas solo en Rumania. Enfermedad Severidad de la morbilidad aguda En la mayorнa de las personas, el inicio de la etapa grave es repentina e incluye debilidad general, escalofrнos, dolor de cabeza, fiebre (hasta de 40°C), sudoraciуn excesiva y taquicardia. En casi todos los casos, se producen edemas simйtricos en pбrpados y perioculares y es frecuente que el edema afecte toda la cara. Los vasos sanguнneos de la conjuntiva se inflaman y en algunas personas, se producen petequias, hemorragias intraconjuntivales y hemorragias del lecho ungueal. Esta sintomatologнa viene seguida de dolor en diversos grupos musculares, lo que puede restringir la movilidad. El dolor se desarrolla en los mъsculos de la nuca y el tronco, en los mъsculos de las extremidades inferiores y superiores y, con menos frecuencia, en los mъsculos maseteros.

In such conditions, human infection caused by simian plasmodia may occur naturally. In western Malaysia, a similar situation exists: the vector is the same for the human and nonhuman cycles, and zoonotic infections may thus occur. However, the risk appears to be limited to those who live in or enter jungle areas, and it is unlikely that the infection could spread to other human communities. However, malariologists point out that the plasmodia of nonhuman primates pose little risk for the human population, since P. Diagnosis: Routine diagnosis in man and in monkeys is done by examining the parasite in thick blood films stained with Giemsa stain. Another difficulty in diagnosis by microscopic examination of blood preparations is the low parasitemia that occurs in nonhuman primates. To get around this difficulty, inoculation of blood into susceptible monkeys is recommended. Although serologic reactions are useful as a means of confirming malarial infection, they are rarely specific enough to identify the Plasmodium species involved. Control: Malaria experts agree that malaria of nonhuman primates does not constitute an obstacle for programs to control and eradicate human malaria. The human infection has been eradicated from some parts of Brazil, although high rates of infection in monkeys persist. Given the small number of confirmed cases of human infection by plasmodia of simian origin and the benign nature of the clinical manifestations, special control measures are not justified. To prevent the disease, nonimmune persons who must go into the jungle should use insect repellents on exposed body parts and on clothing. Regular use of chemoprophylaxis would be justified only if the nonimmune person had to live in an area where human malaria is endemic.

Although there are some 700 species that infect vertebrates and invertebrates, the species identified to date as parasites of man are Enterocytozoon bieneusi, Encephalitozoon intestinalis (formerly Septata intestinalis), Encephalitozoon hellem, Encephalitozoon cuniculi, and some species of the genera Nosema, Pleistophora, Trachipleistophora, and Vittaforma (Scaglia et al. Enterocytozoon causes intestinal infections almost exclusively, while Encephalitozoon may cause intestinal or systemic infections which may spread to various organs. Parasites of the genera Nosema, Pleistophora, Trachipleistophora, and Vittaforma are uncommon in man and do not affect the intestine (Field et al. Proof of the existence of isolates with genetic differences exists, at least within E. The genera Cryptosporidium, Isospora, and Cyclospora belong to a completely different phylum: Apicomplexa (formerly Esporozoa). Microsporidia are small intracellular protozoa that undergo a phase of asexual multiplication-merogony-followed by a phase of sexual multiplication-sporogony- during which they produce spores, or oocysts, inside the infected cell. The spores are released from the host cell and are eliminated into the external environment, where they may infect other individuals.

In addition, data from term birth as well as giving birth to infants who are small for gestational age. Immunization of people who are in close contact with children with high-risk conditions or with any child younger than 60 months (5 years) is an important means of protection for these children. Special effort should be made to vaccinate all women who are breastfeeding Timing of Vaccine Administration. The recommended vaccine dose and schedule for during the year after immunization and because in most years, at least one of the vaccine antigens is changed to match ongoing antigenic changes in circulating strains. More conservative approaches in children with a history of egg allergy, such as skin testing or a 2-step graded challenge, no longer are recommended. As a precaution, clinicians should determine whether the presumed egg allergy is based on a mild (ie, hives alone) or severe reaction (ie, anaphylaxis involving cardiovascular use of epinephrine). Pediatricians should consult with an allergist for children with a history of severe reaction. Most vaccine administration to people with egg allergy can happen without the need for referral. Data indicate that approximately 1% of children have immunoglobulin E (IgE)-mediated sensitivity to egg, and of those, a rare minority has a severe allergy. Standard immunization practice should include the ability to respond to acute hyperAppropriate resuscitative equipment must be readily available. Fever may occur within 24 hours after immunization in approximately 10% to 35% of children younger than 2 years but rarely in older children and adults. The most common systemic adverse events are drowsiness, irritability, loss of appetite, fatigue, muscle aches, headache, arthralgia, and gastrointestinal tract symptoms. These events are reported with comparable frequency among participants receiving the licensed comparator trivalent vaccines. The most commonly reported reactions in children are runny nose or nasal congestion, headache, decreased activity or lethargy, and sore throat. Antiviral medications currently licensed are impormivir currently are recommended. However, recommendations for use of these drugs for chemoprophylaxis may vary by location and season, depending on susceptibility patterns. For current recommendations about chemoprohtm or Indications for Chemoprophylaxis. Isosporiasis (now designated as Cystoisosporiasis) toisosporiasis, and can be profuse and protracted, even in immunocompetent people. Manifestations are similar to those caused by other enteric protozoa (eg, Cryptosporidium and Cyclospora species) and can include abdominal pain, cramping, anorexia, nausea, vomiting, weight loss, and low-grade fever. Humans are the only known host for C belli and shed noninfective oocysts in feces. These oocysts must mature (sporulate) outside the host in the environment to become infective. Under favorable conditions, sporulation can be completed in 1 to 2 days and perhaps more quickly in some settings. Oocysts probably are resistant to most disinfectants and can remain viable for prolonged periods in a cool, moist environment. The incubation period is uncertain but has ranged from 7 to 12 days in reported cases associated with accidental laboratory exposures. Pyrimethamine (plus leucovorin, to prevent myelosuppression) is an alternative treatment for people who cannot tolerate trimethoprimNitazoxanide also has been reported to be effective, but data are limited. In adolescents and adults, maintenance therapy is recommended to prevent recurrent disease for people 3. If untreated, approximately 20% of children will develop coronary artery abnormalities, including aneurysms. The illness is characterized by fever and the following clinical features: (1) bilateral bulbar conjunctival injection with limbic sparing and without exudate; (2) erythematous mouth and pharynx, strawberry tongue, and red, cracked lips; (3) a polymorphous, generalized, erythematous rash that can be morbilliform, maculopapular, or scarlatiniform or may resemble erythema multiforme; (4) changes in the peripheral extremities consisting of induration of the hands and feet with erythematous palms and soles, often with later periungual desquamation; and (5) acute, nonsuppurative, usually unilateral, cervical lymphdelayed in patients who come to attention because of fever and unilateral cervical lymphadenitis, which mistakenly is thought to be bacterial lymphadenitis; a distinguishing feaings. The presence of a concurrent or preceding viral upper respiratory infection does not cal criteria in the presence of fever and coronary artery abnormalities.
