1/33. Molecular identification and epidemiological tracing of pasteurella multocida meningitis in a baby.We report a case of pasteurella multocida meningitis in a 1-month-old baby exposed to close contact with two dogs and a cat but without any known history of injury by these animals. 16S rRNA gene sequencing of the isolate from the baby allowed identification at the subspecies level and pointed to the cat as a possible source of infection. molecular typing of Pasteurella isolates from the animals, from the baby, and from unrelated animals clearly confirmed that the cat harbored the same P. multocida subsp. septica strain on its tonsils as the one isolated from the cerebrospinal fluid of the baby. This case stresses the necessity of informing susceptible hosts at risk of contracting zoonotic agents about some basic hygiene rules when keeping pets. In addition, this study illustrates the usefulness of molecular methods for identification and epidemiological tracing of Pasteurella isolates.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
2/33. Molecular phylogenetic evidence for noninvasive zoonotic transmission of staphylococcus intermedius from a canine pet to a human.rRNA-based molecular phylogenetic techniques were used to identify the bacterial species present in the ear fluid from a female patient with otitis externa. We report the identification of staphylococcus intermedius from the patient and a possible route of transmission. Analysis of 16S ribosomal dna restriction fragment length polymorphisms indicated that the dominant species present was S. intermedius. A pet dog owned by the patient also was tested and found to harbor S. intermedius. In humans, the disease is rare and considered a zoonosis. Previously, S. intermedius has been associated with dog bite wounds, catheter-related injuries, and surgery. This study represents the first reported case of a noninvasive infection with S. intermedius.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
3/33. Salmonella virchow infection in an infant transmitted by household dogs.A 4-month-old male infant manifested diarrhea and Salmonella Virchow was isolated from his stool. The pathogen was repeatedly isolated from the infant over one month despite three regimens of treatment with antibiotics, to which the isolate was sensitive. Three household dogs were kept in his home and S. Virchow was isolated from two of them. The infant was admitted to hospital and was treated with antibiotic, then the pathogen was finally eliminated. Antibiotic sensitivity pattern and PFGE pattern produced by restriction enzyme Xba I of the isolate from the infant was completely similar to those of the isolates from the dogs. The above findings indicated that the present S. Virchow infection in the infant was transmitted by the household dogs.- - - - - - - - - - ranking = 5keywords = infection (Clic here for more details about this article) |
4/33. Canine salmonellosis: A review and report of dog to child transmission of salmonella enteritidis.dogs have been shown to harbor 53 salmonellae serotypes. Multiple simultaneous infections with 2 to 4 serotypes have been observed. The prevalence of canine salmonellosis may be a high as 27 per cent. salmonella typhimurium and S. anatum are the most common etiologic agents. dogs commonly experience a sub-clinical course of salmonellosis. Some investigators state that the dog may serve as a source of human infections. A few reports in the literature have documented this fact. The transmissions of S. enteritidis from dog to child is described in this article.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
5/33. prevalence of American trypanosomiasis (chagas disease) among dogs in oklahoma.OBJECTIVE: To determine the prevalence of trypanosoma cruzi infection among dogs in oklahoma. DESIGN: Cross-sectional study. animals: 301 owned or impounded dogs related by ownership or general geographic location to 3 dogs determined to have trypanosomiasis. PROCEDURES: blood samples were obtained from dogs between November 1996 and September 1997. Infection status was determined by use of a radioimmunoprecipitation assay. Second blood samples were obtained from some of the seropositive dogs for study by hemoculture and polymerase chain reaction (PCR) assay. Sites where infected dogs were found were inspected for triatomine insects, and light traps were used for vector trapping. RESULTS: 11(3.6%) dogs were seropositive for T. cruzi infection. Ten of the 11 were owned rural hunting dogs. Protozoal organisms isolated from the blood of 1 seropositive dog were identified as T. cruzi by PCR testing. Only 1 adult triatoma sanguisuga was captured in a light trap at a site near infected dogs; this insect was not infected. CONCLUSIONS AND CLINICAL RELEVANCE: Our findings suggest that T. cruzi is enzootic in eastern oklahoma. Measures that would reduce the risk of dogs acquiring T. cruzi infection are unlikely to be acceptable to their owners, and no effective drugs are available for treatment. The presence of T. cruzi-infected dogs poses a threat of transmission to persons at risk of exposure to contaminated blood veterinarians who practice in the southern united states should be cognizant of this blood borne zoonosis and educate all personnel about appropriate precautions.- - - - - - - - - - ranking = 3keywords = infection (Clic here for more details about this article) |
6/33. Neonatal sepsis by campylobacter jejuni: genetically proven transmission from a household puppy.We report a case of neonatal campylobacter jejuni sepsis in a 3-week-old infant who acquired the infection through transmission from a recently acquired household puppy. Genotyping of Campylobacter strains obtained from puppy and child resulted in highly homogeneous findings. This represents the first genetically proven C. jejuni dog-human transmission.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
7/33. Identification of isolates of streptococcus canis infecting humans.During a survey of Group G and C streptococcal infections of humans two epidemiologically unrelated Group G streptococcal isolates were identified, one from a case of bacteremia and one from a wound infection. These isolates were atypical among this sample in that the emm gene could not be amplified from them by PCR. Biochemical characterization identified the isolates as streptococcus canis, an organism normally associated with animal hosts. The biochemical identification was confirmed by sequencing of the 16S rRNA gene from both isolates and comparison with sequences of the S. canis type strain and other related streptococci of animals and humans. Comparative sequencing of fragments of two other housekeeping genes, sodA and mutS, confirmed that the isolates are most closely related to S. canis. The identification of two isolates of S. canis from a relatively small sample set suggests that the practice of identifying streptococci only by the Lancefield serological group may result in underestimation of the presence of S. canis in the human population.- - - - - - - - - - ranking = 2keywords = infection (Clic here for more details about this article) |
8/33. Identification of genotypes of cryptosporidium parvum isolates from a patient and a dog in japan.cryptosporidium parvum (C. parvum) is recognized as a significant pathogen in humans and animals, primarily as a cause of diarrheal illness. Recent genetic and biological studies indicate that C. parvum is not a single species but composed of genetically distinct multiple genotypes. Thus, it is valuable to distinguish between genotypes in the epidemiology of Cryptosporidium infection in humans and animals. Although C. parvum has been detected in humans and animals in japan, the genotype of isolates remains unclear because identification has been performed only by conventional microscopy. We report herein the genotypes of C. parvum isolates distinguished by the polymerase chain reaction (PCR)-based diagnostic method. C. parvum isolates, originally obtained from a patient and a pet dog, were found to have cattle and dog genotypes, respectively.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |

We report a case of complicated, multivesicular, hydatid cysts in the liver and a secondary infection with klebsiella pneumoniae. The cysts were detected in an early stage by ultrasonography and computed tomography and treated successfully with radical resection.- - - - - - - - - - ranking = 5keywords = infection (Clic here for more details about this article) |
10/33. New World leishmaniasis from spain.A 69 year old man living in spain contracted mucocutaneous leishmaniasis involving the nose. The infecting organism was leishmania infantum, which only rarely causes the New World form of the disease. The source of infection was probably a neighbour's dog. The patient began treatment with liposomal amphotericin b but died of pneumonia two months later.- - - - - - - - - - ranking = 1keywords = infection (Clic here for more details about this article) |
