Molecular identification of Cordylobia anthropophaga Blanchard (Diptera: Calliphoridae) larvae collected from dogs (Canis familiaris) in Jos South, Plateau State, Nigeria.

Myiasis-causing larvae were extracted from dogs attending veterinary clinics in Plateau State, Nigeria and subjected to molecular analysis involving polymerase chain reaction amplification of the 28S rRNA gene of blowflies, cloning and sequencing techniques. All larvae were confirmed as Cordylobia anthropophaga Blanchard (Diptera: Calliphoridae) after the initial morphological identification. This is the first molecular identification of any myiasis-causing fly species in Nigeria and may serve as a reliable alternative to morphological identification where samples are not well preserved or dif…

Case series of naturally acquired Plasmodium knowlesi infection in a tertiary teaching hospital.

Plasmodium knowlesi is a simian malaria parasite and is recently recognized as the fifth malaria parasite infecting humans. Manifestation of the infection may resemble other infection particularly dengue fever leading to inappropriate management and delay in treatment. We reported three cases of naturally acquired P. knowlesi in Hospital Universiti Sains Malaysia, Kubang Kerian, Kelantan, Malaysia. Clinical manifestations were quite similar in those cases. Microscopically, the diagnosis might be challenging. These cases were confirmed by polymerase chain reaction method which serves as a gold …

Mycobacterial lesions in fish, amphibians, reptiles, rodents, lagomorphs, and ferrets with reference to animal models.

Mycobacteriosis is a serious disease across many animal species. Approximately more than 120 species are currently recognized in the genus Mycobacterium. This article describes the zoonotic potential of mycobacteria and mycobacteriosis in fish, amphibians, rodents, rabbits, and ferrets. It considers clinical signs; histology; molecular methods of identification, such as polymerase chain reaction and DNA sequencing; routes of infection; and disease progression. Studying the disease in animals may aid in understanding the pathogenesis of mycobacterial infections in humans and identify better the…

Occurrence of Cryptosporidium andersoni in Brazilian cattle.

Feces were collected from 68 dairy cattle, 1 to 12 mo of age, on 12 farms in the municipality of Campos dos Goytacazes, Rio de Janeiro, Brazil, and examined for the presence of Cryptosporidium sp. All samples were subjected to molecular analysis by polymerase chain reaction (nested PCR) of the 18S rRNA. Four positive samples (4.54%) were sequenced and identified as Cryptosporidium andersoni. This species represents a risk for Brazilian cattle because infection can affect cattle productivity. Moreover, C. andersoni is considered a zoonotic species.

Feline herpesvirus 1 and Chlamydophila felis prevalence in cats with chronic conjunctivitis.

The prevalence of Chlamydophila felis and Feline Herpesvirus type 1 was investigated in 30 cats with chronic conjunctivitis, with use of conjunctival swabs and conventional polymerase chain reaction (PCR). In cats with chronic conjunctivitis the DNA of C. felis and FHV-1 was detected in 2 of 30 cats (6.7%) and in 10 of 30 animals (33.3%), respectively. One case of FHV-1 DNA, and none of C. felis was found in control group. There was no case of co-infection with both pathogens.

Detection and clinical relevance of BCR-ABL fusion gene in childhood T-lineage acute lymphoblastic leukemia: a report on 4 cases.

The bcr-abl rearrangement has rarely been reported in T-lineage acute lymphoblastic leukemia and the clinical significance of this translocation is currently unknown. We screened 28 children with T-lineage acute lymphoblastic leukemia at diagnosis by reverse transcription polymerase chain reaction for major and minor break point regions of bcr-abl fusion gene. Four out of 28 patients (14.2%) were bcr-abl positive for the minor breakpoint transcript. One of these patients was refractory to therapy, whereas the other 3 relapsed on therapy.

[Severe disseminated toxoplasmosis with atypical chorioretinitis. A case of primary infection].

The clinical diagnosis of ocular toxoplasmosis is based on clinical features and biological tests: polymerase chain reaction (PCR) and the determination of intraocular specific antibody secretion (Goldmann-Witmer coefficient) on aqueous humor. Older patients may have a higher prevalence of ocular involvement and more severe ocular disease during the acute phase of recently acquired systemic infection because of altered cell-mediated immunity. Moreover, the genotype of the infecting parasite (particularly involving neotropical Type I Toxoplasma gondii strain), appears to be an important determi…

В случае острой лихорадки q с острым острым холестатическим гепатитом.

Минимальная дисфункция печени может быть характерной для острой лихорадки Q, однако о остром остром остром холестатических гепатите сообщается редко. Мы сообщаем о 55-летнем мужчине с острой лихорадкой Q и острым острым холестатическим гепатитом. Он жаловался на лихорадку, желтуху, аскитов и беспокойство при поступлении. Биопсия печени показала наличие компактной грануломы фибрина. Serological titters for C. signetii IgM и IgG были соответственно 2048:1 и 1024:1.

Pulmonary and psoas muscle nocardiosis in a patient with lupus nephritis: a case report and review of the literature.

The incidence of nocardiosis is increasing with the expansion of immunosuppressive therapy and improvement of laboratory diagnostic methods. Nocardiosis could be fatal in the compromised host. Some Nocardia species are known to be multi-drug resistant. Thus, early recognition and identification of Nocardia species are important for patient treatment and outcome. Recently, we treated a patient with pulmonary and psoas muscle nocardiosis in a woman taking prednisolone for lupus nephritis; the isolated organism was Nocardia farcinica identified by polymerase chain reaction-restriction fragment le…

Cutaneous chancroid in a visitor from Vanuatu.

A 23-year-old woman from Vanuatu presented to an Australian hospital with a 3-week history of a non-healing ulcer on the lower leg. A swab was submitted for a multiplex polymerase chain reaction designed to investigate genital ulcerative conditions. Haemophilus ducreyi was detected and the gene product was subsequently sequenced, confirming the diagnosis of cutaneous chancroid. The lesion responded to intramuscular benzathine penicillin. This report adds further evidence that cutaneous chancroid should be considered in the evaluation of skin ulcers in the south Pacific.

Priapism in a castrated cat associated with feline infectious peritonitis.

This report describes a case of feline infectious peritonitis (FIP) in a castrated cat which first presented with the unusual sign of priapism. Laboratory examinations showed increased serum protein content and decreased albumin/globulin ratio. Serum electrophoresis revealed increased alpha 2- and gamma-globulin content. One month after the first examination, the cat died. At necropsy, histopathological evaluation of organs showed inflammatory granulomatous lesions compatible with non-effusive FIP and coronavirus-specific polymerase chain reaction confirmed the diagnosis. FIP antigen was demon…

Detection of Leishmania (Viannia) DNA in blood from patients with American cutaneous leishmaniasis.

The aim of the present study was to investigate the presence of Leishmania (Viannia) subgenus DNA in peripheral blood from patients with cutaneous lesions due to American cutaneous leishmaniasis. The buffy coats from 68 blood samples were analyzed by polymerase chain reaction using the MP1L/MP3H primers. The parasite DNA was detected in 2 (3.4%) out of 59 patients who had amastigotes present in samples taken from lesions. The presence of Leishmania (Viannia) DNA in the blood of these patients indicates hematogeneous parasite dissemination.

A paretic condition in an Anaplasma phagocytophilum infected roe deer calf.

This paper describes a case of Anaplasma phagocytophilum infection in a roe deer (Capreolus capreolus) calf in Norway. The calf was found deserted, paretic, and heavily infested with Ixodes ricinus ticks. It was euthanized and investigated postmortem. Anaplasma phagocytophilum was detected in several tissues by polymerase chain reaction (PCR) and 16S rRNA sequence analyses. Analyses for Borrelia burgdorferi sensu lato and tick-borne encephalitis (TBE) virus infections were negative. This is the first report of a possible paretic condition in A. phagocytophilum infected roe deer.

Extraskeletal Ewing's sarcoma of the hard palate.

Extraskeletal Ewing's sarcoma (EES) is a rare soft tissue tumor morphologically indistinguishable from the more common Ewing's sarcoma of bo … or neurofilaments. The EWS-FLI1 chimeric gene was identified using the nested reverse transcriptase-polymerase chain reaction.

Childhood case of progressive multifocal leukoencephalopathy with improved clinical outcome.

A 6-year-old boy who had been in remission from acute lymphoblastic leukemia for 2.5 years presented with seizures, hemiparesis, visual loss, and white- and gray-matter lesions on cranial magnetic resonance imaging. The diagnosis of progressive multifocal leukoencephalopathy was established on the detection of JC virus DNA by polymerase chain reaction in brain tissue. The patient was administered several anticonvulsants, amantadine, acyclovir, and ganciclovir. He showed partial recovery. This case illustrates the possibility of long-term survival in progressive multifocal leukoencephalopathy w…

[Neurolisteriosis with acute myelitis].

Listeriosis is a bacterial infection with Listeria monocytogenes mostly affecting immunocompromised patients. In every fourth case, the CNS is involved, usually as meningoencephalitis. This case report of an immunocompetent woman represents the first one of neurolisteriosis initially presenting as cervical myelitis and progressing to supratentorial areas of the brain. Diagnosis was based on universal polymerase chain reaction from a cortical brain biopsy, followed by sequencing of the amplified rDNA gene. Under antibiotic treatment with gentamycin and ampicillin, the patient slowly recovered a…

[Association of HLA-DQB1 alleles and dermatomyositis/ polymyositis].

OBJECTIVE: To evaluate further the nature of HLA-DQB1 alleles association with dermatomyositis/polymyositis (DM/PM). METHODS: HLA-DQB1 typing of 52 patients with DM/PM were investigated by polymerase chain reaction-sequence specific primer method, and the frequencies of HLA-DQB1 alleles were compared. RESULTS: It was found that the patients with DM/PM had significantly increased frequency of HLA-DQB1*0401(RR=3.56, P=1.79 10(-3), Pc<0.05). CONCLUSION: The results suggest that HLA-DQB1*0401 gene contribute to genetic susceptibility to DM/PM.

Successful diagnosis using scab for PCR specimen in Tsutsugamushi disease.

We treated a case of Tsutsugamushi disease diagnosed by polymerase chain reaction (PCR) using a scab specimen at the bite site of trombiculid mites. Otherwise the diagnosis could not be confirmed by serum antibody test nor the PCR test of blood. The genome of Rickettsia tsutsugamushi was detected and identified as the Kawasaki serotype strain. An attempt to extract the genome from the scab has not been reported, thus our data suggest that the scab is a useful specimen to confirm the diagnosis of Tsutsugamushi disease.

Ehrlichiosis in a moose calf in Norway.

A case of granulocytic ehrlichiosis in a moose calf (Alces alces) in Norway is described. The animal was heavily infested with ticks (Ixodes ricinus), and died from a Klebsiella pneumoniae septicemia. Examination of blood smears from the calf revealed cytoplasmic inclusions (morulae) typical of infection with Ehrlichia phagocytophila in the granulocytes. Ehrlichia sp. was detected by polymerase chain reaction (PCR) in blood from the calf, and in the ticks. Sequence determination identified it as E. phagocytophila. This is the first report of ehrlichiosis in moose.

Chronic parvovirus B-19 meningoencephalitis with additional detection of Epstein-Barr virus DNA in the cerebrospinal fluid of an immunocompetent patient.

Parvovirus B19 DNA was detected by polymerase chain reaction in the brain biopsy specimen from a 67-year-old immunocompetent woman with severe chronic lymphocytic meningoencephalitis. In addition to parvovirus B19, Epstein-Barr virus DNA was identified in the CSF. Genomic material from Epstein-Barr virus was absent in the brain tissue. Clinical symptoms and CSF pleocytosis improved under long-term corticosteroid-treatment. The aetio-pathogenetic role of parvovirus B19 and the possible meaning of the additionally detected Epstein-Barr virus DNA are discussed.
